Vaillant Heat Pumps

As a name synonymous with manufacturing quality heating products, Vaillant have launched their aroTHERM plus range of air to water heat pumps.

Vaillant heat pumps are a reliable and efficient way to heat your home. The aroTHERM plus range of air to water heat pumps from Vaillant is designed to provide an economical and eco-friendly solution for heating your home.

These heat pumps use the ambient air temperature outside to extract energy, which is then used to heat water inside your home. This process is more efficient than a traditional boiler.

Using a natural refrigerant in R290, this gives a low Global Warming Potential (GWP) rating of only 3. When you consider that other heat pumps on the market using refrigerants such as R410a which has a GWP of 2,088, it is clear that the aroTHERM plus range is much kinder to our planet.

There are a number of other features with the aroTHERM plus range such as the flow temperature can reach up to 75°C. This helps with the production of hot water without the need for an immersion heater for protection against legionella, making the system more efficient.

As this is a range of monobloc units, there is no F-Gas requirement meaning that installation can be carried out by a plumbing and heating contractor with hydraulic and boiler installation experience.

Vaillant also have a range of hot water cylinders to compliment the operation of the aroTHERM plus heat pump and together with a range of accessories available through Unitherm a full system package is supplied.

Extended warranties are available through Unitherm, please contact us to discuss.
