Vaillant heat pump will pave the way for a sustainable future

Vaillant has expanded its portfolio of renewable technologies with a new heat pump system, the aroTHERM plus. The heat pump has been developed in-house using the natural refrigerant R290, which helps Vaillant, its installers and users to prepare for a sustainable future.

R290 is a natural refrigerant with a low Global Warming Potential of 3. Its use fulfills the next nearly zero-energy buildings (NZEB) requirements and, with an ErP rating of A+++, the aroTHERM plus is one of the greenest heat pumps on the market.

Greater comfort levels can also be achieved with R290 as it enables aroTHERM plus to run at a higher flow temperature of up to 75°C, providing 25 per cent more useable hot water and removing the need for an electric immersion heater for the Legionella cycle.

It’s energy efficient too: in testing, aroTHERM plus has seen up to a 43 per cent saving when replacing oil or LPG heaters in retrofit projects. It is also quiet, with sound as low as 54dB.

Launching alongside the aroTHERM plus is a new indoor unit, uniTOWER. Containing an integrated hot water cylinder and hydraulic components, it is pre-wired for fast and easy installation. With no refrigerant certification required, connecting both the aroTHERM plus and uniTOWER modules can be completed in a single day.

John Bailey, head of commercial & renewable systems, says: “We are delighted to add the aroTHERM plus air source heat pump to our portfolio in 2020. It is an important time for the UK heating market, the pressure is on to find a range of renewable solutions that can effectively and efficiently heat our homes and help the nation decarbonise in the years ahead.”

aroTHERM plus will launch in Q3 2020.
