The Daikin Altherma air-to-water

The Daikin Altherma air-to-water heat pump system comprises two components, an outdoor heat absorbing unit (heat pump) and an indoor heat exchanger ‘hydro-box’ unit, connected by refrigerant pipe work.

Altherma incorporates the very latest in inverter and heat exchanger technology, uses the most efficient R-410A non ozone depleting refrigerant and state-of-the-art electronic controls. These technologies are harmonised to achieve the highest recorded operating efficiencies in all weather conditions (down to -15°C) producing water temperatures up to 55°C without supplementary electric heating.

Hydro-Box Indoor Unit

Outdoor Unit

Storage Tank (optional)

The Indoor HB is a compact wall-mounted unit that can be located anywhere in the house. It does not require flues or ventilation. It is connected to the outdoor unit via refrigeration pipework.

The main function of the HB is to transfer the absorbed heat from the outdoor unit to the house heating and hot water system.

The extremely quiet, weatherproofed outdoor unit, can be located up to 30m from the indoor HB.

It contains the heart of the heat pump system, absorbs low grade heat from the ambient air, upgrades it to high grade heat which is transferred via refrigeration pipework to the indoor HB.

A water tank is required for domestic hot water. The stainless steel water tanks are available in 150 litre, 200 litre and 300 litre models, complete with auxiliary heater, sensor and all necessary controls.
