Heat-loss calculations
Understanding how each property loses heat and what it genuinely needs.
Air-source heat pumps in Cardiff
SMC installs Daikin air-source heat pumps across Cardiff and surrounding CF postcodes, combining established heating experience with careful system planning and straightforward advice.

Committed to learning
A heat pump is not simply a box fitted outside. Comfort and efficiency depend on understanding the property, its heat loss, the existing system and the temperatures needed to heat each room.
That is why our continued development goes beyond fitting equipment. We keep building our knowledge of heat-loss calculations, system design, radiator sizing, flow temperatures and real-world performance—the same improve-every-day approach that has shaped SMC since 2011.

The SMC approach
