rocked heater fuel needs, area it can heat?

Hi newbie question about the rocket heater, as i intend to build one before the cold starts, which is only a month or so from now down here in the southern hemisphere , i already tore down the standard one we had so no other choice!

In some of the youtube videos , i see that they need only little amount of wood per day, and it can go on without refueling for hours, but elsewhere i read that you have to feed it every hour and a half or so.

i want to figure out if a rocket heater with a 200 litre barrel would be ok to heat this place, it is about 45 sq meters in ground floor, then 2 rooms upstairs but those could be heated independently.
Would a rocket heater be enough or is it meant for smaller rooms?



Thanks

I have been scouring the forum for a similar answer. My place will be less than 1000 sqft with the sleep loft. I havent learned the difference in the pipe size, or if there is just one standard barrel size. Just a fellow newbie.

In the Wisner's 8" Cabin RMH plans they said: "Heated 840 SF cabin (R­30­-36 insulation) in Okanogan Highlands (elev. 3800 ft). Used 1 cord of local firewood per year: 30­-35 lbs wood (4 hr burn) per winter day in sub­-freezing weather; or every 2 spring/fall days."

Sounds like they run it for four hours a day and let the mass do the rest.

Wow! Yep...it should heat my place well then as we live in central oklahoma. I do believe I need to order the book I keep reading about...and start experimenting. thank you
