Having the wrong sized boiler installed in your home can cause all sorts of issues. A boiler that is too small will be inadequate at heating your home, whereas a boiler that is too big will mean that energy is wasted and you end up paying much more for your energy bills than necessary.
Installing the correct sized boiler for your household will mean that you receive the full benefits of your boiler and that your home is heated efficiently. There are a number of factors that are used to determine the size of the boiler your home needs.
The size of your house
The size of your boiler should reflect the size of your home, with bigger houses needing bigger boilers. This is because large houses are more likely to have more radiators than flats. Typically, the more radiators in your home, the bigger boiler you’ll need.
Hot water requirements
Along with the number of radiators in your home, your hot water requirements will also have an impact on recommended boiler size, and the type of boiler you choose. This includes how many bathrooms your home has and the frequency that you use your showers and water taps.
Insulation, heat loss, and air tightness
The insulation you have installed and the air tightness of your home will have an impact on the size of boiler your property needs. A home with good insulation that is air tight may not need a particularly powerful boiler because the property will retain heat well.
When working out what size boiler you’ll need, the heat loss calculation of the property will also need to be taken into account.
