Explanation of the importance of energy efficiency when choosing a boiler

Energy efficiency is an important factor to consider when choosing a boiler for your home. Not only can a more energy-efficient boiler save you money on your energy bills, but it can also have a positive impact on the environment. Energy efficiency can be defined as the ratio between the amount of energy needed to perform a certain task, and the amount of energy actually used. In terms of boilers, the energy efficiency is measured by the annual fuel utilization efficiency (AFUE) rating, which is a standard measurement used to indicate how much of the fuel used by the boiler is turned into heat.

When choosing a boiler, it’s important to consider its AFUE rating, as this can have a significant impact on the overall cost of operating the boiler. The higher the AFUE rating, the more energy efficient the boiler is, and the less fuel it will need to use to produce the same amount of heat. For example, if you have a boiler with an AFUE rating of 90%, it will convert 90% of the fuel it uses into heat, while the remaining 10% will be lost as exhaust. On the other hand, a boiler with an AFUE rating of 60% will convert 60% of the fuel it uses into heat, with the remaining 40% lost as exhaust.

In addition to saving money on energy bills, energy efficient boilers also have a positive impact on the environment. The less fuel a boiler needs to use, the less greenhouse gases are emitted into the atmosphere. This is particularly important given the current global concern about climate change. Therefore, choosing a more energy efficient boiler can not only save you money in the long run, but also contribute to a more sustainable future.

Overview of the types of boilers available on the market

There are several different types of boilers available on the market, each with its own unique characteristics and benefits. These include:

1. Combination or Combi Boilers: These are the most popular type of boiler in the UK. They are compact and efficient, providing both central heating and hot water on demand, without the need for a separate hot water tank. They are also easy to install and maintain, making them a great option for smaller homes or those with limited space.
2. System Boilers: These boilers are similar to combi boilers, but they do require a separate hot water cylinder. This allows for a larger hot water storage capacity, making them a good option for homes with high hot water demands, such as those with multiple bathrooms. They also have a compact design, which means they don’t take up as much space as traditional boilers.
3. Regular or Conventional Boilers: These boilers are the most traditional type of boiler and are typically found in older homes. They are separate from the hot water cylinder, which means that they can provide a large amount of hot water and heating at the same time. However, they tend to be larger and less energy efficient than combi and system boilers.
4. Biomass Boilers: these boilers use renewable energy sources, such as wood chips, pellets, and logs, to provide heat. They are an environment-friendly option to traditional boilers and they can also be used in combination with solar thermal systems.
5. Electric Boilers: are also an option, they are easy to install and have low running costs, however they require a good source of electricity and they may not be as efficient as the other options in terms of heating large properties.

When choosing a boiler, it’s important to consider your specific needs and the characteristics of your home. A smaller home with limited space may be best suited for a combi boiler, while a larger home with high hot water demands may benefit from a system boiler. It’s also worth considering your budget, as some types of boilers may be more expensive to purchase and install. Consulting with a professional plumber is always a good idea to get the best advice for your specific case.

Condensing Boilers

Explanation of condensing boilers and how they work

Condensing boilers are a type of boiler that are designed to extract more heat from the combustion process than traditional boilers. They work by using a heat exchanger to extract additional heat from the water vapor produced during the combustion process, which results in greater energy efficiency.

In a traditional boiler, the combustion process produces hot gases that are vented out through the flue. These gases typically have a temperature of around 150-200 degrees Celsius. In a condensing boiler, the hot gases pass through a heat exchanger, where they come into contact with a cooler surface. This causes the water vapor in the gases to condense, releasing additional heat in the process. This additional heat is then used to heat the water in the central heating system, resulting in a higher overall energy efficiency.

Condensing boilers typically have an energy efficiency rating of over 90%, which is significantly higher than traditional boilers. This means that they are able to convert more of the fuel they use into heat, and less is wasted as exhaust. This results in significant energy savings and lower heating costs for the homeowner.

