Why Choose a Vaillant Air Source Heat Pump?

Save Money on Running Costs

All air source heat pumps use renewable energy to generate up to 75% of your home’s heating and hot water needs and, although they use a small amount of electricity to run, they mostly rely on the energy found in the air outside, even when it’s freezing cold. That means a Vaillant air source heat pump provides a greener and more energy-efficient way of heating your home and can help to reduce your energy bills. 

Reduce Your Household’s Carbon Footprint

As previously mentioned, a Vaillant air source heat pump transfers energy from the outside air into your home. If you switch from a traditional heating system to an air source heat pump, you can significantly reduce your carbon emissions and therefore cut your household’s carbon footprint and environmental impact. 

Receive Payments with the RHI Scheme

The Renewable Heat Incentive (RHI) scheme is a government financial incentive to encourage the use of renewable heat to reduce carbon emissions in the UK. If you get a Vaillant air source heat pump installed and qualify for the scheme, you can receive regular payments based on the amount of renewable heat your system generates. The installation must be carried out by an MCS accredited installer, and how much you can earn depends on the age and size of your property and the heating system you choose. You should know that the RHI closes to new applications in March 2022.  

Quiet Mark Approved

Vaillant air source heat pumps have been certified by Quiet Mark, meaning they’re incredibly quiet during operation and can therefore be installed practically anywhere without annoying you or your neighbours. Quiet Mark encourages manufacturers to reduce sound levels in their products and identifies the quietest solutions in a given category to help consumers make informed purchasing decisions. 

Vaillant Air Source Heat Pump Reviews

On the Trustpilot site, Vaillant has an ‘Excellent’ rating based on nearly 16,000 reviews. The majority of the reviews on there have been left by customers who purchased a boiler, but you can find plenty of positive air source heat pump reviews on the site too. 

Please note that the above Trustpilot score is correct at the time of writing in November 2021.
