Bathroom rad with no TRV does not appear to be working at all
Yes pressurised, They are fully filled, works fine on the rad with 15mm pipes its the 10mm piped rads that are the issue, installers just left, they've forced through as much as they can, glycol is at -10 degrees efficiency, rads heat has moved up the rads a bit more. We're testing it over the weekend. If it doesn't work they'll drain the system and put dump valves on as we know it works with just water (mitsubishi are happy with them doing that, doesn't invalidate warranty etc)