One of the key features of condensing boilers is that they have a secondary heat exchanger, which is designed to recover heat from the flue gases that would be otherwise wasted in traditional boilers. This secondary heat exchanger is able to extract heat from the flue gases, which is then used to heat the water in the central heating system, resulting in a higher overall energy efficiency.

Condensing boilers also have a modulating burner, which means that it can adjust the amount of fuel it burns based on the heat demand, resulting in even greater energy savings.

It’s important to note that condensing boilers require proper installation and maintenance, if not they may not work to their maximum efficiency and could even damage the system. Therefore, it is recommended to consult with a professional plumber when considering the installation of a condensing boiler.

Comparison of energy efficiency ratings for condensing boilers vs. non-condensing boilers

The energy efficiency of a boiler is typically measured by its annual fuel utilization efficiency (AFUE) rating. This rating is a standard measurement used to indicate how much of the fuel used by the boiler is turned into heat.

Condensing boilers typically have an AFUE rating of 90% or higher, which means that they are able to convert 90% or more of the fuel they use into heat. This is significantly higher than non-condensing boilers, which typically have an AFUE rating of around 80%. This means that non-condensing boilers are only able to convert 80% of the fuel they use into heat, with the remaining 20% lost as exhaust.

For example, a non-condensing boiler with an AFUE rating of 80% would waste 20% of the fuel it uses, while a condensing boiler with an AFUE rating of 90% would waste only 10%. This translates into significant energy savings for the homeowner over time, as well as a lower environmental impact.

It’s important to note that the AFUE rating is a seasonal average, which means that it takes into account the boiler’s performance over an entire heating season and it doesn’t reflect the boiler’s performance during peak usage hours, when the boiler may not be operating at its peak efficiency.

Another important aspect to consider is that the energy efficiency of a boiler not only depends on the type of boiler but also on how well it’s been installed and maintained. A non-condensing boiler that has been installed and maintained properly can have a similar energy efficiency as a condensing boiler that hasn’t been installed and maintained properly.

In summary, condensing boilers have a higher energy efficiency rating than non-condensing boilers, typically above 90% which means that they convert more of the fuel they use into heat and waste less as exhaust. It’s important to keep in mind that the energy efficiency of a boiler also depends on the installation and maintenance of the system.

Discussion of modulating burners and their impact on energy efficiency

Modulating burners are a feature found in many modern condensing boilers that can help improve energy efficiency. A modulating burner is a device that controls the amount of fuel that is burned in the boiler based on the heat demand. This allows the boiler to adjust its output to match the heating requirements of the home, resulting in greater energy efficiency.

When a home’s heating demand is low, a modulating burner reduces the amount of fuel that is burned, which in turn reduces the amount of energy that is used. Conversely, when the heating demand is high, the modulating burner increases the amount of fuel that is burned, providing more heat to the home. This ensures that the boiler is always operating at the optimal level, which results in greater energy efficiency.

Modulating burners also help to improve the overall comfort level in the home by maintaining a consistent temperature. This means that the boiler is not constantly turning on and off to try and maintain a certain temperature, which can cause temperature fluctuations and drafts.

Modulating burners are also able to adjust the air/fuel ratio to ensure that the combustion process is as efficient as possible, which also helps to improve energy efficiency.

In summary, modulating burners are a feature found in many modern condensing boilers that can improve energy efficiency by adjusting the amount of fuel that is burned based on the heating demand of the home. This ensures that the boiler is always operating at the optimal level, which results in greater energy efficiency and improved comfort level in the home.

Renewable heating options in the UK explained

As concerns about climate change and the need for a sustainable living continue to grow, more and more people are looking for ways to reduce their carbon footprint and switch to renewable energy sources. One area where this is particularly relevant is in the way we heat our homes. In the UK, the majority of domestic energy consumption is used for heating, making it a key area for consideration when it comes to sustainability. In this article, we will explore the various renewable heating options available in the UK, including solar thermal, air source heat pumps, and ground source heat pumps. We will also discuss the benefits and drawbacks of each option, as well as the potential cost savings and environmental impacts. Whether you’re looking to reduce your reliance on fossil fuels or simply save money on your energy bills, this article will provide valuable information on the renewable heating options available in the UK.

