Hi,
I'm at my wits end with my Ideal Mini S24 boiler. For the last 3 years I have had problems. Its on a sealed system. Every now and then the CH Flow microswitch doesn't make when CH called for ( ususally OK on Hotwater), because the hydraulic flow sensor pin isn't driven out far enough to make the switch contact.
The system pressure has always had to be at about 1.5 bar for it to work ( any more and as the system heats up - it approaches the 3 bar and dumps out the tundish.)
I've had the CH Flow switch hydraulic assembly out numerous times, cleaned it, replaced the diaphragm and cleaned the plastic venturi ( embedded in the body ). This has ususaly done the trick.... for a while until it all happens again. Every year is the same and I can't take it anymore.
Yesterday, I had the same issues but worse - No flow switch make on hot water or CH. I did the ususal thing ( all pretty balck inside ) but still no joy.
My thoughts are that theres muck in the system ( even though the system was installed 5 years ago ) and the ideal mini design just can't tolerate it. As we speak I'm sitting here freezing - looking at my miserably cold wife and thinking what to do next. I'm thinkiing about getting british gas to install a new ( different ) boiler to the tune of £2K.
Is the ideal mini s24 a lost cause? If I got a new boiler would I have the same issues? Is the ideal mini just too sensitive a boiler and a lost cause?
Any help very gratefully recieved.
