I carry a couple of o ring packs for the Cdi in the van just incase I have to strip them apart.

What I hate on them is the ISO valves I was stupid and rushed so turned them off and both flow and return leaked! It would of been quicker and easier to take the boiler off the wall to swap them instead of stripping everything out of it.
 
The new compacts look awful to work on. I just don't understand why they make things hard to get at and why custards think they are the best I wouldn't put one in my house is what I tell people who ask for them :45:


My my thoughts exactly.

They are awfull to work on. Had to fit one while subbing with a mate the other day what a heap a $hi7. Stupid sliding expansion vessel that wants to fall out if its plastic runners when you hang the bracket and numerous other ridiculous design choices. I outright tell customers who ask for them that they must be mad and I wont fit them.
 
I've done that expansion vessel job about a dozen times now and can the boiler back up and running in about 2.5 hrs. No so the first time though! You have to follow the instructions on this job, there are no short cuts, which is where most fall down and where I did the first couple times. Now it gets stripped a new diaphram is also fitted and all the plastic manifolds are replaced, no messing about. Price 4 hrs and all those bits, the plastics are cheap. That way you get the job done on the second visit and its 100% for your customer and they think you are the mutts nuts when in reality all you did was not take any short cuts and just got the job done.

I like any of the classic range, great to work on. The heat exchanger is easy to service and parts are accessible. The Junior range are a pig to service and the heat primary heat exchangers are pants. Other than that they are pretty reliable.

First impressions of the Compacts for me aren't good due to access but they ditched the round heat exchanger which is good. The case fixings seem very fragile. I will have to get into the guts of one properly and see how easy they are to strip.

Really?

I've replaced nearly every part in these over the years, both hydro blocks, pumps, gas valves, fans, pcb's, turbine adapters galore.

In fact I think the only part ive never replaced due to failure is the electrode leads, although replaced one set because a mouse had chewed through it!

Yeah the odd fan and pcb but not to the point where I'd say it was an issue. Never a hydro block, but then that's something I've very rarely had to do on any boiler. Soft water and pressure rarely above 4bar if that makes any difference.

There is one thing that's starting to worry me though and thats the electrodes collapsing into heat exchanger and the boilers getting scorched beyond repair. I notice the new electrodes come with a small heat shield to try and stop the gasket crumbling.
 
Worcester " the installers choice" rubbish not this installer, we fit them on one HA contract the other three use valiants. There is not one single big thing that is wrong with them just loads of little things, like having to run the condense through the wall in 1"1/4, the jigs that don't quite line up, the flue screws that won't quite catch, and the condense trap you have to fit yourself. Grrrrrrrrr hate them
