Can Heat Loss Determine Boiler Size?
When finding a suitable boiler for your property, the size of your house is typically used as a factor in considering the right size boiler required.
However, more recently, a gas-safe engineer
can also calculate your home's heat loss as a better way to determine the most effective and efficient boiler size.
Multiple factors are taken into account when making a heat loss calculation, which includes the floor area, the number of radiators in your property, the type and number of windows, the quality of insulation and a few other aspects that can cause heat to be lost from your home.
Taking these factors into account, a calculation will then be used to determine how much heat your home will lose on the coldest day of the year so you can discover the most optimum size of the boiler.
Other Boilers Types for Consideration
Did you know that the type of fuel available in your home will affect the size of the boiler?
That's because different fuels can vary in terms of efficiency, as most properties across the UK commonly use gas boilers, which offer the most significant level of efficiency.
However, there are houses that are not connected to a mains gas supply, meaning that homeowners have a choice between an oil-fired
or LPG (liquefied petroleum gas)
heating system instead.
Furthermore, some modern boilers are built ready for future renewable energy sources like solar panel
and heat pumps
, which should be considered when deciding the right size boiler for your home.
Electric boilers are another option for homeowners. However, electric boilers are best suited for smaller homes as they are unable to meet the demands of bigger properties.
We briefly mentioned that the number of bathrooms on your property will vary with the size of the boiler required. It is important to remember that the frequency of running a bath or shower will also impact the size of the boiler you need.
Additionally, suppose you have a lot of people living in your home. In that case, the demand for hot water and heating will be higher - requiring a larger kW of the boiler.
