Does this mean there is nothing much I can do except log a ticket with Intergas?

Having the main water pipe buried in concrete in the kitchen floor is indeed tricky... I recently replaced my lead pipe with MDPE; 1) I hired someone with a micro digger from Gumtree to dig a 10 metre trench, it took around 2 hours but the micro digger hire (with operator) was a fixed price of...

Yes, this is what is being shown in the Nest manual (I connected all my 3 Nest Thermostat to the spurs feeding the boiler)

Still in test mode, zone 2 behave in the same manner in zone 1, ie: - it takes around 10 min for the boiler to reach 80 degrees (all radiators from the zone are warm) - then the boiler shuts down and temperature goes down to 64 degrees in a matter of seconds - the boiler kicks back in and...

Brilliant advice, I should have read the manual in more details! After a few minutes, the flow pipe gets extremely hot. The boiler reaches 80 degrees and then shuts down, which I believe is the way the test is meant to work (note that at this point, both zone valves are closed, the flow goes...

1 = 0 3 = 70 Both are default values

Zone valves all working good.

Well spotted, I just came across that setting earlier, it would seem my pump is working (those are pretty quiet by the way). PS: didn't remove the case off though.

You actually helping me, thanks a lot for your time. The manual says the following: Hence I will have to wait until tomorrow 9pm (been doing some tests), but I just found this setting: which seems to activate the pump, I can hear an additional noise (though as you said, this boiler is very...

No luck after draining the whole system :(, lukewarm water to all the radiators (from both zones) with the boiler being suspiciously quiet. Is there a way I can definitely rule out the pump being the issue?

Same issue using T-ON and the internal boiler programmer. I have 2 Google Nest thermostats wired as such https://www.diynot.com/diy/threads/2-google-nest-thermostats-for-2-zones-connected-to-intergas-rapid-32kw.579295/#post-5091543, I think it would have been odd for both to exhibit the same...

I have an Intergas Rapid 32 boiler which was installed less than 10 months ago, all new pipework installed at the same time. I have 2 zones, both controlled by Google Nest thermostats. The CH worked fine during the last winter, I stopped using it around May. However I just started re-using it...

I am a top floor flat, above me is a roof terrace with the chimney. Would it be suitable?

Not sure yet, it looks substantially bigger than the current one, hence the size of the enclosure might need increased. I would also need to install adequate drainage for the condensing pipe. I will know more at the next service when the back boiler is removed from the enclosure. If interested...

They are still permitted, mine is still working (touch wood) and get it serviced most years. I also had several gas safety certificates. It is just they do not make anymore, well it appears they only make a few and the literature around it is rare.

Thanks, this is interesting. I also came across another useful article https://www.superwarm.co.uk/can-i-still-boiler-flue-chimney/, one of the other possible boilers to replace back boilers is the Greenstar FS 30CDi or FS 42CDi from Worcester. Viessmann seems to have one too, but cannot find...

I was told that the flue could no longer go into the chimney as a gas engineer should be able to examine the whole length of the flue; even with the installing of inspection hatches the whole length would not be accessible (this is a flat). Therefore my understanding is that the flue should be...

As above, back boilers are no longer made, and all current gas boilers require a flue but I am not allowed to drill through the walls due to being a listed building / flat.

Thanks John.

You are correct John, I've been looking for an alternative central heating system for many many years, I've seen lots of central heating engineers during that time. The problem is that I do not have access to an external wall which I could drill for a flue as this is a listed building. The back...
