Hi

I live in a Defra smokeless area and looking to buy a woodburning stove for the ground floor (No chimney) my questions are threefold
a) how high up on the external pipe need to be
b) is anyone HETAs registered who would give me a price to fit it
c) has anyone had it fitted and what were the types of costs they were coming out with?

cheers oh forum oracle

A - High enough that the top gets a good clean passing airflow.

B - Make friends with your local chimney specialist. In Lancashire this would be Ian at Acorn Chimneys in Burnley, a top bloke altogether but as with all chimney blokes he is booked up months in advance.

C - Not had an exterior flue fitted but internal twinwall stainless flue is now costing between £60 and £100 a metre not including fitting.

If you're in a smokeless zone it's not just length of chimney, it's type of stove. Clearview are ok for smokeless zones and will answer the other questions if you call them.

They have divided the country up and people are not supposed to break boundaries of their areas, but some do, so it's worth ringing around. You can usually get £200 ish off list.

We've had 2 fitted - one recent, one some time back. Both were lining existing chimneys. The more recent cost c. £2500 incl. the stove (pioneer 400)

I'd second RR's advice.

The flue may well cost more than the stove.

In reply to Fluvial: Woodburning stoves are the nees bees for sure, fitted one myself through the plastic conservatory roof , its water tight and works really well. Got free supply of decent wood through a sydicate i shoot with, up yours British Gas. Take into account the cost of everything before deciding to fit as its a big outlay for three months in winter. Will see the benefit for years after.

£300 for the stove
£280 for the flue liner
£30-ish for the chimney cowl
£250 for the slate hearth
£100 for heatproof plaster to line the fireplace (it wasn't heatproof though)
£40 for an oak mantelpiece
£20 for a ventilation duct
£20 for a carbon monoxide detector
£105 for Hetas cert from local building control

We did all of the research ourselves to make sure we got the stove properly positioned in the fireplace, plus getting the right size flue and ventilation duct (it's all on the internet and hardly rocket science).

We have a good friend who is a builder and he didn't charge much for his time - about 2 days labour?

The certificatin was a 2-stage process. First the inspector comes out to check you've got a decent chimney/ventilation. Once it's all fitted, he check the measurements then does a smoke test.

Pretty straightforward. Most/all of our local chimney sweeps offer a stove fitting service. If they're HETAS registered, then I think they can sign off the installatin themselves (might be wrong here).

In reply to Fluvial: I've been quoted £1250 - £1500 just for fitting the flue, nothng else, no tyding up o fbrickwork or stove...that seemed extortionate and I havent bothered with it! I'd always go HETAS though, saves having to go through Building Control and pay them as well

In reply to Fluvial: I have just finished installing my own including getting the official Building Control sign off... It cost me £500 for the stove (a Charnwood), £130 for the building control sign off, £250 for the flue liner and associated parts, and around £200 in materials and labour to build the hearth and skim the fireplace with high temp mortar. I was quoted £1200 for the installation by a Hetas engineer (not including the stove or hearth etc).

Look up part J of the building regs - they are really not that hard, and then at least you will know what you need when asking for quotes.... http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADJ_2010.pdf

Re height of flue, It's something like 2.5 feet above anything 8 foot horizontally away from it. But I can't remember how far it has to be from windows.

I can only speak from Germany but it´s all much the same really. The chimney flue has to be 1m above the roof and normally ca 5m is about as short as you can get away with without fitting an auxiliary fan. The flue is about £800, connection into the house £50-100. Hole through the wall £250. Lift to fit the flue £150. Flue installation maybe £250 (depends on at the roof eaves or ridge).
Depending on your house you may need an external air supply and/or an extractor fan/window open interlock.

Wood stoves are brilliant, but...

If you are doing it to save money on heating, you will not. Wood burning stoves are more of a lifestyle thing - which needs to include enjoyment of chopping/splitting/stacking logs and keeping them for 2 years to dry. (or paying someone else to). Logs are more expensive than gas or oil, and still demand hard work to move and store them even if you buy them.

The flue height will be dependent and related to proximity to walls, windows, ridge height and is defined in the building regs. - see the planning portal.

I'd recommend a decent quality stove like Morso or Clearview.

I had a Morso (Defra approved) fitted last year at a cost of £2500 for stove, liner, cowl, register plate, vermiculite insulation, lintel, installation, and HETAS cert and C0 alarm. This did not include modifying chimney chamber, new concrete hearth, plastering.

In a very small stove I burn about a wheelbarrow of logs in a day. One log 14" long x 6" diameter burn through in about 40-60mins. So you need to bank on having a large covered wood store.

Also you could end up spending on chainsaws, axes, protective gear, chains/oil/petrol, trailer for collecting logs etc.

Not if you can source them for free

If you get a stove less than 5kW - you won't have to get a drafty ventilation duct/brick fitted.

We got a Morso badger - I like it - we're still trying to learn how to control it

Doesn't that depend on the size of the room and various other things like the floor type.

It helps to have the flue pipe thermometer as essentially tells you when you are over-fueling or your fire is too cold for good combustion!
