Stove Fan wrote: » No it's what I stated, I'm sure Irish regs are similar to UK. You only need permanent ventilation on stoves under 5kw if your home is newish and has an air permeability of less than 5.0m3/h.m2. A stove rated under 5kw installed in a drafty pre 2008 home needs no additional ventilation. For any stove in a drafty homes you need a vent of 550sq mm for every KW over 5kw. For a stove rated at any kw output in a home built from 2008 onwards or thats also very airtight you need 550sqmm for every kw of rated output.

Stove Fan wrote: » Hi, ideally a minimum flue height should be 4.5 metres without obstructions. In your case adding an extra metre of twinwall may help. You can also buy guy wires to support the flue above the roof. To be honest though raising the flue a metre and adding a H cowel on the top would probably cure the downdraft. A H cowel is around £100 and twinwall metre around £75. Labour about a few hours max. Also you state that opening the door/window stops the stove smoking. In this case also make sure the room has a sufficient air vent in the wall to bring in combustion air. You should have so much fixed ventilation depending on air tightness of property. For older homes ie less airtight you should have an air vent of 550 sq mm per kw rated over 5kw. In a modern newish airtight home 550sq mm per kw of the stoves rated output. Please install a carbon monoxide alarm and ideally dont use the stove until the faults are fixed. Stove Fan:)

The stove was fitted using an outlet pipe and flue comes out of the wall at the back and just about clears the height of the extension. The flue doesnt however clear the height of the front dormer section of the house. The stove works fine most of the time but when the wind is blowing from a north / north easterly direction the stove smokes unless we leave a window open inside. Quite often as well the smoke blows downwards outside. Is the outside flue not high enough? I am worried that if we add much more it may not be stable. Would it be expensive to add another metre to it?

SmithySeller wrote: » Its a new house, the insulation upstairs is excellent and retains heat pretty well. Its more the design that makes the sunroom (our main TV room) difficult to heat. I have a gas stove that is 3kw and electric that is also 3kw and when both are running they heat the room just fine. But its not sustainable to keep them running through the whole winter. I assume you mean 9/11kw nominal output?
SmithySeller wrote: » Hi Stove Fan, thanks for your advice. I have decided to change tack, and Im considering placing the stove on the far side, on the opposite side to each valley and opposite the sliding doors. This way the flue can have a straight climb of at least 4metres internally before reaching the wooden vaulted ceiling. Out of interest if you look at the photos again you will see a Gallery upstairs (great for heat loss ) this has about 10 metres squared of floor space and three bedrooms totalling about another 35 square metres. The stairs from the hall also leads up to the Gallery on the far side. The sunroom where the stove will be placed is about 4.5x4.5x4.8, given the heat loss through the Gallery what output stove do you think I should go for? I guess I might as well try heat the bedrooms while Im at it given all the heat is going up there anyhow. And would a convection based stove be better suited? Any recommendations? Ive attached a couple more photos as reminder, stove would placed about three feet to the right of the middle of the long couch, and thanks again
Stove Fan wrote: » Hi, having looked at the pictures and clearance requirements I personally think the stove would have to come out further to clear the timber door/window and in my opinion it's just too tight a space and may look a bit odd being brought forward. Theoretically it's possible as the stove should be 200mm away but I always air on the side of caution as some new owner may fit curtains/blinds to the window and not realise. I would certainly imagine this stove has a heat shield to help with being installed into a tight space. Could the stove go where the oil filled rad is, or somewhere else in this room? The position where the gas heater is the flue would be very near in line with the roof valley. I personally feel the stove would be better placed and flued out the other side of the ridge to the right of the valley. That particular manufacturers state 1.5metres of flue can run above the roof unsupported. In your case I would run the flue internal for neatness using the appropriate supports etc. There would be no problem with going through the wood ceiling. There would be a decorative steel plate fitted either square or circular as the wood around the pipe has to be cut away to the recommended clearance, this plate is a decorative cover. No idea on cost but say 100 euro a metre for flue plus bends. Stove Fan:)
Ludi wrote: » Hi Stove Fan Many thanks for your reply. All your time must be spent replying to all the queries. We have an F&E Tank in the attic so presume the central heating is open vented. House was insulated last year in both cavity walls and attic. Is it possible to run both OFCH and boiler stove at the same time? I know we have a single coil hot tank, so this would need to be replaced with a double coil
Stove Fan wrote: » Hi based on 11 radiators and heating the hot water you need a stove with a 15 kw output boiler. Your sitting room size depending on insulation requires anything from 3-5kw to heat this room. I'm guessing your bungalow has reasonable insulation as the double rad in the sitting room has an output of around 2.5kw. This rad would be switched off as the stove would heat this space. I would say the Aarrow EB12HE inset might be a possible providing some of the rads had thermostatic rad valves fitted and were not all on full. The EB12HE stove produces max 12kw to water and 5kw to the room. You would leave the door open to other room(s) to let any excess heat escape. Your oil system would need to be an open vented system and not a sealed/pressurised system. A plumber could check this for you as most boiler stoves need to be installed on an open vented system.

We are looking into installing an inset boiler stove in our sitting room which will heat our water and 12 radiators.

So long as everything it passes through is non combustible, ie solid masonry, then your fine in single walled pipe. If on the other hand it was going through the wall to a new twinwall chimney then the twinwall should start inside the building and then go through the wall. Ie singlewall pipe from stove max 1.5metre then 45 degree bend with sootdoor, then into twinwall insulated flue through wall and rest of the flue run. Stove Fan:)

Just a confirmation of a question - where the flue pipe enters the wall in my sitting room, is it ok for this to be just regular 5'' flue pipe - doesn't need to be twin wall or anything special? Thanks!

Any help appreciated..
Stove Fan wrote: » Hi, so long as the wall is solid and isn't drylined or has wallpaper or gloss paint it will be fine as is. It may crack the plaster due to the heat from the stove but you could if you wanted clad the wall behind with a vermiculite board and emulsion it in the same colour as the wall. Stove Fan:)
kali23 wrote: » Hi Stove Fan, Thanks again for all that advice, the stove they were trying to sell me was a Hestia. I hadn't heard of it before and so I didn't contact them after that. He didn't specify the problems with the aarow and to be honest I didn't ask him to once I heard he didn't stock them. I am concerned that I was strongly advised to put in the Charnwood and obviously that won't be sufficient to heat my house. I was told that their spec was based on burning wood and I would probably get more Kw's out of the boiler burning turf/briquettes/coal & basically because these other customers were able to heat roughly the same number of rads that I would too. I find it unbelievable that I could be told this information especially as I am hoping to heat my house solely by this boiler! Sorry, can I just ask is the EB20 7kw to room? If so does that mean it has a boiler of 13kw? Is the EB25 on sale yet? On their website it says 'coming soon.'
kali23 wrote: » The lady in the shop told me her sister has the same stove and heats 16 rads and she has another customer who heats 22 rads from the Charnwood 16b. The single rads in our house will be 9 1200x500 5 1400-1600x500 And one small rad in the hot press. I haven't seen the aarrow but I did contact one of the boiler stove companies whose link u posted and even though they have it listed on their website they told me they stopped stocking that stove as it was too troublesome??!!
