If you’re looking for a home heating option that’s effective and affordable, then a boiler may be the best choice for you.
We understand that renewable heating systems, like heat pumps, can be an expensive investment. If you’re not ready to commit to such a high price tag, there are boiler options available that mean you can still heat your home and be energy efficient.
Our complete guide below will help you decide which boiler is best for your circumstances and how they can be adapted to reduce the environmental impact.
Below is an example of how the most common boiler type, the combination boiler (or combi) works:
Depending on your boiler type certain parts of the process will be different. For example, although a combi boiler takes in the cold water directly from the mains, a regular boiler has a large tank in the loft full of cold water which flows down to the boiler.
No matter which type you choose though, most modern boilers are now much more energy efficient than they have even been in the past. Manufacturers and government bodies are increasingly pushing innovative technology to try and future proof boiler products. For example, combi boilers, since 2015 are legally required to use condensing technology. This is an inbuilt system which recycles any waste heat that the boiler produces, that would usually escape from the flue pipe, and sends it back in to the boiler cycle.
Manufacturers are also using new technologies to prolong the life of boilers, to reduce waste. One way they encourage this is by including magnetic filters with the purchase of a boiler, which helps to keep internal pipework clear and working efficiently. Many of the top brands also include lengthy warranties and services, to keep your boiler in perfect working condition and reduce the risk of it losing its efficiency.
If you’re unsure of which boiler will best suit your needs, we recommend getting advice from a professional engineer. To save you time and effort, this is something we can help with.

Most boiler types are available in models which allow you to use alternative fuels. For example, if you wanted to avoid the use of natural gas and seek out a lower carbon option, there are electric boilers available, which don’t produce any emissions. The big consideration with these, however, is that most electricity produced by major suppliers is still made by burning fossil fuels.
Issues like this can be overcome with the ability to connect some boiler brands to renewable energy sources, like solar panels. However, there are still a lot of considerations to make when thinking about boiler fuels. Not just in terms of environmental impact, but also the costs and whether it’s accessible to your area and suitable for your home.
Your power source also needs to match the power requirements of the boiler and the needs of your home. To determine that, you’ll need to consider the type of fuel input and determine what size boiler you need.
Natural gas is the most popular and widely used boiler fuel in the UK. This is for two reasons, firstly most homes are already connected to the national gas grid, making it the simplest option logistically. Secondly, when compared to most other fuels, gas has historically been the cheapest option.
As things change globally, prices between fuels fluctuate, but as gas has always been the most convenient, it’s what you will find most homes use. Nevertheless, you may want to consider alternatives to gas boilers.
Thinking about the future, and greener options, you might be surprised to know that your gas boiler may be ready for radical changes. Most modern boilers are now built to be hydrogen ready. Whilst the use of a hydrogen and gas fuel blend is still being developed, it is hoped that this could be the answer to converting most homes in the UK to a more sustainable fuel option.
There would be no need to upgrade your boiler either, as existing boilers connected to the gas grid could receive the blended gas in the same way it usually would. It would mean no additional spend and there would be no disruption to your service.
If you’re interested in this option, be sure to look out for a boiler that is ‘20% Hydrogen Ready’.
Another option for homes using system or regular boilers, which require an additional hot water storage tank, is to consider connecting the cylinder to a renewable energy source, such as solar power, to run the hot water tank. Whilst this doesn’t mean your whole system will be renewable, it is an option to reduce your impact on the environment.
For those whose homes are in more rural areas, or are not connected to the gas grid, there is the option to use oil. This is seen as the best choice if you cannot access gas.
There are some considerations however, as oil needs to be stored in a separate tank somewhere on the property and does need to be manually refuelled.
Depending on the type of boiler you need, you may be able to combine an oil boiler with a renewable fuel source, if you have a solar or wind compatible hot water storage tank.
Electric boilers are often seen as the best fuel source for a boiler, because they do not emit any harmful gases. However, because they run solely on electricity they are technically running on fossil fuels, and this actually makes them less favourable as a renewable option.
Many energy suppliers in the UK are currently working to produce completely renewable electricity. Whilst that will make electric boilers a great option in the future, it’s fair to say that they aren’t particularly good for the environment, at this time.

There are 3 main boiler types, each one is suitable for a different type of home and they all have their own unique benefits.
These boilers are also known as ‘conventional’, ‘traditional’ or ‘heat only’ boilers. They are the oldest boiler style and are usually only found in old houses. The reason they are called ‘heat only’, is because that’s all they do.
The boiler unit itself can only provide heat for your radiators, and therefore an additional hot water tank is needed to supply your domestic hot water.
The regular boiler is very space hungry, as there are 3 separate elements. First you need somewhere for the boiler unit, then additional space for the hot water tank. The third, and largest, element is the cold water feed tanks which are installed in the loft. These are what feed the regular boiler its water supply. For these reasons, it’s not the first choice for most homeowners.
Regular boilers are best used in large homes with plenty of space, and a high hot water demand. They are not, however, recommended unless they are being installed as a direct replacement for an existing regular boiler, as they need a lot of pipework and installation will take time, costing you extra.
System boilers are the ideal choice for anyone with a medium-large sized home and a high hot water demand (meaning multiple bathrooms and lots of people).
System boilers are the upgraded, preferred, options to the regular boiler as they can supply for the same demand, but they take up less space and need much simpler pipework. This is because, unlike the regular boiler, they take their water supply from the mains and eliminate the need for a feed tank in the loft.
They do, however, also need a hot water storage tank in order to provide for the higher demand.
The combination, or ‘combi’, boiler is by far the most popular boiler choice. This is because a combi boiler doesn’t need a hot water tank, and in fact heats your hot water and central heating all from the same unit.
This means a combi is compact, easy to install and takes up less space. It also means it is the quickest and cheapest boiler to have installed. The only thing to note however, is that combi boilers are not always powerful enough to provide for a very high hot water demand. This makes them better situated to small-medium size homes with less than 2 bathrooms.
