FREE HEAT!!! Sauna in greenhouse porch heats our house. 

Hello again. Cool! Thanks for your support!!! I appreciate it. I’m honored to have you use it. Take care and good luck!

Thank you for weighing in. I trust you based on your geography alone. Thanks for your support and for subscribing!

As a swede I can confirm

@@ajz2k shut up swede

Thank you for commenting. That’s exactly what I’m going for. So often I see these concept applied only in places that are far outside of the city. Not necessary to be rural only.

Wow. Thank you so much for saying! I appreciate your support!

Thank you for your advice! I noticed after reviewing the film that the lid definitely shifted when I added some water on top of it. It had crossed my mind that perhaps that indicated that the weight of the rocks was making it sag. I know I have seen the lid glowing red hot after prolonged fires so I’m sure it is an malleable state after a long burn. I will keep an extremely close eye on the lid after the next few fires. Thank goodness I have a spare lid ready to go on top if needed. But given your huge amount of experience, I take your advice extremely seriously. Thank you for commenting! As always, I appreciate the foundational work that you and your community have done. Thanks!

@@suburbanbiology having the top get soft enough that rock will shape it is definitely a concern. But I would be worried about spalling happening before that. Plus, if you have to replace the lid and you share that info, then I cannot help but think the whole internet will go psycho about how all rocket mass heaters suck because the tops of the barrels get too hot. I far prefer that your rocket mass heater lasts 60 years without a problem.

I see what you are getting at. I have a basket I can store the rocks in for most burns. Then I can just bring them out for “special occasions”/sauna sessions. I have no interest in prematurely shortening the RMH lifespan or sullying the name of the tech. I toyed with the thought of welding a reinforcement plate into the lid but right now I’m not trying to get that complicated. Thanks again!

@@suburbanbiology Quickie solution: make a rock "donut". Rocks around the edges of the barrel instead of the middle.

@@paulwheaton @suburbanbiology Also, in a Sauna, rocks are used because there's really no other thermal mass to throw water on so that it steams. Here, there's a drum sitting right there. I'm sure just using a windex bottle to mist some water onto the barrel will do the exact same desired effect. It may also even help provide air flow by adding extra cooling to the outside of the barrel. I would just do that very sparingly, and also do it uniformly, so that there aren't residual thermal stresses or distortions on the barrel by, for example, doing it only on one side all the time. But yes, I agree, rocks are probably not a great idea, and also probably not even needed when there's a metal drum right there to use for the same purpose. All that being said, I'm not sure having hot cob in a high humidity environment is a great idea either. I would probably just go for dry heat. A RMH is just such a huge investment in labour, I'd protect it like it's a sacred relic.

Thank you for your comment. I’m very excited about the greenhouse too. Hopefully I can start on it within the next couple months. Thanks for your supporting and for subscribing!

I’m glad you appreciate the details. Thanks for watching and for subscribing!

From a girl in Sweden I have to say you are far more than informed than me. Point taken. The passive solar part of it does function quite well. I took the stones off shortly after shooting the scene that showed them. I was worried that every time I lit the stove it may lead to sagging of the lid. Thanks for commenting and for your support. Happy new year!

I’m honored that you enjoyed it. Thank you for your support and for subscribing!

Me too! I’m very antsy to start building it now!

The plan is to take down the vinyl sheets once the greenhouse has been built. That way the entire wall of the porch is open to the greenhouse and I can leach the excess heat into the house if I open the porch doors. Thanks for commenting!

That’s the plan. Thanks for commenting!!!

Thanks so much! I appreciate you commenting and subscribing!

Thank you for saying so. I appreciate the support!

I’m honored that you found the videos, interesting and helpful. And I hope that they do help you forward with your journey and other projects. Thanks for commenting, and even more for subscribing!

Thank you for your support and for subscribing!

I’m honored to have your support. Thank you for your kind words. Happy new year!!

Glad you enjoyed it. Thanks for your support and for subscribing!

