Quotes for Fitting Multi Fuel Stove

femalediyer

Hi all
I am new to here, so please bare with me if I have posted this is in the wrong place or way.
Basically I have been given a brand new, still in crate multi fuel stove. I have started to open up the fireplace to its original size/shape. I have contacted and had out to look, several registered HETAS fitters, some of which will not do the job of fitting and commissioning as its slightly more complex than what I would call a normal (word used very loosely) fit.
I have a chimney stack that runs the whole way through the house right up till just under the ridge tile, there is no outside chimney stack. Therefore I will need a twin walled system with the tall stainless steel pipe fixed to the exterior.
Anyway..... down to the real reason for posting... I have now received three quotations, all to do the same thing, which is to provide the twin wall liner (they all wanted to supply), fit liner, remove and replae ridge tile when complete, fit register plate, install stove, test and issue HETAS certificate. The three costs for exactly the same work are £1013.00, £1500.00 and £2040.00.
After all that, my question is ... do you think that this is too expensive, even using the lowest quote????
Building regulations for this from my local council are £315.00, so that would be saved but even so???
Any thoughts, comments please?????

Please note that this does not include any building works to the chimney and obviously I am supplying my own stove!

The middle and top quote are expensive. The bottom quote is expensive, but this is not the time of year to have a stove installed because everyone has the same idea. Hence prices will be high. I paid a bit more than £1000 but that included supplying and fitting a granite hearth.

Re the twin walled flue: are you talking rigid twin wall all the way through, or the flexible stuff as a liner? Only the rigid twin wall costs a small fortune. We had no chimney in our place, so had a stainless steel twin walled system put through our two story home. The twin walled flue (the good stuff mind) can easily cost £100-£150 per metre. That soons brings the price up......

External SS twinwall wintergirl.

If the fitters are supplying and fitting the chimney system then imho the first quote is too cheap, so could well be using substandard parts, the second quote I would say is about right. The chimney system you would have approx 10M from the stove to the cowel so at £100 + per M the twin wall alone could well get to a grand + fitting costs.
The third quote again not far off the mark depending what system they are using, imho not ott.

Theres another option available to you : to see if you can make things cheaper get some quotes off builders and chimney sweeps to extend the stack through the roof and put a new pot on, then install a 904/904 flexable liner ?

My prices were just for lining a chimney, I hadn't noticed you said external pipework.

Thanks muckybutt for your response. Hope you dont mind but can I pick your brain somemore!
You say that the first quote is too cheap and mention substandard parts, what would you class as substandard and how will I know??..
Unfortuantely, I dont have the option to have the stacks built back through at this time, so hence why I have gone with this option.
The cheaper quote is to install multi fuel liner with reg plate and adapter to vitreous enamel flue pipe. Exit top of chimney and connect to twin wall flue pipe etc.
I am rather concerned now how to know which are the best parts!

Leif ...This might sound daft but I didnt really think that the time of year would make that much difference but I suppose that is a fair point...

muckybutt

Ahhh now the cheaper price make sence !

So the cheaper price they will install the stove into the existing chimney, fit a register plate, then line the existing chimney with vit enamelled pipe, cap that in the loft and go out through the loft to the outside with a ss twin wall liner ?

Sounds a weird way of doing it to be honest and one I wouldnt go with personally, the vit enamelled pipe / liner is what I wouldnt go for throughout the chimney.

PM Hethmar http://forums.moneysavingexpert.com/member.php?u=53290 he is a registered fitter and could advise a better way of doing it.

Thanks once again Muckybutt...
The middle quote I think is taking a slightly difference approach, that is quoting for usig a 904 flexible flue liner with a twin wall chinmey extension with lead ridge flashing....
Does that sound a better option??
Can I ask why you dont think that vit enamelled pipe would be a good option??
I will pm Hethmar as you suggest but thank you, its good to talk to someone who knows what they are talking about!
One last question (making the most of having your attention) what are your thoughts on putting a panel of calcium silicate at the back of the stove. The back wall of the fireplace is all uneven and it was suggsted that a panel of this was fitted to make it tidy?

I read it that it was going to be stove pipe from stove through register plate to MA Adaptor, then flexi liner to top of existing stack then twin wall through roof. Single skin flue pipe can not be used beyond the room in which the appliance is in. i.e it can not pass through floors or be used in roof space or pass through internal walls.
Still not to sure what is being proposed.

Edit: posted after femalediyers response so a bit clearer now.

I assume that the two quotes mentioned above are significantly different as they are using two different systems? i.e. vit enamelled and flexible?

w50nky

Would really need to see what each fitter was proposing to compare.
Vit enamelled pipe is used from stove to flexi in most stove installs which use flex liner as it can withstand the higher temps at the stove outlet which protects the liner to some extent. Although it it not mandatory to use enamelled flue pipe at all. You could connect flexi to your stove if you wished but it would look unsightly I think, even if painted.
