Free Heat Loss Survey Tool - What Size Heat Pump?
I've created this interactive widget where you can calculate your homes heat loss from daily gas data (and outside temperature).
Useful for gas boiler owners to get a ballpark idea of their heat loss using data from very cold days.
This article provides a free heat loss survey tool for homeowners with gas boilers and smart meters to estimate their home's whole-house heat loss using real energy data from cold weather. The tool helps determine the size of a heat pump needed by converting gas readings into a design heat loss figure in kilowatts. It is not a replacement for a full house survey by a skilled engineer but serves as a starting point. The tool covers the conversion of gas into useful space-heating energy, deriving a whole-house heat loss rate, and applying it to a cold design temperature to output a design heat loss in kilowatts.
