help- boiler question- replacing boiler without replacing everything else?

Hello all,
Another boiler question on this thread- I have searched to see if this question is answered elsewhere, but can't find anything so...
Our system is old (~27 years) and the heat exchanger in the boiler is gone, so we need a new boiler.
I got a quote from a CORGI engineer (this morning at 9am on a Sunday!!) and he reckons that current regs require a new system- our tank is out of date and it would be illegal to fit a new boiler in without updating the tank etc due to energy conservation regulations.
What he is proposing is- rip out the tank upstairs, install a combi boiler, change the vent supplies and change the gas inlet pipe. He also says that as our shower (electric shower) runs from the tank, we would need to replace the shower
Is this correct? This makes the job a £3k job instead of a £1k job.
I am based on Oxford. If anyone has any recommendations for CORGI engineers in the area I would appreciate it,
Thanks for any responses in advance,
Ciara

    this will help you with info.
    he doesnt have to install a combi but it does make sense in most cases.
    most showers have to be changed with a combi.
    here in the NW you could get it done for about 1500 quid. so 3k is prob the going rate in oxfordshire.
    check the corgi site for installers in your area. it has search by postcodes.

  • Hi

    You do not need to replace your cylinder.
    Having said that I would recommend that you do. Your old cylinder will be scaled up and may well have minimal insulation on it.A new one will be Part L compliant with a larger heating coil to give you 20 minute reheat time and greater insulation.

    I personally ask the customer what THEY want not what I want them to have.
    If you want a combi I will give the pros and cons
    It sounds as though you are happy with the system as it is (except it doesn't work) and money is the governing factor usually, so there is no reason not to replace the boiler, cylinder and, if you haven't already got, thermostatic rad valves and full controls.

    P.S. Do not proceed without getting at least 3 written, full specification quotes (not estimates) from CORGIs recommended to you by a source you trust.

    Thanks to both replies- I have a second guy coming in later today to give me a second quote, and a third on Wednesday so I shall see what they say
    I am starting to resign myself to paying out quite a bit!

    You really need to decide how YOU want the system to work and them tell them what to quote for. When we renewed ours almost all the people we got in immediately defaulted to quoting for a combi. My own experiences coupled with potential shower replacement costs suggested this was inappropriate for a place with 2 bathrooms. In the end we went to a system boiler with a new HW storage tank. This gave us lots of volume good flow rates and fast HW recharge times..........worked well for us.

    We replaced just the boiler for a non-combi condensing one. Though a British Gas sales guy did try fool me into replacing the cylinder too by tapping our hot water cylinder and saying "that needs replacing as i can hear chalk in it"..3 other corgi installers had already told me there was nothing wrong with it! So always get at least 3 quotes - you'll soon find out who is telling the truth and who isnt!
    At the same time we had new programmer and thermostat plus a couple of TRVs (£30 a time) fitted and an automatic bypass-valve to bring the system upto date - that all came in at £1945 a year ago.
