OK, I'm an advocate for the RMH and masonry heater concepts. So along these lines, I have some questions for those of you experienced in operating your RMH's. I don't have one, nor have I operated one. I've operated just about every other wood burning apparatus, but not a RMH, and least not one built as such. I got a rockety flue fire going once, but that was a different concept.

My assumption is these are by and large no different than most free standing wood stoves in that they are space heaters*.....as opposed to a central heat system. So how large of an area does your RMH heat? As in what size burn chamber, what is the cubic feet of the mass and square footage the area being heated? If not a single room, how do you distribute the heat to the surrounding areas? * Highly efficient space heaters, but still they only heat a defined confined space.

What is the ambient temp in the room. I understand the difference between the comfort level of radiant heat vs. ambient heat, but want to know the ambient heat anyway. It helps to explain to others how it works and also how it affects relative humidity inside the structure.

When these things are running, what is your outside air temp in relation to inside air temp? In other words, what is the inside / outside temp differential? The Delta T?

How well insulated is your structure........from none to what R level? If insulated, what is the schedule? Vapor barrier? Insulation type and amount?

What is your floor structure? Wood, cement, dirt? Floor covering?

Will probably thinks of more things to ask, but that will do it for now.

Have a look at my thread..... alot of these question are answered there.  Including charts on burn times, indoor temps, out door temps and insulation values and sizes . . .


I would just love to have one of these things in my house.... It may not heat every single room nice and toasty warm, but for me I look at the chance too SUPPLEMENT heat . .  and reduce the bills . .  the very fact that you can burn less wood, while having hours of latent heat is just great !
