HISA R290
High-temperature R290 air source heat pumps designed around simple installation, efficient operation and long-term HISA support.
HISA R290 / AIR SOURCE HEAT PUMPSHEAT. DIFFERENTLY.
An existing home should not have to start again. HISA R290 brings high-temperature heat to radiators and underfloor heating — with system design matched to the home, not the other way round.
CONSIDERED FOR LIFE AT HOME
Comfort inside. Consideration outside.
HISA R290 Gen2 air source heat pumps are designed for quiet residential operation — bringing heating performance to your home with consideration for your garden and the neighbours beyond it.

HISA HR290-008-1PH · ErP · Average climate · W35°C
Approved single-fan family imagery. Decorative rings illustrate the design theme, not measured sound propagation.
Sound levels vary by model and operating condition. The figure shown is sound power under the stated ErP W35°C / average-climate condition — not sound pressure at 1 metre. Actual sound heard around a home depends on siting, surroundings and operation; suitable installation remains important.

ONE RANGE / FIVE SIZES
Start with a model. Let a heat-loss calculation decide the size. The numbers identify output classes, not a promise of capacity at every temperature.
FOR THE HOMEOWNER. FOR THE INSTALLER.
One model selection. Every technical view. Verified figures where we have them; a clear next step where we do not.
Explore rated heating capacity and COP at the outdoor and flow temperatures actually present in the approved data. Select a point to read its verified results.
Explore rated heating capacity and COP at the outdoor and flow temperatures actually present in the approved data. Select a point to read its verified results.
COP is the coefficient of performance at the selected operating condition. It is dimensionless, is not SCOP and is not a general or seasonal efficiency claim. COP is shown to two decimal places; source precision is retained in the underlying data.
Each marked point is a verified source value. Connecting lines are visual aids, not tested intermediate values. No interpolation or extrapolation. Not every temperature combination is available.
Source: HISA Gen 2.0 performance data. Heating capacity and COP from the same rated operating point.
80°C test data does not redefine the published maximum flow-temperature specification. Installers must consult HISA before system design.
