By placing the fire and chimney on opposite sides of the house and constructing a tunnel between them, heat is pulled through the tunnel, heating the floors and helping distribute heat more evenly.

Note: caused a significant number of house fires and carbon monoxide poisoning.

You mean putting an open flame under a house could be a safety concern?

[–] [email protected] 15 points 10 months ago (2 children)

I figured there were some issues like that, I think I'm more into the general idea than this specific execution

[–] [email protected] 12 points 10 months ago (1 children)

Radiant heat using pumped hot fluid (I think usually a water antifreeze mix in a closed system) in tubes attached to the underside of the floor, seems like the closest, safer mix. Could be reasonably solarpunk if the source of heat is good

Did you just invent UFH? 😂

No, just recommending it since it sounds like what they're looking for. Some of my relatives have a house with it

[–] [email protected] 5 points 10 months ago

Heat pumps are significantly more efficient than fire. Using a heat pump with a high r-value house will keep you toasty without the issues.

Piping it through the floor means you'd have the same radiant heat.

Yeah, it might be better to have it be a boiler system instead, with water piped around the house. Or since the house will have the heating in mind during construction, then make the heat source centralized with proper insulating house walls.

A very similar system was used by the Romans. They called it hypocaust.

I'd like to learn more about the Goodlejang, Guemdol, Gaejari, Bunumgi, Jae-Agungi, Butu-mak, and Ondol Floor please.

No, a rocket stove is a heating chamber with insulation around it to direct the heat to the top and heat up a pot or something similar. This is a heating system for a house.

[–] [email protected] 5 points 10 months ago

Put a pot over the chimney.

Rocket house stove.

[–] [email protected] 1 points 10 months ago

The pot in this system is the butu-mak. While there might not be an internal chimney like a rocket stove, this kinda looks like a rocketless rocket mass heater.

So having an open flame roaring below your floor boards is fine, but leaving a fan on in a closed room isn't?

[–] [email protected] 11 points 10 months ago

How did they get the house to float though?

[–] [email protected] 7 points 10 months ago

I like the Hangul and then "Chimney" and "Wind Protectioner".

as far as i'm aware (not korean, never been there, just an internet weirdo) ondol heating of a sort is still used for the floors in korea. i assume it's more of a radiator system now though?

[–] [email protected] 4 points 10 months ago* (last edited 10 months ago)

Yes. (Linked article is Korean)

Modern ondol systems use piped hot water. One of the pleasures of being in Korea in winter is finding a literal hot spot to sit or lie on, since the heating is not perfectly even.

A traditional method for asphyxiation via carbon monoxide.

[–] [email protected] 4 points 10 months ago

We have modern variations like this which are less dangerous and could be modified to work well within the solarpunk paradigm. Induction heating where the water is ran through pipes under the floor for example, there are some who have used solar water heaters on the roofs of the home to heat the water for this process, without needing to use an extensive amount of gas.

How is airflow achieved? In a traditional fireplace (or rocket stove) hot air rises up a hot chimney to draw smoke up or create pressure to push smoke through some ducts. How is that happening here?

[–] [email protected] 1 points 10 months ago

It's not totally clear from the diagram, but I think the fire pit itself is outside the house. The air naturally ducts underneath the floor of the house and then up the chimney in the back. There's still a chimney effect, but it gets redirected under the floor first.

You mean... fire?
