FSH HP Master Air-to-Water Heat Pump
Multifunction inverter heat pump with R290 refrigerant — 6 kW to 19 kW
The FSH HP Master is an air/water multifunction heat pump with inverter compressor, designed for residential installations and running on R290 natural refrigerant. A single outdoor monobloc unit provides heating and cooling, and with a suitable cylinder your domestic hot water too — working with radiators, underfloor heating or fan coils.

Why FSH HP Master
Efficient, quiet, and kind to the planet
A++ efficiency
Seasonal efficiency (SCOP) of up to 4.83 at 35°C flow — roughly 4.8 units of heat for every unit of electricity over a heating season.
R290 natural refrigerant
Propane-based R290 has a global warming potential of just 3 — a fraction of conventional refrigerants — and allows high flow temperatures.
Inverter compressor
Modulates its output to match what the house actually needs instead of switching on and off — steadier temperatures and lower running costs.
Heating and cooling
Reversible — heats in winter and, with fan coils or underfloor circuits, cools in summer from the same unit.
Works with radiators
Rated for 55°C flow (SCOP 3.60 on the 12 kW), so it suits existing radiator systems as well as low-temperature underfloor heating.
Quiet outdoor unit
54 dB(A) on the 6, 9 and 12 kW models — comparable to a quiet conversation — so it sits happily beside the house.

Frequently asked questions
Will a heat pump work with my existing radiators?
Usually, yes. The FSH HP Master is rated for 55°C flow temperatures, which suits most radiator systems, though some homes benefit from upsizing a few radiators. We’ll check this as part of the survey.
Is there an indoor unit?
The FSH HP Master is a monobloc: the whole refrigerant circuit is sealed inside the outdoor unit and only water pipework runs into the house, where it connects to your heating system and hot-water cylinder. That keeps the indoor installation simple.
Which size do I need?
It depends on your home’s heat loss — its size, insulation, glazing and how well it’s sealed — rather than floor area alone. As a rough guide the 6–9 kW units suit well-insulated homes and the 12–19 kW units larger or older houses. We size every installation properly before quoting.
How noisy is it?
The 6, 9 and 12 kW units are rated at 54 dB(A), the 19 kW at 58 dB(A) and the 15 kW at 60 dB(A). For comparison, normal conversation is around 60 dB. Siting the unit sensibly keeps it unobtrusive.
Does it cool the house in summer?
Yes — the unit is reversible and can provide cooling (6.25–15.50 kW depending on model) through fan coils or underfloor circuits designed for it. Standard radiators are not suitable for cooling.
