How long should a ton of timber last

kah22

Doing some Googling tonight I came across a product called 'Hotties,' a product made from compressed wood chips, sawdust, and it would seem suitable for a glass fronted wood burner. There also appear to be other such logs but 'Hotties' seem the most popular. From what I've managed to read it would seem that while the upfront price is more expensive because of their consistency they may prove more economical if buying a yearly supply

Then I thought Bord na Móna and wondered if they did any products like a manufactured log suitable for wood burning stoves.

Now I must admit I was thinking turf when I discovered they do a product called Eco Logs which seems to be the same sort of thing as Hotties - sawdust, compressed wood of some kind.

Anyone on the Forum know anything about them - effectiveness, how long they burn, heat put out, that sort of thing. Price, well I suppose that will be different in various part of the country, I live in the north.

Would love to hear the views of anyone who has tried them

Chime y cleaned yesterday. Testing seasoned logs today

For us Eco Logs burn far too hot. Fine if you only burn say a max of two at a time but you'd get six in our fire but that would start a melt down.

Definitely good heat also burns quicker than decent dry hardwood.

Price? Worth buying in bulk?

When I buy the stove will probably be 5kw

Dathi, the energy content of firewood depends on it's moisture content. At the same moisture content, softwood has a higher energy content than hardwood.
You are however correct in saying that in general, 1kg of coal = 2kg of dry firewood.

yes it was late when i posted and i just pulled the figures of the seai website without explaining them

Honestly no idea what price they are in bulk but they are convenient. I would however like to see them burning in one of those steel morso stoves before I used them because they do get very very hot almost comparable to coal. If you were to start a fire walk away and then forget to turn it down with a few eco logs on it I'd want to know it wouldn't do any damage before buying a lot of them.

ill give you my take on it..I have a stanley erin multi fuel stove and was palnning on running her on coal and wood blocks, im in Donegal btw..I bought a tractor trailer of logs for 150 euro and was planning on starting the stove with coal then running her on wood for the rest of the eveining, I used up the logs in 60 days and figure that they were so overpriced I was better putting the 150 into coal, never mind the carrying and the stacking etc...logs are so way overpriced its a racket..

I know this is an old post, but....
That works out about €2.50 A day.
The same as I use in a multi fuel stove, which is burning approximately 20 hours a day in the winter.

€.75 per litre
X 4 litres per hour
X 20 hours
You're talking €60 oil per day....
Even half the hours of oil is €30 per day....

Personally, I find hardwood logs the way to go...

Ridiculous assumptions.

4liters x 20 hours x 10kWh(heat energy content per liter) x 0.8(efficiency)= 640kWh of heat energy

Do you realize that it would be unbearable to live in that house with that amount of heat pumped in during 20h period? That amount of energy would be enough for 1 week at least. Also the heat would impossible to distribute around the house without back boiler.

IMO logs are only viable if you get them for free or very close to it.

I don't use oil at all. We've an 18kw boiler stove which we burn logs 90% of the time. Very rarely would we use coal.
The point I was trying to make is that €2.50 A day or €17.50 a week for logs to have a fire burning approximately 20hrs a day in winter , is cheap IMO....

Can you tell us how much those €2.50 logs weigh and more or less how dry they are? Hardwood or softwood?

Only buy hardwood , the last few loads was birch. Generally cut down the year previous. Not kiln dried.
Once the fire gets going , we close down the vents. Not sure of the exact weight of the logs, trailer load would be about 2.5 to 3 ton skip / builder bags or there abouts

How long would it take for you to go through this amount of wood?

similar to the person in the post I originally replied to....
€150 worth would last 60 to 70 days of the fire going 20hrs a day in the winter...

I find insert stove gets through timber very fast if only using timber so a "ton" wouldn't last that long.

restrict the airflow your using your stove wrong

an open fire should use more fuel than a stove
