Vaillant heat pump product range
The Vaillant heat pump product range includes the aroTHERM and the flexoTHERM models, with the former being an ASHP (air source heat pump) and the latter operating with multiple sources. For most homes in the UK (2-3 bedroom households), a 12kW heat pump can be appropriate, costing roughly between £6,000 to £11,500.
| Product line | aroTHERM | aroTHERM Plus | aroTHERM Split | flexoTHERM Exclusive |
|---|---|---|---|---|
| Source | Air source | Air to water source / hybrid | Air source | Air, ground, and water source |
| Capacity (kW) | 3.5 - 12 | 3.5 - 12 | 3.5 - 12 | 14 - 46 |
| Efficiency | A+++ | A++/A+++ | A++ | A++/A+++ |
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.
The Plus version adds a water tank allowing it to act as a hybrid or air to water source heat pump. Similarly, the aroTHERM Split has a detached unit that can be placed up to 15 metres away, allowing for different setups and less noise from the unit.
In terms of ground source heat pumps, the Vaillant flexoTHERM Exclusive can use the air, groundwater, or the ground as a heat source. It can also work with water bodies much like water source heat pumps.
The full installation cost for Vaillant heat pump can vary, but heat pump grants are available that can help out. The company’s products are MCS accredited, making them eligible for the Boiler Upgrade Scheme (BUS) which grants £6,000 for heat pumps.
It is worth noting that Vaillant has discontinued geoTHERM heat pumps, making them available only on second-hand markets with no warranty. Vaillant ground-source heat pump prices are very high, so it’s best to buy a model with a warranty.

Advantages of Vaillant heat pumps
- Reduced energy bills: Vaillant heat pumps take up 75% of natural power from the air, water, or ground, which saves you quite a few pennies.
- Quiet operation: Vaillant heat pumps are considered the quietest on the market, with some models like the flexoTHERM ground-source heat pump being as quiet as a coffee percolator even when transferring heat.
- Government incentives: According to “The Boiler Upgrade Scheme,” homeowners in England and Wales are eligible for heat pump installation grants – up to £6,000 for GSHP and £5,000 for ASHP.
- High efficiency: Vaillant heat pumps have a Coefficient of Performance (COP) of up to 5.2, making them exceptionally efficient, which also allows for a lower carbon output. This allows for £290 in annual savings.
- Remote control: Vaillant comes with an app-based heating control system vSMARTᵀᴹ allowing heat pump owners to control heating anytime and anywhere. You can also access holiday functions and maintenance indications like low water pressure or any other faults.
- Hybrid options: Vaillant offers a range of heat pump options, including hybrid heating systems that combine an air-source heat pump with a boiler. Such shared workload contributes to the Vaillant products’ life and boosts their energy efficiency by automatically switching between the boiler and the pump, especially when outside temperatures are colder.
- Durable lifespan: With proper maintenance, Vaillant heat pump solutions can last up to 25 years. This is especially handy since heat pumps break even in 16 years, allowing for optimal savings from that point on.
- UK headquarters: Vaillant UK has a heat pump factory in Belper, Derbyshire and can suggest heat pump installers all over the country for delivery and installation.
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.
- High upfront costs: Installing a heat pump system is more expensive than traditional heating systems despite their cost-effectiveness in the long run. Buying and installing a Vaillant heat pump might cost between £3,000 and £15,000 depending on the system type, property size, and project complexity.

Vaillant air source heat pumps per house size
Vaillant heat pumps come in a variety of sizes, each of which is appropriate for different homes. An 8kW heat pump will be best for a single-bedroom home, while 12kW systems can be best for 2-to-3 bedroom homes. For homes with 4-bedrooms and more a 16kW system is the best.
For this reason, the Vaillant flexoTHERM will be more appropriate for larger homes (4-bedroom+) while the aroTHERM can be ideal for 2-to-3 bed houses or smaller, with the exact size depending on the heat pump’s output.
| Household Size | Min. Heat Pump Output Size | Estimated Supply Cost | Estimated Installation Cost | Estimated Total Cost |
|---|---|---|---|---|
| 1 bedroom | 8kW | £4,000 - £8,400 | £350 - £1,700 | £4,350 - £8,700 |
| 2-3 bedrooms | 12kW | £6,000 - £9,800 | £350 - £1,700 | £6,350 - £11,500 |
| 4+ bedrooms | 16kW | £8,000 - £12,350 | £350 - £1,700 | £8,350 - £14,050 |
Comparatively, the prices are quite competitive with top brands. There are multiple brands that offer lower prices but may not manage the features, such as a 7-year warranty.

Should I get a Vaillant heat pump?
When choosing a heat pump, Vaillant can be a great choice. Vaillant air source heat pump models can be fairly competitive with many top brands. Despite competing with quite a few cheaper models, they can be worth the price since they offer a warranty of up to 7 years, A+++ efficiency, and allows for quiet but effective temperature control.
It may not be ideal if your home often experiences temperatures under -20°C. Since this doesn’t apply to a lot of UK homes, there is a high chance you can do fine with Vaillant systems.
