Compare Vaillant Ground Source Heat Pumps
Well known for their efficient and reliable boilers, Vaillant also manufactures a range of renewable heating systems. Vaillant ground source heat pumps are available in a range
Comparing ground source heat pumps to find the right one for your home means looking at the output rating, efficiency, warranty and, of course, the price.
- Output rating: A ground source heat pump's power is measured in kilowatts (kW). It's important to install a heat pump with an output rating that matches the heating demands of your home. Otherwise, if it's too low, it will fail to meet demand and if it's too high then your energy bills could end up soaring. A professional heat pump installer will be able to recommend the most suitable output for your home.
- Efficiency: Heat pumps need electricity for power and how much heat they generate from the electricity is shown as the efficiency. You can see how efficient a heat pump is by looking at the Seasonal Coefficient of Performance (SCoP). Vaillant heat pumps have a SCoP of between 4.4 and 5.1 (at 35C) which means a kWh of electricity is converted into 4 to 5 times as much heat.
- Warranty: After the installation of a heat pump, you'll be covered by a manufacturer warranty. This means that in the unlikely event of an issue, the manufacturer will seek to repair it.
All warranties vary in terms of length and what's covered during that time so make sure to check the terms and conditions.
- Price: The upfront costs of a ground source heat pump and the installation are much higher than a conventional boiler. However, they can last twice as long as boilers and could help to lower your heating bills. Plus, RHI payments can potentially see you make a return on that investment.
Vaillant ground source heat pumps are efficient, reliable and quiet heating systems available in a range of outputs to suit the heating demands of different homes.
