Altecnic: How to Install an Anti-Freeze Valve

As heat pumps use a refrigerant to absorb the heat from the air, ground, or water, they have a risk of freezing. This is particularly so when installed in places that are exposed to the elements and fluctuations in temperature. Should freezing occur, not only would any repair be costly, it could cause further issues for the heating system and reducing its efficiency.Fitting an ‘Anti-Freeze Valve’ is the best method of preventing a heat pump from freezing.
