should all new gas combi boilers be condensing?!

Mr_Proctalgia

As a bit of an aside have any of you any experience of these

I'm moving into a much smaller property and one of these combined with a bit of help from a solar fitting for the water would/could be quite a good money saver.

thanks for all the help people, just get my quote through, £2150 to supply and fit Worchester Greenstar 28i condensing combi boiler and re-position it above the kitchen in the bathroom, and move the supply pipes to a rad (not a big job as the ceiling is down anyway).

Do you think this is reasonable?

A Plumber/Gas fitter friend tells me that he spends much more time repairing the new style condensor boilers than the traditional type. Apparently they are more efficient but the maintenance and reliability is not as good. His advice is to keep the old boiler going for as long as possible.

I have a very old vaillant that is excellent - recently did some replastering in my house and had to remove radiators which compromised the radiator circuit necessitating draining it down. It may interest others, who may be similarly naive to me, that combi boilers will not produce any hot water with the central heating circuit drained down. The boiler pump needs a pressurised central heating circuit to run. I have been without an upstairs toilet and hot water for nearly 2 weeks - thank god for a downstairs toilet and the gym for showers :-)

I've just been quoted £2400 for a similar job

is condensing boiler same as combi boiler?
do u need a hot water tank for either of these?

Condensing and combi boilers are two different animals, but you can get a condensing combi boiler.

A combi aka combination boiler is where the boiler generates both the heating and hot water. For that reason a hot water cylinder and storage tank are not needed.

To save me having to type an essay look here for info on condensing boilers.

Remember you can get a condesning combi boiler as well as a traditional condensing boiler. I don't think you can get condensing back boilers yet.

I have just had back boiler and fire removed. 3 replacement rads down stairs and 4 new ones up stairs and a new condensing combi boiler for £4100. The boiler it self cost about a £1000. This did involve taking up a lot of floor upstairs to lay the pipes.

It took one bloke 3 and half days to fit. But he said he was spoilt as we had cleared spaces for him to work and had little in the way of stuff up stairs. Said that they normally have to add about 1 and half days on, just for moving stuff like beds etc. As people don't think about making a clear space for them to work.

The ones I read about cost about £3k just for the unit and have to be on a outside wall and the size of a washing machine.

So you need to work out how quickly you will get payback and if you have the space.
