Please help, boiler stays on constantly

[paulw440]

If anyone can help i would be very grateful.

I have a boiler in the garage with a hot water tank, potterton timer etc in the small back bedroom, all had been working fine, then just as all the plumbers and gas engineers were tucking into their christmas pud not only does the oven develop a gas leak but the boiler won't switch off, so with the timer off and the thermostat down, it keeps on going as if "on" with the stat on high.
Transco have disconnected the oven which i'll swap out for an electric unit but with the gas back on the boiler is going through fosil fuel as if its turkey leftovers.
Someone has mentioned a stuck motorised valve or a faulty frost thermostat as its been real cold of late??

Any advise on things to check would be much appreciated.

many thanks and a happy new year to all.

Clearly you dont want to engage professional help!

The normal remedy for the cooker would have been for a CORGI to fix the gas leak!

As far as the boiler is concerned, you have not given enough details for us to guess at the possible problem. We dont even know what boiler you have!

with the gas back on

Who turned the gas back on?
As it may be possible that a gas valve is stuck in the on position this should have been done by an rgi.

Any advise on things to check would be much appreciated.

Check that all relevant information is included in your post as our extra sensory perception can get clouded in the fog of the ether especially during cold spells like this

Clearly you dont want to engage professional help!

And clearly you don't want to offer any!

with the timer off and the thermostat down, it keeps on going as if "on" with the stat on high.

Please reveal which of the following components you have:

1. Programmer.
2. 2-port motorised valve.
3. 3-port motorised valve.
4. Room thermostat.
5. Cylinder thermostat.
6. Pump.

Also, the make and model of each would be useful, together with the boiler make and model.

Its - 0.2°C outside here tonight.

Inside its gone down to 20.9°C as the heating timed off an hour ago.

Luckily the walls have cavity insulation and cast concrete internal walls with a high thermal mass so it stays pretty warm for hours after the heatv source goes off.

The kitchen has insufficient heat output so in very cold weather we close the door to the kitchen and it goes down to about 19° there during heating times if there is no cooking being done.

Is there one single syllable of that post that helps, or is relevant, to the OP?

Hi guys,

thanks for the responses, we're away at family today so have logged on from there, i honestly didn't expect such quick responses over new year, but greatful!!, i don't have all the info you require to hand, to put your minds at rest a corgi engineer turned the gas back on and isolated the oven but said he didn't specialise in ovens so didn't attempt a repair.
Of course the easiest way would be to call an engineer out and fix it all, but i honestly can't afford that, i new electric oven will cost around £140 and i can fit it, I can't risk and engineer coming out and then saying after a call out fee and minimum hours work that they can't get the parts to this oven because its to old, as for the boiler i found frost thermostats for around £25, I really need to try and fix this myself.

I get the info posted in a few days when we're back home, thank you for your time.

The frost stat could well be working correctly but there is no pipestat to turn boiler off.

 

[paulw440]

pipestat?? the system has been working fine for years, would it be the current pipestat has failed?? if so were would it be in the system? near the boiler? near the hw tank?

Sorry for the daft questions, V8 engines, ring mains, circuit breakers, electricity i'm ok with....... central heating is still a bit of a dark art to me

The pipestat is usually linked in with the frost stat.
When the frost stat brings the boiler on (frost protection) the pipes will get warm then the pipestat will turn off the boiler so as not to be running all the time, only there for protection!
