Is the mf3000 capable of heating two buildings?

[willieG]

2 crap houses

I think what Mr. WillieG is trying to say is it can heat two very well insulated 1500 Sft houses.

The mf 3000 only has one set or ports meaning one supply and return, if it was doing 2 buildings it would have to be a small loop to a small building off of your main loop

Almost always when someone wants 2 structures we guide them towards mf 5000

Thank you scott7m that's the info I was looking for

I think what Mr. WillieG is trying to say is it can heat two very well insulated 1500 Sft houses.

i think that might be the max

it is rated at 'approximately 170,000 btu per hour"
 2 small houses (or) 3000 square feet on a very cold night in a well insulated house may run as high as 40 btu per square foot...3000 x 40 = 120,000 btu per hour....22 pounds of dry wood at 80% efficiency per hour...264 pounds of wood for a 12 hour burn... also to keep that "magic delta of 20" you would need to deliver 12 gpm (of course if this was 2 small houses you would only require 6 gpm to each house)

THIS is worst case scenereo. This is how someone sizing your furnace would do it...they would do a heat loss on your house and estimate the codlest temps you would ever see in your area and size the furnace to heat your home in that weather. normally you would use far less per per hour

i would say this model would be designed for more like a house (well insulated) of about 1800 to 2000 square feet ...on that coldest night of winter you would get by on about 180 pounds of wood for that 12 hour burn and only require 8 gpm (easily delivered by 1 inch logstor and easily deliverable with a small circulator)

I agree Mr. WillieG. I like the 50% rule! Mark your square footage and get the stove rated for twice that. Obviously your BTU calculations will be more precise, but, more often than not I think the 50% rule works.

But, I think Scott answered the question Mr. brokenaxe meant to ask.

It totally depends on the size.
