Wood Burning Stoves

#1
Calling all rednecks..... I'm looking to put a small wood burner or pot belly stove in a living space of approx. 14x6.5x6.8ft (LxWxH). So some dumbass questions:

1. Would 3kw be suffient in winter? Would 8kw cook me alive?
2. Min. distance between wall and stove?
3. Would a double 90deg. angle in the flu increase heat, aid draw?
4. I've seen steel stoves advertised. How comparable against cast iron?
5. Anyone cooked with these?
6. Purchase for example, Firewarm 4 Stove £199 on Ebay, £350 elsewhere. Do you know of anywhere else that specialise?

Anything else you can think of to assist will be grateful. Thanks.

we have a wood burner, ist a villager "Kitchener", our room is a bit bigger than yours and it is ok, heat wise it realy depends on what you burn as to the heat output if you burn soft wood not very good, oak ok, ash vgood,MDF sweat box!! its a bit of a try and find out. it may be worth getting an expert in as its not that strightforward you need vents to let air in the room, you may need the flue lineing (cost a bit) you may need a multi fuel stove if you want to keep it in overnight, as for cast or steel is all anout looks cast tend to look old, steel look modern

hope this helps

Thanks, great stuff. I'll be burning all sorts of free stuff. Would stray cats and dogs burn OK?

Just check that the property is not subject to a Smoke Control Order under the Clean Air Act 1993 (many properties, particulalry in urban areas, are). It controls what you can/cannot put up a chimney.

If the property is subject to a Smoke Control Order, you can still go ahead with your plans, but you must either have a approved appliance, or burn approved smokeless fuel. Information about these can be found at: http://www.uksmokecontrolareas.co.uk/

To find out if you're in a Smoke Control Area, contact environmental health at your district council.

Good luck!

1. Would 3kw be suffient in winter?

Likely - your figures worked out at 618 ft³(for the benefit of the young farts 618.8 ft³ = 17.5224 m³) - assuming a heat loss at between 1.5 and 2 (times per hour), to maintain a "constant" heat of 70 degrees will require something around 1800w to maintain this.

Note:

The figure of 1800w is based on some assumptions about the construction, number of party walls, etc. To calculate it properly, you need to detail out the wall types, window, door, type of floor / ceiling construction, temperature of adjacent rooms / voids etc. - Should keep you busy for a few hours Pandaplopper.

In a really bad construction scenario, you could quite easily see the heat loss be up to 60% higher. Either way, your 3kw output should be adequate.


Would 8kw cook me alive?

Quite likely - be aware that the efficency / burn rate and therefore the output of the stove will not always run at 100% - this figure will be based on the manufacturers recommended fuel / burn rates (dry fuel). Realistically, most owners tend to stoke three maybe four times a day (don't be a slave to it) and therefore the outputs rise and fall inline with this.

Ventilation is the key point here, and you will want a constant flow of air available to the stove - again impacts efficient burning.


2. Min. distance between wall and stove?

Construction of wall - how thick (it not you) / heat loss of wall
Check with local building regulations.
Check manufacturers guidelines - depends on design of stove - rough rule of thumb is likely to be 35 - 60cm


3. Would a double 90deg. angle in the flu increase heat, aid draw?

No.

4. I've seen steel stoves advertised. How comparable against cast iron?

Lighter, cheaper, don't last as long.

5. Anyone cooked with these?

Yes. Go and have a look at http://www.aga-ranges.com/cooking/ I am not being blamed for your failures in the kitchen. :)

6. Purchase for example, Firewarm 4 Stove £199 on Ebay, £350 elsewhere. Do you know of anywhere else that specialise?

My folks had a cast iron box in the living room that burnt wood and ran the hot water and central heating. I read the manual - the box was designed to all-but exclude air to force the stove to burn the combustion gasses. I'm not sure I understand the science of it, but it produced a shitload of heat from a few bits of wood. You could nearly touch the glass door and the flames were..............well, not proper, dancing flames :?

I would suggest going to a canal forum and asking some questions there, this post might just make you realise how important correct fitting is:Fire on my boat

Every year there are about 5 fires on narrowboats from improperly fitted solid fuel stoves and about one death due to insufficient ventilation/ carbon monoxide poisoning. Be very careful as there are currently no British or European standards for correct fitment of of a solid fuel stove on a boat or mobile home.

err you'd probably have insurance nightmares with this.
It's already insured.

It may well be insured but if it goes up in flames and you haven't told them you have fitted a log burner then your pride and joy is in effect not insured.
Motorhome insurance with a log burner will be hard to get. Propex heater might be available on e bay cheap. You are better asking the people on the self build motorcaavan club thesequestions. There are people on there who have fitted them.
Yes, good point. I've just asked the question. If it turns out no one will insure then I just won't tell anyone. If my van goes up in flames then I'll take the hit but as long as I have a piece of paper to wave at Mr. Plod that's all that matters to me. I can't go through life worrying about these minor technical matters. :wink:

Chieftiff is on the donegal on this one. Small spaces are the realms of the Morso Squirrel. Output enough not to need extra venting. Google that badboy and it will probably show up on a few Narrow boat websites too. Cast so takes a while to warm up but holds the heat incredibly well. You can get a back box to warm water too. A HETAS approved Engr will be a must if it is in the house, in the back of the Robert Redford who gives a monkeys!
Oh and you get a wicked little Squirrel on the sides to talk about too.

Thanks for that. Checked out the Morso Squirrel. Not cheap is it? The cute little squirrel bit and chatting to it gave me false hope. :wink:

A gas heater would be easier and safer. Is there not already a heater in the motorhome?
You can get a small portable gas heater or stick with a stove. If you go for a stove make sure it is multi and not wood alone, every time you go to a petrol station you can purchase coal and peat on sale.
ask these folk for their words of wisdom.
