Vaillant aroTHERM Plus 10kW – Latest Generation R290 Monobloc Heat Pump
Key Features
- Ultra‑quiet operation from approx. 50 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 10kW is a high‑capacity, low‑noise air‑to‑water heat pump designed for medium to large homes, retrofit radiator systems, and properties with higher heat loss. Using natural R290 refrigerant, it delivers excellent efficiency, ultra‑low environmental impact, and high flow temperatures suitable for demanding heating and hot water requirements.
Its compact monobloc design simplifies installation and removes the need for F‑Gas handling. With low acoustic output for its size, the 10kW model is suitable for detached homes, larger semi‑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 10kW model provides 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 typically in the 3.86–5.12 range (system and site dependent), the aroTHERM Plus 10kW offers excellent seasonal performance for larger properties. 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
Despite its higher output, the 10kW unit maintains low acoustic levels, with sound power around 50 dB(A). Noise‑reduction modes make planning and siting easier, especially 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.
