Viessmann ground source heat pumps

Viessmann have added to their industry leading range of boilers with a wide selection of ground source heat pumps. Viessmann ground source heat pumps are the ideal option to help transition your home towards a low carbon future.

When comparing ground source heat pumps – or any heating system – it’s important to consider the output rating, efficiency, warranty and, of course, potential cost.

  • Output: The power of the heat pump is measured in kilowatts (kW) and known as the output rating. Larger properties with a high demand for central heating will need a heat pump with a larger output rating. Your installer will be able to recommend a suitable output rating able to meet the needs of your home.
  •  

  • Efficiency: The efficiency of a heat pump relates to how much heat it’s able to produce from the electricity needed to power it. Ground source heat pumps are highly efficient and capable of delivering efficiencies of 300% to 500%. So, for every kWh (kilowatt-hour) of electricity that’s 3 to 5 kW of heat.

    When comparing ground source heat pump efficiency, look out of the Coefficient of Performance (CoP). The CoP shows how much heat you’ll be getting per kilowatt hour of electricity. And in the case of Viessmann ground source heat pumps this ranges from 4.1 to 6.6.

  •  

  • Warranty: During a warranty period, you’ll be able to rely on the manufacturer to resolve any issues with the heat pump that you may experience. What’s covered will be highlighted within their own terms and conditions so check them thoroughly before committing. Viessmann ground source heat pumps are available with a warranty of 5-7 years.
  •  

  • Price: Ground source heat pumps are one of the more expensive heating systems available. In addition to the cost of the unit itself, you’ll also need to factor in the installation. Which, for a ground source heat pump, can be anywhere between £3,000 and £30,000.
     
    As well as the initial costs, it’s important to also consider the long term savings. The savings being made on your heating bills could actually see you make a return on your initial investment. Plus, the return could happen even sooner with payments through the Renewable Heat Incentive (RHI).

Viessmann ground source heat pumps largely operate as brine/water which means that they absorb geothermal heat. The Vitocal 300-G and Vitocal 350-G ranges can be converted to water/water ground source heat pumps which take heat from ground water.

Viessmann Vitocal 200-G heat pumps

Ideal for installation in new build and semi-detached properties, the Viessmann Vitocal 200-G range is efficient, quiet and simple to install.

Vitocal 200-G Models Output Rating (kW) Coefficient of Performance (CoP) – Central Heating Maximum Flow Temperature
BWC 201.A06 5.6 4.1 60°C
BWC 201.A08 7.5 4.4 60°C
BWC 201.A10 9.7 4.3 60°C

Viessmann Vitocal 222-G heat pumps

Vitocal 222-G heat pumps are available in outputs of 5.8 kW up to 10.4 kW and can provide domestic hot water as well as central heating. They’re suitable for installation within detached homes to meet a domestic hot water cylinder capacity of up to 220 litres.

Vitocal 222-G Models Output Rating (kW) Coefficient of Performance (CoP) – Central Heating Maximum Flow Temperature
BWT 221.B06 5.8 4.6 65°C
BWT 221.B08 7.4 4.6 65°C
BWT 221.B10 10.4 4.8 65°C

Viessmann Vitocal 300-G heat pumps

On their own, Vitocal 300-G heat pumps are a perfect match for detached homes. Alternatively, 2 units can be paired together to meet higher heating demands in residential buildings. Once installed, these are highly efficient heat pumps that are solar-compatible which will help to lower running costs.

The below models are brine/water which means they absorb geothermal energy from the ground.

Vitocal 300-G Models (Brine/Water) Output Rating (kW) Coefficient of Performance (CoP) – Central Heating Maximum Flow Temperature
BW/BWC/BWS 301.B06 5.7 4.6 65°C
BW/BWC/BWS 301.B08 7.6 4.7 65°C
BW/BWC/BWS 301.B10 10.4 5.0 65°C
BW/BWC/BWS 301.B13 13.0 5.0 65°C
BW/BWC/BWS 301.B17 17.2 4.7 65°C

Below are the water/water Vitocal 300-G heat pumps which can deliver higher efficiencies.

Vitocal 300-G Models (Water/Water) Output Rating (kW) Coefficient of Performance (CoP) – Central Heating Maximum Flow Temperature
BW/BWC/BWS 301.B06 7.5 6.1 65°C
