Heat Pumps
Low-carbon heating has to feel good, not just look good on paper. Performance depends on the building, the emitters, the controls, the flow temperatures and the quality of the installation.
What good design looks like
Room-by-room heat loss calculated before equipment is selected
Unit matched to the design heat load — neither under nor oversized
Radiators or underfloor sized for low flow temperatures
Weather compensation, zoning and hot-water schedules set to real routines
Noise, siting and access considered from the outset
Comfort check
Your design should explain expected room temperatures, flow temperatures, hot-water performance and any radiator or cylinder changes required.
Worth knowing
Running-cost estimates are guidance, not guarantees. Weather, occupancy, settings and the building itself all materially affect the result.
How we approach it
Fabric first, right-sized to the design heat load, and set up for genuine comfort at low flow temperatures.
- 01
Fabric first
Understand heat loss, insulation and air leakage before selecting equipment.
- 02
Right-sized
Match the unit to the design heat load, avoiding both undersizing and unnecessary oversizing.
- 03
Low-temperature
Size emitters to deliver comfort efficiently at lower flow temperatures.
- 04
Controlled
Set up weather compensation, zoning and hot-water schedules around how you actually live.
