Vaillant Heat Pumps and Renewable Heating Products

Formed in Germany in 1874, Vaillant is a leading manufacturer in the heating industry. The company offers multiple forms of residential and commercial energy products, including renewable energy solutions. These include a range of heat pumps and hot water cylinders.

Below is a selection of Vaillant products relevant to heat-pump systems. Suitability and output must be confirmed through a property-specific heat-loss calculation and system design.

Known for their quality, reliability, and high-efficiency, Vaillant heat pumps are hugely popular among Essex homeowners. The company offers a vast selection of heat pumps, including ground, water, and air source options. Each different model caters for different-sized homes with different energy needs.

Some energy suppliers offer heat-pump tariffs, but rates, eligibility and available products change. Compare the current tariff terms with the expected system demand rather than assuming a fixed running cost.

The aroTHERM plus is a highlight in Vaillant’s heat pump portfolio. It uses R290, a natural refrigerant, which helps to achieve higher flow temperatures of up to 75°C. While keeping temperatures high, the aroTHERM plus keeps noise low. Its Sound Safe System keeps noise to a minimum of 54dB, making it ideal for use in built-up residential areas.

aroTHERM Plus 7kW highlights:

• Height: 965 mm

• Width: 1100 mm

• Depth: 450 mm

• Weight: 128 kg

• Flow temperature: 75°C

• Minimum noise: 54dB

• Operating temperatures: -25°C to 40°C

Pros and cons:

Pros:

• Smaller size, perfect for fitting into smaller spaces

• Cheaper alternative to higher-end models

• Excellent construction quality and durability

Cons:

• Noisier than other Vaillant models

• Lower operating temperatures

The 5kW aroTHERM plus is one output option within the current aroTHERM plus range. Model selection should follow the property heat-loss calculation, required flow temperature, hot-water design, electrical supply and proposed outdoor-unit location.

aroTHERM Plus 5kW highlights:

• Height: 765 mm

• Width: 1100 mm

• Depth: 490 mm including the back plate and mounting brackets

• Weight: 114 kg ready for operation

• Flow temperature: Up to 75°C, subject to operating conditions

• Minimum noise: Check the current Vaillant acoustic data for the selected model and design conditions

• Operating temperatures: Check the current Vaillant operating envelope for the selected model

Pros and cons:

Pros:

• Incredibly versatile system, suitable for most homes

• Lower installation costs than most air source heat pumps

Cons:

• Needs space indoors and outdoors for both units

• Lower flow temperature than other Vaillant models

Vaillant offers more than just heat pumps, with a selection of other products in its portfolio. These include hot water cylinders, which are compatible with Vaillant heat pumps.

Vaillant’s uniSTOR heat pump cylinders are designed to work in tandem with the company’s heat pumps. They help your heat pump to work with added efficiency, while also reducing running costs. With special insulation and vacuum panels, the cylinders optimise heat transfer and store hot water. This takes away the need to heat water on demand, reducing electricity usage.

Pre plumbed cylinder:

• 200 litre

• 250 litre

• 300 litre

uniSTOR slimline pre-plumbed cylinder:

• 150 litre

uniSTOR standard cylinder:

• 150 litre

• 200 litre

• 250 litre

• 300 litre

uniSTOR large capacity cylinder:

• 500 litre

• 800 litre

It’s easy to control multi-zone heating systems with Vaillant’s sensoCOMFORT device. With the press of a touch-activated button, you can change the temperature of rooms in an instant. The device also contains an outdoor sensor, which provides an understanding of the thermal behaviour around your home. It will then adjust flow temperatures to ensure maximum efficiency.

Nominal model output is not a substitute for design. Published capacity, efficiency and sound figures are measured under stated conditions and can change as outdoor temperature and required water temperature change.

• Compare output at the project design temperature.

• Check capacity and efficiency at the intended flow temperature.

• Confirm acoustic calculations for the proposed location.

• Include the cylinder, controls, emitters and electrical requirements.

• Use the latest manufacturer data for the exact model reference.
