R290 – high-purity propane suitable for refrigeration applications – is steadily gaining ground in modern heat pumps. The reason is clear: it offers a very low environmental footprint and can support efficient operation even at high water temperatures. However, R290 remains a Class A3 flammable refrigerant, which poses a particular