Thank you for watching both videos. I would imagine that you are more informed that some folks that have not seen the sliding door videos. I tried my best to include a lot of detail in the separate video. Thanks for your support and for subscribing!

Thank you for saying!

Thank you. I aim to. And thanks for subscribing!!!

Welcome aboard! I’m honored to have your support. Thanks for commenting!

Thanks for commenting. What really helped build my skill set was learning to weld. If you have the opportunity maybe you could see if they offer than in shop class through your school?? Of course you should ask your parents first. Thanks for your support!

@suburbanbiology ok I'm home schooled but my mom wants to get me lessons on welding and building stuff just like you said and thanks so much for replying to me I didn't think you would 😁

I’m glad you’ve been enjoying watching them. Thank you for commenting and for following along. I appreciate your support!

Thank you for saying so! It’s heating my house as I type this. The amount of solar heat is actually more than I was expecting. Thanks!

Thank you for your kind words!

Right you are. Thanks for commenting and for subscribing!

Thank you!

Thanks! I’m excited to start on the greenhouse too. I appreciate your support!

Thank you for saying so. And thanks for subscribing!

I’m glad you think so. Thanks for subscribing!

Thanks! Will do!

Thank you! I appreciate your comment 🙏🏼

Thank you!!! And thanks for subscribing!

Thanks!

I’m glad you appreciate the work. My friends call me Kit. Thank you for watching, appreciating and commenting. I’m honored to have your support!!!

Man 80 is hot. I think I could get it up there after a few hours, though. Thanks for commenting, and for subscribing!!

I’ll bet one of those little box fans would work great for circulating the warm air through the house.

Thank you for your support and for subscribing!!

You are too kind. Thank you for saying so. I hope that videos like these help empower you and many others to pursue your dreams. Good luck and thanks for your support and for following along! Welcome aboard!

🙏🏼

Thank you for weighing in! I respect your opinion as a Finnish person. Fin? Anyway thank you! I will enjoy it as a relaxation room :)

It says your comment was 25m ago and the video was made 19m ago

The video was initially sent to “members only” for people that have joined my RU-vid channel. Maybe that affected the timestamp? I’m not sure.

Good idea! I’ll keep it in mind. My long term plan is to have a greenhouse on the wall where the vinyl is but if plans stall I may use your tip here. Thanks for your support and for subscribing!

@@suburbanbiology Cheers

Good point. Thanks!

I’ve never heard of an Arizona room. I’ll have to look into that. Thanks for commenting!

I went through the realtors classes here. It was really enlightening. Any room in the house has to have a closet, heating and/or cooling, to be counted as square footage. Thanks for all the great videos and information.@@suburbanbiology

Good points all. Thanks for commenting and for your support!

Good to know. Hopefully it won’t be an issue as I plan to sweep the chimney regularly. Thanks for subscribing and for commenting. I hope this video can help you with your projects!

Lol. Thank you. You are the first commentator to mention as far as I know

Lol

The full video covers a lot of your concerns. Fire bricks on top of the feed tube act as a damper. I pre-burnt the paint off the barrel while outside. World's most efficient stove!!!! Made of DIRT!!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TbdeZKzlV8E.html

🥰

Thanks for commenting! I’m glad you thought it was brilliant. The sheets actually shrink a lot when they’re heated. I demonstrated that in the dedicated video for the sliding doors. Thanks for your support for subscribing!

Thank you for your kind words. I will have to clean the chimney out every season or so. Creosote should be minimal but it’s still a valid concern and chimney Maintenance is important. Thanks for commenting and for subscribing! Glad to have you on board.

Your project sounds like it’s going to be really cool. You should share the details when you’ve done it. I would really like to see what you’re describing. Thanks for commenting!

Thanks for your support and for subscribing! I’m not an engineer. Just a dude who has tried a bunch of things.

Ps I like your user name. I assume it’s Tesla-based?

