24x24 Garage Heater

[Kaoskido]

Hey guys ---

Minnesota and we are in the negative digits for the last two weeks......

Therefore I cannot use my Mitsubishi hyper heat and my electric Cadet Hot One 5000w heater is just not cutting it.

I am guessing that on these weeks of sub zero the only option to get good heat is a propane or gas heater?

I am curious to know are there any propane options that would be DIY or is all of the stuff with gas a hired out job?

DIY meaning about as easy as hooking up a gas grill... guessing not.

I do have a natural gas line in my basement for my fireplace and I don't think it would be too much work to get it into the garage. Of course, that would be a professional job. Just not sure how large of a heater would be needed and how much space would that take up heater including how much space it would need around itself.

I would get rid of the electric heater in lieu of a gas heater.

Just looking for options.....

Good thing is when the temps are in the teens both my current heat sources work good enough for me.

How is the 5kW heater coming up short? Not able to maintain temp?

I have a 24x40 metal building with 1 1/2" styro in the walls and 6" batts in the ceiling. I installed the 75k Big Maxx myself with help to raise it to the ceiling. I ran the piping for the propane tank my self, and the gas company ok'd it before filling the tank. The gas company had told me to install the propane tank at least 10' from the building, but when they came, he said the 120 gallon pig could've been right up to the building. Ten feet for larger tanks. It heats my building well, and I didn't care about short cycle, as it's not heated all the time.

Phil,
What temp do you keep the heat set at when you use it?

5kw should be enough in that space. How is it insulated? I'm assuming you leave it on full time.

I'm thinking you have an insulation issue. 5000 watts should be enough. I have a 7500 watt electric heater that I will run at 7500w for an hour or so to get up to temp, and drop it to the 5000 watt setting to maintain temp. My garage is around 20x28ish, 8' ceilings, R16 ceiling insulation, R13 walls, and above average air sealing (for a garage). I'm in upstate NY, by the way. No trouble getting my garage up to 65-70 with outdoor temps below zero, and I can do it at the 5000 watt setting (occasionally forget to change the setting back), it just takes an extra hour or so.

I'll echo this. I've got my heater set at 3kW about 40F, 5F daytime to -10F nighttime lately, not quite done insulating, R20 roof R13 walls. it's got no trouble heating.

I turn it to 5kW and 65F when I'm working.

I'm finishing a 24 by 40 garage and shop building, built with attic room trusses insulated with 3" spray foam in the walls and 4" spray foam in the roof, and I am keeping it in the 40s with two 1500 watt heaters set on low. I'm in western Wisconsin an hour East of St Paul. Today is supposed to be above zero for the first time in a week or so. I think the OP may have an insulation problem.

For the OP-
Maybe just a couple of grill tanks and a sunflower heater??

My mr cool hyper heat has maintained the FP setting of 45 this week

I have a 7500w electric unit so I can bump up the heat to work out there if needed

24x28 2020 build well insulated and sealed.
