How to clean heat exchanger

[fastnova]

Sorry the junior has the electronic overheat reset on the pcb not the manual red plastic button on the standard 24i.

fastnova is there not a secondary heat exchanger in a 24i junior?

 

[fastnova]

no diverter valve and the heat exchanger above the burner is the only one, it does both the hot water and heating. (has two seperate parts to it, ie. water is not mixed)

 

[yo1]

which worcester 24i junior are you talking about then?

 

[fastnova]

im taking this on the fact it is just a 24i junior rsf, not a greenstar? 24i junior rsf was discontinued in 2007...

 

[yo1]

ok, I thought it was a greenstar.

 

[fastnova]

Does the boiler have the controls on the front behind a drop down door, or are they exposed all the time? (greenstar behind door & standard 24i exposed)

Hi, it's not greenstar. The controls are exposed.
Thanks
