[1bad79]

I need a new furnace for my shop,mine caught fire and almost burned the place down. I need a hanger natural gas, so what do you have, how old, would you recommend it? What brands to avoid? Thanks

I have a house furnace. 70k btu for my 24x34 shop. Works great for me. Luckily I know an HVAC contractor so he got me a used one for $200 and installed it for a case of beer

I got an old *ss DuoTherm downdraft oil furnace in my garage. When it works, it's great! I'm guessing it's late 50s/ early 60s vintage.

How big is your shop including ceiling height?

30x40 11 foot ceilings I have a 90000 carrier and it worked great until this week lol I’m just glad I dident loose my shop

That's scary stuff. Fire is my primary shop concern. Glad nothing/no one was hurt.
Cubic foot wise that's pretty similar to my old shop. I bought a waste oil furnace and it was waaay overkill for the space but otherwise awesome. Sorry, I really don't have any natural gas related advice.

Radiant. Floor. Heating.

It is really cool because the heat transfers into everything that touches the 28x40 slab. Even my tools feel warm.

I keep it set at 57*F, and supplement with a heat pump/exchanger if I want forced air. When you have a 75*F temperature differential between the elements and the shop - it feels quite warm.

In the summer it is the heat pump, a window unit, and fans for the AC.

If I build a new house/ shop this is what I would do I think

Radiant floor is awesome! The down side is paying for it. Both the initial install and the fuel costs. You have to keep the shop heated 24/7 during th cold months, that's the only way that style system works. I'm not working out in my shop every day, sometimes not for a week. That's a lot of wasted fuel when I can keep it at 40 with a furnace and in 30 minutes have it at 65 degrees, then a few hours later, turn it back down to 40 so stuff doesn't freeze. JMO

I've been looking into them the last couple months. Reznor is the top dog for shop heaters. Very few problems, good customer service but you pay for it. Mr. Heater brand is exactly opposite. Cheaper initial cost but problematic. Modine is middle of the road. They have 100k btu units in either brand. The Reznor is 83-84% efficient vs 80% for the other brands which makes it qualify for energy credits if that is important to you.

I'm saving for a 150k btu Reznor for my new shop.
