Air Source Heat Pumps
Viessmann Vitocal Heat Pumps
Air source heat pumps serve as a great alternative to conventional heating systems, as they enable you to generate your own heat and could help you to reduce both your energy bills and your carbon footprint. But what exactly are they and why should you choose one? Scroll down to read more and shop for Viessmann’s air source heat pumps.
Why choose an air source heat pump?
Thanks to the highly efficient design and the system’s efficiency, these solutions can generate heat even when the temperature outside is as low as -15°C. This dispels the myth that heat pumps are only effective in warmer climates and they can continue to gather warmth even when temperatures drop at night.
As well as providing heat during the colder months, air source heat pumps can serve as cooling systems during the summer, too. With an air source heat pump cooling system, you’ll benefit from a versatile solution that can help you to enjoy comfort at home throughout the year, and not just in winter.
