I popped out in the car this morning to be called up and told that the carbon monoxide alarm in the garage had gone-off.

The boiler is in there, so British Gas came around in no time and cut-off the gas!! Someone is going to come back and test the system before we get heat again!

My lad then kindly explained that it went off last weekend when I went out in the car! So its either a leak and taking the car out moves it around or the car is setting it off in someway.

Any suggestions please?

Assuming that you start the car in the garage, let it idle for a moment or two I would be surprised if the alarm didn't go off.

Next time you go out you could push the car out of the garage, close the doors then start it and see what happens.

Hope it works...you don't want the heating off too long in this weather!

Thanks, I have never had a problem before! Hopefully, it is the car, not the boiler.

Its the battery !, they will do you for £100cool It is probably a room sealed boiler so the chance of carbon monoxide is zilch ..

A carbon monoxide tester for a boiler if put near a car exhaust will give a huge reading and left there too long will require the 02 cells to be replaced.
So it is a good shout that you are setting off the alarm with the car !
As Daz say's if its a room sealed boiler (takes its air from outside) it is very doubtful you even need it !

It is a condenser boiler with an outlet that chucks out lots of steam! I assume it takes in air through that as well.

British Gas are 20 minutes away and its kin freezing in here!

It will have been National grid who came around and turned it off as you have reported a possible CO escape so they have to make safe.
And yes it will more than likely be the tvr as I've seen it happen before.
As for whether you need a co alarm with a room sealed boiler, well I bet you have a smoke alarm and its only the same, I'd rather have it there just in case something goes wrong than not have one!

The only difference between a non condensing and condensing boiler is a secondary heat exchanger which extracts heat from the hot flue gasses .Probably about 2% more efficient but cost twice as much to buy .

Both are room sealed boilers.

All sorted and the house is getting warmer again! Lots of extra screws in the flue through the garage but hard to believe that will change much!

Thought this was a car forum ? But for what its worth Daz is right !
A electronic ignition boiler is only about 2% more efficient, I believe there is a government web site with the info on when band G went on the scrap scheme.

Guess again! non condensing boilers are anything from about 60-78% efficient, A rated condensing boilers are generally around 90% efficient and yes I agree this is the TVR section so probably best to call it a day but might as well get the facts right.

You know that B rated condensing boilers are little more than adapted C rated fan flued boiler . I personally think that combi boilers should have lower KW out put for heating .. You know and \i know unless you have the right size KW boiler it will not be condensing all the time unless you have underfloor heating (combi). I don`t think that the B rated combi boilers even condense on hot water mode .

You know after a 55 degree return condensing does not happen .. So how efficient is the condensing boiler?

To answer Grahams original question yes your car is almost certainly responsible for the alarm, cars can produce lots of it rapidly in confined spaces cool from cold you have raw poorly burnt untreated exhaust fumes to boot frown

And faint black lines on the floor behind the car!

Great thread resurrection!
