Your question
Which of the two homes will be cheaper to heat?
You're choosing between two flats or houses, and price isn't the only thing that matters: heating bills can differ several times over. TermoFlo works out the heat loss of each option and the indicative fuel cost, so you can compare them fairly.
Go to the heat-loss calculatorHow it works — three steps
- 1
What you enter
The size and insulation of each home, plus the fuel it's heated with.
- 2
What you get
The heat loss in kilowatts for each option and an indicative monthly heating cost.
- 3
The decision you make
Choose the home that's cheaper to run, with the numbers side by side.
A worked example with real numbers
Two flats of the same size
Two 60 m² flats look identical, but one is better insulated: its heat loss is about 3 kW versus 5 kW for its neighbour. Over a heating season that's a noticeable difference in the bills — and that's exactly what the calculation shows.
