I have flow4 last Wed and no reply yet, but I'm getting more quotes too to get a better idea and comparison too. Just wondered whether anyone out there had any advice. Thanks so much for yours, I'm learning.
I think so! I'd guess that's where the extra cost lies then - unvented tanks are more expensive than normal ones, you need special pressure relief valves, and you'll probably need a bigger - and therefore more expensive- boiler than normal. I'm not a plumber though, and you need to talk to one! Can you just ask the guy who gave you the quote?!
It's to do with the pressure. We had an electric shower but the pressure was terrible. Then we had a pump ( v noisy) installed to add pressure. Now we want it done properly. I think it's a pressurised tank were looking at. Hope that makes sense.
All combis are condensing boilers these days. But my question is about why you need a water tank too? What I'm wondering is whether there are a lot of extra costs associated with replacing and moving the old tank, and perhaps with strengthening the floor of the attic... If your only issue is wanting to run two showers sometimes, then I would have thought that the easier/cheaper option would be to fit one separate electric shower...
You can probably get it a bit cheaper, but it doesn't sound massively high to me. I reckon about £4.5k for the new boiler and system. Moving a replacing a cylinder on top. And if they're moving it a to a loft, they may well need to strengthen the loft floor (to prevent a heavy tank of water dropping through your ceiling!) Is there any reason why you're sticking with a hot water tank, rather than going for a combi boiler?
Some trades people are happy for you to source the materials.
I'm having a house rewired at present and the electrician gave me a list of his wholesalers part prices. I could beat them significantly for some things like the GU10 fire rated fittings I could get from DIY outlets at less than half the price and by negotiation from electrical wholesalers for about 30% of the price.
I'd definitely get a second quote but also go back and ask for a breakdown and if you could do the major item sourcing if you're up for it.
We're planning a lot of work on our house over the next year. First thing.....boring stuff, we need a new boiler and want a bigger hot water cylinder. We have had a quote for;
A new system boiler New controls etc Replacing approx 7 old radiators Removal and replacement of the old water cylinder, relocating it to the loft, it's a big one Removing an old water tank in loft
The plumber said it would be approx 3 days, and two of them on one day. The quote was £6500!!!!! Seems huge....I looked at the cost of the cylinder and boiler online and they cast about £1500 I'm going to get other quotes but wanted to use this guy as the builder who may do our building work recommended him and they work well together . What do you think?
