Hi there,
We are doing a major renovation and extension on our weatherboard cottage in the Dandenong Ranges, which has a tin roof and is raised up on stumps. Once completed the house will be insulated all round, with double glazed windows.
We want to install hydronic radiators but have no gas to the property, so will use a heat pump. The problem we're having is that we've been to multiple suppliers and installers around Melbourne and have been getting grossly different quotes and advice about the size of panels we will require. We're also getting very different advice about the wisdom (or not) of combining our hydronics and domestic H2O using a separate coil tank attached to the heat pump.
We've looked at woodfired hot water and solar already but neither is really feasible for our location and lifestyle.
So am wondering if anyone here has recent experience with installing a heat pump radiator panel hydronics system in Melbourne, and would be willing to share that experience? It's been a very confusing process and it's expensive, so we want to get it right!
Thanks in advance,
Kate
