Question: Does this heater need venting outside, and does it work with propane?
Document: We are very pleased with ours. Right now it's 44 outside and 70 in our den with one burnner on. When you want instant heat to warm your feet while drinking that cup of coffee in the morning, it cant be beat.I much prefer the infrared heater instead of blue flame, there is almost no smell with these.Almost forgot to mention, very good people to work with, I had one defective heater and they promptly credited my account.
This is a very nice heater, its so nice that I had to remove it and put back the old one I had.So now it sits under my work bench until I find a use for it. :(
Not only is heater made chintzy, it does not work. I'll be sending this back for a refund. Replaced already with a store brand.I wish I could have given this zero stars.
I lower my home GFA thermostat and run the Kozy at night to keep out the chill. For long cold spells, I run the Kozy 30k as the primary heater. The Kozy 30K unit with thermostat really does not need a blower, because it really puts out the heat!
We replaced our gas fireplace with this heater. It is great. We have it outside in our three season room and it keeps it nice and toasty. Heats up quickly and easy to start too.
Mounted it on the wall in the 2 car garage. I have a cheap table fan on top of my beer fridge to circulate the air. Rarely have to turn the gas up past one burner. The only drawback was I had to mount it above my Kinnetico soft water system by the hot water heater (for the gas supply), and that makes me need a short stool to operate the controls . Would recommend this unit to everyone.
My basement is a large woodworking shop. I live in New England so the basement gets to be about 50 degrees in the Winter. I bought this heater to be able to work in my shop all winter. I have been using it for two months and needless to say it is doing what I had expected it to do. By Spring I will have all my new kitchen cabinets done and ready to put int place.
I got this heater at the end of November, I live in South Arkansas and last year's winter (2012/2013)was bad. I am doing some work on my roof and  I don't get wet anymore but there are someopen spaces and having the central heater will make may electricity bill  to hit $600 and the insidetemp of 67 digress .Since weather has been crazy I was expecting a bad winter again.
This heater is great. I live in michigan, in a 1,000 sq ft home.I put this heater on medium and my house stays at between 75 and 80 depending on outside temp. That's without my furnace running at all. I'm buying another one for my garage asap.
This was necessary to get my pipe aligned perfectlyand to support the unit so I could connect up the gas pipe to the 3/8 to 1/2 inch elbow reducerconnected to the heater female 3/8 inch connector.Since I have a clothes dryer gas connection that I don't use right next to garage wall,I connected onthat installing a shut off valve with T connector and plug (In case I need the clothes dryer connection later)I used 1/2 inch pipe through the wall.
Answer: yes
