Air source heat pump positioning is one of the most common questions I get asked when homeowners are looking at specify this renewable technology. 

There is a common train of thought that the outdoor unit should be placed on the south side of the property where it will benefit from the heat from the sun. However, there are a lot of variables to consider when siting an air source heat pump and unfortunately in the greater scheme of things the sun is only a very small one.
