Vaillant aroTHERM Plus 7kW – Latest Generation R290 Monobloc Heat Pump
Key Features
- Ultra‑quiet operation from just 46.2 dB(A)
- High efficiency with ErP ratings up to A+++
- 75°C flow temperature – ideal for radiator systems and retrofits
- Natural R290 refrigerant with extremely low GWP of 3
- Compatible with uniTOWER, hydraulic modules and uniSTOR cylinders
- Smart‑grid ready (SG‑ready) and PV‑compatible
The Vaillant aroTHERM Plus 7kW is a high‑output, low‑noise air‑to‑water heat pump designed for medium‑sized homes and retrofit applications. Using natural R290 refrigerant, it delivers excellent efficiency, ultra‑low environmental impact, and high flow temperatures suitable for properties with existing radiators or higher hot water demand.
Its compact monobloc design simplifies installation and removes the need for F‑Gas handling. With very low noise levels, the 7kW model is easy to site in semi‑detached homes, detached properties, and noise‑sensitive areas.
The aroTHERM Plus integrates seamlessly with Vaillant controls such as sensoCOMFORT and sensoAPP, and pairs perfectly with uniSTOR heat pump cylinders for a complete, high‑performance system.
High Performance
The 7kW model delivers strong output even in colder conditions, with flow temperatures up to 75°C. This makes it suitable for radiator‑based systems, hybrid setups, and properties requiring higher domestic hot water temperatures. Legionella protection is achieved without immersion heaters, improving efficiency and reducing running costs.
Energy Efficiency
With a SCOP of around 3.62-4.98 (system and site dependent), the aroTHERM Plus 7kW offers excellent seasonal performance. It is PV‑ready and SG‑ready, enabling integration with smart tariffs and solar PV systems to maximise self‑consumption and reduce operating costs.
Ultra‑Quiet Operation
The 7kW unit features Vaillant’s advanced acoustic engineering, achieving sound power levels as low as 46.2 dB(A). Noise‑reduction modes make planning and siting straightforward, even where boundary distances are tight or neighbouring properties are close.
Natural Refrigerant (R290)
The sealed monobloc system uses R290 natural refrigerant, delivering a GWP of just 3. This ensures long‑term compliance with future environmental regulations and offers reduced protection zones for easier siting and installation flexibility.