Heat Pumps

Heat pumps are a type of renewable energy system that can be used for heating and cooling buildings. They work by transferring heat from one place to another, rather than generating heat directly like a traditional heating system. There are two main types of heat pumps: air source heat pumps and ground source heat pumps.

Heat pumps are a highly efficient and environmentally friendly way to heat and cool buildings. They can save up to 50-70% on energy bills compared to traditional heating systems, and they produce very low carbon emissions. They are also easy to maintain and have a long lifespan. However, they can be more expensive to install than traditional heating systems, and they may not be suitable for all buildings or climates.

Air source heat pumps

Air source heat pumps use the air outside a building to heat or cool the interior. They work by extracting heat from the air and transferring it inside, or by absorbing heat from inside a building and releasing it outside. Air source heat pumps are relatively easy to install and can be used in both new and existing buildings.

Ground source heat pumps

Ground source heat pumps, also known as geothermal heat pumps, use the ground or ground water as a source of heat. They work by extracting heat from the ground or ground water and transferring it into a building, or by absorbing heat from inside a building and releasing it into the ground. Ground source heat pumps require a ground loop, which can be installed through horizontal trenches, vertical boreholes, or a pond or lake. They are generally more efficient than air source heat pumps and can be used in both new and existing buildings.

Biomass boilers

Biomass boilers are a type of heating system that use organic materials, such as wood chips, wood pellets, or logs, as fuel. These boilers are designed to burn the fuel in a controlled and efficient manner, producing heat that can be used to heat a building or hot water. Biomass boilers are a renewable energy source, as they use a sustainable fuel that can be replenished.

There are several benefits to using biomass boilers. They are a renewable energy source, they can save up to 30% on energy bills compared to traditional heating systems, and they produce low carbon emissions. Biomass boilers are also flexible, as they can be used to heat a building or produce hot water. However, there are also some drawbacks to consider, including the initial cost, the need for fuel storage, and the requirement for regular maintenance. The cost of a biomass boiler depends on the size of the system, the type of boiler, and the fuel used, with prices ranging from £9,000 to £20,000.

Solar water heating systems

Solar water heating systems use the energy from the sun to heat water for domestic use. These systems consist of solar panels, called collectors, which are installed on the roof or walls of a building. The collectors absorb the energy from the sun and transfer it to a fluid, which is circulated through the collectors and into a storage tank. The heat from the fluid is then transferred to the water in the storage tank, raising the water temperature.

There are two main types of solar water heating systems: passive systems and active systems. Passive systems use natural convection to circulate the fluid through the collectors and into the storage tank, while active systems use a pump to circulate the fluid. Active systems are more efficient than passive systems, but they are also more expensive to install.

Solar water heating systems are a highly efficient and environmentally friendly way to heat water for domestic use. They can save up to 70% on water heating costs, and they produce no carbon emissions. They are also easy to maintain and have a long lifespan. However, they may not be suitable for all locations, as they require a south-facing roof or wall with sufficient sunlight. Solar water heating systems can also be more expensive to install than traditional water heating systems, although the initial cost can be offset by the energy savings.

Heat networks

Heat networks, also known as district heating systems, are a type of heating system that uses a central plant to produce heat, which is then distributed to multiple buildings through a network of underground pipes. Heat networks can use a variety of energy sources, including natural gas, renewable energy, and waste heat from industrial processes, to produce the heat.

Heat networks have several benefits, including energy efficiency, cost savings, and low carbon emissions. They are also easy to maintain and have a long lifespan. However, there are also some drawbacks to consider, including the initial cost of installation and the need for a central plant. Heat networks may also not be suitable for all locations, as they require a sufficient demand for heat in the area.

