worcester junior main heat x replacment.

[Ollieg]

I have to replace the main heat exchanger on a worcester junior tomorrow part no 491878.
Having done this 3 weeks ago on another boiler and having real trouble (2hours) getting it off the pipes, I would like any advise you guys can give.

Thanks in advance.

Call worcester 🙂

there is a 10 year warranty on these heat exchangers and they will replace free of charge 🙂

Its an old boiler, bithermal heat exchanger. Trust me, I wish i could get worcester to do it.

They've been fairly easy when I've whipped them out, granted on the floor of garage getting them ready for the scrapie.

Pay worcester, they do a fixed price repair, it's very reasonable if you need a heat ex doing

I've got a glowworm ultracom main heater exchanger if you want to do it ? I told her to get a fixed price repair glowworm or buy a new boiler.

Nitemare job done a few the best way I've found is heat up the pipe where it sits on the heatexchanger it melts the orings so comes off Easier but b mindfull of the wires that go up the left hand side of the boiler as not to melt them

Heating the pipes is exactly how i done it last time!!!!!
Id love an ultracom heat x any day. Id rather fit a 937 shunt pump than do this worcester heat x.

Parts center made a balls up so I get to do this tomorrow. :56:
