![]() With winter immanent, I'm looking at putting some heating in my shop so I can work and not freeze. I've heard people say that any kind of open flame heating is dangerous because it could ignite saw dust--I've heard others say this is rubbish. Could people share their opinions and advice? Is an open flame heater dangerous? What type of heating do you use? Any recommendations to heat my shop: it's about 20x20 with a 12 foot ceiling. Thanks, Dave. |

I use a small karosene heater and keep it on a bench near the overhead door,
also prop up a small fan behind it to circulate the air and a coffee can of water on top of it. I'm in a 12X18 uninsulated shop and haven't had any problems with it. I also have a electric heater that's mounted to the ceiling over the bench. I use it when I first go in the shop till the karosene heater warms the shop up and also put it on low if I have some finish drying. Mike S.

I have been heating a three car garage/shop with a 24K BTU kerosene heater
for years but it demands attention and discipline. 1) Heater is always kept away from work (ie. Heater is usually in bay 1 while work is done in bay 3, some assembly in 2. 2) Heater is cleaned regularly and kept clean. 3) Fuel and flammable materials are kept completely away from heater 4) Any time finishing is done with flammable substances, the heater is turned off. 5) I keep the shop cleaner during the winter (sawdust, etc) when using the heater. I do supplement the kero heater with a small quartz heater that puts out a surprising amout of heat. I have a permanent shop building in the plans and I hope to heat it with a recycled forced air furnace. I have done this before in a shop and it works well and is fairly economical. My previous installation was raised off of the shop floor about 1-1/2 feet which put the firebox about 3-4 feet off of the floor. These used units are available through salvage building material dealers or heating contractors. I paid $25 for my down-draft unit and just let it blow out on the floor of my small shop. My cousin did a similar thing with an updraft unit that he uses to heat a 1,200 sq ft shop. He put a simple two-directional plenum on top and it does great - think he paid about $100 for his. He used a similar lift to get the machine up off of his floor. "Dave Rathnow" wrote in message news:OZ3Xc.55635$X12.38428@edtnps84...

Is an open flame heater dangerous? What type of heating do you use? Any recommendations to heat my shop: it's about 20x20 with a 12 foot ceiling. Open flame can be worked with...I've got a good friend who has been heating his shop with wood for over a decade. It requires specific care with finishing in the winter, but otherwise is fine. I know a local pro who heats with wood, too, but the stove is isolated, in the basement, and not a problem with fumes and dust. I've used propane catalytic heaters for mine. They work well, but are expensive as all get out...tendency to burn a full 20# tank of propane per day in cold weather is not good. The cost of the stuff is way up...last time I used it, I paid $9 and that was 3 or 4 years ago. Currently, I've got an electric furnace almost hooked up. IF you have the wire capacity, it's a good way to go. Mine's in the shop "attic." I'm lazing my way into hooking up the 60 amp breaker one day soon...when it drops under 80, probably. Cost? Zip. Got it when it was removed from a house for a new type of furnace. Check with local HVAC people. Other sources: mobile home supply houses. They often have small, surplus electric furnaces. While I use kerosene to clean some tools, I do not like the stench, and have been through the kero heating mill. No more. Stinks. Requires care both because of the open flame and the fact that output heat losses are high if you don't keep the heater extra clean.

I salvaged a woodburning fireplace insert from a job that was never used.
It came complete with flue, flashing and cap. I've used it several winters to heat the shop (24'x22' insulated) without problems. I am just careful to clean the sawdust off the floor often. Takes about 1 hour to get a good fire rolling and get it warm in there. I just love going out into the shop on a snowy morning and building a fire-- who'd thought a woodshop could be "cozy". On especially cold days i also use a kero heater. These type of heaters will give off soot and odors when the wick needs replaced, otherwise they work well. If you decide on a wood burner i would strongly suggest getting a fan kit with it. Furthermore, if you need to buy wood, call BEFORE it gets cold, prices are usually better. I go through about 2 cords per season in the shop which amounts to about $150 split and delivered. (the guy gives me a little deal 'cuz i refer his services to my own customers). Keep in mind, you should also have plenty of endcuts to use for indling. --dave "Dave Rathnow" wrote in message news:OZ3Xc.55635$X12.38428@edtnps84...

