garn burn ?

[Kemer]

Assuming no house load will a 1500 garn go from say 120 degrees to 180 -200 with one batch of good wood or do you have to put multiple loads?

I've got a Garn WHS2000, so I've got about 30% more storage to heat...

I need a solid two loads, at least, to go from 120 to 180. I keep meaning to weigh the wood I load, but always forget. The Garn manual says to load between 50 and 90 Lbs of wood. I suspect I'm in that range, but have no clear idea where exactly. If I remember to weigh it tomorrow, I'll report some more specific numbers; weight of wood used, starting temp, ending temp and overall time of burn. I'll also turn off the heat in the house during that time, so I can get a more accurate answer to your question.

Harold - 30 degrees with no load is easy with one burn. I can get as much as 40 degrees sometimes (depending on the wood). You would need two loads to get a 60 degree temp rise.

The thing to remember is that a couple loads is usually only a 4 hour burn. Several of my local customers say they fire it up with a good sized load of wood and 4 hours on the timer. Then return after around 2 hours to top it off again and let the timer finish its cycle.

Can your heating system provide adequate output with 120* water?

Heaterman,
I have a hot air system(heatpump w/oil hot water backup)I can't say for sure what the minimum temp would be. with my eko the oil would kick in at no fuel