Heat networks are becoming increasingly popular as a way to heat buildings in a more sustainable and efficient manner. They are particularly useful in urban areas, where there is a high demand for heat and limited space for individual heating systems. Heat networks can be used to heat a variety of buildings, including residential, commercial, and industrial.

In conclusion, there are many renewable heating options available in the UK that can provide a more sustainable and cost-effective way to heat buildings. Options such as heat pumps, biomass boilers, solar water heating systems, and heat networks can all use renewable energy sources or waste heat to produce heat, reducing reliance on fossil fuels and reducing carbon emissions. While these options may have a higher initial cost compared to traditional heating systems, they can save homeowners money on energy bills in the long run and contribute to a more sustainable future. It is important to carefully consider the different options and choose the one that best fits the needs and circumstances of the building.

Ground Source Heat Pump Systems Explained for London Residents

Ground Source Heat Pump Systems Explained

A ground source heat pump takes advantage of the heat in the ground to provide your home with reliable heating and hot water. Temperatures underground remain between 10 and 15 degrees Celsius regardless of the time of year, so the system can be utilized all year round.

How ground source heat pumps work

Ground-source heat pumps are composed of 3 different components that work together to transfer heat from the ground into living quarters.

Ground loop

This is a pipe hidden underground, usually underground in the garden, either in a trench or a vertical burrow. A trench goes 2 meters below ground level, while boreholes are drilled deeper down to between 15 and 150 meters. More heat can be retrieved from the ground with longer loops, but available real estate will determine the most suitable area for the extraction of underground heat.

The mixture going around these pipes will be both water and antifreeze. The natural heat from below is absorbed by the fluid, which then goes by way of a heat exchanger to warm a heat pump.

Heat pump

Heated water is passed throughout the house to radiators or underfloor heating systems. If the system is being used to warm water, then the water is sent to cylinders for water storage. A functional Heating system is created when these components are coordinated.

Horizontal trenches and vertical boreholes

The pipes can be installed horizontally or vertically, depending on the space available on your property. Vertical boreholes typically go straight down into the ground and can be as long as 15 – 100 meters. Horizontal systems are shallower but can cover more area. Vertical systems are typically more expensive initially, but they should pay off in the long run.

What is the best heating system for a heat pump?

The heat generated by a ground-source heat pump is best suited to underfloor heating. Radiators usually need to be heated up to about 70 degrees in order to heat rooms, whereas underfloor heating typically operates at 30 degrees. If you’d like radiators as opposed to underfloor heating, you may need to install larger ones.

How efficient are ground source heat pumps?

While they do require electricity, a fully insulated ground-source system can provide roughly 3-4 more kilowatts of energy for every kilowatt of electricity used. That equates to an efficiency of roughly 300 per cent.

Ground source heat pumps can be an efficient and cost-effective method of heating your home, and you may be able to receive government funds to help offset the installation cost.

How to maintain a ground source heat pump

While a ground-source heat pump needs little in the way of upkeep, it’s crucial to watch how it’s functioning. The Ground Source Heat Pump Association suggests that initial safety inspections are not required, though the system should be serviced every five years.

Manufacturers may require their ground-source heat pumps to undergo service maintenance during the warranty period, so always be sure to consult your manufacturer.

How long do ground-source heat pumps last?

The lifespan of a heat pump depends on the kind and how well it continues to be maintained. Some heat pumps may last as long as twenty-five years, but others may need to be replaced after only ten years. Regardless of the heat pump, a ground source heat pump is among the best long-term investments you can make for your house because it can efficiently heat your property for many years.

Is a ground source heat pump right for your home?

First, you’ll need to ensure that your house is of the correct size for a ground source heat pump installation. your house must have enough space in your garden for either a horizontal trench or vertical borehole, and this may require access for various machinery.

It is essential that a well-insulated and draught-free home be utilized to make the most of a ground-source heat pump’s efficiency.

