Bathroom Radiator via Hot water Cylinder

[clintpike]

Hi all,
My bathroom radiator is heated via the hot water cylinder - I'm not sure if this is just to heat towels when Heating is off or its for a requirement for the cylinder?

Any ideas?

Reason I ask is because I am removing the wall between the bathroom and toilet to make it all one room but this radiator is on the dividing wall. So need to move it or remove it - there is another radiator in the toilet which maybe could be used instead?

Any info would be appreciated

Thanks

That's a bit like saying 'My car won't start, can you tell me why?'
We can guess at possible pipe layouts, what's feeding the rad etc. but without knowing more details no-one could say for sure.

Old school plumbing. Bathroom rad off the circs to ensure dry warm towels in the summer.

you can remove rad it's in the primary's. Is this a gas or oil install or is it solid fuel? If solid fuel , it's a NO!

not at all uncommon to find a bathroom rad fed off the primaries. as ermintrude says do not under any circumstances remove this radiator if your heating is fed by solid fuel without cutting in another rad elsewhere 'on the primaries' as this is required for heatloss.

Hi all, thanks for replies. It's off a gas boiler.
So if I remove it would I need to connect the inlet and outlet pipe of the radiator together to complete circuit?
If I did use the radiator that's in the toilet instead would that mess up my heating circuit or would that be ok if I just again connected in and out pipes together?
cheers

That would be a heat sink rad would it not? to stop your secondary from getting too hot.

Not on a gas boiler it's not.

Im not talking about gas, im talking about solid fuel. The only reason I could see you needing one on gas is to keep the boiler from locking out after the zone valves shutting down.

OP's system is gas. Solid fuel is another matter. As for locking out the boiler that's probably what the abv is for.

My posts don't show right away, so the op posted back before my post was visible. Yes the auto bypass valve is for that but what if the pipework to the abv was too short to provide a usable flow/return temp difference?

The rad is a relic from old system!

Then the installer wants his backside kicking.

So what would you do if you had your boiler right next to an unvented cylinder?

wrt what?

nice big loop would help

 

[Jimbobber]

Ok but obviously maintaining the abv being the closest back to the boiler on the circuit?

 

[lame plumber]

Boiler right next to unvented cylinder, hence a very short run to the abv. Surely you would need to fit a heat sink rad on the primaries?

someone is getting muddled with when and where heat sinks are required

OK so please enlighten me. I know that they are needed for solid fuel appliances due to lack of thermostatic controls for your stored hot water. When else might we use them then? Cheers!

Re read your text books.

 

[Jimbobber]

I know we don't have any TRV's in rooms with room-stat fitted (ie. hallway normally), but don't remember that being referred to as a heat sink rad.

Only have a level 2 textbook, but thanks for reminding me I really need to purchase a level 3 book and get reading up on it!

If you're removing the radiator and it is in the hot water circuit, just cap off the pipes. Don't connect together unless the radiator is designed as a bypass in the system. I would advise you get a plumber in because if you get it wrong you could have problems later.
