I need to disconnect a jaga strada radiator for decorating. How can I disconnect without draining the system?

It is a two pipe connection to the floor with a deco thermostatic head

Thanks

    Hello,

    For decorating purposes you can simply remove the casing, you can do this by firstly opening the TRV head to 5 then unscrewing it from the valve (depending on the type of head, there may be a black collar which you will have to undo first), then lift the casing off and over the TRV pin. This will then simply leave the element and brackets on the wall.

    There should have been a white cap that was screwed on to the valve when first supplied, you can screw this back on to close the valve off.

    If you are not removing the actual heating element or brackets then you shouldn't have to worry too much about the heating system, simply replace the casing and TRV head once all the decorating has been done.

    Kind regards.

    Hi,
    You don't neccesairly need to disconnect the radiator at all. The casing ca be removed with relative ease.
    1. Turn TRV head up to highest setting.
    2. remove TRV head (by undoing chromed nut)
    3. Slide casing towards the valve end as far as it will go
    4. Remove retaining bar from the back of the grille
    5. Remove top grille
    6. Lift casing (approx 10mm) and tilt it forward
    7. Lower casing to release from bottom of bracket
    8. Casing should now be free to be removed over the pin of the valve
    Steps 6 to 8 can be a bit a bit of a fiddle.
    Full fitting instructions can be found her:

    This will now expose the elements and brackets that can be decorated around, and the casing can be re-fitted in the reverse order of the above.

    If you want to take the elements and the brackets of the wall as well, you can isolate the one valve by re-fitting the TRV head and turning down to the frost setting. This will isolate the flow connection. You will also neeed to isolate th return which can be done by closing the lockshield valve. Depending on the exact valve type depends on how this is done. If it is a Jaga valve there will be a chrome cap that can removed, and then a 5 or 6mm allen key hole. This is the return valve. When closing it please make a note of the number of turns required to fully close as this will need to be opened the same amount.
    Once both valves are closed you can remove the blanking plug from the spare connection to drain the heat exchanger. You will need to put a bowl under the radiator to catch the water.
    The heat exchanger can now be disconnected from the valve by undoing the unions between the valves and the heat exchanger.
    The heat exchanger and brackets can be removed as a complete sub assembly

    Hope this helps
