Quote to replace boiler with combi

trippy

£4,700 to replace our convential boiler for a Worcester condensing combi boiler, wireless conrols, power flush and to replace gas pipes for bigger ones (or other way round). He said £1,000 of that was for the flush. Is this a good price? We're east Lancs. Thanks.

It'd difficult to say with out seeing the job but £1000 for a flush seems excessive. Expect to pay half that for an average size house.

I think we counted 13 rads. It's a 4bed house.

Did they say which model of WB Combi? How many bathrooms/showers do you have?

trippy

No, he didn't mention a model. We have 2 bathrooms/showers and another toilet downstairs.

I'd re-think about getting a combi for your needs if I were you.

Rubbish! A powerful combi is fine. I have a 4 bed, 3 bath house & the Vailant ecoTEC 937 has come highly recommended. It is £1,100 for the cost of the boiler but it is big and ugly so you will need someone hidden to store it. Mine is going in my loft:

Once you have had a combi, you can never go back to hot water storage tanks. They truly are the devil's spawn!!

As a guide, our plumber charges £250/day and he's fantastic. Think the price for the flush sounds excessive too, but I'm no expert.

Combis are fab - just make sure you're getting the most energy efficient one you can. Saves on bills and helps your home energy rating if you ever come to sell.

Rubbish? You obviously don't know what you're on about the vaillant 937 has a water storage tank in it:rolleyes:. It is not a standard Combi boiler!! Why do you think it's so much bigger??

An unvented system is much better. Better showers, no danger of losing pressure if some one opens a tap or flushes the toilet. I hope you have an electric shower if you get a combi. If it breaks down you are left with no heating OR hot water.

Why are they the 'Devils Spawn'?

Combi boilers have their place and may suit some people but some plumbers only fit them because they're easier and cheaper to install.

Every CORGI I know (myself included) would not have a combi in their home. That tells me something.

Good evening: My OH (CORGI) finds that the majority of his customers are asking to convert to a combi (the Vaillant Ecotec Plus 831 and 837 are both popular choices) and he advises potential clients about suitability/possible issues either way. I wouldn't agree that a condensing combi is cheaper and easier to install when you are converting a regular boiler/BBU with HWC and need to relocate the appliance and sometimes have to run the flue through the roof, run condensate to an appropriate outlet, upsize the gas supply and provide a fused switch.
BTW, we have always had combis in our properties (we prefer instantaneous DHW, good flow rate for showers, the reduction in utility bills and the extra space).

All of which has to be done regardless of which type of boiler you install. I was referring to the extra pumps, valves, cylinders, electrics etc needed for a regular or system boiler.

Different strokes for different folks. I am sure you find a combi to be satisfactory for your situation. It just makes me laugh that so many people think a combi is THE solution to all heating set-ups.
