leaking problem with greenstar 24i condensing boiler

[mardey]

hi i need some advice i have a 24i greenstar boiler its only about 3 years old .Just recently i noticed that when i turn on the c / heating the boiler fires up ok but after about 10 minutes or so i starts to leak from the base of the boiler,im talking about the large chrome looking unit that looks like a tea urne .It seems to have a black plastic base with 2 screws on the bottom front that hold a plastic plate on . my water pressure was at 1.5 since i saw the leak i putit up to 2.0 bar .I can still get hot water as normal from the tap or shower but as i said once the water starts moving around the system the front base part starts to leak , sorry to make it sound so long winded ! any advice would be very grateful .. pete

Sounds like the heat exchanger. Can you post a picture. Back the pressure off to just below 1.5 bar. This will take the stain off of it.

thank you for replying to my post i will see if i can get a picture and as you said turn down the pressure ... pete

hi mate, sorry not got back to you still having problems with boiler .Ive since tirned the pressure down to 1.5 bar it was running ok with hot water nd c/ heating but on friday just gone it packed up .There is a little black line on the dial marked at 1 bar so i drained a couple of cups of water from a downstairs rad to 1 bar ,now boiler will fire up goes through a bit of a cycle then sounds like it gonna cut out but goes on again a couple of times then it gives up with resulting with red light reset button coming on , oh and while going through cycle its making a winening noise i did get a reply saying it may be the heat exchanger [what is the heat exchanger and wots its job] and the big thing that looks like a tea urn was getting hot last ,but now is not getting hot at all and still have a leak at the base of this large type of cylinder that looks like tea urn . Any ideas please ... pete

Sounds like heat exchanger. Is your condensate waste blocked?

 

[PuraTherm]

Get a qualified engineer in to look at it. This problem is going to require work that you have to qualified to do, i.e. Gas Safe.

hi mate , the pic you have put up is the same as the one i have ,i initially thought i might be just a simple thing wrong with it as its never giving me problems before ,thats why i was going for a bit of advice in case it was some thing simple like drop in water pressure ,and i dont no where the condensate waste pipe is and a bit concerned that the pipes dont freeze up as the weather is not getting any better .... pete

It sounds like you need a GSR engineer to look at it. Thoughts about frozen condensate disharge pipe. The condensate can't get away and backs up into the heat exchanger. This will cause the boiler to fail safe and turn off. It could be this, so check the discharge at the drain or where ever its terminating.

thank you for replying ,much appreciate your help ,i will check the pipe to see if its blocked if not i will call an engineer ... thank you pete

is there a fault light showing?
this happened to me last year and blew my circuit board

hi , ive been and looked at my boiler and found the condensate pipe was blocked up with ice where it came out of the loft onto the outside guttering the whole lot was solid ice took it all apart and cleared it all out , boiler working fine now just like to say a big thank you to for first replying to my posts and secondly giving me advice on seeking out the problem . it was very much appreicated .... pete
