Hi all, posting this here as I don't want joe blogs putting in his sixpence.
Under floor heating. I'm having a mare with an existing circuit that I've intergrated to the new heating system we just installed.
Apperently (though this can't be proved) it worked before.
Before it was directly plumbed into the old one pipe system, and the only control was a TRV cut into it as it branched off a rad run.
On our new system we have given it a dedicated pumped manifold, thermostat, zone valve, and programmer. The rest of the system (all new) works a treat. The rest of the system (quite big system 37 rads) is zoned and has a main manifold in the boiler room with a pump on each zone. Followed by a one large circulating pump.
The underfloor heating F & R feel warm. The Flow feels a good bit warmer than the return. I powerflushed the underfloor heating before we connected it, and boy was it black.
My hunch, is that the floor which is tiled, might have a very thick screed in which the pipes are buried and there may be no insulation below it. So I'm fighting a losing battle to get it warm. (It was off the whole winter apparently).
That said, on any new UFH we install the floor warms up pretty quickly. I had this on for 3 hours today and the floor temp' didn't change much if at all. Hard to tell as it's a conservatory and the sun warms the floor in places.
I'm up for any ideas, as I'm fresh out, and this is all that stands between me and a much needed final payment!!
Ta,
Danny
