Rocket mass heater owners - willing to give tour and ask questions about their heater?

Hello! I have been reading about rmh for a while and am wanting to build one. Before I made the huge remodel commitment though, it seemed like a good idea to at least talk to someone about how it worked (as in, what sort of heat it put out, how well it heated their entire house, etc. - not how to build it or use it). And maybe even visit a home with it while it was being used to see what the result was? I live in Texas, north of Houston. Is anyone in this area using them? or anyone willing to endure some question/answer drills?

Hi L;
Ask away.
I have four RMHs here, including my newest one, a Shorty core built indoors rather than in an outbuilding.
My wife resisted this build for three years, and she resisted it while I was building it.
Now, she is Shorty's biggest fan.

I'm in Montana so that a visit could be cost-prohibitive for you.
If you would prefer, you can write me directly at dragontech@blackfoot.net

Montana! You certainly experience more cold than I do!

First question - All of the discussions I have seen emphasize the fabulous heat of the mass that is usually used as a bench, etc. And a heated seat certainly sounds wonderful! But, my interest is in how well it heats the air of the rest of the house. If I am not sitting on the bench, how warm is the rest of the room? And if the heater is in the living area, what chance is there of the heat making it into the bedrooms?

Depending on the interior design of your home, a mass heater will create a toasty, warm zone all around it.
Fans can be used for back rooms.
Heat registers can also help keep your whole house warm.
Imagine having 500 bricks radiating 150F all night long, sitting in your living room; everything warms up!

In northern Montana, temperatures were below zero at night and in the low teens during the day all last week.
In our 97-year-old house, we burned one small fire in the morning and the same in the evening.
The temperatures were even throughout the entire rambling structure, and there was no fire all night or all day!

With a traditional steel box stove, it is hot near the stove, warm five feet away, and chilly the farther away you get.
In colder climates, a steel box stove is lit 24-7 all winter.
Your chimney can become plugged with creosote, and chimney fires are always a possibility.

Our new Mass Heater is like having central heating in a 100-year-old home!

Most new RMH builds do not use a long low bench, rather they use a Stratification chamber (brick bell)
It is much more comfortable to sit on a couch or a recliner than on a cob bench.

My bell-style RMH is at one side of the 25' x 26' main floor, and the entire floor is comfortable when it has been running, even the stone-floored entry hall at the opposite corner. Radiation from the mass makes all surfaces in sight warm, yet the heater surfaces are only pleasantly warm, not uncomfortably hot. The lofts are always the warmest places aside from right next to the heater.

I would love to visit someone with a RMH as well. Is there anyone near Indiana or Michigan who could give me a tour?
