When replacing an existing heating system with the Daikin Altherma High Temperature, radiators do not need to be replaced. Daikin Altherma High Temperature replaces your conventional boiler and perfectly supports existing high temperature radiators with water temperatures up to 80°C if required.

This system is similar to the split system by using an outdoor unit to extract heat from the outdoor air. This heat is transferred to the indoor unit via refrigerant piping to the indoor unit. The indoor unit further increases the temperature, allowing water temperatures up to 80°C for heating through radiators and for domestic hot water use.

Daikin’s unique cascade compressor approach to the heat pumps (one in the outdoor unit/one in the indoor  unit) means optimum comfort at even the coldest outdoor temperatures, without the need for an electric back up heater.
