Your question
How much heat does my premises need, and how much will it cost?
A café, shop or small office should be comfortably heated, but without wasted spending. TermoFlo works out how many kilowatts of heat the premises lose and which fuel is more cost-effective — so you can plan the budget precisely.
Go to the heat-loss calculatorHow it works — three steps
- 1
What you enter
The size of the premises, the desired indoor temperature, the design outdoor temperature, and the insulation of the walls, roof, floor and windows.
- 2
What you get
The premises' heat loss in kilowatts and a cost comparison of different fuels for that demand.
- 3
The decision you make
Choose heating of the right power and budget for the most cost-effective fuel.
A worked example with real numbers
A café of about 50 m²
For a small café of roughly 50 m² with large windows, heat loss can reach about 5 kW. That's a guide for the heating power, while the fuel comparison shows where the owner will save over the season.
