Heat loss calculations for commercial buildings

Know how much heat your building needs before you choose a system. A heat loss calculation sizes your heating correctly, whether you are fitting a boiler or a heat pump.

What is a heat loss calculation?

A heat loss calculation works out how much heat each space loses through its walls, roof, floors, windows and ventilation. The result tells you how much heating output you need to stay comfortable on a cold day.

Why it matters

Oversized systems cost more to buy and run, and undersized systems leave people cold. For heat pumps in particular, an accurate calculation is essential, because they work best when sized correctly.

What you receive

  • A room-by-room heat loss figure
  • A recommended system size
  • Advice on insulation or emitter upgrades that could help
