Well that sounds like a win, hopefully. Nothing else to ask I dont think (other than the installer password if there is one - which is probably the d...
OK so feed to rads colder than feed to UFH and colder than flow temp from heat pump. Not good, losing efficiency and thus oomph to building. Taking ...
It does feel like you may have a genuine fault, unfortunately perhaps not bad enough to convince the manufacturer easily. Id be tempted to collect ...
