Was ist R290?
R290 is propane used as a refrigerant in heat-pump systems. It has very low global warming potential compared with many legacy refrigerants, but it is classified as highly flammable, so system design, installation and applicable safety requirements matter.
Wo können R290-Wärmepumpen eingesetzt werden?
Air-to-water R290 heat pumps can be used for space heating and domestic hot water in residential and commercial applications, subject to system design, climate, temperature requirements and local regulations.
Was sollten Käufer vergleichen?
Compare heating capacity at defined outdoor and water temperatures, leaving-water temperature, efficiency data, acoustic performance, operating limits, electrical requirements, controls, hydraulic configuration and service support.
Die Systemauslegung ist entscheidend
The heat pump is only one part of the installation. Emitters, buffer volume, hot-water storage, hydraulics, controls and commissioning affect real-world performance.
