Question: where do you get a natural gas tank to use with this heater?
Document: My mistake. I oreded the wrong one. Make sure you order there correct one. One can use a propane tank (like a gas grill and one can't)
There is a central heater in another part of the house, so I get some of that air coming to this room - but not much I tell you.All in all, it makes the room much more comfy, and helps me warm any part of my body I can get over the top of the grill.
We are in our second season with it. No problems. Its in our master bedroom which is at the furthest point from our main furnace so the room stays a bit colder than the rest of the house. We only use the heater a couple times a week since it is just supplemental heat for those extra cold nights, and then just to warm up the room before going to bed.
great works like a Mr.Heater should , easy to install if a gas supply is near , good price and fast shipping what can I say
First, this product is a great price and is made of metal - so I think it will last.Three reasons this only gets 3 stars...1) I had a Mr. Heater (the kind you go camping with) and it burned 99.9+% of all the gas and would heat up some kind of ceramic plate.
Be mindful that vent less heaters produce condensation regardless of insulation and as such require adequate ventilation to minimize moisture.Think mold, rusted metal power tools, and ruined sheetrock.They are NOT a 24/7 primary heat source.My suggestion is to do a search on 'vent less heater moisture problems' BEFORE purchasing. My mistake was in not researching this project.I plan on replacing mine with a vented heater.I use it sparingly in my 10x20 workshop until I can install its replacement.
I needed another 1/4 turn so the unit would sit flush against the wall. Anyway, the metal is a little weak there.Also, when you install against a wall, there are two screws you had to put from inside. My drill was a little too large and they could have given that area more room as well.3) EfficiencyThe other Mr. Heater had less of a smell as the gas burned.
I bought this small 10,000 BTU ventless space heater to keep a small sunporch warm. It does the job in Ohio in early December, set on LOW. No problems with the product, or Amazon. Good value for the cost. PS - I'm using "well head" gas from my private gas well, which the manual say's is a no-no, but no problems... a nice blue flame.
The pilot light will not ignite on this heater. I have a feeling that it is a common problem because "Won't Ignite" is the first thing on the FAQ list and the factory automated phone system even asks you to press a digit if you can't ignite your device.Working with gas appliances is not new or strange to me. I have good NG gas pressure. My lines are spotlessly clean and everything is installed to code and in accordance with the manufacturers directions.
This would be a five star review if the description were accurate.The description says it has a thermostat. There is none. It simply has Low and High, and you can get some variations in between.
Answer: There's no tank, it's not propane it "natural" gas - coming from the gas mains in my home.
