Combi Bolier Install

blueseyeshighlander

Hi, Just had a quote to replace an exisitng combi boiler, £2500 - £3000. Seems very expensive since a bolier would cost around £1000 and all the connection are aleady in place from the old bolier. Anyone had a combi replaced recently?

That sounds quite reasonable. You must remember you can only get a corgi registered engineer to fit your new boiler. They have to pay a lot of money and time to train and get up to certification level. They will also have to asses what system you have, how the new boiler will fit, the gas supply, run commissioning tests once fitted etc etc. Its not just a case of buy a boiler and an hours work later its fitted. They may want to replace some pipes/radiators if they are old and cruded up etc...

If you are not happy with the quote get at least three more. Dont go with the cheapest.

Is the boiler broke beyond repair? It may be cheaper to get it fixed if you can.

Sounds like a BG estimate,(Quite
Reasonable?) even if the boiler is £1000, you only talking about 2 men-@4hours labour 8 hours total, so £2000 for labour equates to £250 PH, is that how much plumbers earn?
Still with all the "Corgi" regs theyve got you by the short & Curleys!:mad::mad:

I had a whole new system installed 2 months ago - Worcester Bosch 28i combi, 8 radiators, towell rail, and all the pipework for £2700.

So that quote sounds way high to me :eek:

I have just had a Worcester Bosch 42i combi installed. In total I paid £3650 - this included the boiler, six new radiators, relocation of gas pipe, replacement of some old pipes, and removal of all the equipment from my old pressurised system. I think it depends where you live as to how much the labour costs -corgi registered engineers seem to be able to charge you what they want unfortunately.

No problem. You'll be getting at least three quotes anyway, so you'll soon see if it's out of line, surely?

I had a Worcester Bosch 30CDi Combi installed in March 07, for £2,400. Just boiler, no rads and no major re-plumbing of any pipework. They did do some flushing thing that they reckoned would cost £350 if bought separately but I ignored that "benefit".

Whilst it felt high (like you, I worked out the cost of the boiler alone was about £1,000 so what was the other £1,500 for!!), I did get 5 quotes (cheapest was £2,200) from professional companies and one "family friend" who would have done it for about £1,800 to £2,200 (final costs after job completed - and no flushing thingy included!).

Like the others, I recommend you get several quotes and go for the company you feel comfortable with, which won't necessarily be the cheapest.

Make sure you get them to quote using the same boiler spec, so that the prices are like for like, or be aware of the price differential so that if one is cheaper, is it only down to the cheaper boiler etc.

In these days of condensing boilers with heat exchangers like corrugated cardboard, the existing system should be thoroughly flushed until there is no "crud" left in the system that could partly block the heat exchanger.

You could find the heat exchanger burning out on you if it gets partly blocked.

Ask your potential installer how they intend to deal with the existing system.
"Which?" found that many installers would just take a chance.

There is a lot of muttering about condensing boilers only being "good" for 10 years service - we will see. (I had an old cast iron 65% efficient Potterton that banged on for over 30 years, without even being serviced).

Just had a quote of £1700 plus vat for replacement Boiler.

Breakdown is

Worcester 30 Greenstar £925
Powerflush £300 (possibly not necessary, but invalidates part of your warranty without it)
Labour £325
Other bits £150

Hi Aardvark,

I will be needing a heating replacement soon BUT in the mean time I will have had my cavities filled, replaced the single glazing with double glazing and upped the loft insulation to 11 inches.

Is there a reasonably straightforward textbook you could recommend called something like "The complete idiot's guide to heat loss calculations" or a web site I could consult.

I did come across a book called "The home Energy Diet" but it was written for Americans in Imperial type units.

Cheers,

Mary.

Good afternoon: Check out the Energy Saving Trust's Whole House Boiler sizing calculator... http://www.energysavingtrust.org.uk/housingbuildings/calculators/boilersizing/

Also take a look at their 'Best Practice' Gas Heating guide for specifiers and installers http://www.energysavingtrust.org.uk/uploads/documents/housingbuildings/ce30.pdf ....an excellent website!
