This review is from: Mr. Heater 85,000 BTU Propane Forced-Air Heater #MH85FAV (Kitchen)

I needed a heater for my 30`x42` Workshop. In this shop, the ceiling is 16ft high at the center span and about 14ft high at the walls, so there is a large volume of air to heat.

The shop has 1.5" thick insulation before the steel siding. That's it. I also have sidelights that let the sunlight in. They run along the top edge of the 42' side so there is no insulation along those panels (about a foot tall x 42' long x 2 sides).

This is a great heater. You simply plug it into propane and an electrical outlet (it has a 3 prong 120VAC plug). There is no on-off switch so once its plugged in the fan and ignitor runs constantly, making a fan whooshing and then light buzzing sound. Turn on the gas at the tank, then push and hold the startup button - the propane begins to flow and it sounds more like a small jet engine (not unbearable or difficult to talk over from 10 feet away, but the wooshing sound changes to a deep throaty sound).

Low is the 50,000 or so setting on a red arrow dial. High gives you the full 85k. The dial is a quarter turn dial, and in-between settings do work also.

In my shop its hard to work unless its about 40 °F. I wear three sweatshirts and sweatpants, plus a stocking cap. The heater can get my shop from 30°F to 40°F in about 30 minutes on the low setting. Getting it up into the mid 40s takes about the same amount of time above and beyond the first 30 min (again on low setting). The high setting works noticably faster. After that I usually turn it off because with the stocking cap and three layers, it's bearable and easier to work.

When its colder than about 25°F outside I will often restart the heater if working for more than a couple hours.

A 5 gallon BBQ tank will last 3-5 hours and a 7 gallon RV tank will last 5-10 hrs depending on my usage.

Upon the first few uses I did notice a small leak in one of the factory tightened/sealed fittings near the regulator. The owner's manual clearly states to check all connections with a bubble solution (soapy water) but I didn't actually "had to" do that. I should have because I had a small leak. It was easily fixed with Teflon tape and has stayed sealed for years now.

NOTE: I do run a carbon monoxide detector in my shop, which is recommended since this heater burns the propane directly (no vent to outside air). However, running the propane heater for even a few hours does not trip the detector with my tall ceilings. Your "mileage" may vary so be safe.

I would definitely recommend this heater - its been reliable for three years or more and it works effectively.
