Central Heating overhaul (new boiler)

Locoblade

Hi All

Our current hot water system has a (poorly lagged) open vent water cylinder in the airing cupboard, a cold water feed/expansion tank in the loft, all heated by an old 70s style back boiler.

We want to get rid of the back boiler and put a new one into the extension we're building. We don't want a combi and probably don't have enough water pressure/flowrate to go with a Megaflow unvented system, so we asked for a quote from a local heating company to do the following, keeping the existing open vent setup:

• Chemical flush the existing 10 rad system (they don't offer powerflush)
• Rip out old boiler
• Replace existing DHW cylinder with modern equivalent in same location
• Install new Ferroli Optimax boiler in extension (HE 18 OV I think)
• Fit basic Honeywell Y Plan pack controls/valve
• Connect everything up and commision boiler.

For this we've been quoted £3760 including VAT (South East England)

I don't believe that includes TRVs for the rads, and if I wanted a Vaillant boiler it would be "about £300 more".

The boiler appears to cost about £550 and the controls about £100, therefore a Id conservatively estimate parts will be no more than £1k, so although I may be wrong, around £2.5k of labour seems a little expensive to me given the apparent simplicity of the install, using virtually all of the existing plumbing?

Ferroli.......RUN AWAY!!!!!!

Care to expand?
I wasn't intending on going with that anyway, they'll fit a Vaillant etc if that's what I want, I just want to get an idea on the price.

If they're suggesting a Ferroli boiler it sounds like they're trying to make as much from the job as they can with little outlay. Add to that the fact that they can't do a powerflush (which is part of a new install) which also saves them a good few hours!

Have to say it sounds well over priced to me judging by the info you've given.
