Ceiling mount heater

-
I just installed a big max in my garage this weekend. I don't have easy access to gas so I converted it to propane. I'm not super impressed with the heat coming out of it but I do need to adjust the gas pressures as it's different for propane. I'll give a better review later this week when I finish it.

Here is a floor heat boiler system I installed last week. This has 30 runs in it.

Coal is the warmest, steadiest heat you can find.

We heated with coal until I was about seven. My Dad always bought PA anthracite coal...good hard coal kept a good bed of coals.

I remember when he bought an automatic stoker so he wouldn't have to go in the basement to shovel coal during the night.

We'd open the windows in zero weather if we got too hot.

I have a gas fired radiant tube heater in my shop. I'm not using it because the gas company and I have a $900.00 dispute over a past gas bill.

For the last several years I have used a pellet stove to heat the shop. If I have let it get cold inside I warm.up the space with a 30k propane torpedo heater then the pellet stove can keep it warm. It's only a 25k btu stove so it would take a full day to warm the shop without help.

You can not simply adjust gas pressure, you must generally change the burner orifice(s) size(s) as well There should be a kit specifically for that from the manufacturer. Generally, it consists of a different spring or regulator top plate for the gas valve, and different orifices for the burner. There should be pressure readings on the heater nameplate

Yes, I know...... This is a standard procedure when switching from gas to propane.
I've changed the orifices in the burner and also set the inlet and manifold pressures. Also don't forget that propane and natural gas are different settings so you'll need a manometer to set these. A pressure regulator is needed minimal 11 wc maximum is 14 wc. Manifold pressure needs to be 10wc for propane and 4wc for gas also depending on your altitude. And don't forget to change the gas valve spring along with the regulator adjuster screw with o ring.

In the process of doing a much needed makeover inside my shop/garage and I'm looking at the Mr Heater Big Max unit (ceiling mount) heater I have fairly good insulation and it's 24X40 with 8 foot ceiling any experience with these or suggestions

I have the 50,000btu in my 24x32 shop running natural gas. 9 1/2 foot ceilings, fully insulated. I leave it at around 42F when not in use. When I go out in winter I bump it up to 64-65F and it warms up to that in about 15 minutes. Love this heater. Moves a lot of air and throws good heat. Have had it for the last 4 years and no issues so far. I recommend this heater as well

Note: Cord and wiring have since been tidied up. This was right after final install
 
I'll tell you what not to get: A NewAir G73 electric heater:

https://www.amazon.com/dp/B000TK2SWO/?tag=joeychgo-20

My shop is about 850 square feet with 14-foot ceilings and quite well insulated (5/8" drywall over R-19 in the walls and R-30 in the ceilings. The NewAir heater does not warm the shop up very well at all, and it is quite expensive to run, so I no longer use it. (Although this heater is rated for only a 500-square foot room, with all the insulation I've installed I think it should do somewhat better than it does.)

I put ceiling mount LP furnace in my shop four years ago and never looked back.
They are available thru Northern Hydraulics.
 
I have a Modine, 60,000 BTU,Natural Gas Unit. - My garage is 28 X 40 Ft., with 9 Ft. ceilings, and the unit does a great job, here in N.E. Pa.

Yeah.... that's like three small hand held hair dryers, three. You are gonna need a little more than that!

Yes, Lefty71, no doubt you are right, but despite its failure to heat it increased my electric utility bill a lot!

It must cost an absolute arm and a leg to heat a shop with one of those great big electric ceiling heaters that you see occasionally.

We don't have any natural gas in the area where I live, so the only alternative is propane, which is in high demand and is therefore somewhat expensive.

Happy with this in a 24x 28 shop. 2x4 walls insulated and dry walled. 10’ ceiling.
