Repair or new boiler?

[abc23]

shame you're in somerset I took out a classic other day, you'd be welcome to any parts including heatex. I justs get them picked up by a scrap man.

Have you still got the parts? We would be very happy to pay postage costs for them if you have - heat exchanger and thermostat control box, which took a soaking. Thanks

the trouble maybe lying in the pipework! if the pump had gone and the heat ex cracked there maybe a case of sludge in the system that corroded it!! what colour was the water? a powerflush is not a cheap job!!

Sludge would not cause corrosion in a cast iron heat exchanger, in fact the only obvious problem with CI is frost damage.

A power flush will be needed in any case, especially if a new boiler is installed.

The HE cracked because the pump was totally broken and so the water was boiling, so the HE got weakened and finally cracked yesterday. (As is OP, the pump was replaced a few weeks ago).

The water was clear, apart from a small amount of brown unknown substance.

Sorry can't buy that. If what you say is true then you have a very badly designed system, even bordering on the dangerous.

I can buy that a cast iron heat exchanger just springs aleak, I've scrapped two boilers because of it. The one I've removed is at a job I'll be going to today, but I can't see the ladies at the post office counter accepting the heat exchanger, it's very heavy. ANyhow I'll see which model it is and let you know.
