isar

Good evening chaps. Hope you are all having a nice bank holiday. I have got to go and look at my 1st one of these boilers tomorrow. I have read the posts on here mentioning how bad they are. From what they say it sounds like the phex is blocked. But do you tell the custard how bad the boiler...

Hi, new to here, I have an isar 35 issue, dhw turned on it heats up then overheat stat kicks in cools down then kicks back in and so on causing intermittent hot water through taps. plate heat exchanger has been replaced, system is clean and heating works fine, any ideas? cheers

Boiler not working - display controller not lighting etc Hi to all! i have taken on a property with an ideal isar gas boiler, it's fairly old like 8 years I think! the boiler has been turned off for around 1 year or so, there is gas connected and water in the system, when turning on the...

Only got a PHEX and a condensate trap left..any offers?

I have some brand new Isar bits if anyone wants to purchase any? All brand new in boxes etc 1x V9 board 1x Consensate Trap 1x PHEX I have an isar and had them for repairs but I'm going to throw a logic in so not needed.

Was out to an isar he24 a couple of days ago after it leaked (lots) from what I thought was the plate lip seals. Went back yesterday with a washer kit and replaced all 4 lip seals and then noticed the hot pipe O ring was weeping so changed that as well. All was good or so I thought. Just got...

It's one of those fault codes that ideal don't have in their MIs!! I did have one before, but can't for the life of me remember how I fixed it, it's an intermittent fault and the customer can get by, by reseting the boiler. Any thoughts?

Door off! Checked condense which was clear, checked flue which was clear. Took off burner and checked probes which were fine! It's gotta be an air flow problem....would a dodgy fan cause this? Cheers lads

Any one got any suggestions ? 2 pcb 1 fan 1 pump. Got the right spares kit in van..... New boiler !

Has anyone removed the phe on an Isar HE35 out through the front of the boiler ? The one I've got to do has a stand off kit with all the pipework nicely blocking off any chance of getting it out the back, I think the 35 has a bigger phe than the other models as well. cheers blod

Hi there, My boiler is a Ideal Isar HE30 and over the past month or so I've been noticing a leak from inside our boiler. The pressure drops to well below 1 which makes the central heating not work properly upstairs, if we top up the water pressure it leaks faster. I downloaded the boiler...

Landlady claimed it has been serviced every year and gas safe cert every year, cannot produce any evidence of service records for either, landlady getting irate on the phone as i said i will have to report this to gas safe as putting the tenants life at risk. Tenant has been there 5 years...

Hello I need a bit of advice here, i've been having issues with this boiler recently, and now after a plumber fixed a water leak on the boiler I am left with no hot water. To cut a long story short, today a plumber/engineer came to fix a water leak which turned out to be the 'o rings' of...

intermittent fault code l8 no power to fan . is it pcb

Serviced my first one this morning. Wall hung pile of shyte. Discuss.

Hello My boiler is being a twit, and unfortunately I am not clever enough to solve the problem. The L-F fault according to the manual something to do with the flame detector...so I replaced that. Same L-F fault....no difference. (I'm freezing!) So...I read through some of these...

Hi all ,got a noisy 5 year old Isar 30 he combi to look at this weekend ,every couple if minutes it sounds like someone is drilling then it goes quite for a minute then starts up again...anyone know what this is likely to be or known problems with these.....only does this after it's warmed up...

Had the privilege today to work on one,loud bang on firing up noticed lot of gurgling from plume diverter so as suspected blocked trap and it was well and truly blocked lots of poking and boiling water to clear. Anyway removed access plate bottom of heat exchanger cleaned out, Boiler fired up...

hi all,been to a isar he 24 today that wont shut down on thermostat, tested flow thermister at room temp around 2k ohm. swaped flow and return therms and it now shuts down.new thermisters to be fitted tomorrow,my question is what is the purpose of the return thermister. thanks oldplumb

Had to change a pump on an Isar, apparently you can only change the whole manifold now or something. So drained boiler and removed pcb for easy access. Fitted all back together and I'd put the power in the wrong block. Blew the pcb. Fail number 1. Put a new pcb on, got a variety of error...
