Quick Whole House Heat Loss Estimator
Fast. Accurate. Ready for Quotes.
At Heat Engineer Software, we understand that not every project starts with a full room-by-room heat loss calculation — especially when you're preparing an initial quote or assessing system suitability. That's why we've developed the Quick Whole House Heat Loss Estimator : a rapid tool designed to give installers a reliable snapshot of a property's total heat loss in just five minutes.
How Our Software Supports Quick Heat Loss Estimates

Using a streamlined set of inputs, the Quick Estimator calculates the total heat loss of a property — ideal for early-stage system sizing or pre-sales discussions. The process typically takes under 5 minutes to complete, with many users reporting accuracy within 5% of a full room-by-room calculation.
This makes it a powerful tool when you need fast, reliable data to:
- Support a heat pump or boiler quotation
- Assess system suitability for low temperature heating
- Give customers an early indication of required system size
- Inform upgrade decisions like insulation or window replacement
