Would be the hole lot if can't get the cartridge

Yes I have . See attached. Thanks

Do you have a pic Matt?

Is it possible to swap a concealed shower without removing tiles if can get a similar model.

Previously it had a kit like this

Has anyone done a toilet repair on a toilet that has a flat plate closed coupled kit. So there are indentations on the toilet cistern for the bolts to sit no in the metal close couple kit. I did one the flate plate and donut was almost...

Thanks flushing with x800 seems to have cured it.

I see from another post that its a Alpha CB24 which has a minimum output of 9.3kw and a max of 23.3kw. All gas boilers fire up at ~ 60% of max output, in your case, say 14kw, the boiler should then modulate to maintain its SP...

Thanks so I rang technical they told me to do a test on the divertor valve. I thought this would only possibly cause a problem with the hot water. But they said it can cause both to cycle. Unsure why it settles when hot though. Will try...

It does seem a good explanation for it.

Thanks. With regards to point A. Once hot it doesn't cut out on hot water. I'm correct in saying the boiler doesn't modulate down in hot water mode is always on max? But very good points

Assuming it's a gas boiler, I have two guesses: (a) when the system is cold the boiler tries to run at 24kW and cycles due to lack of circulation but once everything is warm it modulates down to a level that the circulation rate copes...

Just at abit of a lose why it settles when the boiler gets to temperature

Its a 24kw obviously heating load be nowhere near that. Lack of flow possibly low performance of the pump?

Any ideas what could cause a boiler to repeatedly cycle on and off on both hot water and central heating. Until the boiler gets to temperature then settles down and stays on for both.

Alpha cb24. Due to age of it was wondering if there was a way to clean without disturbing the boiler

Any idea how they make sure it's going through the plate when put in the filling loop? As running the hot tap will divert the water that is presently in the heat exchanger around the plate. Run heating for a second before. Running the...

Via the filling loop eg like this View: https://m.youtube.com/watch?v=31Ww_FVMtHI

Thanks I'll have a look in to the fernox F3. Is it seen as, as strong as the x800?

Do they use method where you can syphon the clearer in to the main hex? Obviously closer to the plate then. Or just add the cleaner to a radiator/filling loop

Yes

Got to be worth a try then.

That’s what baxi do they use fernox can stuff

Does this allow the plate heat exchanger to be cleaned without taking it out of the boiler? Or am I thinking abit over the top.

Its a combi yes. Do you think it may work?

If putting this in a system would it at all help clean a plate heat exchanger if repeatedly turning the hot tap on so the C/H water runs through the plate? I imagine not or everyone would so it instead of taking the plate out. Thanks
