Hydrogen gas in radiator

[regdennis]

Can anyone suggest a product that will get rid of hydrogen gas in a central heating system. It has been flushed out and has twicw the normal ammount of inhibitor in the system ... but every other day one radiator is cold and full of hydrogen gas ... everything has been tried to solve the problem and any suggestions would be welcome

when the husband bled the rads, was he not filling up baloons for the local kids without the wife knowing

think on the positive side regdennis,
if she has the farts at her age, at least she can blame it on you or her rads to her visitors.

Is it an open vented system, could be a simple case that the pump is set to high & drawing in air.

'Matches'.....whatever next! Surely a 'lighter' is the way forward.

lighters are dangerous as they can explode, use a flint

went on a powerflushing course and thats what the man told us to do! is the system old with leaking pipework ? could try and seal it

 

[regdennis]

Hilarious many thanks for all the funny remarks *** !!

To me if it needs bleeding every two days then there is probably a water leak somewhere in the system. Is there an expansion vessel in the boiler? If so, this is probably at fault (or needing to have some air put into it.)

it will prob be an old open vented system, remember H&S, catch the gas in a bag and take it outside before you try to light it, is that me on the binned list as well?

I did enjoy reading through this thread! But lets be serious Reg, in a very old system where is hydrogen gas going to be produced? Any fluxes left in quantities enough to cause gassing to the degree and for as long as you describe,would have eaten through the pipes and caused leaks long before now. If you only changed the header tank it seems unlikely anything you did is contributing. Far more likely air is being drawn in some point and the problem rad is the first in line after it. Is the water boiling in the boiler?
If on the other hand it is hydrogen look for wires connected to the rad and make sure there are no mad professors in the basement!

thought it was a bi product of corrosion, therefore could happen in any system

If there is hydrogen in the radiators. It could be due to corrosion in the rads. It can be due to flux from a new installation entering the system. It can be due to the system pulling in air . Or bacteria in the water. If it's in a hard water area and the boiler is aluminium the stuff you get in the kettle causes blockage in the system. You need to empty the system. If the water is red its corrosion new rads needed. If it's black sludge its flux needs cleaning. If it's clear water it it need the right inhibitors. And the pressure sorting out on the boiler it may be drawing in air. First empty the system see what comes out. If black sludge or red water comes out its a chemical problem where thE metals corrosion or flux mix together causing gases in water. That's why cleaning joints is important when pluming.
If they have been topping it up regularly there is no inhibitors left in there. So any rust causes gases. Drain down and use the right chemicals to st corrosion and put in the right chemicals for the boiler. Steel boiler heater chambers have different inhibitors to aluminium. Use the right ones. Check the boiler is not drawing in air.
This is a lady who learned all this because I had the same problem. A new boiler I had fitted by British Gas. Was badly installed.

Lady again. Hard water area needs a filter on cold water feed. And I would say a magnetic thing that draws the metals in the water to a cleanable filter thing. Make sure the condensate pipe is not connected after a washing machine in line. Washer pumps water and bacteria back into the system. Sometimes there is no return valve to stop this happening. Idiots tack them off. Plus I really hope you sort it. Hopefully it just needs a drain a clean and the right chemicals. *** Liz

This thread is 4 years old!

I'm sure they have sorted it :smilewinkgrin:
