Default Reznor V3 Tcore2 for garage or ,,,?

Hello Gents,

Starting to do my garage reno and need heat very soon.

30' x 22' with a 12' ceiling.

Will a Reznor V3 Tcore2 / 125,000 btu do the job or is it too much?

I'm told it is 3 years old (so 6 years lol) and came from a car dealership.

They want $400.00

Where would I mount it?

Thanks
Rod

The price is great for that powerful quality heater . . . . ie $400 for 125K Btu Reznor. Is that new or used heater??

However, you got any insulation?? If you do, then that massive heater won't run but a few minutes to heat that space. If you plan on opening and closing the door a lot, while also keeping garage heated, then such a massive heater will recover quickly, so probably fine. However, if garage is mostly kept shut, then that heater is overkill.

It's used. Commercial application, so well used.

Garage is insulated. How well I don't know as I just moved here.

The door is not opened very often, but as you can see I have a very big garage door that will suck the heat out.

Is this a quality heater?

They don't come up too often, and this one is for sale 5 minutes from my home.

It looks like it will have to go in the back of the garage as there is not much room on the sides of the door.

Since it looks like you have massive sectional garage door (12' x 16') . . . you don't have much available space for the heater on either side of garage door rails.

For your situation, best location is front left corner above refrigerator. Angle it in corner so it heats across garage at a diagonal.

I have 32" on each side of the door.
Maybe that is enough?

Yeah, the sizes are deceiving since you have such a tall ceiling and tall sectional door.

Optimal location would be on right side of outer edge by garage door (ie to the right in picture with car). Would be mounted on ceiling (ie 1" gap on Unistrut) at angle to blow heat into garage at diagonal across garage. Only problem would when garage door is open, the heat would be somewhat blowing on garage door.

I'm assuming this is a Natural Gas heater and you can route the NG supply line to either location?? I'd recommend black pipe steel that is sized plenty BIG to handle the NG draw from 125K Btu heater (like 1" depending on how long the run is from meter).

BTW. . . . beautiful Porsche. What year and model ??

The Porsche: 911SC or 911 Carrera, 1983-1989 is my best guess.

The heater: crazily oversized! Don't buy it!

Southern Ontario has a milder climate than the prairies where I live, and I heated a 22x24 attached garage with R40 ceiling and R12 walls with an insulated 16x7 garage door with a 4800 watt electric heater. It took a while to warm up from cold but it held the set point temp just fine as long as the door wasn't opened for a long time. That's 9.1 watts/sq ft.

You proposed heater is 125,000 btu/h input, I suspect mid efficiency or 80% combustion efficiency so 100,000 btu/hr output, which is 29,300 watts, or 30 kW equivalent!!! That can heat a 2 story house. That calculates to 44.4 watts/sq ft!

That heater will turn on for 3 minutes and be off for a very long time in winter, so all the hot air will rise, you'll be cold down at the car level, the heater will never heat up enough to burn off condensation which will rust out the heat exchanger and subject you to carbon monoxide poisoning, and it will use much more NG than required as it will never get to steady state efficiency.

You pay to play. Buy a single use load calc program and run the numbers, or have a good HVAC contractor come out and give you a quote. You would most likely heat your garage just fine with a 40-45,000 btu/hr input heater.

The Porsche is a 1986 911 Carrera. Lots of fun and sees around 15 days of track time each year.

Thanks for your ^^^ advice. That was pretty much what I thought, but didn't want to put out my opinion without hearing others.

Working down below with this much BTU I think I will be either freezing or cooking. When me and my buds come in off of our sleds the last thing we want is massive hot air blowing on us when we have our suits on.

I really want to go NG as I only want to keep the garage above freezing and be able to warm it up quickly when I need to spend time out there.

Agreed, 125,000 is way oversized for that space, you shouldn't need any more than 60,000 to heat it.

Thanks.

I'm looking for any advice even if it is not what I'm thinking.

A 75,000 btu unit has come up for sale even closer to my home.
He's advertising as new and is asking $650.

I don't see much smaller out there for sale.

Is this a quality unit?

I think 75,000 is too big for that size space, which will cause the heater to short cycle. My shop is 32x32 with un insulated block walls, 12' ceiling insulated @ about an R15' and my 60,000 BTU Reznor heats it fine.

Still having a hard time finding a smaller unit.
Looking for new it appears only installers are selling them and no retail.
Do they sell these retail in the US?

Yes, I've seen them on Ebay and I think ecomfort.com sells them.

Not sure if you have Menards up north but I have one of these for my ~ 1,000sq ft garage with 14 ft ceilings, well insulated and it does a great job plus the price is right. Good luck.

You used 45,000 btu for a 1,000 sq ft garage? Mine is 660 so I think that would work.
A bud of mine can get Hot Dawg at dealer cost so I think that is the route I'll take. You never know with the used stuff.

Rod,

My garage is very well insulated, has 14 ft ceilings, and a ceiling fan and shares a wall with the heated house. I keep the garage around 50 all the time and warm it up to about 60-65 when I am working, this usually takes 30-60 mins based on outside temp, wind and how warm I am making it. I was convinced I needed a 60 or 75 but my neighbor, an HVAC guy, told me 45 would be fine. He was right in my case.

And as a side note I live in far northern Illinois, maybe not as cold as you guys get but even in sub zero weather the furnace did fine.
