Comfort starts with the calculation—not the heat pump.
We design the complete heating system around the property’s room-by-room heat demand, emitters, hot water requirements and how the household lives.
Correct sizing protects comfort and efficiency.
A heat pump should not be selected from floor area alone. We assess how heat moves through every room, the building fabric, ventilation losses and the temperatures needed from radiators or underfloor heating.
This gives us the evidence to choose the unit, cylinder, controls and emitter changes as one complete system.
Measured, calculated and explained.
Home survey
Dimensions, construction, insulation, windows and existing heating.
Heat-loss calculation
Room-by-room demand at the design outdoor temperature.
Emitter assessment
Radiators or underfloor heating checked at lower flow temperatures.
System selection
Heat pump, cylinder, buffer, controls and hydraulic arrangement.
Commissioning
Flow rates, weather compensation, controls and customer handover.
The details behind a dependable installation.
Room heat losses
A calculation for each habitable space—not one broad estimate for the whole house.
Heat pump output
Equipment selected to meet the design load under the required operating conditions.
Radiator schedule
Existing emitters assessed with proposed upgrades clearly identified.
Hot water sizing
A cylinder chosen around occupancy, usage and available installation space.
Controls strategy
Heating zones, weather compensation and hot-water control planned together.
Grant support
Guidance through the Boiler Upgrade Scheme process where the installation is eligible.
