Factors to consider when choosing a boiler

There are a number of different factors that go into choosing a boiler, whether it’s time for a replacement, or it’s your first one. These factors can determine how well the boiler works in your home, and how much energy it will consume. By taking a careful look at each of these considerations, you’ll be on your way to choosing a boiler that best fits your needs.

The size of your home is a huge factor with regards to the size of the boiler that is required. A boiler is measured in British Thermal Units (BTU), which is the amount of energy that is needed to increase a pound of water by exactly one degree Fahrenheit. It is possible to figure out the BTU requirement for your home based on its size, where you live, the number of doors and windows you have, and how well insulated the building is. Generally, a 50 BTU per square foot is the rule for homes in cold climates, and 35 BTU per square foot is more appropriate for buildings in warmer climates. If your boiler is not the correct size, then it will not be able to adequately heat your home, or will overheat it and waste a lot of energy. Some types of boilers generally take up less space. For example, liquid petroleum gas (LPG) boilers are smaller than oil boilers, making them more convenient for homes with limited space.


Another important factor when it comes to choosing a boiler is how efficient it is. Around 60% of CO2 emissions for homes using gas central heating is accounted for by the boiler, so if your boiler is not particularly efficient, it will waste a lot of energy and cause the cost of heating your home to go up exponentially. New boilers are generally more efficient, and installing an A-rated high efficiency condensing boiler in place of your old one could save you over £300 a year. A boiler with a good heating control system is essential for efficiency, as it means that you can choose which rooms to heat at particular times. This prevents you from wasting energy on heating rooms you won’t be using.

Requirements for Venting

It is critical to look at the venting requirements for a boiler, and ensure that you are able to meet them. If there is nowhere to vent a boiler, then it will be useless. Some boilers vent through the chimney, while others will need to push used air through a vent in a wall. Choose the boiler that will work best with your home.


Around 4.3 million households in the UK are not on the gas network. There are a number of alternatives to natural gas, including oil, wood, and LPG. Different fuel types have their own pros and cons. While wood burning stoves can be extremely convenient for those with access to lots of wood in their local area, buying wood can become costly, and the stoves themselves are usually quite expensive. Oil is generally more efficient than natural gas, but LPG is even more efficient. LPG also has the lowest carbon emissions when compared with other fossil fuels, as well as having lower sulphur emissions and less soot.