@@suburbanbiology It's not Tesla-based, I made it when I was around 17. I just liked snails and plaid things lol

Thanks! I search the RU-vid library for stuff that sounds relaxing and just use that. Some folks seem to dislike it but I get more compliments than criticism so far. Thanks for your support and for subscribing!

lol. You’re right. Not OSHA-approved fork lifting.

Probably a very good idea to prevent it from rotting. I used some pressure-treated, but to be honest not all of it is pressure-treated. Hopefully the paint will help resist.

I have already used the passive solar to get the porch up to above 100°F when the ambient temperature is only about 50. It’s pretty impressive what the solar part does let alone what the wood heater does. Thanks for commenting and for subscribing!

Makes sense. I guess I could construct a tent or false ceiling around the barrel. I probably won’t though. Thanks for commenting!!

A shop vacuum into the feed tube gets the ashes out in about one or two minutes. It’s not really that bad. Many people have asked the same question though. I’ll have to show footage of it in a follow-up video. Thanks for your support.

I appreciate the comment. Thanks for weighing in!

Shop vac into the feed tube gets them out easily. Thanks for commenting!

If you stick a shop vacuum into the feed tube, it’s quite effective at getting the ashes out very quickly. Thanks for commenting.

Good news! I dedicated an entire hour + long video on how to build the heater. See below. Thanks for commenting and subscribing! And the ashes are cleaned out, using a shop vac into the feed tube. World's most efficient stove!!!! Made of DIRT!!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TbdeZKzlV8E.html

It traps heat extremely well. The vinyl sheets trap solar heat also. The moisture part is a little less dramatic. Thanks for commenting.

Not yet. The porch is currently serving as the tiny greenhouse. Big one coming soon. Welding table and fence are next. Then big greenhouse.

Thanks for the tip!

The sliding door is a single unit. There is a sill that’s attached to the side walls of the frame. The sill contains its own track. They even make replacement tracks if that part wears out. Thank goodness mine was in good working order. Thanks for your support and for subscribing!

Thanks for chiming in. The heater was the most expensive thing to build. The vinyl sheets weren’t exactly cheap but I bought a bunch extra. Thanks for commenting and for subscribing!

I hadn’t thought of the Finns. 😂 you’re probably right. Thanks for commenting!

Good to know. I have only really used it for dry heat ever since I shot the video. I will probably just do that instead of adding steam. Thanks!

Thank you for commenting. I’m glad that you enjoy my projects. Yeah the pallet lift was a little bit dicey, but it actually wound up being safer than standing on a ladder probably. I looked up, practical self reliance, but I can’t seem to find their channel. Thanks for your support and for subscribing!

@@suburbanbiology My apologies, its not a channel but a website. I should have specified. I'd have included a link but sometimes RU-vid doesn't like that.

Is there a bad way to sound like Matt Damon? I guess maybe interstellar 🤔 either way thanks!

In truth I haven’t used much steam since shooting the video. Mostly dry heat this winter. Thanks for commenting!

@@suburbanbiology How cozy has it been?! 🔥🤗

I suppose it could work as long as you buried the tubes in enough thermal mass. If you just laid metal tubes under your crawlspace, though, I think that sounds like a pretty significant fire hazard. So this is more in the theoretical realm. But theoretically it could work. But please don’t do it ;)

@@suburbanbiology but it is only smoke and warm air that is passing through the pipes right? Can the pipes catch fire? Or do they become extremely hot?

It worked extremely well. We have mild winters but the vinyl sheets got the porch up to 100 some days when it was on the 50s. The RMH did its job too on the coldest day or two. I probably lit it up about ten times. Thanks for commenting and for subscribing!

@@suburbanbiology you're welcome. I wsa genuinely curious. I mean this winter was nothing like the bad one a few years back where we lost the grid. that one was baaad for us. lol I lost power. got it back 3.5days later and had the pipes freeze the same day. so then I had power but no water. I had to lol about it really

I try not to mix those two up. Where did I misspeak? At the foundation scene? Thanks!

Shop vac into the feed tube. Thanks for commenting!
