What size boiler do I need?

The size of boiler needed will depend on the type of system you have installed, the size of your house, your water usage, budget and preference. A conventional system, or system boiler will require a 12- 15KW boiler for a small house, 15-24 KW boiler for medium size house or a 24- 36 KW boiler for a large house. Lewis Heating and Boiler Installation Services use a complex set of calculations to determine the exact size of the boiler. It is important to size a boiler correctly, if the boiler is too small, you will end up with a cold property, too large and the boiler will not run efficiently.
