We do not fear from the cold
Sweden definetly is a country with a cold climate. By the beginning of 2009 in Sweden are mounted around 700,000 heat pumps .
Each third heat pump sold in Europe in 2008 was air-to- water. The heat pumps air - water are suitable for use both in countries with mild climates such as southern France and in countries with harsh climates such as Germany , Austria, Switzerland , Norway, Finland.
The use of air in the cold climates, as a source of heat, at first glance does not look at - the reasonable solution.
If you actually do a careful analysis of (COP) coefficients , the resulting from testing of modern heat pumps air - water, we can see how highly efficient and reliable heat pumps are, even in areas with a harsh climate . High-tech manufacturing and efficiency of facilities ensure their high efficiency and rapid return on investment.
