Approx price please

[Bangers123]

The house we're buying has a 5 year old Worcester Greenstar Indirect Mains Fed Hot Water System boiler in the kitchen with a hot water tank in one bedroom. (small 4 bed semi)

To save space i would like to remove the hotwater tank and exiting boiler and have a combi boiler installed in the loft.

The new combi will then be connected to the existing central heating system and new pipework to the hot taps supplied.

Could someone please give a rough idea in cost to supply and fit the new boiler and disconnect the old system?

Thanks

combos are not a good choice for anything other than one bedroom flats...

you can get away with it if you are a showerer and you only have one bathroom...

We only have the one bathroom. The three bed house we have now has a combo and i really need the extra space in the bedroom of the new house where the hot tank is.

If you put the combi in the loft you will be waiting 5 minutes for hot water at the sink.

Has the boiler installer measured the dynamic flow rate of the mains supply?

Hi Tony

I've not signed the contracts on the house yet, im just working out an approx budget for the works that needs doing.

When most houses cost £300,000 upwards the cost of new boiler/bathroom/kitchens pale into insignificance!

Its always difficult to give estimates without a survey. 2.5-3K should be a rough ball park to give you an idea. Much will depend on the particular layout. A complicated gas run, difficult flue arrangement and awkward condense drain could all add up to a higher cost.

As Agile has implied, if you have insufficient pressure and flow on the mains supply, you will have poor hot water performance.

The idea that a combi is only good for a 1 bed flat is nonsense and with a bit of thought into pipe routes, delivery of hot water can be reasonably quick.

2k, oh your in Surrey 3k

 

[Elkato531]

No Blakie8. The OP wanted a ball park figure to allow him to budget. Without viewing, an accurate estimate is impossible. Best to give a realistic figure for a decent job with quality materials then there is less of a chance of a nasty surprise.

Thank you, that's helpful

Contradiction?

 

[Elkato531]

Can't see the contradiction Blakie. The OP seems to have understood and is happy with the answer.

An alternative solution would be to retain the existing boiler and install an unvented cylinder in the loft.

Which ever way you do it, it is essential that the incoming cold water flow rate and dynamic pressure is measured to make sure it is adequate. If it isn't, baths will takes a long time to fill and you will not be able to use more than one outlet (hot or cold) at the same time.