I have had two shops and have heated both with small direct vent gas
furnaces. There is no open flame so there's no risk of an explosion. The furnace draws and exhausts air directly to and from the outside and the air is heated in an enclosed chamber. They're hassle-free and you have the benefit of a thermostat. I turn it down to 50 when I'm not using it and up to 65 when I'm in the shop so the shop is heated to some degree all winter which I like. Only takes about 15 minutes to bring it up to working temp. My current shop is 22 x 26 and well insulated and doesn't take much to heat. Cost for the furnace was about $700 and they are easy to install yourself. You just need a gas line to tap into and an outside wall. "Dave Rathnow" wrote in message news:OZ3Xc.55635$X12.38428@edtnps84...

Dave,
An open flame heater is not dangerous as long as you respect the fact that whatever you are doing in the garage may have the potential to put that garage into orbit ;-) Basically what I am saying is just use your head when you have an open flame. You can rip, cut, saw and plane all you like as long as you keep the sawdust piles cleaned up and not near your heater. I have never heard of sawdust in the air exploding like gasoline fumes. Don't have a messy shop with piles of sawdust all over the place. Get youself a couple of STEEL garbage can's and when you clean up your sawdust keep it outside in those can's. The reason for the steel can's is that if you ever happen to get smouldering embers in the sawdust, it won't melt the can if it does start on fire. And make sure you keep it outside, if anything does go wrong and you have a fire, it's not inside your garage. Same goes for shop rags etc. that you may use for refinishing. Put them in a steel container when finished with them and don't keep em inside your shop. Spontaneous combustion is well known to happen to solvent soaked rags, you don't even need an open flame for them to go up ! Now as for what I heat my shop with.... well I have used 4 different types of heat. In my old shop I used one of those propane construction heaters, and like Charlie says, they are hard on propane.... until I discovered one thing. Put a fan behind the heater. It was amazing how low I could turn the flame on the heater once I put a fan behind it. Only thing I then had to worry about was to keep a door cracked to make sure the shop got adequate oxygen. I didn't need to kill myself from carbon monoxide poisoning. The other problem I found was that the shop smelled of burned propane then, it wasn't bad, but not pleasant either. Once I moved to my new place I got myself a little bigger shop. Now I have one about the same size as you, 22'x 22'. I used the propane heater for a while and it worked great, but then I decided to give a buddy's kerosene heater a try. It worked fine, but I hate the smell of burned kerosene so I didn't use that very long. Then my father built himself a new house, and I inherited his old wood stove. I installed that, and it worked wonderfully except for one thing. When I wanted to paint something I had to go back to the propane heater only. I didn't want to run the risk of having the woodstove cause an explosion. I couldn't just turn the woodstove off and on easily like the propane heater. Even when you think there's no embers in the woodstove, you don't need to take that chance. I worked like that for a couple of years. Using the propane heater when painting so I could turn it off to paint, then back on after I got the shop cleared of paint fumes etc. ( And I do mean WELL cleared of FUMES ) Two years ago I had an HVAC buddy give me a natural gas furnace out of someone's house. I installed that ( in a room outside of the garage walls ) so the furnace was isolated from the shop and all paint fumes etc. So now I use the furnace in conjunction with the woodstove. But I still make sure the furnace is off when painting, I respect the fact that I can't outrun and explosion like they do in movies ;-) The furnace is used mainly to keep the garage at a constant temp. or if I am just going out there for a couple of hours. The woodstove is used when I am going to be out in the garage for a while and to save me from really high natural gas bills ;-) Plus it gives me a place to make my mistakes disappear. Hope this helps.... just make sure whatever you use to heat with that you work safely around it. You only have one shot to get it right, mistakes with flames can be deadly. Todd PS: If you install a wood stove make sure your insurance company knows about it, otherwise if you have a fire they WILL NOT cover your losses. Plus they will insist on having it inspected, which makes sure that you installed it properly.... good for your peace of mind too.

Then took the new ones to a Chevron station nearby to fill them, $2.13/gal, plus tax, almost $23 for both. Sure glad I don't own one of the old smelly super inefficient always freezes up in the winter propane vehicles. As for a shop heater, my son had one that screwed onto a propane bottle. The screen mechanism on the unit broke and the flame was uneven and popped all the time. Unsafe so we scrapped the entire unit. I'm uncomfortable myself with an open flame of that type in a small wood shop, plus the carbon monoxide etc so I use an electric radiant heater mounted to the ceiling joists. Grandpa John |

If your shop is free standing and you have either natural gas or propane available in your area, I'd recommend a gas fired Modine (or modine-type) heater. The unit would hang from the ceiling above the work area, is fan assisted, and can usually be hooked up to a thermostat. My first choice for a shop where comfort is not top priority. A local Plumbing/Heating contractor would be happy to help ;-) I bet the following link has some more stuff about it, but I'm too tired right now to look at it myself: http://modine.com/english/index2.php...lev1=10&lev2=5 |

I'm not sure if I understand the question completely. When you say open
flame are you referring to the various heaters with an actual flame that's exposed only, or are you referring to woodstoves also? I don't see a problem with woodstoves--we've used one for my whole life, my father's entire life, my grandfather's entire life, his father's entire life..do I need to go on? Plus you've got a great place to dispose of cutoffs and sawdust. ![]() Dave Rathnow wrote: With winter immanent, I'm looking at putting some heating in my shop so I can work and not freeze.

