Ideal logic combi 30 boiler drainage????

[leonieadam]

I have a Ideal Logic Combi 30 + boiler but I need to drain the whole system due to a leak that requires the heating system pipes empty but just trying to find out if its at all possible to drain the system from the boiler instead of draining via a radiator??

Thanks Adam

There should be a drain point on your pipe work some where a lot easier . Connect a hose or if you haven't use the boiler drain point depending if the leak is higher then the boiler you should be ok

The problem is the boiler is higher than the radiator. The system is old and was installed with the boiler in the kitchen and the pipes running out going upstairs to an airing cupboard into a boiler mate. This has now been removed but it does mean the pipes still going from the boiler upstairs and then split off to come back downstairs to the radiators. I see there is a drain valve on the front pipes of the boiler but If I try drain from here I take it, it wont drain the down stairs radiators (which is where the problem is) due to the pipes to downstairs coming from upstairs

If you haven't got a drain point by the radiator then your only way would be from the bleed valve on the radiator . Good luck

If you need to work on a point lower than the drain valve on the boiler, then you'll have to drain from somewhere else lower than the place in which you need to work. You may have to remove a radiator and drain from the rad valve.

Us Plumbers may be a higher power, but alas, even we cannot change the laws of psychics (unless we carry a wet vac 😉 ). Our battle with gravity and its effects on liquid is a constant one.

lol thanks for the replys. will have to drain from the drain valve. On this type of boiler how will I refill the water back into the system after it has been drained????

You should have a filling loop fitted somewhere which is a flexi hose with two isolation valves either end. Sometimes the hose gets removed and put to one side. Reconnect hose and open isolation valves slowly topping up system to around 1- 1.5 bar.

the hose is still connected in a loop, there is 2 sets of valves on each side 1 set in blue 1 set in black, do i open both of the valves on both sides??

 

[leonieadam]

and will the pressure stay 0 until the whole system is full and then once full start to increase the bar??

My advice would be to leave the boiler well alone, as its pretty obvious you have little understanding of how the very basics work. You will damage your boiler in the long run by trying to make this repair yourself. A qualified plumber would probably not charge you very much and have it done much faster, and safer.

If you've got a suspended floor downstairs and the pipes run under the floor just cut the pipe then pop a hep coupling on after....
dont do this if you live in a first or higher floor flat....

Stop, think about it and make a plan. DO NOT OPEN THE BOILER!!! this can be solved easily and quickly by a heating engineer. or if you think you can, then please feel free to have a go from the lowest point you can. If in a house, just cut the pipes in the crawl space, then make good.
