Anyone have any experiance with building...

A outside wood burning furnace, I have to find a way to get my electric bill down this upcoming year and thought about adding a forced air wood burner outside, not the boiler type Anyone know how they operate and what keeps the smoke from entering your house, I have plenty of 1/4" and 1/2" plate I can use to make the firebox with, just need ideas on how they workJon

Reply:I remember reading once, many years ago, of creating a small building like from the Heat Source web site.  About the size of a double depth outhouse, but made of concrete blocks, with a web of sealed air ducts (found from your neighborhood Home Depot) wound about above a firebox.  Then this was filled in with sand around the firebox.  Connect your air ducts & it will circulate warm air through the forced air system in your house.Problem with it,  it would take forever to warm up, but you would only need to stoke it once a day with wood.MarkI haven't always been a nurse........Craftsman 12"x36" LatheEnco G-30B MillHobart Handler 175Lincoln WeldandPower 225 AC/DC G-7 CV/CCAdd a Foot Pedal to a Harbor Freight Chicago Electric 165A DC TIG PapaLion's Gate Build

Reply:This guy has been to lots of places in the US. And he knows some of them get pretty cold.I think most of these slower passive solutions are good if people don't have huge expectations. The aim of them is to provide a base level of warmth that can be topped up when needed by other heaters. Heating a cold building is hard and expensive. Heating a prewarmed building is quicker and cheaper. So think of these things as 'prewarming' a building.Last edited by scott brunsdon; 09-07-2009 at 08:26 PM.Yeah, I carry.House keys, wallet, some change, usually a newspaper, maybe a pen.
Reply:Build your heat exchanger about like the old stokers and stokermatics were, a box of pipes inside a fire box. Seperators in the middle if needed then your end plates serve as as the seal from the fire box as well as the attachment for your plenum. A duct in from the house on one end and a duct back to the house on the other = recirculate the air. A fan of course.
Reply:And for you desert dwellers, there are easy passive cooling solutions you can make. You need a big loop of pipe buried under the ground. One end of the pipe enters the house, the other end exits the house. An in-line fan pushes the air through the pipe and it gets cooled under the ground. Easy - except for the digging bit.Yeah, I carry.House keys, wallet, some change, usually a newspaper, maybe a pen.
Reply:The digging isn't so bad here in Yuma.  About 300' of sand to dig through before you get to bedrock, but you run into water first.Those passive cooling/heating systems are used in the Midwest on newer homes if there is enough land around.  Easier to heat/cool 50*-60* water/air than it is to heat/cool ice cold/extremely hot air/water.MarkI haven't always been a nurse........Craftsman 12"x36" LatheEnco G-30B MillHobart Handler 175Lincoln WeldandPower 225 AC/DC G-7 CV/CCAdd a Foot Pedal to a Harbor Freight Chicago Electric 165A DC TIG PapaLion's Gate Build
Reply:I reckon you'd only have to go down a metre or so.Yeah, I carry.House keys, wallet, some change, usually a newspaper, maybe a pen.
Reply:To get to the cooler air, you would have to go down about 6' or 2 meters (there about).  That sand holds a lot of heat in it.Most in the midwest go about 42" or more to get below the frost line & a more stable thermal area.MarkI haven't always been a nurse........Craftsman 12"x36" LatheEnco G-30B MillHobart Handler 175Lincoln WeldandPower 225 AC/DC G-7 CV/CCAdd a Foot Pedal to a Harbor Freight Chicago Electric 165A DC TIG PapaLion's Gate Build
Reply:I don't have experience building one, but I do own an outside woodburning furnace.  There is a water jacket around the furnace that has a thermostat connected to a blower, and when the water temp gets under 170 (adjustable) the blower kicks in and gets the fire going.  Then, when I need to heat my house, a water pump pumps water to a coil that I added to my downdraft system and the air blows across the heated coils and through the house.  My electric house heater still works, and I keep it at 68 all winter long, while the Hardy (Brand name) thermostat stays at 72.  There are some firebox dynamics with this system that cause this backup to be really convenient... going out in the 20 degree weather at 4am to kindle the fire really stinksNow, inside the water jacket, is another coil where the water supply for the water heater goes from the house to the Hardy and back to the house and into the water heater, thus, at the very least, pre-heating the water, but also, after several showers, the Hardy is supplying close to 170 degree water to the house directly, when the electric water heater can't catch up.I'd be glad to take some pics for you if you'd like, and I have the owners manual too, if you are interested.Hobart 125Words mean things
Reply:I'd be interested in seeing a few pics of the system. I've had something like that in mind. I have no real feasible way of putting a chimney into my house, without sacrificing a good bit of needed space. Out in the yard seems like a good alternative.I've been debating whether air or water would be the best heat transfer medium. Supplementing the hot water heater is a bouns! With a house full of teenagers it seems as though the shower never shuts off, as I tearfully watch my hard earned shoe selling money going down the drain.Damn you Kelly, damn you Bud, and DAMN you Peg!!!!@*&^%&#Last edited by Al Bundy; 09-11-2009 at 10:37 PM.
Reply:I'm actually having to do some maintenance on the furnace.... it's been leaking for some time, and I took of the outside cover and opened up the top (where the seal has just given up the ghost).  The actual water "jacket" is a tub/compartment with about 20 gal. on top of the firebox, and the water in that tub is used to go through the house and heat the house.  Inside of that goes a copper pipe with a loop or two in it that goes to the hot water heater (we haven't disconnected the hot water heater).  It's really a lot more simple than I thought it would be, and when I get to cleaning it up and fixing the seal (once we get a sunny day here), I'll try to remember to take pictures.Hobart 125Words mean things

Reply:I don't, but I hope to someday.  I have a old fireplace in my basement that works fine, but I saw some place online an idea of taking an old electric water heater and turning it into a fireplace.  It's pretty close to setup right for that, all you need to do is make some large holes, add a few hinges and you are set.  I'd like to make one with a nice big see through door.  I love watching a good warm fire.Miller 330 a/bp water cooledI believe in gun control, I hold my gun with two hands.  If you want to know why, click here.Buy American or bye America.
Reply:Im about to build a water jacket heater out of a half of a 1000 gallong tank.   I heat with hwood but my problem is the bead room my wife and I use is 2 feet lower than the rest of the house.  Its hard to heat. I hd central heat but its too expensive.    Last winter my wife got tired of being cold so I took a 30 gallon oil drum and welded a door on it and then put a stack on it.    then I cut a circle in the  top of a 55 gallon drum and then split it lenght wise to put the 30 gallon inside it and cut   a pass through hole for the stack in the top of it.     I then opened the bedroom window and mouned a plywood cutout like  a window ac unit.  I had a small portable ventilation blower out side to push cold outside air into the space between the heater and jacket.     Then I put a hole in the top of the heat jacket at the back and ran dryer vent hoses from the back of the heater to the window.  This worked very little.  I got to thinking that it was like blowing in a coke bottle.  The air thats in there cant compress much or move.       I then plugged off my blower hole and then put the blower in the house on the floor.   Then I put a ven hose up and through the windw mount and down to the base of the heater.   This way it provided a negative pressure inside the house and let the air circulate alot better.   the fire wouldnt last all night so I took some 3 inch crushed  base stone from woork and put it in the heater jacket part way around the jacket.     It works great staying hot all night long.  I wil try to get a few pics of it when I i start  getting the place ready for winter.
