Anyone have good recommendations for a decent heater for the garage? Needs to be 110v

I know you said no 240v. But it would be worth running some wire to be able to have a mini split/heat pump. Heat and cool and dehumidify in one setup.

Not only that but then he'd have 240v for tools.

Like couple others here, I use a a Dyna-glo Pro 80k forced air on kerosene.
5-10 minutes and the garage gets pretty toasty.

From my experience- Something I had this over the work bench which is best I think you can have with 110 limitations- you can go 220V but for me wiring the circuit and paying the electric bills that is a no.

Edit: I see a rickyd comment on a heat pump. Another body has this in his well insulated garage- blocked off the third bay. It was nice to have the cooling in the summer for sure- don’t know if he has enough heat yet.

But to heat- you really need BTU's- propane I have this- Propane heaters are probably the least expensive buy in and useage

In another space I have a 30,000 BTU pellet stove that I seasonally vented out a window- this probably the cheapest to run but more costly upfront luckily I found a used unit

If he's in town, a NG heater is pretty inexpensive to install and to run. That's what I use...65000 BTU and I only bumped my gas bill by 30/40 dollars a month...and I'm heating a 24 x 30 two story barn with it.

as an example

Mine draws combustion air from outside too, so I don't have to worry about a big ka-boom! when I'm making fumes or doing anything that releases a lot of fine dust.
I have this heater in my garage, but it runs on propane. I typically only heat my garage when I have projects going on. When it's below freezing outside, I turn the heat on in my garage and only have to wait about 10 minutes before it's comfortable. My garage is insulated, but only R19 walls and ceiling.
 
i have a 20ft. shipping container that i insulated for the harley’s. i use a portable propane heater that’s made for an ice fishing hut. only use it when working on the bikes during cold weather and it will run you outta there in just a few minutes on high. i need a proper shop for jeep projects.
 
I use a propane cannon style heater. 10 minutes in my 2 car and I'm in a t-shirt. Only have to run it for a few minutes every hour or so to maintain.

Is what you use something like this?

Mr. Heater 125,000 BTU Forced Air Propane Heater F271390 https://www.amazon.com/dp/B00KRFVG5G/?tag=wranglerorg-20

How many BTU’s would I need for a normal 2-car garage with 8-ft ceilings? 35,000? 60,000? 125,000?

I only heat the garage for intermittent use.

Depends on your climate zone...

For warm climates (climate zone 1-2), most HVAC people suggest 20 BTUs per square foot. In colder climates, say climate zone 4-5, most suggest ~50 BTUs per square foot. In super cold places, climate zone 6+, it can be up to 70 BTUs per square foot.

Pellet Stove. Can vent out the side or up through the rough. Dry heat. A ton of pellets are about equal in price to a cord of firewood dry, cut, split, delivered (in my area). Pellet stove can be hooked up to a thermostat for on demand heating.

Edit: Depending on the type of the clearances you need for the sides are less then a woodstove. Chimney is smaller also.

I've thought about a pellet stove, the initial cost upfront is big but they do work really well if you can afford to lose the ground space

Are those numbers based on interior? Cause if you need a garage heater in zones 1 and 2 you might be a weenie.
 
If all you have is 120v, just buy cheap utility fan heater for $30 or less and place it so that it blows right on you where you are working.

If you have two circuits, you can get two heaters and double the output and have them both blowing right at you.

I have a 5,000 watt 240v heater that is portable and makes a big difference compared to a permanently mounted electric heater...because you can aim it right where you are....right under the car or wherever

haha don't know man - when I was in AZ, our garage was insulated but not heated. It was plenty f*$@%*(g cold in the winter on that concrete floor! Definitely thought about a small space heater a few times and did drag my little mini heater out there on occasion
 
I live in zone 3 , in the winter I have to go from flip flops to shoes and socks!🤣

also Zone 3 here (OKC's avg daily low in January is 29 and high is 50), with an insulated garage I do ok without a heater just wearing some thermals under my jeans and my Dickie's long sleeve work shirt on the coldest days. I also use a rolling creeper so I'm off the floor, and my garage work is all hobby so if we get an uncharacteristic cold snap, I can just take a day off. I'd probably want some heat for occupational use where I was in there daily, especially if I was moving vehicles in and out through an open door.

Now, when I was building my LJ in the evenings through a Zone 5 (17-40° average January) winter in an uninsulated garage is when I got the Big Buddy and an adapter to attach it to the tank I use for my grill. I set it up facing the area I was working in but far enough that I wouldn't bump into it, and I'd usually end up turning it off after an hour.

I use one of these as well with the same experience. I was surprised at how fast it heats up a double car garage in the winter.
 
Anyone a fan of a waste oil heater? They seem to have a bit of a price tag, but if you don’t have natural gas are they worth it? Or is it easier to just jump off the kitchen and laundry propane tank and go gas.
 
I snagged a forced air propane on FB for $80 vs Amazon $170. It’s fine except two things. 1. It’s loud. 2. I have to leave the garage door cracked to vent the place, which is counterproductive.

I like the idea- for me I am not sure if i would generate enough waste oil to get through a winter. Every oil burner system I have seen can really put out the heat.