Boiler Efficiency Explained

Upgrading your boiler to a more efficient model can save you money on your monthly fuel bill. Older, less efficient boilers waste energy and money, while newer models are much more efficient and cost-effective. By upgrading to a new boiler, you can lower your monthly fuel costs and improve the comfort of your home.

What is boiler efficiency?

When it comes to boiler efficiency, there are a few key factors that play into how much heat your home will get for the amount of fuel you put in. One of the most important is the boiler’s ability to turn that fuel into usable energy without wasting any of it. This is determined by various factors, including the boiler’s design and the quality of its construction.

What is ErP?

The Energy Related Products Directive (ErP) is an EU directive that phased out inefficient appliances. The directive sets minimum efficiency standards for products such as boilers, air conditioners, and refrigerators. Products that meet the ErP standards are labelled with an energy efficiency rating from A to G.

Appliances that are not ErP compliant will eventually be phased out and replaced with more efficient models. If you’re shopping for a new boiler, look for one with an A or B energy efficiency rating.

ErP directive applies to heating products in Europe and has two benefits.

• Clear energy labelling allows consumers to choose the most energy-efficient products, reducing carbon emissions and saving money on energy bills.
• The Ecodesign Directive is a European Union directive aimed at increasing the energy efficiency of products. The directive was introduced in 2005 with the aim of reducing greenhouse gas emissions, and it has been amended several times since then. In September 2015, it required that products meet higher energy efficiency standards

Boiler manufacturers and retailers have a responsibility to ensure that their products are accurately labelled. This means that the boiler’s efficiency should be clearly stated so that consumers can make an informed decision about which model to buy. The installer who fits your new boiler is also responsible for ensuring that it is efficient. If you’re not happy with the efficiency of your boiler, you should contact the manufacturer or installer to discuss your options.

What is SEDBUK?

The ErP ratings were introduced to replace the SEDBUK ratings because the ErP ratings are a more accurate way of measuring a boiler’s efficiency. The SEDBUK ratings only measure the efficiency of the boiler when it is in standby mode, while the ErP ratings measure the efficiency of the boiler when it is actually heating your home.

What is Boiler Plus?

Boiler Plus is a government scheme that requires new gas boiler installations to meet certain requirements for increased efficiency. This is designed to help homeowners save money on their energy bills and reduce their carbon emissions.

One of the main benefits of Boiler Plus is that it encourages homeowners to upgrade to more energy-efficient boilers. A newer, more efficient boiler can save you up to £340 a year on your energy bills, so it’s definitely worth considering if your boiler is getting old and inefficient.

Boiler Plus also introduces some new requirements for boilers, such as the need for a carbon monoxide alarm and an automatic shut-off in case of high levels of carbon monoxide. This is a great safety measure that will help to protect you and your family from the dangers of carbon monoxide poisoning.

Overall, Boiler Plus is a great initiative that can help you save money on your energy bills and make your home safer.

The Boiler Plus initiative sets minimum requirements for the efficiency of gas-fired boilers. These requirements must be met in order to sell boilers in the UK. The initiative was introduced in response to the Energy Performance of Buildings Directive, which requires all new buildings to achieve a minimum level of energy performance.

Gas boilers must be at least 92% efficient in order to meet the minimum requirements of the Boiler Plus initiative. However, there are a number of ways to improve your boiler’s efficiency and lower your heating bills.

Benefits of an efficient boiler

Replacing an old, inefficient boiler with a new, more efficient model can result in significant savings on your heating bills. Newer boilers are more efficient at converting fuel to heat, so you’ll use less energy to keep your home warm. Additionally, newer boilers have been designed to produce less pollution, so you’ll be doing your part to help the environment.

ways to make your boiler more efficient

1. Annual boiler service

Having your boiler serviced every year is important to keep it running efficiently. A service can help to spot potential problems and fix them before they become more serious and expensive to repair. It can also improve the efficiency of your boiler, helping to lower your heating bills.

