Wood Burners

94 posts in this topic

We had a multifuel fire fitted 3 years ago and it was the best thing we have done, the house was toasty all winter and the fuel bills were reduced quite a bit.

the price of logs these days is crazy, really reflects how much woodland has been cut down wantonly in the past.

We were lucky having our own woodland to manage and this always kept us in 'free' wood.

I remember paying about 25 quid a tonne, now (depending on where you live) it is as much as 140 a tonne but it still works out cheaper by 1/2 than using domestic oil or kerosene.

Don't know if any of you have heard this before but I memorised it when I was a kid from helping out this dude who used to deliver logs.

Beech wood fires are bright and clear,
If the logs are kept a year,

Chestnut's only good, they say,
If for long it's laid away.

Birch and fir logs burn too fast,
Blaze up bright and do not last.
Elm wood burns like churchyard mould,
Even the very flames are cold.
Poplar gives a bitter smoke,
Fills you eyes and makes you choke.
Apple wood will scent your room,
With an incense like perfume.
Oak and maple, if dry and old,
Keep away the winter cold.
But ash wood wet and ash wood dry,
A king shall warm his slippers by!

Yes it certainly helps to know what you are buying as you can get ripped for wet wood and resin filled pine. We pay up to £50 a ton for the odd load but we mainly get ours for free its just the work to cut load then restack it.

Its the resin filled pine that really funk up a woodburner and chimney/flue. Its this that causes chimney fires. Costs a fortune to get it removed by a chimney sweep too. Really not worth the risk burning it unless its the odd log in a mixed load of hardwood and you want a quick flash of heat when you light the fire...

£50 a tonne is cheap mate. I remember laughing at the influx of city folk into my village who get ripped off for unseasoned wet logs and crappy pine and then complaining about their houses being cold in winter, while the locals would look sheepish and snicker in the pub ;)

Just finished my latest burner its made out of 2 gas cylinders and some other bits I had kicking around I ripped the heat exchanger out of a condensing boiler and turned the condenser in to a heat exchanger so it makes huge amounts of hot water its even got a hot plate on the top so I can boil my kettle and run my still planning to heat the whole workshop with this one I have got a few radiators to hook up to it and a hot water cylinder for lots of lovely free hot water

It tracks the price of other fuel gas/oil goes up the cost of wood goes up.

From what i can gather the designs are flexible vince , but certain things have to be taken into account & some parts need renewing such as the internal chimney. :unsure:

i think that the minimum recommended size for the duct is 4 inch.

and things like ease of cleaning / ash removal need to be thought about.

i traded logs for cheese, im happy ;)

rocket stoves can be made to pretty much any size, youve just got to scale it down, some guy made one on the youtube somewhere that runs off matches, about the same size as a couple of golfballs, have a look at the portable rocket stoves, theres a guy making them that looks like wooden chests, you going to fit a mass? all you need is a 4 inch hole in the registry and you can use flexi pipe to go to that

Hi I will take some picks of the wood burner tomorrow

I made it out of a large gas tank that came out my old 4x4 that I gas converted 12 years ago and the gas tank had got to rusty for road use

2 normal gas cylinders and some other bits and bobs that I had in the scrap metal bin ..

the heat exchangers came from a knackerd condensing boiler I payd 99p for off ebay picked up 5 miles from the house

central heating pump £3.00 local boot sale and a load of used copper pipe I picked up off freecycle with 5 used rads

also got a old copper water tank taken the immersion heaters out of it trying to make a heat exchanger to fit in side that at the moment to get some clean hot water out of the system as well

the boiler used to heat a 5 bed detached house so it makes loads of hot water its hard to stop it boiling its self to death and the main cylinder glows red hot got some fire bricks here might try lining it not sure yet ..

next think is a rocket burner for my shed home here got a few ideas how to get blown hot air off that to heat the ferret shed help keep them and the dog warm
