The Vaillant aroTHERM Plus air source heat pump is a natural refrigerant, renewable technology heating solution
Air source heat pumps are an increasingly popular choice for homeowners who are looking to install renewable energy solutions.
The main advantage of air source heat pumps and boilers is that they safeguard homeowners against fluctuations in energy prices. Heat pumps use the environment to generate 75% of the heating and hot water needs for your home, meaning that you’re significantly less reliant on electricity to keep your home toasty, and you’re much less vulnerable to the ever-rising costs of heating in your home.