2. Bleed the radiators

Bleeding your radiators is a process of releasing air from the radiator using the bleed valve. This is usually done when the heating system is first installed and then again every two years. If you don’t bleed your radiators, they will eventually become blocked and the energy required to heat your home will be increased.

3. Keep the water pressure topped up

A boiler operates more efficiently with a higher pressure because it is able to create more heat. This is due to the increased thermal energy that is created by the combustion process. The increased pressure allows for a greater volume of gas flow, which helps the boiler reach its optimal operating temperature sooner. Additionally, a higher pressure helps to prevent scale formation on the heat exchanger.

4. Insulate cylinder and pipes

Making sure your property is well insulated is key to keeping your home warm and improving boiler efficiency. This includes insulating the cylinder and pipes, as these are often the areas that lose the most heat. You can also install insulation around your doors and windows, and make sure to seal any cracks or gaps that may let heat escape.

Conclusion

Improving boiler efficiency can save you money on your energy bills and help the environment. There are many ways to make your boiler more efficient, so be sure to explore all of your options. If you’re looking for a new boiler, consider investing in an energy-efficient model that will save you even more money in the long run. Thanks for reading!

Ground Source Heat Pumps (Geothermal Heating) Explained

A ground source heat pump also called “geothermal heating” uses the earth as a way to provide heating and cooling. The system can be used both in new construction and for retrofitting into existing buildings that have an available well near the building.

How do ground source heat pumps work in the UK?

In the UK, ground source heating systems work by using a network of pipes that are installed in trenches around your home. The system works as follows:

Water is pumped from an underground well and flows throughout the buried piping loops via a heat exchanger where it picks up a large amount of heat energy from the surrounding earth.

The water then flows through another heat exchanger inside your home’s furnace where it heats your home during winter months or cools it during summer months depending on its position within the heating cycle. Then, after having picked up enough energy, the warm or cold water returns back to be reused for another cycle.

What is the source of heat in the ground?

Heat is transferred from the earth to water in a ground source heating system through two modes:

The first mode of heat transfer is conduction, which happens as warm soil conducts its thermal energy throughout an underground loop system. The second method is convection and works with wind currents that travel upward into your home’s air vents where they then exit out of another vent located on top of your roof. This causes warmer or cooler air to circulate within your home depending on the season and time of day.

How much land do you need for a ground source heat pump UK?

Ground source heating systems can be installed with as little as half an acre of land. However, the more area you have available for installation, the better your system will perform because it is able to exchange heat energy over a larger surface area which results in greater efficiency and performance throughout the winter months.

How much does a ground source heat pump cost?

A geothermal heating system can be installed for around £25,000 including the costs of installation and construction. However, you should bear in mind that your energy bills will go down because the system consumes very little or no electricity, resulting in lower utility expenditures throughout the winter months. In addition to this, When you’ve paid off your initial investment, after roughly ten years, you’ll be able to enjoy lower monthly energy expenses, there are no further expenses as it runs fully on its own without requiring any large-scale maintenance at all throughout the rest of its lifetime.

What are other benefits of using a ground source heat pump UK?

It has been estimated by several studies conducted by KEMA Laboratories that a ground source heating system can reduce your carbon footprint by up to 50% when used in place of traditional gas or electric-based systems.

It has also been reported that using these geothermal systems will help you save money on expensive winter heating bills while at the same time protecting our environment from harmful greenhouse gases created by burning fossil fuels for energy purposes. Ground source heat pumps are an excellent alternative, both environmentally friendly and cost-effective way of providing sustainable space conditioning solutions throughout the UK.

How deep are ground source heat pipes?

Most ground source heat pump systems in the UK are installed with pipes that range anywhere from three to six feet deep. The deeper your system’s piping is buried underground, the better it will perform because of higher temperatures and greater thermal conductivity found at these depths.

