I am looking for a "ventless" propane type gas stove for our basement.
30x30 sq ft.
Northern tool sells a vent free for 500.00 and a "blue-flame" heater for 169.00
BUT, the heater says NOT FOR USE OVER 5000FT??
Does anyone use this type and any comments about the elevation.
The local propane dealer says he has customers that use them and they work ok.??
cannot put in a vented one due to the walkout basement walls.
One concern for the elevation is that the blue flame can snuff out, due to the lack of sufficient oxygen to burn. I live in Ohio so elevation is not a problem.
Good ones, like the Feature Comforts VENT FREE 10k BTU heater I bought at a Lowes for 130 bucks, have a low oxy sensor built in that shuts off the whole unit when low oxygen is detected, along with a 5 position heat set with thermostat. Uses either propane or Nat gas. Home Depot doesn't have anything close to compare dollar-wise with what Lowes had on its shelves.
Nowhere in the manual does it give any info on the limit of elevation that it can be installed.
In a 30 x 30 room you should not have a problem, but they don't recommend the use of one in, say, a bathroom or small bedroom with the door shut with no fresh air inlet, for your safety. Read the manual carefully when installing.
They do work well, I am placing one in my basement to take the chill out along with a room fan to mix the air.
Personally I would not use any non-vented gas appliance in a basement. I am very concerned with traces of Carbon Monoxide building up in the closed room. As CO is a persistent poison it can build up over time and cause severe problems even if people are not using the room continuously
Just (heh,heh) cut a hole through the basement wall and install a small stove pipe. A stove that brings in fresh combustion air is even better because there is no pressure difference between the inside and outside of the room created by the powered exhaust vent.
We took all of them out from the cabin. Where there is a flame there is carbon monoxide.
Check with your local gas person as ther do sell them for high elevation if this is the way you are going. We have installed a wood burner, and that heats the house quite well.
Those ventless heaters are illegal in some states -- which warns me off of them. Then you have a manufacturers warning for higher than five thousand feet.
That is a double warning -- I'd take them seriously. Think about what could happen if the heater malfuctioned.
Could you use electric? It shouldn't take much to heat a space that I guess is pretty much underground and is topped by a heated house.
As long you have monoxide detectors, there should not be a problem along with proper venting. High efficiency furnaces have a pvc intake of fresh air from the outside, so it would be good to keep fresh air where you are heating to err on the side of caution. My house was built in 1917, so there will always be some draft coming in.
There is usually a pretty good reason that a warning is put on a product in the first place.
Likely to keep the lawsuits to a minimum and to discourage "weekend warrior renovators" who may not know what they are doing.
