Any central heating engineers?

[reefer110]

As above, wondering if we have any one who knows their way around a central heating system?

Here's the story... had the boiler serviced yesterday morning, all seemed normal but after the guy left myself and the missus remarked how much warmer the house seemed, I could feel the heat coming from one of the rads in the kitchen from 2-3 feet away...not experienced that before but thought nothing more of it.

Around lunchtime today we heard an almighty sound, hard to describe but sort of a loud whoosh. Went to the utility room where the boiler sits on the wall to find water coming through the led light fixtures etc. Turned the boiler off, etc and called the guy back that did the service. Having cut away a panel for access we discover that one of the flow/return pipes has burst in two places.

Now I cant prove anything but I feel there may be a coincidence here since it was serviced yesterday and 24 hours later it gone pop. He's been back and sorted it but I'm not 100% confident to leave the heating running for fear of the same thing happening.

Anyone able to suggest a likely explanation and also point me in the direction of what I can actually check myself? Having had a google all I can assume is that the flow/return has got way too hot and given up.

Any suggestions most welcome

TIA

My guess would be he's knocked a clip on flow temp sensor off a pipe and the boilers merrily heated itself to boiling

If you're worried I'd turn the flow temp down temporarily and check it clicks off before rads get excessively hot

Thanks very much for the suggestion, I'll check this in the morning.

These are the two places is ruptured. Initially I though the pipe may have been expanding/contracting over the past 4 years and worn itself thin against that metal strap in the top pic.... but then, maybe a foot to the right I found this other hole. Nothing around that area to rub on.