Soil type:

Ground source heating systems can be used on any soil type including clay, rocky or sandy soils as long as there is enough room for trenches to house pipelines. Most installations require an area that has a minimum depth of 25 metres and widths ranging between two and five meters (six-15 ft). However, you should bear in mind that some regions may place restrictions on installing geothermal heat pumps due to local ordinances regarding how close wells must be from water sources. Make sure you research your area’s policies before installation to avoid any unnecessary setbacks.

How long does a ground source heat pump last?

A geothermal heating system installed in the UK is expected to last anywhere from 25-35 years, however; this does depend on installation costs and its overall condition. A ground source heat pump works best when it is located where there are large areas of open land for soil exchange with no obstructions along the way. Deep boreholes tend to work better than shallow ones because they can take advantage of higher temperatures found at greater depths which provides more consistent performance throughout the winter months.

Do ground source heat pumps work in cold weather?

Ground source heat pumps are designed to operate in even the coldest climates making them perfect for UK installations. During winter months, you can expect temperatures of around -15 degrees Celsius (about five degrees Fahrenheit) which is completely normal and within operating ranges of these systems.

These geothermal heating units work best when they’re installed on flat land with no obstructions along the way as well as spaces large enough to take advantage of high surface area exchange between soil and pipeline trenches so that it can take full advantage during colder weather conditions without any problems or interruptions whatsoever.

What does a ground source heat pump look like?

A ground source heat pump system will typically have several components including an outdoor unit for condensation collection, ventilation, compressor, heat exchanger and an indoor unit for warmth distribution. The outdoor condensing units are usually found in the rear of buildings or on rooftops while the indoor units are mounted at ceiling level so that warm air can be distributed throughout homes via ductwork installed within walls.

Conclusion 

A ground source heat pump is a way to keep your home warm and cosy while reducing the energy needed for heating. This blog post has provided you with some tips on how to choose the best system, as well as what it costs and other important information about installing a heat pump in your own home!

Why Choose a Smart Thermostat?

Smart thermostats are a new trend that allows you to control your heating on the go from your phone, tablet or other devices. They’re touted as a great way to save cash, but they’re not cheap – so whether one will save you money depends on how you use it and what type of home you have.

What can smart thermostats do?

Smart thermostats allow you to control your heating from a device that is not at home. It means that you can take charge of your heating from another location whether it’s work or on the go. What’s more, many smart thermostats let you programme in advance so you can set your heating so it starts to warm up before you get home from work.

How are they different from standard thermostats?

Traditional programmable thermostats and smart thermostats (also known as programmable thermostats with ‘connected’ or ‘touch screen’ displays) are both fitted the same way. The only difference is that smart thermostats can be controlled remotely, which makes them perfect for letting you take charge of your heating even when you’re not at home.

Will it work with my boiler?

A simple way to tell is by looking at the type of boiler that you have. If it’s an electric boiler, then a smart thermostat will not help in any way. If it’s a gas, oil or solid fuel boiler, then the answer is ‘maybe’. This is because they can support most heating systems in homes in the UK and Ireland. Nevertheless, some boilers may need a little more work than others in order to get them to talk to your smart thermostat.

How much do smart thermostats cost?

A smart thermostat will cost on average £160-£350, which may seem expensive but some estimate that they save up to £130 per year so it can work out more than paying for itself.

But if your home is more energy-efficient, for example, it has double glazing or loft insulation, then you are less likely to see the savings that others make.

How do I control it?

Smart thermostats can be controlled via an app on your phone or tablet. This means you can think about your heating needs even when you’re not at home. You can also save money by programming your heating to come on only when you need it, like when you’re coming home from work.

Can smart thermostats help you save money?

Saving money is always a good thing, so are smart thermostats worth the investment? It’s hard to say for sure because it depends on how much you use your thermostat. But if you use it frequently it could save you up to £130 per year. However, if you have an electric boiler then a smart thermostat won’t help you at all. So even if you don’t use it a lot, a smart thermostat combined with a gas or solid fuel boiler could still save you money.
