It could only happen to us Boiler has shut down E110 I think

[McCabe-Thiele (Ted)]

The hardware fitting work has now been done but the boiler is refusing to fire up correctly so a second Baxi engineer is currently helping with the diagnostics..................... 

Update:-

It's had a load of new parts including the main heat exchanger & condensate tank assy.
7.5 hours after first arrival & it's sorted.
Thank goodness for boiler insurance that includes servicing a snip at £17.15 pcm on a 9 year old condensing boiler..

I knew it would end up a nightmare for them. Can you see why I avoid doing them, had a few late finishes over the years. Hopefully you will be good for a few years now.

Just had to put a flow valve into our potterton he15, it had a new ebay one 6 months ago along with heat exchanger but O ring to outlet pipe started leaking and there is no part number plus nobody knows the size!! could only get the baxi one localy at short notice at 3x pattern price

Boiler stopped working again yesterday fault code E158 - condensate system again.
Fixed this afternoon by Baxi engineer - poor connection on condensate pump.

Baxi Condensing Boiler is 9 years old this year with the current BBU 15 HE (lounge back boiler unit) now out of production.
I suspect getting boiler breakdown/service insurance cover might be unavailable once it's ten years old.

We are limited as to where we can fit a replacement normal condensing boiler as the lounge unit is in the centre of the house using a special plastic double chimney arrangement to draw in fresh air in from the chimney top.

I do not want a boiler unit in either of our upstairs bedrooms or in the bathroom (too small anyway.) The front lounge /room is not really suitable that leaves only the kitchen (major rework)or at a push the downstairs toilet.

Only option I can see would be in the loft but access for servicing is less than ideal not to mention all the pipework being re-routed.

Aside from the price a heat pump would have to be piped from the rear garden through our Conservatory that spans the whole of the rear of our home. We are well insulated - all our Porcelain floors would have to be dug up to fit underfloor heating anywhere.

The future might have to be Night Storage with no doubt a load of re-wiring as a 13 amp socket is probably not good enough.

sort of still on topic, we had problems with the condensate liquid eating through plastic pipe as it is very acidic. anyway, i came across a product called condensulate in a 10m coil, so no leaky joints

Father in law had his boiler moved from bedroom to loft about 10 years ago or so. They insisted on good access with a quality fitted ladder. But it worked out fine.
My father had storage heaters. They all had separate 20A switched d/p outlets.

Our condensate pipe was replaced in 2018 by the contractors following our house fire in Nov 2017.
They fitted a more rigid type of translucent pipe that is routed through the rear of our fireplace into the kitchen waste water system where it is connected by a neat bespoke connector similar to the Speedfit type of unit.

Recently had exactly the same problem. The pipe in our house runs behind the plaster board between the kitchen and bathroom. The joints were attacked by the acidic condensate and only found out when a patch appeared on the bathroom wall. The studding and insulation were soaking wet. I’ll check out condensulate,
sounds like the perfect solution.

Working in chemical plant, all of the pipes were rigid pvc type, with glued together fittings for terminals, routing etc.

One of the easiest to work with too, just a blade type pipe cutter and all glued joints, highly impervious to high and low pH chemicals and ultra reliable.  Absolute doddle to design and install.

Not sure where your airing cupboard is Ted but a good option can be a Combi in that position. We do plenty of those conversions, it’s pretty standard and works well, only real things to overcome are the gas supply, the flueing and the condense waste.

[McCabe-Thiele (Ted)]

Unfortunately our airing cupboard has no space for the boilers due to the slope of the bedroom roof.

Ideally I want to keep my hot water tank & immersion. I'm not keen on mains hot water  pressure on my 50 year-old radiator pipes.

Hi Ted

I think the clue to why you got problems is in the name of the boiler unfortunately, We went for a Vassmaan back in 2019 and its run like a dream ever since and their was only a little difference in the price.  Hopefully your get it fixed very soon and be toasty warm .

Ted. I'm pretty sure all back boilers were finally phased out in 2020 (Hurrah). The Viessmann boilers are reported to be suffering from burner box corrosion, the larger ones have even had a recall/replacement notice that cost the company a lot of money. When you say a bad connection to the condensate pump, was that water or electrics. The pumps on those things are a nightmare, if you have wooden floors you can replace the pump with a decent one. There's not room in a BBU for a better pump so we put them under the floor next to the chimney breast and pipe/wire to there. Obviously the pump needs to be lower than the heat exchanger so that wont work on a concrete floor.

I don't know the layout of your house but there are usually options. Is it a house or bungalow, is it concrete floors, are there laminate/tiled floors everywhere, is there room outside where you could build a small lean-to boiler room, is your chimney on an outside wall etc.

In 30 years as a gas engineer I have never failed to find a way to replace a boiler. An example was a back boiler replacement that we couldn't figure out. In the end the chimney breast (on an outside wall) was opened up and a combi put inside the old chimney then they had a cupboard front fitted. There was a lot of other work to it but that was the jist. Just some ideas for you.

[McCabe-Thiele (Ted)]

I believe only Baxi made a condensing boiler to directly  replace their famous Baxi Bermuda back boiler item.

When our house was built a Bermuda model was fitted from new in 1967. That first boiler lasted until 1987 when it was replaced with a similar unit with a more modern front gas fire. The boiler sits behind it in the fireplace recess. The second boiler was replaced in 2014 with the current condensing type.

With Baxi  boiler life of 20 & 17 years I stuck with Baxi due to a good experience with the brand plus no one else made one that would  was a direct replacement. Obviously lost the front gas fire for a modern electric unit due to the special chimney arrangement.

[McCabe-Thiele (Ted)]

I agree Roy there must be other options, the local firm that fitted the BBU seemed to think the rear bedroom was the only other viable option.

We have solid concrete floors no wood on the ground floor. The. Kitchen option would mean having our consumer unit moved plus a relocation of Gas Hob & Oven Units.

Our outside walls, one side is our driveway, other side is our neighbours drive. Rear wall has full width Conservatory, front wall is  the building line. My worry with the loft is it's a low height as it's a Dorma- Bungalow design. The existing header tanks would struggle to get them raised above the boiler.

The rear bedroom option might be the best of a lousy  set of alternatives. Our boiler never faulted for the first 3 years. It's only since our serious fire that the boiler has started faulting.

With a bit of luck we can squeeze another 4 years out of what we have provided the insurance cover is not prohibitive.
