Built for hotel-scale hot water demand
Full occupancy, back-to-back checkouts and a kitchen running at the same time — hotel hot water has to keep up. Orca systems are proven to cut water heating costs by up to 70%, scaled from a handful of rooms to a full hotel.
Sized to the property, not the other way around
Most hot water systems get chosen to fit a budget, and guests are left to work around it — showers running lukewarm during a busy changeover, or a boiler labouring to keep up with a full house. An Orca system is specified the other way round: sanitary hot water capacity is sized to your occupancy, not the reverse, with sanitary tanks scaling from 500 litres up to 5,000 litres.
Because Orca heat pumps operate independently down to −7°C, and as low as −15°C with the integrated electric heater, output stays dependable through a January cold snap as well as a busy August bank holiday weekend. Every unit stores water in a stainless steel boiler, so what comes out of the tap stays clean as well as hot.
Running costs stay low throughout: an average Coefficient of Performance (COP) of 3.6 means 3.6kW of heat for every 1kW of electricity used, and most hotel installations pay for themselves within three years.

Why hotels choose Orca
Independent, year-round heating
Many heat pumps stop working around 7°C outside air temperature. Orca keeps going alone to −7°C, and as low as −15°C with the electric heater assisting — so a cold snap is never the reason a guest gets a lukewarm shower.
Clean, healthy water
Water is stored in a stainless steel boiler rather than a standard cylinder, which matters when a single tank is serving dozens of rooms and bathrooms.
Heat and cool at once
Cool air is a byproduct of heating water with an Orca system — useful for cooling a food store or plant room at the same time, with no extra equipment needed.
