I recently had a new boiler fitted into my flat and have some concerns about the solution provided for condensate.

When the job was first scoped out I was told that a pipe would be run outside to deal with the condensate, which would be a challenge because of the property but doable.

I stuck with the condensing water boiler because it was going to be a huge hassle to change to combi in my property, which was confirmed by all of the installation companies that gave me a quote. Didn't seem like any real reason to change either, as long as everything worked and my house had a working heating system!

Anyway, the guys I arranged to do the job came out and although there was a couple of visits required to get things working they got everything fitted and the boiler was working perfectly. I noticed there were no pipes going outside, so I did ask what happened to them. I was told at this point that they'd found an alternative solution that meant they didn't need to. I probably should have asked more questions, however I know nothing about boilers so, possibly naively, just accepted what I was told.

However, after a couple of days the system started making a dreadful sound, right underneath the boiler itself, and it just wouldn't stop. I had a look at where the sound was coming from and it was a small contraption inside a plastic box which was filled with water. I took a video and messaged the installer, who said that I just had to remove the plastic box and empty the water. So I did this, but a few days later it just filled up again and the same sound returned. I was then told that I would have to keep changing the box when it fills up with water. At this point I was a bit miffed. Was this normal? I had to yank the contraption thingy (I don't know what it is, you might have guessed) out of the plastic box, pulling some pipes out as well, with condensate dripping on the floor in the process, and take the plastic box and pour the water down the toilet. I'd never heard of anything like it.

Fast forward about 6 weeks and I'm going through this process every 2 days or so, sometimes daily if we are home and have the heating on a lot. I have contacted the fitting company and they have said they'll book someone to come and provide an alternative solution, but that they informed me that there isn't really a viable alternative that follows proper procedure.

My concern here is I feel like I shouldn't be changing condensate manually every couple of days and it just seems like a ludicrous process and I can't quite believe that it was ever fitted this way, without even notifying me at the time that this would be the case. The guys were really helpful and had to deal with a lot of obstacles when fitting the new boiler, which I really appreciated and I feel slightly guilty about raising concerns on a forum. But the honest truth is I know very little about boilers and I just wanted to check if I'm being unreasonable. Maybe it's a normal solution to have a plastic box that the condensate fills up into and then needs changed?

So at this point I'm just looking for some feedback on my situation and whether it all sounds standard or not. As I mentioned, the guys I got in were really helpful on the whole and to be fair they have said they'll come out at some point to look at changing the current set up when it comes to condensate. I'm just a little concerned about what's in place and having spent £2,500 on a new boiler I'd like to know it's all been fitted properly!
 
Having moved the host so it wasn't kinked, there has been little change in the issues unfortunately.

The pump still fills up within about 48 hours and has to be emptied as it starts whirring out loudly and not working properly.

I've not heard back from the installers, I do feel they are stalling quite a bit now - I've been asking them to come out for a number of weeks now.

I asked what the alternative is to having to keep changing the pump and I've been told all they can do is put the condensate into the stack outside, but they aren't supposed to do that. Surely my only 2 options can't be to change water from the pump every 2 days forevermore or to improperly have it going into the stack outside...?
 
Doesn't sound like the installers will be back tbh. Time to take matters into your own hands so check out some of the suggestions given earlier or start by disconnecting the hose from the boss and running it in to a bucket to see if the pump is even discharging.

Sounds like the pump isn't working. It should be possible to fix it. What type is it - diaphragm, centrifugal, peristaltic or what?

Why is there a pump anyway, is the boiler in a basement ? Centralheatking
Centrifugal pump and doubt it is in a basement as OP said flat with limited room to run pipes that said I still stand by "Incorrectly installed".
 
The Grundfos and the Saniflo version of these little pumps can be wired in such a way that if the pump fails then it cuts the boiler hence I asked about the installation manual being left on site.
 
That said, this system should still be totally workable and the pump should run and do its job properly once the issue is found and corrected.
Agree unless the poor little thing is now buggered by pumping against a closed head.
 
Could be, but most centrifs draw less power at closed valve than at duty point.
Time the OP took it to bits and investigated. We've done all we can IMO.
Wasn't thinking of motor windings damage more of bearing damage and OP hasn't reported back on other findings so bit early to start dismantling it.
 
I would bet that your boiler benchmark form/certificate has not been filled in with the installer details.

If it has contact gas safe & request an inspection as you have no way of knowing if it has been installed correctly without an independent inspection.

