I know it would be easier to call the local company and see how much but this is so far just a rough guess at replacing a 20 year old one that "still works" with fuel efficiency in mind.

Anyone had one fitted recently or work in the trade. As a guide its a 3 bedroom house with central heating, 7 Rads in all.

There is a big old copper storage cylinder/immersion heater as part of the system that probably has a decent scrap value.

Anyway can anyone give a rough figure to fitting without me having to endure quotes from gas fitters and hours looking up makes and models of combi-boilers.

The outlay cost might not justify the savings in the time frame we are looking at.


I can get a free call out consultation from Bgas +400 quid trade in for the old but i CBA to sit 3h with a salesman if he is gonna quote some astronomical £5k figure.

Can it be done for under £1500 all in. Im guessing....
 
Hey bud, was in similar position as you, had BG in £5200!

Spoke to local Worcester accredited tradesman got it all in for £2350.

That was relocation of boiler from downstairs to up + new rads.
 
I would suggest £1500 is a little on the low side. The GFs parents paid about £3k for a similar job, although they didn't shop around.

I paid £1600 to replace a combi boiler for another in the same location (Worcester 28CDI compact).

The manufacturers will require a chemical or power flush to get the guarantee, depending on what you choose it can add quite a lot to the cost. It also makes sense to add in a magnetic filter at the same time. Apparently older boilers tended to be plumbed in using 15mm sized gas supplies, the standard is now 22mm and if they have to change that over it will add quite a lot to the total as well.
 
Had a new bolier fitted in February by a local accredited WB installer. Had a Greenstar 38CDI installed which is a bigger boiler than you woul require, cost me £2300
 
3 bed house here, 8 rads. Ours was £3k about 5 years ago, going from a similar setup to yourself. Our boiler is a Worcester Bosch Greenstar 30 CDI.
 
If I was renovating the house I would do this, but if it was purely to save money I wouldn't bother. I'd spend the thousands on something else if the current system is not causing any problems.

Would take years for it to pay for itself
 
Interesting comments above as mulling this for a 4 bed semi I am purchasing. Boiler is very old.
 
Anywhere from 2200-3000 for a new boiler installation including the boiler itself.

Best to get an independent to do it rather than BG as they charge through the roof for the same installation.

It always seems like you're paying a lot of money but I hope it is worth it in the end with no breakdowns and lower gas bills.
 
Had an old back boiler and immersion heater/hot water tank ripped out and a combi installed last November by a family friend, was £1600 all in.

Would imagine it would be around a grand dearer not to have 'mates rates'.
 
It depends what you are using it for. I prefer my combi to an old boiler and tank arrangement because the hot water never runs out. It also heats the rads more quickly than the standard boiler in my mums similar sized house.

We've had combi boilers for the last... 6 properties we have lived in, and now have a hot water tank and separate gas boiler.

Combi's are great in a flat, where 1 person lives, and you never have more than 1 hot tap on.

Move somewhere when that isn't the case, hot water tank and boiler is the way forward. Its also instantly hot, and would take the hot tap on full blast for 20-30 minutes until we ran out of hot water. I can fill the bath to the top with our hot water tank and its still hot coming out of the tap. If yours aren't, somethings wrong or your cylinder is tiny.

I would keep an old reliable boiler over a new combi, but leaving some money aside.

Totally this, you will never see the costs back before the modern boiler needs replacing again and it's much more likely to go wrong they are complicated and on the whole terribly built and engineered!
 
I agree as above, I would rather keep an old 1980s back boiler/hot water tank system over a modern boiler as it will take a lifetime to see any return on the savings.

I would only change the boiler if you were changing fuel type.
 
I posed the same question to a Worcester and valiant installer when he came to service our boiler last month. Price was 2k for 4 bed semi with 9 rads.
