Bought a house... Boiler is about 20 years old and a few of the radiators in the house dont warm properly. Its the system where I have a hot water tank upstairs and a cistern tank In the attic.

I'm wanting to just go over to a combi boiler. Want it moved out of the downstairs toilet and moved into airing cupboard upstairs. Water tank to be taken out.

New radiators to be added throughout. (4 doubles downstairs, 3 singles upstairs and a towel one for the bathroom. Boiler will be a Worchester Bosch 30i combo.

Ive been quoted by two recommended plumbers at about £4.5k. Loads of people have been telling that's way too expensive and shocked beyond doubt at the price. But then again most these people just had a straight swap of a boiler (mine is a different system and a location move)

Has anyone had something similar installed? Am I getting quoted over the odds or is it about the right price?
 
Materials alone would be about £2000 inc boiler, its so hard to tell exactly whats involved i would sugest geting 3 more quotes.
 
Seems cheap to me! I payed around that to re site a boiler and only one new rad. (could have got it around 1k cheaper but I needed it around /before xmas)
 
For the work described that price sounds pretty decent to me the boiler and bit will cost 2k before he starts it is a totally different job to simply swapping an existing combi!
 
I had my old system boiler replaced with a combi about 3 years ago for just under £2,200.

It was moved from the Kitchen to the loft in the process which involved running a new gas supply but no significant work to radiators or the pipes. Luckily Connecting into the existing pipework wasn't too involved, but it was still a two day job.

It wasn't the most expensive boiler (30 kW Ariston), but it did include an extended warranty on the boiler (still only to five years), a Magnetic filter and a wireless programmable room stat plus all of the usual fittings.
 
Depends where you are. My system cost over £15k.

Are they repiping the rest of the house. How big are the Rads just saying they are double doesn't help if they are 8ft long.

How big is the house and how many people live there.
 
I've just paid my plumber almost £2000 for a Worcester boiler, flue, mag filter, couple of rads and the new pipework in the loft where I'm moving the boiler to. Still got the rest of the pipework, and gas pipe, rads, and control to go.
So I don't think your quote is to bad.
 
I'm in the process of completing on a 3 bed end of terrace house with an old boiler and air heating system, I'll be looking at having it all removed and replaced with a combi boiler / radiators and quotes have been around 5 - 7 grand so as the work you are looking at is fairly similar I'd say the price seems ok! A friend of mine had exactly the same done last year and paid 7.5k but he did also have a very impressive digital shower installed at the same time with a few fancy radiators too.

Did you have geothermal installed or something? I am struggling to understand how even a from scratch heating system would come to even half that unless your house is some sort of 10,000sqft monster of a place? :p

Detached Edwardian house over 5000sqft 3 floors complete rip out and re pipe all new rads. Secondary HW circulation Cost was trade too.

Its a bit tidier now and all boxed into its own little room. The pump on the right was about £600 on its own

A new start from scratch would have been cheaper as they wouldn't have had to remove all the old stuff


Boiler room
 
Just had our old heating system pretty much completely ripped out (old hot water tank etc), new combi boiler moved into the garage, new pipework, 10 new rads and a large towel rad installed for £3800. Also included was magnetic filter and wireless programmable thermostat.
 
Surprised that the installer didn't use Vaillant controls for the boilers, allows for better control of the system.

Still sat in the boxes mate. Were doing a complete renovation and still wondering whether to go full Evohome or keep it simple. So the quick and easy fix was a £20 honeywell job.
 
magnetic filters need to be fitted as standard on all new installs iirc.

i don't see the point myself in switching to combi if it's going to cost £4.5K.

what you going to save yearly £50 compared to a more modern system of the same variety you have now? it would take 20+ years to break even and by then it will likely need replacing therefore your not saving anything just paying for it all up front.

unless you have black money to burn and/or looking to increase the value of the home and sell it on i'd stick to the same system that is there just buy something newer and more efficient.

If its a new clean system then the correct amount of inhibitor will suffice.

However having said that. They are cheap as chips and cant do any harm. But having the correct amount of inhibitor would be better
 
A lot of the boiler suppliers will only honour the warranty if you use a magnetic filter.

OP as for your rads not getting warm, it will most definitely be the buildup of crap in them, they'll be half full of that black slurry since your system is so old. If funds are tight and your old boiler works fine, you could always just replace all the rads for now. So easy to fit yourself you'll save thousands.
 
I just went for it in the end. Just under £4500 all in. Was initially Just going for a new boiler in the same place and remove water tank.

The old boiler was a glow worm and very old. It had one of those buttons where you had to spark it to start it up (like a cooker). So decided to remove water tank from upstairs cupboard. Remove boiler from downstairs toilet (it was a very small toilet) and had new boiler in upstairs cupboard.

Dad ended up paying for my radiators as a house 'warming' present. Very happy.... My friend who I've know for 15 years for the first time said 'god its warm in this room'. Normally my houses have been very cold haha
 
Sorry to hijack thread but have a question. Is there any options where you can keep a conventional boiler and hot water cylinder but get rid of the tank in loft. would love to boil the loft for storage.

Wouldn't want a combi as don't want to loose pressure when more than one tap goes on or the bog flushes.
