How does Altherma work?

How does Altherma work?


At the heart of the Daikin Altherma system lies the air-to-water heat pump. The heat pump is today's answer to current and future concerns with conventional heating systems (such as rising energy costs and a high environmental impact).


Daikin's Altherma utilises free heat from the ambient air to maintain ideal comfort conditions via a refrigerant transfer cycle that delivers this heat into your home. This is an efficient process for transferring heat energy as it only requires 1 kilowatt of electricity to pump 3 to 5 kilowatts of heat into your home (in other words, 66_80% of the heat energy produced by Altherma comes from the outside air and is free of charge).


To make this happen, there's an outdoor unit and an indoor unit. Circulating between the outdoor unit and the indoor unit is a refrigerant that absorbs heat energy from the ambient air and releases that heat energy into the indoor unit. A secondary heat exchange then occurs within the indoor unit as the heat absorbed is transferred from the refrigerant circuit to the water in the system and then sent through the underfloor distribution network to heat your home.