Sounds like your installers may not be all they seem.

I would of been straight around to correct but certainly would not have installed like that as it looks a bit lashed up.

Hope you get sorted,

Andy (Allgoode)
 
It's never too early to start dismantling! :)
How will he diagnose the problem otherwise?
I would start at the solvent weld joint as advised then pull the hose back (currently runs down and back up - Big no no!) and lay it on the floor with the open end in a bucket.
That way you prove if the problem is the pump or the pipe run and take it from there.

I'd have thought the OP would have checked obvious things like blockages and kinked pipes before posting on this forum.
I can't see how it couldn't be fixed, or at least the fault identified, by somebody with a modicum of ingenuity.

Assume nothing, the OP could work for NASA but that doesn`t mean they understand basic plumbing :)
Agree re the fixing or fault being identified however I prefer to see if the pump is working before (Quote) "Taking it to bits". :eek:
 
Bet they got the holesaw out. And goodie...just because a benchmark hasn't been filled in on paper doesn't mean it hasn't been completed...you still living in 2015 or sooo? Apps these days pal.
 
Evening,

Sorry for not updating, was away on holiday this week so haven't been around home.

No change in the status of the boiler/pump, or that of the installers returning.

I tried to even out the kinks in the hose but the majority of it is underneath my floor, which is not accessible now - without pulling up carpet, underlay, plywood and floorboards.

I'm also an utter novice with anything plumbing related I'm afraid.

In relation to the pump, if it was working as it should would it still make such a loud noise when the water gets to the top? How long should it take to pump the water out? I haven't really put it to the test since it first started doing it, when it got nowhere after about 20 minutes and the noise was extremely loud.

I suppose I need to know if the system is even working in any respect, even if I'd rather there was never a pump put in to begin with (as I said before, I should've asked more questions about what they were doing but still feel they should have explained more as well).

If they don't come out to sort it, would I have grounds to raise a complaint?
 
it should empty within 10 to 20 seconds they really are quick so you definately have a blockage you need to get them back
Can't go and tell them that you definitely have a blockage. Suppose they return and blow down the hose and declare it is clear?
From the limited info we have I'm fairly sure it is installed beyond it's capabilities so either the installers return and prove it is working or the OP pays someone else to look at it.
 
Thanks for the continued feedback. I've sent them another message, if I still get nowhere I'm just going to pay someone else to have a look at it. If they determine that it's not been fitted well/properly then I will escalate my grievance with the original fitters.

The company that put it in have told me they'd provide an alternative free of charge, when I advised what the pump was doing. Strangely they never suggested I should keep this option or even ask me to do any checks, they just said it'll make that loud noise and the only way to sort it will be to keep emptying it. Almost as if they weren't surprised that it was a problem. I would've thought if the install was working as planned they wouldn't have immediately offered a free alternative solution without even suggesting the current setup could be maintained?

That said, they have yet to come out so it could all be false promises.

Rather than getting the pump working I've been told the only other option is to have the condensate going into the stack outside, but at the same time advising that this isn't best practice. Should I be concerned about that?

I feel a tad frustrated as I feel I'm only being given 2 options; 1 of which is to have this pump screaming every few days and having to manually empty water out of it or 2 doing something which we're not even meant to. I'm in a small property with the boiler immediately against the outside wall, it doesn't seem that crazy a set up that there are no good options....

With this option you have to manually empty it every few days, but you don't have to his pump screaming. Just disconnect its power supply.
but the majority of it is underneath my floor, which is not accessible now
The hose connection on the pump must be accessible. Can't you run a temporary hose from there, if only into a bucket, to check if it's working or not? And if it does, you've identified the problem.
 
If you contact the manufacturer with the model number they will send you a new hose. Use it to test the pump whilst leaving the original where it is which I still say is routed incorrectly.
The top section housing the pump/ motor must be seated correctly on the tank for it work.
 
Morning folks, and happy new year!

Apologies for not posting a further update on this one, been a bit busy over the past few weeks.

So, the installer was due to come out to replace the pump and then randomly the current one started working. After a few months of it just whirring into action and running for 30/40 minutes without moving any water, one morning it kicked into action and only stayed on for 10 seconds or so and it actually pumped water out.

Since then it's been doing the same every day or so and actually appears to be working. Have no idea why it suddenly started working, as I'd played around with the hose position before with no change - and we'd done nothing to it just before it started working.

Either way for now it is doing the job its meant to, so for now all good...
