Daikin Altherma High Temperature Heat Pump

In older or harder to heat properties, you need a system that reliably delivers higher water flow temperatures of up to 80ºC, without necessarily replacing the whole radiator system

System elements

1. Outdoor unit

The outdoor unit extracts heat from the outside air and transfers it to the indoor unit via refrigerant piping.

2. Indoor unit

The indoor unit can be sited up to 50 metres away from the outdoor unit.

3. Unvented domestic hot water cylinder

The unvented domestic hot water cylinder can be stacked on top of the indoor unit, thus saving space.

4. Solar system

The HT heat pump can be connected to a solar thermal system for higher hot water efficiencies. A dedicated unpressurised thermal store works together with the drainback solar system and floor standing hydrobox.


For boiler replacement and retrofit projects:

The Daikin Altherma high temperature system is ideal for straight-forward boiler replacement. The system offers:

 Superior and unique cascade heat pump technology

 Water flow temperature of up to 80°C, without need for an electric back-up heater

Hot water recovery time as fast as a boiler

 Modular design and easy to install as all of the components are pre assembled.


Keep your existing radiators

Choose a high temperature or bivalent system (which uses an existing boiler, combined with a heat pump) and you don’t even need to change your existing radiators, so installation is even easier. This makes the Altherma high temperature heat pump the market leader for retro fit systems for older properties or where it is not practicle to change the existing radiators.


Combine with under floor heating or radiators.

Daikin Altherma offers highly efficient split and monobloc air source heat pump solutions, which are ideal if you have under floor heating, low temperature radiators or even your existing radiators. The Altherma range offer a complete solution for your home. This advanced technology in the use of ozone friendly refridgerants enables you to have complete control over your heating and hot water therefore only using the energy which is required to keep your home comfortable, whatever the temperature is outside.
