This is my first winter in Carwoola. I had a new heat pump hot water system installed replacing a 30-year-old electric HWS. The installer recommended installing in the same location 2 metres from the house with all pipes leading to the house and from the water tank underground.
Since we have recently had some big frosts – I find I get no hot water till the sun comes out. The installer keeps telling me that they can do nothing about it – apart from putting some lagging around the copper – which they originally did, but not much of.
Even with some lagging, I still have the same issue.
Can anyone tell me if pipes can freeze underground? Is it worth getting some sort of insulating cover for the HWS? Am I wrong to think that when you get a quote to buy and install a HWS that they should use local knowledge to know whether it was a good idea or not to install the type of HWS and location.
Very expensive big water tank if I cant get this resolved.
Any tips welcome.
