    Optima G3 - Changing a Sensor

    Thanks again for the advice offered by both of you. I'm wondering what I have started here though... For the record, I have 2 methods of doing it at my disposal now. I'll work out which is best for me on the day.

    Optima G3 - Changing a Sensor

    Hi, I have bought a pet friendly sensor for our alarm and I was about to go and snip the old one off and replace it with the new one when I realised this might set the alarm off... Can anyone tell me the correct procedure for changing the sensor? And if I do something wrong will putting...

    No hot water. Boiler faults, banging the lot! Idel Icos HE15

    Just an update for anyone interested. My brother came over but didn't have long sadly. We cleaned the sump, it did have deposits in it, although they were not enough to cause the sump to fill. I hadn't read this so we didn't try topping up with water to see how well it ran away, although the...

    No hot water. Boiler faults, banging the lot! Idel Icos HE15

    Thanks gas4you, he's already cleaned the trap (is the sump part of this?) It was full of crap and everything came on so he went off thinking the fault was fixed. A few hours later it was back to its old tricks. One of the problems is that when he comes round, everything is working, or it's...

    No hot water. Boiler faults, banging the lot! Idel Icos HE15

    To be honest, I'm not 100% on that! I have never seen a pressure gauge or anything braided, although there is no header tank in the loft - I think it's part of the cylinder. Just looked it the cylinder and it says "Vented cylinder/combination tank" So I assume that it's not pressurised?

    Sorry, not sure what pressure it's at. My brother is going to have another look today so if I remember I'll ask him what pressure.

    No hot water. Boiler faults, banging the lot! Idel Icos HE15

    Thanks for the answers. Pipework size is 22mm My brother also said on the phone yesterday that it was not possible that they keep filling with air, but that is what is happening! Works fine with just CH on, but as soon HW is put on, it as if something is forcing loads of air into the system...

    No hot water. Boiler faults, banging the lot! Idel Icos HE15

    Hi there, We have had plumbing problems of various sorts for a few years. We have had various people in, and more recently I've had by brother in who is Corgi registered and quite a well regarded plumber locally, but none of them seem to be able to fix things. Boiler is an Ideal Icos...
