Viessmann Climate Solutions UK has launched a new 40 kW air source heat pump designed for larger properties, public sector applications and small- to mid-scale commercial installations.
Providing both heating and cooling within a single appliance, the Vitocal 250-A Pro has a Coefficient of Performance (CoP) of 5.32 at A7/W35 (outside air temperature 7°C and DHW 35°C).
It is energy rated A+++ for both low and medium temperature applications and uses the 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.
The company says that thanks to its maximum flow temperature of 70°C, it can be used with existing radiator systems in many cases, making it suitable for larger modernisation projects.
The new Air Source Heat Pump features factory-installed operating and safety devices, along with a weather-compensated remote monitoring and control system designed to ensure operation and maintenance are also greatly simplified.
“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 and requires a three-phase electrical supply. The company says that next year, the facility to cascade up to four units together will be added, to further extend its range of applications.
