What’s your opinion on this BG boiler quote?

Thanks. That’s handy to know about the boiler cut out on the condensate pump. Are they noisy in operation? How much of a fall do you need for a gravity condensate drain and what size pipe can you get away with? I’m sure the one round my Mums house was just a white plastic 22mm pipe. I was hoping that all condensate drain piping would be in the loft but I wouldn’t be too bothered if it came out through the flank wall and round to the soil stack - I’ve seen it done on a house down the road and it wouldn’t bother me if that was the only way but if you look at the photo, you can see where my boiler is fitted on the flank wall and I was hoping to feed it into the soil stack where it passes through the soffit void. I could even get up there myself, remove the roof tiles in that area and make the connection to the stack ready for them to connect up to - hence my question regarding condensate drain size and fall.

I’d run it in the loft to the SVP with as much fall as you can get on it. Condensate pipe should be ok and get it well lagged... also depends if you have a warm or cold loft, is there insulation between the rafters or just the joists?

It’s better than another bit of kit that can pack up IMO. As you say, if it does freeze up you can get to it fairly easy with a hairdryer, but if properly lagged - which can be overdone as it’s not on view, you shouldn’t have a problem. We’ve done loads like that and none reported issues during the Beast from the East - had loads of callouts to others that had external runs though.

BTW: what CCTV cameras are those on your soffits? Any good? I’m looking for a decent product to put up at my gaff.

Thanks. That’s what I’ll try for. Insulation just between the joists. Never had a pipe freeze up in the loft since the boiler was fitted there 26 years ago so should be okay. I suppose if the condensate pipe was clipped to the flank wall I could leave a 6” gap next to the wall uninsulated although having the boiler up there must take a bit of the chill off. I may have to have the new boiler fitted slightly higher than the old one to get a decent fall on it. Does the expansion vessel have to be higher than the boiler? I can’t see why but I think they just fitted the expansion vessel in that position when converting it to a sealed sysyem as that was where the filler/expansion tank was. I think I’ll have an extra filling loop and pressure gauge fitted next to the boiler as well.


The CCTV cameras are only cheapo Swann ones. Came in a kit with 4 cameras and the recorder. Cost around £300 if I remember. Ok. Ish!

Yes, I would, but it’ll affect your price as you’ll need a new flue hole and the old one will need making good... and they’ll need to get up higher from outside.
 
Thanks. I’ll talk to them. I may save a bit by not paying for a pump and if it costs a bit more because of increased labour, it would be worth it in my mind.
 
Well, I’ve received my written quote today from my local installer:

I’m very happy with that except for the condensate pump. I’d rather have gravity take that away so I'll have to get them back to discuss that. I’ve got one 'normal' gravity bog in my house and one pumped one. I’ve had trouble with the macerator three times and don’t have confidence in a pump - it’s just one more thing that can go wrong.

What’s people’s opinions of condensate pumps?

Nice and quiet, as said somewhere else they only run for a few seconds now and then, just make sure it is wired in correctly to stop the boiler as many aren`t :mad:
Some need a quick wet vac out every couple of years (you can do that) ;)
 
Once had a greenstar terminating the condensate into the same waste as a macerator.
The waste choked and the macerator pumped all the shît right back into the boiler.
Case went back on very quickly & it was new boiler time.
First off that`s an incorrect installation using the macerator for condensate water (buggers up rubber components) and secondly pumping waste back to the boiler is not possible UNLESS they joined the condensate pipe to the macerator outlet pipe in which case again an incorrect installation.
Sick n tired of macerators getting blamed for incompetence. :evil:

Keeps you busy though eh JP! ;):whistle:
 
Decisions, decisions! o_O

When they put that EV back on the system, get them to stick a lever valve just before it (upstream) that way it’s simple to drop pressure on the water side if it ever needs recharging... no need to drain water out of the system - just what’s downstream of the lever valve... good idea to remove the valve handle and keep it somewhere nearby though - so that it doesn’t get inadvertently closed - leaving the system with no expansion room :eek::)
 
Hmmm. Just had a quote from a Vaillant approved installer to fit the boiler if I supply it for little more than BG want for just the scaffolding! £680 and that includes all pipe and fittings. They’ll register it so that I get the 7 years guarantee. I can get the boiler and flue for less than a grand so looking like it will cost around the £1,650 mark. Looking favourite at the moment.
