We understand you want to know how much a Sunflow heating system is going to cost to run.

We base our calculation on a number of assumptions, so we can't guarantee our running cost estimates, but you can use them as a guide.

 Grab pen, paper, tape measure  and note down your room dimensions

Tell us where to send your calculation and your home characteristics

Photograph your paper (or fill in the details if your writing isn’t legible) and send!

Try to be as precise as possible when measuring, but it doesn't have to be perfect.

The more information you can give us about your home, the more accurate our running cost calculation will be.
