I'd like to build a small RMH for a 10'x12' shed, and would like to use a smaller 30gal steel drum. Trouble is, I don't know where to find one (30gal steel drum). I'd rather not cut up an old propane bottle (or the like), as I would like to also use it to heat up water on top of it, etc.
Any advice on where to find a nice 30gal steel drum would be most appreciated.
Automotive quick lube shops generally offer them for sale. If you are in an Ag. area then a farm maintenance shop should have empty's.County road crew shop could have some. Check craigs list in your area. Somebody has one you just need to find them.
Hey everyone - well, I found one! I pass by a schoolbus maintenance yard not too far from my base location and thought I'd check with them. The guys were friendly and helpful, and they did have a used 30 gal steel drum they were willing to give me for free(!) I was on my motorcycle at the time, so I came back the next day to pick it up, and I brought 'em a six-pack of beer as "thanks." So, I now have a 30 gal steel drum I can use to make a rocket mass heater for my small shed. I'm jazzed.
Now, I just need to buy some refractory bricks, fireplace cement and 6" stove pipe and get building. Yeeehawww!
Hey Donald: Congrats on locating a barrel ! That's the permies way ! Hopefully you explained RMH's to them and one of them will want to build a RMH as well ! Couple of tips for you. Stove pipe) you only need the expensive black pipe where the highest heat is or a high abrasion area , any other place you can use hvac thin wall pipe... MUCH cheaper ! Readily available in 5' lengths. Refractory cement) You don't need it... A very thin layer of Fire clay and sand mix is how you (cement) your fire bricks together. Locate a masonry supply house , they will sell full fire bricks and 1/2 thickness fire bricks and maybe even insulated fire bricks ! They will also stock fire clay in 50# bags. Do not try to find fire bricks at the big box store ... IF they sell them they will be outrageously expensive being called wood stove replacement bricks . A brand new heavy dense fire brick should cost 2-4 $ no more. Fire clay should be $ 10-15 a 50# bag. Regular clay for general cobbing is found near creeks or on a forest road , or talk to a contractor who is digging foundations . County road crew could tell you where there is a clay pocket near a road. Oh YEA , BUY the RMH builder guide ... available at amazon and many other places. it will keep you from making common mistakes . Sand is the other thing you will need .. more of it than clay ... No ocean sand but any creek sand will work fine.
