Viessmann has developed a warmth pump for residential purposes that may produce 5.8 kW to 10.4 kW of warmth. It has a capability to warmth 220 liters of home water, with a coefficient of efficiency (COP) of as much as 4.8 for area heating and three.14 for water heating.
Germany-based heating specialist Viessmann has launched a brand new line of ground-source warmth pumps for residential purposes. They’re particularly appropriate for indifferent homes and new buildings.
Vitocal 222-G is available in three variations, with heating outputw between 5.8 kW and 10.4 kW, and a COP as much as 4.8.

They’ve an built-in hot-water cylinder, with a capability to warmth 220 liters of home sizzling water at a COP of three.14. They will present sizzling water to the home at a most temperature of 58 C. The minimal temperature of the bottom supply is -10 C and the utmost is 25 C.
The bottom-source warmth pump measures 680 mm x 600 mm x 2,000 mm. The 5.8 kW gadget weighs 277 kg and the ten.4 kW one weighs 28 kg. They use R410A refrigerant with a worldwide warming potential (GWP) of 1,924.
“The casing of the compact equipment utterly protects the refrigeration module/hydraulic compartment from the exterior setting and, mixed with three-dimensional anti-vibration mounts, reduces working noise,” Viessmann claims on the product’s web site. The warmth pump produces a noise of 46 dBA, which is decrease than the noise of the fridge.
