[RCrosby]

hey guys, looking to get a good heater for the shop, 24ft x 24ft . looking at a 240 volts heater if posible,no gas at shop. shop is a wood build & siding. no insulation. what are you guys are using. thanks for any info

You say no gas at shop, but can you use propane. I have a propane radiant heater for my insulated shop.



My son has a diesel fuel with electric spark and fan like this for his shop.

RCrosby, how many watts do you need? I have seen 240 volts heaters go up to 4000watts. I'm not sure how high they are rated for. Just don't look at your power meter or you will get dizzy. LOL

I would suggest 150-250 gallon propane tank. It will pay for itself in a few years. You can prepay your propane in the summer when rates are lower.

A tip: A watt is a watt no matter if it is 120 volt or 240 volt. If you only need 3000 watts you could save money and buy 2 120 volt 1500 watt heaters for around $25 ea. Just make sure to plug them in on seperate breakers.

It did get cold last week.

I have one of these in my garage. I think it's around 20'x24', attached, insluated.



It's expensive to operate. And it takes a long time to warm things up. In fact, if it's below ~30°F outside I just don't work out there.

A friend has a 3500sqft garage with a 20'+ ceiling, and he has a small wood stove in there to heat things up. There is free wood everywhere if you keep your eyes open. I used to keep the last house warm all day with a couple of cut up pallets. A freestanding woodstove will pump some heat out.

I use one of these 100K BTU heaters on propane: LF24 Unit Heater | Heating Products in my 60' X 80' insulated steel building shop with 14' high overhead type doors. So far this winter, it's used about 30 gallons of propane with the thermostat set on 52 degrees.

This seems like a great idea, but you've got to exhaust it outside!

I believe it would take a long time to heat up a 3500 sq ft garage with a 20' ceiling with a small wood stove and then you'd spend all your time adding small pieces of wood to it to try to keep it worm.



Get a good propane heater like Bill Stockard's.

I have a 24X32' shop building with 10-1/2' ceilings and a 9X 16 garage door. Last winter, I insulated and finished the inside. I have a 75M btu Reznor heater running on propane. In reality, I could've used a smaller unit, perhaps 35 or 50M btu. Its 100 gallon propane tank was filled in September to 80% capacity, and today it is still at 34%. In terms of cost, insulation is your friend, espescially if you want to heat with electricity.

I have a propane heater that I use in my 2 car garage for woodworking. After all I have read about toxic fumes and the lack of oxygen from these open flame heaters, I have quit using it. As I understand it the only safe gas heaters are the ones that are vented to the outside.

Is this not really an issue?

It is an issue. Good point.



Propane heaters will work just fine, just make sure you have some ventilation and go outside often.

Just remember that gas fumes from a leak in vehicle or cleaning parts etc collect at floor and up some inches so keep heaters that could be ignition sources at least a foot or more higher.

How much did you give for that? A friend of mine has a propane chicken house heater in his shop. It does not have to be vented to the outside. He gave about $600 for it. My shop is similar size to yours (50'x90') so a similar BTU heater should work for me.

 

[Rattler]

I have one of those chicken house heaters in my shop. I just put it up and have not gotten my propane tank yet though. I think it will heat a 40' x 60' pretty well. It is rated 160k btu on low and 250k btu on high. Randy

If I remember correctly, it was around $1,000 including installation by a local licensed HVAC contractor. The heater has elecronic ignition (no standing pilot) and has forced air combustion chamber and is vented through the roof. With the forced air combustion chamber it can be safely vented through a wall. It hangs from the roof purlins in one end of the shop about 14' above the shop floor with the warm air aimed at the floor. When it's running, if I walk in the walk in door at the oposite end of the shop and I feel the warm air.

I have this 75,000 btu heater in my 30' x 40' garage. I fire it on propane and it does a very good job. I built my garage with 2x6 framing and it has 10 1/2 ft. sidewalls. It is insulated and sheet rocked, plus my three doors are also insulated. I got the heater from Northern Tool. The install should not be hard for anyone with basic DYI skills - I spent 5 years as an HVAC tech. , but these guys are very easy to install, so would not tell anyone to shy away. It is positive vent (has a combustion fan) and mine is vented horizontally. I put a metal roof on the garage and house when I built them and did not want any penetrations in the roof. It can mount 1" from the ceiling and the case is 17" thick. That leaves over 8 1/2' of headroom underneath. I have a toggle switch in my thermostat wire so I can cut it from running when I'm not using the garage. I could have used a low temp. thermostat, but am too cheap to spend the money. Right now, the 75,000 btu is going for $499. The 45,000 btu unit is on sale for $399. I think the horizontal vent kit is about $100. I have no interest in what NT sells or what other people buy. There are other products out there that are just as good. I'm just sharing my experience. Here is a link:

BSeyler, that looks like a nice little heater. I will have to have a little larger than that though, but like you, I do not want anything going through my metal roof (same way on the house) and I have run my vents for plumbing, furnace, clothes dryer and water heaters through the sidewall and up.

ALL fuel burning heaters and stoves need to be vented outside!! You can use a waste oil furnace if you have access to plenty of waste motor oil, a wood or corn stove if it can be set 24" above the floor. Or a combination! That also depends on any local codes.

I have a Reznor unit heater and a wood stove in my shop. The Reznor was originally setup to run on propane. It hangs from the cieling joists and is power vented along one side of the wall and out through a wall penetration, 25' from the heater. This allows most of the heat in the flue pipe, to be radiated inside the shop.

The wood stove is set on cement blocks, with the firebox being greater than 24" above the floor. It is vented through the cieling with standard stove pipe from the stove to a cieling support at the joists, then there is 12' of Metalbestos, class A, high temperature chimney pipe that goes from the cieling support through the roof jack. The shop is 1080 square foot with a 12/6 roof pitch. Inside, the ceiling is 10' tall. It is insulated and sheet rocked, except for the ceiling (17' to the peak). There are also (5) 2' X 4' skylights on the south facing slope of the roof. It has been my goal to finish out the ceiling but the roof needs repair first. Got the North facing slope completed last fall. That was the easy part GregH

I've got a Modine hot Dawg in my 20 x 30 insulated garage. Even when it's 5 degrees I can only set it to 50 degrees inside before I start to sweat.



The unit cost me $450. 00 when bought new in '02, but there still about the same price and the propane it uses is worth the quality time I can spend alone.



When we had just the garage on one tank, it went through 200 gallons the first (and worst weather) year.
