Underfloor heating not working :(

[Susie221]

I have Gedhill stainless Lite cylinder, it's been in two years
the underfloor heating worked ok in the living room and kitchen and one bedroom, the others we didn't even put on as we didn't need it, I have just had ceramic tiles put over the whole of the flat, and then only the living room was working, now that's stopped working as well ! What should I be looking at ? For ?
Last week the boiler was making a lot of sound and it's since then that the living room hasn't worked properly
Help

What's the heating system pressure?

 

[efficiencyman]

Control zone valves, Solenoids, check thermostats for all zones, timer, control fuses, has someone damaged stat sensor wires, Air vents, ?
The system needs checking out by a professional on site to do full system checks

What's the heating system pressure?

Where do I look ? It's a warmafloor system
everything is hot pipes etc but no heating in floor, have hot water

I'd be asking the tiler!

I'd be asking the tiler!

I wouldn't want to tile the floor whilst the U-F heating was on..

No but it worked before he started?

Like already mentioned you defo need an engineer as it could be a number of things. The system maybe hasn't been properly vented at the start and sounds like the manifold actuators need looking at or it maybe the thermostat that controls the actuators . You can also put an add in this forum to see if you can get one of the good guys to have a look. At least that way you will get your system up to the standard it shouldve been from the start.

I bet the tiler turned off the flow restrictor on the rooms to be tiled.

I bet the tiler turned off the flow restrictor on the rooms to be tiled.

The heating wasn't on when the tiler was working, I mean all thermostats in the rooms were switched to off position
and the heating didn't come on before he did the job ( we only used the living room as that was the only room that needed it) and it worked ok after tiling as well ?

Possibly a pump fault?
