Eden pure heaters?

A little common sense and a little ventilation (included in the common sense guide book) is all that is required for me. Other experiences and environments may differ.

I have not had any issue with moisture. I have seen a minimal amount of condensation on the ceiling.

I do leave my shop open from time to time though at night when it is not raining so this may be why I dont have any residual moisture and we have a relatively dry climate here.

Of course plumbing the exhaust outside removes the moisture and other exhaust products from the inside and makes the heater unit about 10 - 15 x more expensive too. It will produce a much dryer atmosphere inside and if you live in rainy wet areas you probably will have to do this to keep the humidity and moisture abated (as mentioned by 67dart).

Have you seen this (pic below)? Many shops use one or more to heat their shop. I have personally seen at least ten paint and body shops with these running while general priming and spot spraying in the common area (in other words they dont operate this heater inside the paint booth). It has a forced air kerosene combustion chamber it runs 500+ degrees on the metal at the outlet. No issues that I witnessed in my 20 years of seeing them in operation. Noisy machines though. Sounds like a friggin flame thrower. This unit produces waste exhaust which is probably not the best for you either and also of course produces moisture as a byproduct.

My propane heater has a great ROI for fuel because it does not waste any heat. It applies all the energy of burning propane to the interior of the building. Total initial investment is 175 including a brand new tank full propane tank.

Just my opinion of course. :D

First that is an unvented open flame and can be VERY dangerous in a shop with stuff like fuel vapors, paint etc floating around

When I "was in heating" you had to have any combustion burner (I believe) 18" off the floor when installed in a garage. This may be more stringent in some locales and may have been upgraded since I was in this work

"Minimal exhaust." Propane does NOT create "minimal exhaust." While a PROPERLY working combustion appliance whether LP, gas, etc does not produce CO, it produces OTHER products which really aren't very good for you. Ventilation is important, and these types of heaters were NEVER designed for use in a closed area.

Also, these unvented heaters produce one HELL of a lot of water vapor, which when the shop cools back down, will condense all over everything cool.

Unvented appliances are illegal for use as room heaters in most locales, and for good reason.

Efficiency. Don't confuse "efficiency" with "cost of operation." This has to be figured as to the actuall usable BTU's output into the room, versus cost per unit of whatever, whether pounds of coal, gallons of oil, or kilowatts per orange juice.


All I'm saying is "BE AWARE" of what it is that you are doing, here.
