UK property heat loss calculator

Estimate room-by-room space-heating demand and compare the result with a Daxom 12 kW electric boiler. Enter your room dimensions and construction assumptions below, then download your report.

Using your heat loss estimate to choose an electric boiler

This calculator provides an indicative estimate for planning. Confirm room dimensions, exposed surfaces, U-values and the local outdoor design temperature before using the result. A heating professional should verify heat loss, emitter sizing, hot water requirements and electrical supply suitability.

Next, use our electric boiler selector to explore the Daxom range, or contact Daxom for advice. A space-heating estimate alone does not confirm which boiler is suitable for your property.
