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, a global pioneer in intelligent climate and energy solutions.
Vitocal 250-A Pro
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°C and DHW 35°C).
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.
compact and stylish
And, due to its maximum flow temperature of 70°C, it can be used with existing radiator systems
It is also remarkably stylish. Its compact, linear appearance, which has already earned it a prestigious iF Gold Design Award, makes it easy to blend into surrounding architecture and landscaping.
And, due to its maximum flow temperature of 70°C, it can be used with existing radiator systems in many cases, making it ideal for larger modernization projects.
Super Silent Design
Installation is faster thanks to factory-installed operating and safety devices, while the feature-rich weather-compensated remote monitoring and control system means 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) by the ErP Directive.
Environmental credentials
“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 several 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.”
Vitocal 250-A Pro
Requiring a three-phase electrical supply, its 40 kW output is sufficient for very large, detached houses
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.
In 2025, the facility to cascade up to four units together will be added, further extending its range of applications.
Fully integrated package
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.