Even a store that is supposed to be "out" can still have glowing embers a day or two later. It is against the National Fire Code to use solid fuel heaters in garages due to the potential of having gas fumes from an automobile. With proper care, it should be safe as any other heater. I use an open flame propane heater, but I don't spray finishes while it is still running. Ed http://pages.cthome.net/edhome |

Electric is expensive to run, but more of a cost of running enough power to get enough heat. A 1500 watt heater is only 5118 Btu. I need at least 30,000 in my detached garage. When the temperature gets very low, say 20 degrees or less, I don't even try to heat the shop. What is best for you? Depends on many factors. Insulation? Coldest outdoor temperature? Fuel availability? Ed |

I have a 50x50x14 shop and plan to heat it with three 6x12 panels this winter. Last winter I used a single 6x12 panel to keep shop temperature above freezing; and estimate that three will provide a comfortable daytime working environment (most days). I don't know about your locale; but a shop the size of yours here could probably be kept decently warm with a pair of south-facing 6x8 solar panels. The advantage, of course, is that there isn't any fuel requirement. -- Morris Dovey DeSoto, Iowa USA |

I've started reading AFB, and have been trying to decide how to augment the gas grill with a slow wood burner... I've posted this one before, but since you have a group of 60 coming, will post again. Doubt you can get a typical propane grill low enough for this one, so will give you the oven recipe: Lew's Country Ribs Start with at least 5 lbs of "country ribs" usually cut from the shoulder of the pig. (These are the fat ones and around here they are $0.99/lb on sale) Put ribs in a 1 gallon ZipLock bag along with 1-1/2 cups of soy sauce and 3/4 cup brown sugar, mixed before adding to bag. (Scale up as required). Marinade ribs for at least 24-36 hours in the fridge turning over every 12 hours. When complete, place ribs, fat side up on a rack in a pan and place in oven @ 400F for 20 minutes, then reduce heat to about 212F (halfway between 200F-225F setting on oven) for at least 10 hours. Save marinade for later. Remove from oven and allow to rest on cutting board about 20-30 minutes, then cut 1/2" thick medallions of meat with a good sharp chef's knife. Any bone or residual fat can be peeled away with your fingers as you are cutting medallions. You end up with only lean pork pieces. Place marinade in a sauce pan and slowly bring to a boil over low heat. (You don't want to caramelize the sugar) Arrange medallions around the outer rim of a serving platter with cup in center of plate containing sterilized marinade. Add tooth picks and for your own safety, get the hell out of the way. Enjoy. BTW, I'm doing these for a party this weekend. -- Lew S/A: Challenge, The Bullet Proof Boat, (Under Construction in the Southland) Visit: http://home.earthlink.net/~lewhodgett for Pictures |

With winter immanent, I'm looking at putting some heating in my shop so I can work and not freeze. I've heard people say that any kind of open flame heating is dangerous because it could ignite saw dust--I've heard others say this is rubbish. Could people share their opinions and advice? Is an open flame heater dangerous? What type of heating do you use? Any recommendations to heat my shop: it's about 20x20 with a 12 foot ceiling. Thanks, Dave. I've used a combination wood/coal stove for years. Wood in the early fall and late spring to warm things up then the heat of the day is sufficient to keep the temp comfortable. Coal in the cold season on Cape Cod...it's cheap, easy to use not having to feed it often. At 10pm, I feed it and its good until 8am the next morning. Shop temp about 70F. Never a problem with dust although I keep a clean shop. |

I'm curious as to how you distribute the heat in your shop. I've been
giving a lot of thought into putting in a solar powered radiant system when I build a new shop "sometime." But how do you add solar heat in a pre-existing building?

