Incorrect boiler installation ?

[Rilla]

Hi, I've recently had a new boiler fitted under the ECO scheme.
The engineer that carried out the installation was in a constant rush.
After the installation he checked all the radiators were hot but I pointed out a loud banging/gurgling noise. He said it was air in the system which would settle down.
However after he had gone it kept occuring and I realised it was boiling water in the feed/expansion tank which was overflowing through the overflow pipe.
On further investigation I think the pump is on the return rather than flow pipe which I am thinking would cause the overheating problem.
Should I have the same engineer back or would you suggest another plumber?
Could this have damaged the boiler (it is a Worcester ri erp+ standard boiler)
Thanks in advance, Ril

It would be fair to ask the same engineer to put right any faults/anything you are unhappy with. Give him the chance, failing that, then maybe ask another.

I can’t see why putting the pump on the return or the flow would cause overheating of the boiler.
The feed and expansion tank could be getting a pump over from the system, which your installer should have made sure was not possible.
Would be good if a trusted engineer could eyeball the boiler plus wiring and pipework before you call the guy back. He is responsible for having it operating properly.
I am not gas qualified, but some of the gas folk on here will advise

My understanding of eco schemes and grants is that the fitter is only given a certain amount of time/money to do the job - might explain the rushing.

I'd always contact the installer first to rectify any issues. Have you got any pictures of the boiler, airing cupboard, pump location and the tank which overflows?

How much work did he actually do? In my limited knowledge of these the scheme only funds the boiler replacement and anything else is to be funded by the homeowner, did he replace the pump?

The grant my grandparents got was for boiler, filter, pump, 3 port and new timer stat etc. They didn't flush the system though

Give him the chance to put it right then go from there it could be a few things really. Kop

Thanks for the quick replies on a Saturday evening.
I've took a picture of the installation if it helps.
The pump flow is left to right.
I have clipped the temperature dials on the pipes.
Thanks.

Could be the pump is positioned to close to tank or needs speed turning down abit.

I knew a guy who did a load of them, mainly combi’s but a few heat only’s, was told that anything other than the boiler/flue/small amount of pipework and fittings/timer-stat was down to the homeowner to pay for, it wasn’t unusual for him to charge for running a new gas pipe, plus they only got 4hours to do a full job, no wonder your grandparents fit never got flushed.

Suppose it depends on the company offering the grant. 4 hours is ridiculous though. Realistically all your going to attract is cowboys to undertake this sort of work.

There Will be an arrow moulded on the pump body. Which way is it pointing?

 

[Rilla]

It's pointing to the right. Cheers.

Looks like the pump is the wrong way round then

And the filter on the flow?

 

[Aire]

I could be wrong actually, to be honest I'm not entirely sure why it's piped up like it is

And the filter on the flow?

I wondered about that. However think what he means is the pump is pumping the wrong way?

 

[Rilla]

The engineer is due to come back next week so I will let him have a look then.
Do you think I am safe to use it in the meantime?
I've just turned the heat setting right down and it is working but not getting really hot.
Thanks again.

 

[Aire]

And the filter on the flow?

Yeah just checked the boiler diagram and the filter is on the flow so that would suggest the pump is pointing the wrong way

Not sure to be honest. The flow direction of the pump is wrong and the return pipework also looks wrong, because the water isn't going to circulate properly the boiler will constantly overheat and shut down. Because of the incorrect installation the warranty will also be void. I personally would turn it off until the problem is corrected.

So its positioned under negative pressure?

Agree 100% with that. Hopefully he's out first thing on Monday to swap the pipes around.

Even through eco, its part of the warranty to flush the whole system!!! Otherwise voids all warranty by manufacture. These plonkers who do these eco schemes are given £500 to convert and swap and rush. Ive seen them rush in and do a 3 day job in 1 day. It just doesnt work and no wonder i get called to these installs for faults. The scheme is a Sod take.

I think sometimes the installer is only given a day too, so that the customer isn't left without the use of their boiler. One of my ex work colleagues when he set up on his own, signed up to install for a local housing authority. He needed the work initially so accepted it but he was only allowed a day for a boiler swap and was only paid for 1 day. Not the same as an eco grant but they probably work on the same principles.
