We've had wet under floor heating in our kitchen diner for about 6 years now, and apart from a couple of minor problems I've not had to touch it for a few years, so today i thought I would look inside the cabinet where the manifold etc lives, ( I know, i live an exciting life ), lol.
Anyway, just want to check that all the settings seem right, flow temp is set at 50 degrees, pump speed is on 2, and the system pressure is just under 1 bar, should the pressure be slightly higher?
Is the pressure directly related to your boiler pressure ?
I'm literally about to change a pump on our UFH, four manifold system for a building, runs at 6 bar from memory, as this is the pressure for the closed water heating system.
1-1.5bar should be ok.
There is approx .5 bar difference between the boiler gauge and ufh manifold pressure gauge, I've just increased it slightly to see what happens, boiler is running 1.7 and manifold is reading 1.2 bar.
I should add that the UFH is currently calling for heat so the boiler is running.
I’ve found ours to be more effective with the pump speed on 1
When you say, "more effective", in what way, heats the floor up quicker?Originally Posted by bootneck