Last winter I used a single 6x12 panel to keep shop temperature above freezing; and estimate that three will provide a comfortable daytime working environment (most days). I don't know about your locale; but a shop the size of yours here could probably be kept decently warm with a pair of south-facing 6x8 solar panels. The advantage, of course, is that there isn't any fuel requirement. |

Just a note: I refilled two gas grill bottles Monday at $2.19/unit, 7.7 units. (I don't recall if it was gallons or pounds.) About $18 & change. In California. At ACE Hardware. If that is for both, not a bad price. Tonight I filled mine at BJ's for $7.49. Non member price is $12+ In the course of the winter, I use maybe 4 or 5 bottles. I haven't filled mine in a long time, so don't know prices, but I do know my shop, which is 25 x 48 with an 8' 6" ceiling (I screwed up the 10' would have been much better) flat eats propane on cold days. I have a 35,000 Btu catalytic heater and a 15,000 Btu model, and often had to run both to get it up to working temp in the a.m. Working temp for me is around 55-60, but if I'm gluing it is 65 to 70, as it is for finishing. But I don't like spray residue floating into glowing catalytics, so I ran it up near 75 or sometimes 80, and shut down the heat before finishing. That eats at least a 20# bottle (4 gallons?) each day. This winter will be cheaper, if all goes well. Set the furnace at 50 and leave it until I'm in the shop. We'll see.

I'm located in Calgary, Alberta, where winter temps can get down to -30C.
Average temps, though, are usually about -15C but we have these things called Chinooks that will causes temps to go from -20C to +5C in a couple of hours. Where can I find more information on the solor heating panels you are using? Thanks, Dave. "Morris Dovey" wrote in message ... "Dave Rathnow" wrote in message news:OZ3Xc.55635$X12.38428@edtnps84...

Thousands of woodworkers both professional and non have burned firewood in their shops since forever. There has indeed been a great deal of discussion surrounding this and in fact a great deal of real fact. In the end, you won't be able to create the type of air/fuel density necessary for combustion with your shop tools. You can do a google search and find the reports of exactly what particulate count and what size the particulates have to be in order to support combustion if you choose, but you'll find that you really can't create that environment. Maybe _you_ can't create a pile of sawdust, but if so you are the only woodworker in the world who is so blessed. One does not need airborne particulates to have a fire you know. True - but to keep this on the track that it started out on, I was not talking about whether sawdust is flammable or not, I was talking about explosive, which is what I interpreted the OP's question to be. I elected to let the obvious stand on its own, which was that sawdust will burn. I gave the OP credit for being smart enough not to throw a pail full of coals into his sawdust pile, which is just about the only way he's going to be at risk. -- -Mike- |

I have a 26x40 shop that I heat with a propane 70,000 btu furnace.
It's made by Modine and it's called a Hot Dawg. It hangs on the ceiling and vents out the wall. I bought it on the internet through QC Supply for around $600 delivered. I did bring in a 320 lb propane tank that's only used for this furnace, then it's easier to gauge how much I'm using. Last winter (in northern WI) I used about $300 worth of propane. When I'm not using the shop I keep it set around 45 and it takes only a few minutes to heat up to 65. |

link.net: I've posted this one before, but since you have a group of 60 coming, will post again. Doubt you can get a typical propane grill low enough for this one, so will give you the oven recipe: Lew's Country Ribs snip of a good looking recipe Thanks, Lew. I'll almost certainly use this approach for at least part of the feast. Enjoy your get together this weekend! Patriarch |

Phil,
Don't have room for {and can't AFFORD} one of those 'traditional' pot belly's. So I have a cheap 'knock off' of the 'Swedish style'. Ditto on what I feed it . . . along with chunks from a tree I had to take down years ago. Actually, a bit better than a portable Kerosene heater. While the Kero heater puts out 120,000 BTu, one of the by products is a slight amount of water vapor. Not the best for the tools or the curing epoxy.

Phil,
I keep hearing references to 'cheap at the scrap yard', and 'shopping' at the city dump. WHERE !!?? Around here you'd think the stuff was either gold or nuclear waste . . . the way it's either locked away or trucked a hundred miles away. If you don't get it out of your neighbors trash before the Thursday morning pick-up . . . it's GONE !! Regards, Ron Magen Backyard Boatshop {That's how I got the doors that make up my heavy *big* workbench, and what I throw across sawhorses for 'instant' ones !!} "Phil Hansen" wrote in message ...

Same as here. "The city dump" is off limits to anyone that doesn't work
there. We have "transfer stations". Open top semis that you approach from the top via a platform and throw your stuff into. Not much of a way to salvage anything. If you do manage to salvage something, you will be arrested for doing so.
