Description

The Vaillant aroTHERM Plus 5kW R290 Heat Pump is a compact, ultra-efficient and future-ready air source heat pump unit, designed for smaller to medium-sized homes and low-energy properties. This air-to-water heat pump works by absorbing heat from the outside air and efficiently transferring it indoors to heat your home and hot water, even in cold weather. Combining outstanding efficiency with whisper-quiet operation, this space-saving Vaillant aroTHERM Plus unit delivers reliable heating and hot water while significantly reducing environmental impact.

Using the natural R290 refrigerant that features an ultra-low Global Warming Potential (GWP) of just 3, the aroTHERM plus is one of the most sustainable heat pumps available today. Despite its compact size, it delivers impressive flow temperatures up to 75°C, making it fully compatible with traditional radiator systems and hot water production without needing an electric immersion heater - even during pasteurisation cycles.

Certified by Quiet Mark, the aroTHERM Plus operates at only 54 dB(A), ensuring minimal noise impact in residential areas. Built with future-proof technology and high-temperature capability, it offers homeowners both comfort and peace of mind while meeting tomorrow’s environmental standards today.

Designed to work seamlessly with Vaillant’s indoor range, including the uniTOWER (0010037212), hydraulic module (0010037207), and heat pump interface (0010037212). The system is highly adaptable for new builds and retrofit installations alike.
