Immergas Audax hydronic heat pumps are made in Europe and include models with 5.8, 7.2, 11.9 and 15.0 kW heating output. These models can also reverse cycle for summer cooling with capacity 7.0, 7.8, 13.5 and 16.0 kW respectively.

Immergas hydronic heat pumps extract heat from the air and transfer it to the circulating water. In winter, they find sufficient heat in the outside air, even if it is below zero. In summer, you can reverse the cycle and remove heat from inside of your house to the outside.

Hydronic cooling works best with chilled water through fan coil convectors. You can also use area cooling with cool water above the dew point with underfloor circuits. Area cooling works best when combined with ceiling fans.

Immergas uses inverter technology for the Audax heat pump range. This allows soft starting and variable compressor speed for optimal efficiency and longer life. They are ideal as stand-alone systems or can be combined with additional heat sources such as a fireplace wetback system.

Immergas Audax hydronic heat pumps are very reliable and come with excellent warranties.

Run your Immergas Audax hydronic heat pump system during the day with your solar power. This will give you low cost solar hydronic heating. Your winter heating or summer cooling will be absorbed by the internal thermal mass of your house then released into the evening.

Read more about thermal mass.

Choose your horizontal buffer tank designed for outdoor installation underneath the heat pump. Alternately, slide it under a suspended floor or other location for best fit. Oversize your buffer tank for greater thermal mass.

Choose a 75 litre buffer tank or larger from the range available: Immergas Buffer Tanks

To work well, a house in a southern or cold inland climate should be thermally efficient with a Star rating of at least 6. It is best to have plenty of thermal mass within the building envelope such as a concrete slab.

There are a range of room climate controllers available including the intelligent Nest controller. Interface the controller with your electronic devices.
