Our homes need heating, to overcome the temperature differential between indoors and outdoors and to replace heat lost through the walls etc. The colder it is outside, the more heat is lost and the more we have to heat the building, to replace that heat, especially in the winter, when the amount of heat loss is at its highest level.

Weather compensation controls work by ensuring that the boiler burns the right amount of fuel required to match the heat lost from the building. The house will always maintain the desired temperature for maximum comfort, with no need for room thermostats.
