But you do have to run them at a level that keeps the stove and flue in an optimal temperature range for good performance, no?

For a 26kW stove this is going to involve more effort (and produce more heat) than a 3kW stove.

Very interested to read about how much legwork is involved with keeping it at the minimal good burning temperature.
That's an interesting concept. If we say that a good operating temperature is 200C, then a big stove at 200C is producing more heat than a small stove at 200C... yet both are the same temperature....

idea

I suppose it's because the surface area is bigger smile
But the small stove will be burning the fuel much more efficiently and won't be loading the chimney/liner up with deposits which will later catch fire and burn the entire house down hehe

Sounds like someone doesn't know the difference between heat and temperature!

Its not.
Its like saying:

it will work, but its not the easiest or most efficient method of getting bread.....

My example is better than yours, and it's based on experience not theory.

Well, I've got a 16Kw woodburner and I manage to run it at low heat levels whenever I want to. Only tried it full blast once, not repeating that experiment.

All the wood is converted to ash (burnt efficiently) and no clogging of the chimney.

This was handy when I bought our stove:

Had to get it on the pickup with an engine hoist and a lot of swearing.

The telehandler was handy for putting it into the house too:



That's a 9kW stove with back boiler - 4kW to room, 5kW to water - and at full chat, we have to wear t-shirts and open the windows.

Update

Ready for new stove:



Old clunker gone:



New one in:





Got flue issues (man flue?) so not finished yet, installers need to build an elbow joint to circumvent a ceiling joist, should be finished Friday.

So, how well does it run at lower outputs?

26kw is OTT, however................

I was advised to install a 4kw by a salesman who worked it out by room size and a booklet, so I ignored him!! and bought an 8kw from a local farm store.

When an independent installer arrive to fit it, he said I did the right thing, and I'm glad I went for an 8kw, don't forget, you can have it as hot as you like depending on how much you throw in it, mine heats the whole house providing I open all the doors. Best thing I put in the house, still restoring the house.

Aha yes I wondered how you were going to fit it into the old hole...

Actually it doesn't look as big as I thought it would. Are you sure it's not a Sony 25" Trinitron CRT TV?

Made me chuckle.

I'm about 15 metres away from it when I took the pic.

It is big, the firebox internals are 730mm corner to corner.

I'm not sure what you mean by good performance? The newer burners have slightly less ash because they more efficient but the OP isn't buying much more than a fire box.

Our homemade woodburner will happily run with one log or glow red with three dustbin fulls of woodchips.

Interestingly, following the OP's link, his stove only requires a 150mm flue, the same as a burner a third of the size, so he should get a decent draw with smaller burns. He'd have to go out of his way to fur up the flue.

OK. The door tars up very quickly and you find yourself cycling between burning well, going out and recovering if you don't have enough fuel in there. Certainly having a single log in there needs a lot more attendance and fiddling than just letting it do its stuff. It has an automatic thermostat which helps, but certainly runs better at 60+% full power than 30%.

I'm pretty happy with how well sized it is for the room and house - we probably went through two tonnes of wood this winter and really enjoyed having a warm, comfortable home.
