UFH - Does this look right?

[brownjoe]

Hi All
recently had UFH installed in my house. Having a few problems as the system won't go above 22 degrees and at best feels luke warm. Standard porcelain tiles were fitted above the system in the pic.


Any ideas why this won't work properly?

Thanks

It should have been covered during other works.
However it looks as the spacing is OK although unsupported on the edges.
I'am unable to see what insulation was done prior to laying the cables or where the floor sensor has been placed in the system.
On a normal insulated wooden floor when you switch on electric UFH it would register at about 18degrees before any power is used!
If you are only getting a 22 degree heat then I'd check the position of the sensor to see if it has not been pulled back through the conduit and away from the heat wires and thus not registering an accurate reading, however if it's only 22 then the system may not be receiving any power (ie a fault in the wiring).
Get the part 'p' qualified electrician back who connected it and check for resistance and continuity in the cables.
Still don't like the thought of people working over an unprotected mat - usually causes problems.

I'm not sure there was an additional insulation - which is a worry. there was a hardboard floor put down - which is what the wire was laid on to.

i'm not good with the icon thing - but i'm guessing you guys are saying that's not good?

the programmer may be controlling this 22 degree setting , some new programmers pick up the ambient room temp and will hold the setting at what ever it has been set to . read the programmer instructions .it may be that you have to set it to work from therm probe only..

Is it hardboard indeed Joe?

Could do with more info & photos please of the prepared substrate & materials used.

Have you been in contact with the installers?

I would be sorting the hardboard floor before anything else, that is sure to cause failure when it's tiled..

Wire spacing is a bit wide .surely its not fixed direct to hardboard
