Viessmann Launches Future-Proofed Air Source Heat Pump for Light Commercial Applications

TELFORD, UK, September 20th, 2024 Viessmann Climate Solutions UK has launched a new 40 kW air source heat pump that offers unparalleled performance and sustainability for larger properties, public sector applications and small- to mid-scale commercial installations. Viessmann Climate Solutions is a part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions.

Providing both heating and cooling within a single appliance, the Vitocal 250-A Pro has an impressive Coefficient of Performance (CoP) of 5.32 at A7/W35 (outside air temperature 7 oC and DHW 35 oC).  

Unusually for a heat pump of this size, it is energy rated A+++ for both low and medium temperature applications. Equally uncommonly, it uses the climate-friendly natural propane refrigerant R-290, which has a global warming potential (GWP) of 0.02, compared to 1.0 for CO2 and 675 for R-32.

It is also remarkably stylish. Its compact, linear appearance, which has already earnt it a prestigious iF Gold Design Award, makes it easy to blend into surrounding architecture and landscaping. And, thanks to its maximum flow temperature of 70 oC, it can be used with existing radiator systems in many cases, making it ideal for larger modernisation projects.  

Installation is faster thanks to factory-installed operating and safety devices, while the feature-rich weather-compensated remote monitoring and control system mean operation and maintenance are also greatly simplified.

Viessmann’s Super Silent  Design incorporating vibration decoupling and sound jacketing ensures the Vitocal 250-A Pro is very quiet in operation; at A7/W35, the total sound power level is 58.0 dB(A) in accordance with the ErP Directive.  

“The 250-A Pro stands out because of its looks, its performance and its environmental credentials,” said Viessmann Product Manager, Hugh Jones. “This is a premium heat pump that fills a gap in the market for a highly efficient, propane solution for larger installations. We have a number of customers lined up who have been waiting for an appliance that can offer this level of quality and efficiency at the scale and price point they need.”

The Vitocal 250-A Pro can be operated in bi- or monovalent modes. Requiring a three-phase electrical supply, its 40 kW output is sufficient for very large, detached houses or apartment buildings with four to five flats. Next year, the facility to cascade up to four units together will be added, further extending its range of applications.  

The launch of the Vitocal 250-A Pro means installers can offer a fully integrated package of high-quality, future-proofed HVAC, power-generating and system-management products from Viessmann that are designed to work together seamlessly at scale. Free training courses are available through the Viessmann Academy.
