Germany’s Vaillant has developed an air-source warmth pump that makes use of propane (R290) as a refrigerant. It may possibly produce between 3.4 kW and eight kW of warmth, and home scorching water to a temperature of as much as 75 C. It says that the warmth pump can save when paired with rooftop photo voltaic.
Vaillant joins Bosch and Mitsubishi in releasing an air-source warmth pump that makes use of R290 as refrigerant.
The Germany-based warmth pump producer mentioned its new warmth pump is designed for renovation installations and new buildings.
“Our new aroTHERM plus air-to-water hat pump can be utilized in retrofit installations as a result of it may well attain excessive circulate temperatures,” mentioned Vaillant on its web site. “Even methods with radiators, which require circulate temperatures as much as 55 C, might be operated effectively.”
It has a heating capability of three.4 kW and eight kW, dimensions between 765 mm x 1,100 mm x 450 mm and 1,565 mm x 1,100 mm x 450 mm, and a weight of 114 kg, 128 kg, or 210 kg, relying on the variant. The coefficient of efficiency (COP) varies between 3.9 and 4.6 when heating water to 35 C, with outdoors air to 2 C, and between 5.3 and 5.7 with outdoors air at 10 C.
The pumps are supposed to provide scorching water between 22 C and 75 C. The brand new gadgets might be put in indoors or outdoor, however the 190-liter water tank have to be put in indoors .
“The acquisition prices are additionally comparatively low, as aroTHERM plus is likely one of the cheaper warmth pumps in the marketplace,” in response to Valliant.
It’s mentioned that financial savings might be maximized by pairing the warmth pump with rooftop PV. Additionally it is famous that the noise degree ranges from 54 dB(A) to 59 dB(A) through the day and 46 dB(A) within the night time mode – nearly equal to the sound of a fridge.
“When the aroTHERM plus is positioned three meters away, the sound stress degree is 29 dB(A), which is equal to the ticking of a watch,” says Valliant.
