This real‑world Hungarian installation demonstrates our scalable R290 air‑to‑water heat pump solution for large‑size non‑residential buildings. Four 16 kW units run in cascade configuration to deliver reliable space heating for a two‑storey, 3000 m² training institution, with one extra 9 kW unit dedicated fully to domestic hot‑water supply.
Using natural propane R290 refrigerant with near‑zero GWP, this multi‑unit system meets strict European environmental requirements. The cascade setup enables flexible load adjustment: it automatically activates or idles individual units according to real‑time heating demand, optimizing energy efficiency and lowering operational costs throughout cold Hungarian winters.
All outdoor units are firmly mounted on vibration‑dampened bases to keep noise levels under control for the surrounding premises. This turn‑key commercial heating case proves our R290 heat pumps are well‑suited for schools, training centres and other large public facilities. If you are planning a medium‑to‑large heating renovation project across Europe, get in touch for a custom‑tailored proposal.
