Water source heat pumps (WSHP) are a lot less common than ground source or air source heat pumps, but they are much more effective due to the stability of the heat extractable from a water source. The major disadvantage is that the building where the heat pump is to be installed needs to be in close proximity to a large water source for the heat pump to operate effectively. Let’s look at what water source heat pumps are, as well as the different types of system that are available, the costs involved in installing and running one, as well as how big a body of water
