HEAT. DIFFERENTLY.
YOUR HOME.
NOT A COMPROMISE.
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.
ONE RANGE / FIVE SIZES
ONE RANGE.
FIVE OUTPUTS.
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.
THE DETAIL.
WHEN YOU NEED IT.
One model selection. Every technical view. Verified figures where we have them; a clear next step where we do not.

—kWRated heating output
Explore rated heating capacity at the outdoor and flow temperatures actually present in the approved data. Select a point to read its exact value.
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.

80°C test data does not redefine the published maximum flow-temperature specification. Installers must consult HISA before system design.
