Many thanks - that is a saving, but still seems pretty high! Has anyone found inexpensive solutions to exterior insulation where there is the ability ...
Any recommendations on reasonably priced exterior insulation or alternate methods to insulate - e.g. boxing in the exterior pipes and using something ...
@skd I think the pump will raise the LWT temp to the setting for the maximum heat pump flow temperature. I increased that to 60C and during the legion...
