Towel radiator too hot

techguy81

Recently moved house and have come to use the central heating now the temps are dropping.

There are TRVs on all radiators throughout the house except for a towel radiator in a small shower room. This presumably doubles as a means of heating the room, however it gets very hot and it is uncomfortable to use the shower whilst the central heating is switched on.

There are two what I believe to be lockshield valves on the towel radiator. I have read it might be possible to adjust one of these (outgoing valve?) to reduce the flow of water passing through, and therefore lowering the output temp. However I am concerned about this having an affect on other radiators. I also believe there should be one radiator permanently fully open, which is probably the one I want to alter!

Any suggestions?

Thanks

You can try turning the lock shield valve down, you can turn completely off and then turn back about 1 turn, it probably won't affect the temperature of the rad though it will just take a bit longer to heat up. The other option is turn down the boiler stat tho this could obviously affect other rads.

Perhaps you could have a TRV fitted and remove one from a more suitable radiator?

The reason it has lockshield valves and not a TRV is for safety, if there isn't a built in by-pass in the system and it sounds like there isn't, at least 1 rad/rail has to be unable to shut it'self down on temp. Normal practice is for this to be the bathroom to aid drying, the more "suitable" radiator in most cases.

Yes, you simply throttle 1 of the LSV down until the rail runs at the desired temp, and yes, it will push water elsewhere, you then shut the hottest 1 or open the coldest 1 until you have a "balanced system"
Every home owner has to do this at sometime or other, just make all adjustments at LSV end.

Thanks for the input everybody.

I'm tempted to try scottishblondie's suggestion of fitting a TRV and nominating another rad to be the "always on".

We have our "always on" radiator in the hall.

We have a very large hall with a big open tread staircase, so it never gets too hot.

Above the radiator we have fitted a row of coat hooks, so, when the heating is on, wet coats get dried, and you get a nice warm coat to put on in the morning

typically you'd expect to find the always on in the same room (hall) as the thermostat.

I'm sorry but absolutely not, that's the last place you want it as it will continue to allow the rad to run and shut the house system down when the rest is calling, you really should have thought that through before posting.

Coldest or wettest room is the norm, that could include the hall, but not if the stat is in the hall

Our system is an old one, we don't have a thermostat. But it works fine with the TRVs and the boiler stat.

When we need to replace the boiler, we will need to get a thermostat. I plan to get a wireless one and experiment with the best position.
