Choosing the right boiler

The size of the kW of the boiler is chosen by looking at the size of the house in m2, the age of the house and whether the house is detached, semi-detached, in a town or in the country. The age of the house. e.g. a house aged 20-30 years will often use about 1 kw per 10 m2 so e.g. 180 m2 house = 18 kw. Newer houses use less and older houses use more.
