Products Features
Wide Running Range
Thanks to Inverter EVI technology, All-in-one Air to Water Heat Pump features a wide operating temperature range for house heating, cooling and domestic hot water. It means it can reach high water temp. even in cold climate, and can work safely and reliably at ambient temperature as low as -35℃.



R32 Refrigerant
Compared to the refrigerants widely used today, such as R-22 and R-410A, R32 has a global warming potential that is two-third lower and it is remarkable for its low environmental impact, which helps to speed up its popularity in the industry,the pursuit of every detail is the guarantee of your family.



FAQ:
Q:How do air source heat pumps work?
A:Air Source Heat Pumps, similar to a refrigerator, work on the principle of condensation and evaporation to extract heat from the outside air of your home.
Essentially, this means that they reverse the normal state of thermal energy, moving it in the opposite direction of normal heat flow by extracting the heat from a cold location and releasing it to a warmer one. In a way, they make the indoors warmer by making the outside colder.
There are two major types of air source heat pumps: air-to-water and air-to-air systems:
Air-to-water systems
Heat the water in your wet central heating system e.g. through your radiators, underfloor heating and hot water storage cylinders.
Air-to-air systems
Heat the property with fans that can also provide cooling–like air conditioning, ideal for the warmer months of the year. For this reason, heat pumps are usually described as air conditioners that can work in reverse.
