Viessmann Heat Pumps Brand Page

Viessmann primarily offers air-to-water heat pumps (which extract heat from the outside air) and ground source heat pumps (which extract heat from the ground). They also have commercial and larger-scale solutions. For residential use, popular series include the Vitocal 150-A, Vitocal 151-A, and Vitocal 200-A (all air source). They also offer ground source models like the Vitocal 200-G.

Yes, Viessmann heat pumps are known for their high efficiency. Many models achieve an A+++ ErP rating and have high Seasonal Coefficients of Performance (SCOP) and Coefficients of Performance (COP), often up to 5.0 or higher. This means they can produce 3-5 units of heat for every 1 unit of electricity consumed.

Yes, many Viessmann air source heat pumps, particularly the Vitocal 150-A and 151-A, can achieve flow temperatures of up to 70°C. This often means they can be integrated with existing radiator systems without needing extensive radiator upgrades, especially if the property is well-insulated.

Yes, many Viessmann air-to-water heat pumps offer a reversible function, meaning they can provide both heating in winter and active cooling in summer.

Viessmann invests in Advanced Acoustic Design (AAD) to ensure low noise levels. Some models, such as the Vitocal 200-A, can operate as quietly as 35 dB(A) at 3 meters. Even larger units aim for minimal disturbance, often around 49-53 dB(A) at the unit, which drops significantly with distance.

Yes, Viessmann heat pumps are eligible for government grants like the Boiler Upgrade Scheme (BUS) in England and Wales (£7,500). Other schemes may be available in Scotland (Home Energy Scotland Grant and Loan) and Wales (Nest Scheme).

Standard warranties are typically 2 years. However, if installed by a Viessmann Trained Installer and registered within 30 days, the warranty can often be extended to 5 or even 7 years (sometimes with a chargeable upgrade for the longer period).

Yes, Viessmann heat pumps are designed to integrate well with renewable energy sources like photovoltaic (PV) solar panels. This allows you to use self-generated electricity to power the heat pump, further reducing running costs and carbon emissions.
