Hi, I've a 16 year old Baxi Solo 15 HE.
Seems the boiler stopped running since 1 & 1/2 days ago- it tries to start up but locks out. There is water leaking onto the floor - just a small drip but consistently. I took off the outer case & the air box door panel; after a lot of searching I found the leak is running down the inside of the air box door panel on the rear of the left hand side. The leak is a jet of water originating from what seems to be a plugged port on the left hand side of the heat exchanger; not sure 'plugged port' is the correct terminology. There are signs that it's been leaking to a lesser degree through this port for some time as there is an amount of discolouration around this 'plug'.
See the not so good photos - 'Photo side HE.jpg' taken from front of heat exchanger showing a 'plug' at front & the leaking 'plug' in rear. 'Close up Leak jet.jpg' as name & taken with a poor endoscope.
I can now get the boiler to run by diverting the leaking water down a pipe into bucket & drying the Condensate Trap.

Anyone had or experienced a similar fail, is it possible to repair- is it a viable repair based on what it might cost & the age of the boiler?
Thanks in advance.

P.S. Added image of Heat Exchanger showing LHS which looks like mine.

It is difficult to tell and I’m not au fait with that boiler. @gas112 might know. However, imo, if it’s leaking from where you say it could be new boiler time. It could also be dangerous if it’s a split on the main heat exchanger. Locking out could be a wet wire/harness. Best off getting a gas safe registered engineer in.
 
Thank you all for the feedback, I know now what it's called & that it's not replaceable. As gas112 said even if it was a reasonable cost to repair, it would be a bit of a gamble.
Now decisions decisions- what to replace it with; could/ should I go heat pump or another gas boiler if so what type???
Appreciate you giving the time to reply above.

do not go with a heat pump us in the trade can get them installed for free under a scheme and there has been no uptake whatsoever so that tells a story .
The baxi 415/615/815 heat only boiler is a good boiler the difference in price is is purely down to warranty period as in 5/7/10 years
 
@gas112 very interesting that you have that insight. I generally like new technology but thinking do I need/ want to take the risk/ hassel at this stage in my life V'rs what will we be paying for gas in 5 years time (will real cost of heat from elec be lower than gas then).

People who've spent their lives working on gas boilers, like gas boilers! Surprise!
