Towel rail too hot!

[damian_taylor]

Hi.
I recently had a towel rail fitted as one of 7 radiators in my new central heating system.
I have a Worcester 24i combi boiler supplying the hot water.

The plumber fitted standard towel rail valves rather than TRVs to the towel rail because he said the towel rail should always be left fully open as a bypass.

The problem is the towel rail gets too hot to touch even if the boiler is on low.
I'm sure I could fix the problem by fitting a TRV but I'm worried I'll break something because of the bypass thing.

Can anybody help me sort this one out?
If a child touches this thing they could get burned it's that hot!!

Thank you very much for your help.
Regards,
Damian

THERMOSTATIC RADIATOR VALVES
If thermostatic radiator valves are to be fitted to the system then
they must conform to the requirements of BS2767:1972. It is advisable
to leave one valve permanently set at maximum to prevent the boiler
short cycling.

Could have a bypass fitted between flow and return enabling this rad to be put on a TRV and curing your problem.
Will involve extra work which = extra cash.

Thanks Bacho!
Does fitting a bypass just mean joining the flow and return immediately before the towel rail with an extra piece of pipe?

I'll get the plumber back to do this if it's as easy as that

Cheers,

might be an idea to fit one of these as well

I believe that new regs state that an automatic bypass must be used where there is not one fitted in the boiler.
Kev will confirm

there is one fitted in the boiler but the mans also recommend a rad left uncontrolled

dont see why it wouldnt be ok

Thanks a lot guys I'll get my plumber to fit a bypass for me at the towel rail and change the valve for a TRV.

Can't be having kids stuck to me towel rail can I!

Do you have all trv's and no roomstat?

An automatic bypass fitted on the return and flow near the boiler would be sufficient and the rads with trvs would be suffecient, it does not need to be at the towel rail.
