t depends on the projects and usage of the heat pump. For under floor heating or low temperature radiator, the normal setting is 25°C/35°C.Under this small delta T condition, CO2 heat pump can also work with very high COP, its efficiency is similar with the conventional heat pump like R32 or R290. F
The R744 heat pump heats water instantly, which means it can rise up the inlet water into setting temperature at one time circulation, it offers fast and stable hot water. You don’t need to wait more time to reheat after the cylinder is empty and refilled.
