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 ...
All understood. Basically you are planning on creating a recirculating loop. There are a couple of threads running about this with people complaini...
The last bit of that is bad. Thats just badly (well appallingly) designed UFH and most likely the fundamental problem here - half your energy is goin...

OK. I have 2.8 for DHW and 3.4 for space heating running at an actual FT of about 36. Yours does seem a bit low depending on what FT you were runnin...
Don't forget to increase max ft also. Mine is set to 55, way clear of the curve. I think that might even have been the default.
