Any help.... similar problems anyone has experienced before?

This happened to my screed - around the doors, etc. I was told it was normal and we went ahead with glued wooden flooring. Everything seems fine.

If anything it is too loose but I don't think its that causing it. System been setup for 1.5 years and the radiator hasn't been touched. I have a feeling it might be the rad thermo valve? If I change this would I have to bleed the system, etc?

No - I have been in the property for about 1.5 years so haven't really done anything since it was set up.

Morning everyone, Just wanted to get some tips/thoughts on the below: I have my radiators on a timer to come off every night at 12.45AM. I have 6 radiators in the house. At 12.45 AM one of the radiators in the hallway (a vertical one) makes a bang/loud click noise. Similar to a thermostat but much louder. Initially thought it was the thermostat but can confirm its the radiator. It has been doing this for about 3 or 4 weeks. Every night like clockwork. Has this happened to anyone? Does anyone have any tips or suggestions? Thank you in advance!

I have quinn therm 100mm all over the floor. The house is covered in a silicon based render and has 100mm insulation around. Typical I lose 1 degree over night with heating off so not too bad.

I see. My room stat is set at 25 and I never turn it down 24hrs a day.... I know some will say that's hot but kids feel colder on anything below that... My gas usage for December was £115. That's an actual reading not an estimate.

Thank you very much for your answers! My boiler temp is and has been set at 75. Do you think I should leave it on that or lower it?

hello everyone, First, just wanted to say hello as I am new to the forum. Been reading here a lot recently and look forward to become part of this community ! Bit of background... About 1.5 years ago I moved into my new house that I bought and renovated the year before. Downstairs we put a wet UFH systems and rads upstairs. The ufh pipes are covered by 75 mm of screed and then having engineering wood glued on top. Unfortunately the plumber (who was sub contracted by the builder) proved to be very incompetent. Long story short I kicked him out, etc. After a few different plumbers, we managed to get the underfloor heating working. It has performed very well so far and I am pleasantly surprised by the low gas bills... ONE SLIGHT ISSUE - Sometimes when I come downstairs in the morning I notice that the floor is very hot. I went on amazon and purchased one of those infrared thermometers. It showed 30/31 degrees in some places. I remember hearing that 27 should be the max and so my investigation began... After much googling around I read somewhere that I need to look at the manifold temperature/blending valve. This was set on 55 Degrees. Why? I have no idea that's how the plumbers left it when I first moved in. I have turned this down right down to 37/38 degrees and my floor surface temperature is now 26/27 degrees. My questions: Is this the right way to run UFH? Will I be spending more given the low manifold temperature? Will be boiler be constantly on as my ufh will be keeping the house warm with low manifold temperature? Just want to make sure I haven't done anything to potentially do harm to my system...
