Leaking overflow pipe from boiler?

admin — Tue, 18 Jan 2011 11:22:12 +0000

Boiler Type : Redring Dual Heat (DH12U) (Electric combi)
Boiler Parts : Main boiler cylinder, Pressure reducing valve 2.1 bar, expansion vessel with ball cock (central heating), potable expansion bottle (charged to 2.1 bar), central heating pump, PRV (CH), other check valves.

Right, I have identified why my central heating expansion tank is gaining water and then overflowing to the garden, but I am at a loss as what to do to fix it! Instead of the central heating drawing cold water from the expansion tank it is actually overheating the water and that is boiling into the feed line (could see heat vapour entering tank at feed line when I shone a torch it the tank + feed line is very hot). I have checked the ballcock valve in the tank and its fine, I have replaced the pressure reducing valve, potable expansion bottle, thermistat and DHW mixing valve, but all to no avail. The boiler doesnt seem to have any controls to adjust the pressure and I have tried every possible setting on the CH mixing valve as well. I have bled all the radiators every time I dumped the water for repairs then refilled. Arghhh!!! Does anyone else own one of these boilers or had any similar problems with them?? I really need to get this fixed as my neighbours are starting to get pi**ed off

Help,

Greg.
Thanks for your answer Turdy, when you say ‘burst calorifier’ do you mean inside the actual boiler itself? I forgot to mention that the expansion tank for the central heating is only acting as a cold water top up for the CH. This boiler is constantly on and gives constant hot tap water and the CH fires when called for with room stat. when I turn off the mains water it continues to overheat the water even when the central heating is off, and this is the problem theres to much heat in the system and its going to the nearest avalible exit at the expansion tank.When I turn the boiler off at the mains the problem desists. Ive just checked all the fuses on the Temp PCB but they are fine and i recently fitted a new ‘over temp cutout’ switch with copper probe thinking this would cure the problem, but it didnt. link to the boiler from hell:

The only components that are on the heating side are the pump,CH mixing valve and expansion tank.All the other components are for the mains pressure hot water.
If the overflow from the expansion tank is running but the ball valve is fine then you could be looking at a burst calorifier.The calorifier transfers the heat from the central heating tank to the mains water.As the mains water is at a higher pressure than the central heating water in the tank,the mains water will force itself out at any weak point.
Shut the mains off to the hot water supply and bail out some of the water in the expansion tank.If the water level is stable,but starts to rise when the mains water to the pressure reducing valve is turned back on then that is the problem and a new tank will be required.

My Natural Gas Boiler is not heating my house?

admin — Wed, 31 Mar 2010 05:02:36 +0000

My basement recently flooded and both my hot water heater and boiler were knocked out (both natural gas). I turned off the boiler, re-lit the pilot and confirmed the thermal coupler is allowing gas to flow. However, both my thermostats are set at least 10 degrees above the current temp and I’m not getting any heat (steam heat base boards). Any suggestions on where to go from here?

my water tank has a sensor on the bottom that senses for monoxide or flammable fumes and if it does sense some it will not light the main burners this might be of some help. best of to call a heating and plumbing proffesional. for this is a serious health matter

Are British Gas boiler engineers any good?

admin — Fri, 12 Mar 2010 23:06:02 +0000

I had water leaking from the back of my boiler and had to have a plastic jug propped up until he got here to my home. He said I’d a ‘burnt seal’ and he fixed it. However, it is still leaking with water, in fact, even worse than before. I have had to call British Gas again and they’re sending someone round today. I thought B.G. were good?
This is the second day I have had to take time off work and I don’t get paid!

That doesn’t surprise me for crazy reason
I wouldn’t trust anything about any part of B.G. and the ‘engineer’ obviously did NOT ‘fix it’ or they would not have to be coming back.
I also can not see a ‘burnt seal’ occurring in a Gas Boiler simply because of the way they are designed.
I can see some other reasons and the most likely ones are.
1) A faulty valve on the expansion tank.
2) A faulty bleeder valve/mechanism on the pump.
3) A rusted expansion tank.
4) Simply a loose joint which was probably never tightened correctly.
5) A bad seal on the ball valve which is used to fill the system with water (external to the actual boiler).

I have nothing against the employees of B.G. but I do with the organisation.
Also I would just like to say that the original engineer may actually have made an honest mistake!
Hey we are all humans after all.
I hope they sort it out for you this time.
Good Luck!

Edit: I think Tony P is absolutely ‘spot on’!
You should question the so-called ‘fix’ and not let him leave this time unless you are completely satisfied that the leak is repaired.
