shop heat

[longshot47]

My heated shop is a 28' x 28' section, which is part of a larger barn/garage. The shop has a 14' ceiling height over the main bench area and 8' over the remaining portions. It has an above grade, un-insulated concrete floor, 6" insulated walls [8" in ceiling], and quality windows on three sides. I was in there for a coupla seasons with various kerosene heaters which never really did the job, and were a PITA. While on a construction job I got to talking with an HVAC contractor who offered to stop-by to look things over. He recommended a propane furnace, and ultimately installed a 125K unit in the loft. Fabbed and hung two large, building width, wall mounted, runs of duct and a single return in the ceiling. It's been glorious ever since! The place heats from dead cold to 60+ in ten minutes and has been surprisingly economical to run. My shop cats send a Christmas card to the HVAC guy every year.

Zero outside, both ends of the barn about 32 degrees, with a toasty center.... that's shop heat... [ actually just checked, it's -3 now ]

Some of you guys' shops are better than my house.
A shop is like a bathroom. You may not spend all of your time in there, but when you have to go, the nicer the better.

LOL, ya, and no one likes a cold seat.

About to start construction on a 28x50 workshop. Have been searching for a cheap used Vermont Castings or similar wood stove on Craigslist. We used to have a couple of those in our house and i loved them.

30x90 un insulated steel Quonset. Home made wood burning stove.

Really only heats up the surrounding area in a 10 foot radius when its real cold out. But it is better than nothing.

All you guys with your free standing wood stoves. A small fan will help spread the heat a whole lot. A stack robber is good also.

We had a "stack oven" on our wood stove in AK. Seldom baked anything in it - too difficult to control temps for an extended baking period. We opened the door on the oven and let all the stack heat back into the cabin.

Gotta watch with the stack robbers.

Take too much heat from the flue and you have creosote problems

Instead of one of the heat robbers on the flue pipe, and needing a heat shield of some sorts to protect a post in the shop, I came up with this. A heat shield/scavenger combo. All made from some scrap pieces I had laying around, except the 140 cfm blower I already had, and still use on my forge, and, an adjustable temp. snap switch, to make it pretty well automatic on & off, eliminating a thermostat. I have the snap switch set @ 90ｺ. It will turn on when the backside of the shield gets to 90ｺ, and will shut off, when it gets down to 70ｺ.

Like in the past week, where temps were pretty frigid, and I kept it fired pretty good, it'd kick on every 5 minutes or so, when the upper flue temps stayed around 300ｺ - 325ｺ. That's the magic number it needs to keep a good draft, if there is little wind.

It could use a larger blower, but just using what I have. I just wanted to scavenge what heat that was there, and blow out across the shop, yet not stir up dust.

The last pic is the whole shop heat setup. The trusty ole' Reznor RA-110, 110,000 waste oil burner, vintage 1974. My oil refiner, made from a NOS upright air compressor tank, with two separate filters. First one contains a 200 mesh convoluted filter, to catch the solids, and the second, a standard HHO filter. to catch the non-desirable liquid types, like the Thompson's Water Seal a buddy left in one of the cans of oil he gave me last year, and gave me fits for 1-1/2 months last winter. Not the prettiest, but it ought to be between 54ｺ, and 64ｺ when I go to the shop here in a bit. I'll jack the thermostat up to a more comfortable work temp., and fire up the coal stove to hold it there the rest of the day.

well bought 2 7500 watt heaters from northern tool will install 1on each end of shop the one I installed yesterday blows hot air out about 15-20 feet should do the job thanks for all the info

 

[thepumpguysc]

Sure thing..
That's what I was thinking also, getting 2
its hard to beat 80.00 for a wall/ceiling mounted heater.
& w/ the 10-20.00 coupon its even more inviting.

I finally have heat in my barn! Picked up a couple Trane unit heaters (hanging shop furnaces) a few years ago, but just finally got it hooked up a couple months ago. Mine is a 150k btu unit. My overall barn is 40x62, but the main section that gets heated is 40x46. Still finishing the insulation and interior walls, but having heart is a beautiful thing! Also ran water, cable, internet, etc...

750 square feet garage. 1.5 ton Mini Split HVAC that keeps it nice and toasty in the winter and cool in the summer. When I added that thing it was like gaining 750 square feet of livable conditioned space that my wife stays out of.....best think ever.

I have pretty much the same setup, 750 sq ft with a 1.5 ton mini split heat pump. Comfortable year round and no messing with them, just set the thermostat and leave them alone.

I also put a 1 ton mini split in my wife's shop. Went with a couple of DIY units. Delivered and installed for less than $2K.

I've looked at those a little. Is the DIY 1.5 ton a 110 or 220? What brands did you use? Are your connections the couplers?

The 1 ton is 110V and the 1.5 ton is 220, both 15amp circuits.

I went with the Mr Cool DIY series from an HVAC company in Kentucky. They come pre-charged with 25ft linesets connected to the inside units. Quick-connects on the outside unit. Truly DIY, just mount it, connect the lineset and the wiring, and turn it on.

The outside unit is small enough to hang on the wall and they work great !!! Quiet and efficient, most of the time I have to put my hand up there to feel if the unit is running.

I also put a 2.5 ton unit in my neighbors garage and he loves it. He works for an HVAC company and this unit cost him half of what it would have through his company.

Cool....I am in KY, what is the company? I might have seen these before. Yeah, I think they come with like a 25 foot line set correct? What did you do with your extra length? Just leave curled up outside or what? These things are charged perfect for the length of line set you have so you can't cut it, I was just wondering what people did with the extra? People thought I was crazy but I seriously considered putting a .75 (9,000 BTU) in one a deer palace to hunt the early bow season in the AC.

I have a Pioneer from Amazon. I'm sure just a Chinese rebrand. I have had it a little over 2 years. 1.5 ton. My 220 was there already. Mounted on the wall and set the outside unit on the concrete adjacent to the garage. I did have to have a HVAC tech come out and pull a vacuum and make all my connections so I had a little cost...maybe $200. But the DIY is very very appealing. Even if the cost was a tad higher, the option to put these in yourself like you want, when you want is priceless.

Most people just coil the extra lineset.

You can see a video I did about them at Press Play Rewards - Jamie - Ingram's Water and Air - YouTube (got an extra rebate for that).

The 1 ton could be hooked up with a standard plug into a 110V outlet, but I would not recommend it.

Let me know how it works out. I am considering doing the same thing.

1000 sq ft currently with an oil furnace with an above ground tank. I plan on removing the furnace this summer and installing a pellet stove that has a 3 day hopper. The 3 days would get me through weekends out there or cold snaps with just feeding every 3 days. With our climate it doesn’t need heat most of the time.
