Hall heating up too quickly & thermostat cutting out

Could be a matter of your radiators being incorrectly sized or the system balancing incorrect. In a balanced system (in an ideal world) all of your radiators should heat up (and shed heat) at the same rate at the same time. It may be a simple matter of checking the balancing. A better flow to your living room could be obtained by opening the lockshield valves on your living room rads. Was the system rebalanced after the boiler change? It should have been.

Actually that was a point that I brought up with the engineers that the radiator was too big for the size of the hall. The radiator is the same size as the ones in the bedrooms which I thought was a bit strange as in the other bungalows I have been in the hall radiators are usually of a smaller size. Answer to that was that the hall would be too cold.

I honestly could not say if the system was rebalanced.

I really do think if I could get the hall problem solved then the rest of the heating would be okay.

THats fine just make sure you leave one of the others on instead, perhaps the bathroom you like the bathroom warm when you come out of the shower.

I had thought about the bathroom one being left on all the time but the problem is that it is a small double radiator in there and the heat is unbelievable. I had to replace the old radiator due to it being badly rusted and when the engineer removed it we discovered there was no tiling behind it so opted for a double panel as it hid the view of seeing down the back of a single radiator to the area where there were no tiles - hope that makes sense.

Silly question but if it is a double radiator and the TRV was set half way would there be enough flow through that as if it was an open single radiator. Probably clutching at straws here LOL!!

Good idea about covering the radiator with a blanket, that might solve the problem in the meantime.

Gosh I try to save money by having a new boiler installed and now my hall overheats and heating running longer, typical!

I would like to say thanks to everyone that is helping solve this problem, it is really appreciated.

The TRV shuts the radiator off completly when its reached its temp setting.

You are best off shutting the hallway one down a bit and leaving another one oon, is there any others that are able to be left on all the time instead?

NO! If it is a TRV, even if it is set to middle position, it does NOT mean half flow. It means that at half temperature, the valve will transit from full flow to no flow. The idea is to have 1 rad on so that then boiler always has a flow through it.

:rotfl:Thought it was a silly question I'd asked. I understand that one radiator has to be left open but was ever hopeful:rotfl:

The only other one that could be left open is the living room as it could do with a bit more heat.

Next question, prior to trying, if the radiator in the living room is set at No 5 does that mean the top temp of that radiator would reach 25+ if the hall thermostat is set at max. If that was the case then I take it that it would be far too hot so might be best going with option of blanket over the hall radiator and eventually, during summer months getting a smaller radiator fitted.

In answer to another post, the heating dial on the boiler is set just under the 5th dot on the dial. I think it goes up to 7 dots.

Simplest solution is to leave the living room door open Then the heat from the hall gets into the living room and the cool from the living room keeps the thermostat turned on.

Just had a brainwave:rotfl:the double radiator in the hall is inside the bathroom directly opposite the hall thermostat. I am wondering if I shut off the hall radiator by quite a bit and opened up the bathroom radiator full and left the bathroom door open slightly do you think that would help? My logic in this is that the bathroom radiator would then more or less be heating both the hall and the bathroom.

As long as you leave one radiator in the lounge on max then you can turn down the one in the hallway, as I said right at the beginning just do this and then set your thermostat on the wall to max so the heating is running this means it isnt overrulled by the temp in the hall.

It really is as simple as that, that way you dont need to put a smaller radiator in and is the money saving expert choice!!!
