Cold Showers!

[Majjie]

Hi everyone.
I have a four year old Baxi Combi 80e boiler which I thought was wonderful - until a few months ago, when it started turning off the heat completely, once the water got hot, and providing a cold flow until it has heated it up again.

I guess it's supposed to regulate the temperature but it used to keep the water constantly hot, rather than alternating between hot and cold.

It isn't a problem for most things - but when having a shower I have to keep nipping in and out of the flow - not an elegant sight believe me!

I have a British Gas service contract and they have changed the temperature sensor - to no effect.

Is this something I just have to put up with? Any advice would be very welcome, thanks.

Not if you have a BG service contract.

Keep calling until its fixed.

When the boiler cycles cold, does the demand light stay lit?

If that's the green light above the tap symbol, then yes it does.

It sounds like the symptom of a blocked plate heat exchanger.

If that were the case then it would probably not be covered by the BG contract.

Oh ... b****r, that sounds expensive!
Thanks for your help anyway guys.

Agile was dead right ... it was a blocked heat exchanger.

The first BG engineer didn't have a clue - but the second one was brilliant. He booked a call back time and came armed with a new heat exchanger, a new sensor and a new pump - because he wasn't sure what was wrong.

Even after he'd found out it was the exchanger, he still fitted the other new parts anyway ... because he had them with him .... And there was no charge!!

I just thought I'd come back and say that some BG engineers are wonderful!
