I prefer something that warms up the room fast and burns for hours.
Those things look they they smoke up the house a lot and appear to burn the wood quickly and give off heat slowly for hours.
Condensation and creosote look like it could be a problem.

The whole point of rocket mass stoves, is to burn very hot, for maximum efficiency - and almost no smoke, and no creosote. They take a fraction of the wood (1/5th to 1/10th!) and they have a higher average temperature in the building.

I have already calculated this out.
When it's freezing out side I burn on average 4 to 5 pounds of wood per hour.
That's about 40,000 btu per hour of fuel.
If I replace that wood stove with a 100% efficient propane camping heater I run the camping heater on high at 18,000 btu per hour it doesn't get nearly as warm.
So if I start burning 1/5 the wood even at 100% efficiency that's about 8,000btu per hour. If I turn the propane heater down to low which is about 8,000 to 9,000 btu per hour it doesn't provide nearly enough heat to keep the living room and surrounding areas warm.
A rocket mass heater could probably reduce wood consumption by up to 1/3.

I am using a lot less wood now with a wood stove compared to a fire place. The wood stove provides more heat and uses 1/5 to 1/3 the wood and the heat spread out much further into the house.

My parents burn wood for heat. Many, many days spent cutting, splitting, hauling, stacking..... no way in hell will I go back to that. We avoided pine wood like the plague except one winter that's all we had for a couple weeks.

Had a chimney fire and dad swore if off forever. He was in such a hurry to put it out, he threw the boxes of baking soda down the chimney without even opening them!

I have been burning a lot of pine in the coal furnace. The build up thus far is very light soot, but I burn the coal furnace hot.
Things tend to come full circle.
Plus wood is the most prolific home renewable energy source.

When you burn more / most of the volatile compounds, you get more heat out of a given amount of wood.

A good rocket mass stove has a flue temp of about 150F, as I understand it. It is largely carbon dioxide and water vapor.

Yeah it burns hot and fast like a wood pellet burner.

I found a 1,500VA UPS that runs off 48v.
Looks like where I work they have a few of these and they replace it new every year.
So.... Another one next year?

Next will be water. I have a 45ish cm well on my property.
Only problem is its over 100 meters from the house.
If I had my way I would build the house around the well like a midevil keep.
Do your local zoning laws allow for a granny flat?

Not one per year a dozen or so.

Zoning laws are almost nonexistent for residential.

Cool. Put six or eight backhoe arms on a 20ft shipping container and run it off a Tesla battery pack.
