In producing heat and hot water and choosing the right size of heat pump, be aware of your domestic hot water demand and heat receivers.
Lower demands can be met with 180-liter heat pumps with an integrated water heater plus the option of a second tank for more demand. 55-60 °C is sufficient. A heat pump heats radiators and wet floors regardless of the required supply temperature. However, if the heating supply line is lower than consumption, less energy will be needed, providing MAX efficiency.
