Outrageous spare part prices for Johnson and Starley boilers!!

You can buy a boiler for £100??? Please point me in the direction of this supplier as I am need of a boiler for a house I'm renovating.

Hi,

Try replacing the coils with some resistive wire or power resistors.

cheers, Pete.

The resistors on a J&S Fan Speed regulator are a bit f'n big for that.

It's not two resistors, but four (two per ceramic)

OP - look at my website -

I'm the only sensible alternative, honestly

Is it a DC motor? If not, it would make sense to replace them with something a bit more modern...

Thank you Pete I like the idea of replacing the resistors but I dont think I have enough technical data on the components I would need to do the job. (theres very little detail on the boiler maintenance guide)

At the moment it looks like the best way out is to get Geoff to recondition the old fan speed regulator which will cost me £56 (including vat + delivery) (as opposed to £105 for a brand new unit) But Im seriously thinking about chucking out and replacing the boiler with a totally different unit whose part costs are reasonably priced.

I would still warn anybody considering buying a Johnson & Starley system - if your a pensioner make sure you budget for skyhigh part replacement costs.

Thanks gents SledgeHammerSteve

What are they like, are they resistance wire wound round a grooved ceramic former like in a radiant fire?

If so it should be fairly straightforward to measure the resistance of some of the original wire and rewind them.

Maybe you could just rewind them for the OP instead of reconditioning the whole thing.

cheers, Pete.

No dave, it's not, and it wouldn't From an insurance point of view apart from anything else, it would be a mistake to modify it.

You must be joking, look at the price of, for example a Potterton Suprima pcb,, or a Thorn (Ideal) Apollo fan

No, it's a 24 volt drive for the relay coils

Right. But don't you supply modified parts for other boilers?

In message , Dave Plowman writes

No, I don't modify, I repair to original spec..

I am very careful not to modify (other than e.g. replacing with a higher wattage resistor where suitable)

Hmm. Doubt that would stop a determined insurance company. ;-)

Its the same as with cars, buy all the parts, its about 4 times the price of buying the whole car assembled.

How so?

Are you saying that, for example a fuse should not be replaced on a board be cause it's not the original one fitted on the pcb ?

I supply fans and pcbs for companies who work for insurance companies

I guess its the same with all boilers. A new fan for mine is over a £100

What boiler?

If I have stock, I can send out up front

That price sounds average. Boiler parts are similar prices. Have Geoff look at it.
