Vaillant Heat Pumps: Costs, Reviews and More (2023)
Given the existing incentives and policies, there is an anticipation of significant growth in the UK heat pump market. The industry is striving to align with the UK’s Net Zero objective of installing 600,000 heat pumps annually by 2028.
Vaillant heat pump solutions play an essential role in this strategy. In fact, according to a 2023 YouGov poll, Vaillant is the UK’s 4th most popular energy and utility brand.
Vaillant is a leading heat pump manufacturer using natural energy sources like air, ground, or water to generate heating and hot water for homes and buildings.
In this piece, we will walk through the Vaillant heat pump lines and compare the prices as well as dig into some reviews to help you find a ground-source, air-source, or water-source heat pump.
Yet, it’s worth noting that even if you’re sure about a specific heat pump brand, your search for a heat pump won’t end there. Next, you’ll need to find certified installers in your area which is not always a piece of cake.

Vaillant heat pump costs
Vaillant heat pumps’ cost varies depending on the model, capacity, and installation costs. With a new Vaillant heat pump, you’ll be looking at a price between £3,000 and £15,000, not including the unit’s installation.
It is hard to evaluate the Vaillant heat pump cost since the final result is affected by additional variables such as the size of the house, the homeowner’s budget, and the overall energy consumption that is connected to the desired warmth level.
| System type | Air-source | Ground-source | Water-source |
|---|---|---|---|
| Product line | aroTHERM | geoTHERM mini flexoTHERM Exclusive | flexoTHERM Exclusive |
| Capacity (kW) | 3.5, 5, 7, 10, 12 | 22, 30, 38, 46 | 5, 8, 11, 14, 19 |
| Efficiency | A++ | A++ | A++/A+++ |
| Sound power (dB) | 53–60 | 54-61 | 41–50 |
| Max. heating temp. (°C) | 63 | 62 | 65 |
| Warranty | Up to 7 years | Up to 10 years | Up to 10 years |
| Price (without installation costs) | £3,000–£15,000 | £8,000–£11,000 | £4,000–£9,000 |
Unlike other types, ground-source heat pumps have generally higher fitting costs due to the installation being more complex and requiring more additional materials. So it’s advisable to look for grants and quotes that will help you save costs on your project.
Vaillant heat pumps are available in ground-, water-, and air-source models. Currently, Vaillant is the only manufacturer that also offers hybrid heat pump solutions allowing you to use both renewable and traditional heating sources like boilers.
Ground-source heat pumps extract heat from the ground to produce domestic hot water or heat the building. Ground heat is a reliable and stable energy source due to the GSHP environment being underground.
The temperature underground remains stable at approximately 12⁰C regardless of climate fluctuations, providing a dependable and consistent energy source for ground-source heat pumps, which allows them to maintain their efficiency levels unaffected.
The flexoTHERM Exclusive and geoTHERM mini product lines represent Vaillant ground-source heat pumps.
The flexoTHERM Exclusive heat pump is equipped with an integrated EVI (Enhanced Vapor Injection) super compressor that injects additional refrigerant into the compression cycle, resulting in enhanced performance and energy efficiency. The flexoTHERM heat pump operates at noise levels as low as a modern refrigerator of 42dB(A), making it a quiet and unobtrusive heating solution.
It has received the ‘Quiet Mark’ approval, excluding the 230V range. The heat pump incorporates Green iQ technology, which not only ensures optimal efficiency and performance but also aids in future-proofing the product.
The flexoTHERM Exclusive heat pump can be cascaded with up to seven units, making it suitable for larger domestic and commercial properties. This feature allows for increased heating capacity and flexibility.
The geoTHERM mini is the UK’s first wall-hung ground source heat pump designed to extract energy from various sources such as communal ground arrays, boreholes, water boreholes, rivers, lakes, or streams, utilising sustainable renewable energy.
The decentralised design of the geoTHERM mini enables individual property metering, allowing homeowners to have greater control over their energy usage and only pay for the energy they consume.
The geoTHERM mini is MCS accredited, which may qualify for government incentives like the Boiler Upgrade Scheme (BUS). With this scheme, you can get a £6,000 ground-source heat pump grant which significantly reduces the overall cost.
It is worth noting, though, that Vaillant has discontinued geoTHERM heat pumps, making them available only on second-hand markets with no warranty.
The Vaillant ground-source heat pump prices vary depending on the preferred voltage and output.
We understand how easy it is to get lost in dozens of heat pump models available in the market. Finding a suitable heat pump solution takes hours of your time you could have spent with your family instead. And looking for a certified and trusted heat pump installer isn’t something you want to spend your precious weekend on.

Air-source heat pumps source heat from the ambient air, which is then transferred to a refrigerant that increases its temperature to heat the inside of a building or provide hot water for domestic use. Only a small amount of energy is required to run the system in order to ensure reduced running costs.
Vaillant air-source heat pumps are represented by the aroTHERM line which offers various output sizes – 5, 8, 11, and 15kW. It is recommended to have a well-insulated home for optimal performance, with a heat loss calculation by a Vaillant Advance Renewable Installer determining the most suitable model.
Converting to an air-to-water heat pump system typically takes 3 to 5 days. The aroTHERM is also certified by the Microgeneration Certification Scheme (MCS), making it eligible for a £5,000 air-source heat pump grant from Boiler Upgrade Scheme. The Vaillant air-source heat pump prices depend on the property size and output power so such a grand might be quite handy.
Water-source heat pumps work by moving heat from one medium where it’s readily available to another medium that can accept it. The medium donating the heat is called the “source,” while the one receiving the heat is called the “sink.” Water-source heat pumps are a perfect heating or cooling choice if you live next to a lake or a river.
Vaillant flexoTHERM Exclusive can use the air, groundwater, or the ground as a heat source. Therefore, it can be connected to either a ground collector or borehole system to provide efficient generation of heating and hot water.
The full installation cost will vary, and heat pump grants are available to help. However, if you’re still unsure whether a Vaillant heat pump is for you, weigh up their products’ pros and cons in the next section.

Together with that, the following factors might come out as disadvantages for some homeowners.
Disadvantages of Vaillant heat pumps
- Discontinuation. Some Vaillant heat pump models like geoTHERM are only available on second-hand markets with no warranty as they have been discontinued.
- Space requirements. Heat pumps require a lot of space for an outdoor unit and piping and indoor space for a hot water cylinder which might not suit smaller properties.
