Changing bathroom radiator

womble12345

I have changed radiators before and it was just a case of draining the system, changing the radiator and refilling the system. I want to change the radiator in my bathroom, this one is different as it comes on with the hot water rather than the central heating. How do I go about disconnecting this radiator without flooding the house?
Thanks

Remove the valves from the radiator in the closed position, in other words leave the valves on the end of the copper pipe.

And start by closeing the stop tap if it's not a sealed system.

I should have said, I want to change the valves as well so really need to make sure I don't flood the house.

You will need to drain the domestic hot water system.

Is that just a case of draining the hot water tank?

The rad will be connected to the hot water flow side of the system.no need to drain any of the hot water tank,just drain the heating system down low enough to prevent flooding when removing valves

by the flow side do you mean between the boiler and tank?

Ermmm... am I missing something here? Is everyone saying that the hot water contained in the cylinder is what heats the towel rad??


If so - ummm... best go back to college peeps

So Ruski what are you saying heats my radiator?

Ruski

The same water that heats your cylinder.... unless it's a heat sink rad? What's the setup? Do you have a motorised valve and pumped system?

It is just a normal radiator with normal valves on each end. I do have a motorised valve and and a pump in the system.
