Viessmann heat pump models
Viessmann offers a vast range of air source and ground source heat pumps suitable for various household needs. When breaking down the different models, it is important to be aware of the key terms used in the product description of Viessmann heat pumps:
- Coefficient of Performance (COP): This shows how well a heat pump works. It is done by comparing how much heat it moves vs how much energy it uses.
- Heating output: This shows the amount of heat that is produced that enters your home.
- Domestic hot water cylinder (DHW): A cylinder that comes with some heat pumps that store your hot water, which means you get hot water for your taps, showers, and baths.
- Flowing temperature: This is the temperature of the water that flows from the heat pump into your heating system (like radiators or underfloor pipes).
- Cooling function: This is the ability of a heat pump to take heat out of your home, making your house cooler in hotter months.
Below, we have broken down their models for air source and ground source heat pumps.
