Question: Can you start the fireplace without electric, good for heat during power outages?
Document: With the blower running, and the house not freezing (50F+), the fireplace produces enough heat to run you out of the house quickly. In the event of a power outage, it takes about an hour w/o the blower (which requires electricity), using natural convection in my home (semi open architecture, 8" ceilings, one story 3 bedroom, 3 bath house) to get the common areas above 75F (which feels pretty warm to me during the winter).
Our heat pump does not give the &#34;warmth&#34; that we desired. This gas fireplace does the job. We couldn't have made a better purchase for our home. We have a small home and this little bad boy heats up the whole house. It is beautiful as well. We have had plenty of compliments on it. The built-in thermostat is a great feature. I would recommend it.
I bought this model for the front room area (living room/dining room/kitchen) and a direct vent for my bedroom at the opposite end of the home a few years ago to serve as back up heaters in the event of a power outage. I don't regret the decision one bit. This unit, Kozy World Windsor, came with a different exterior but the inside (black part in this picture) is the same.
My initial concerns were:  1) ventless fireplaces directly exhaust into the air in the home and 2) these units might burn up all the oxygen in the home further decreasing air quality. These have O2 sensors that prevent this and I've never noticed any air quality issues. I also learned that the primary byproduct of burning propane is water vapor which makes these a humidifier of sorts. This a good thing during the winter in my opinion.
I bought this heater for a new addition. Came at the perfect time, very cold weather. Looks nice and does a good job at heating the space. It arrived with all the screws missing from the top section of the insert. I found three of them in the box out of 6 or more. However, the holes were all stripped anyway so the screws were useless. Also the ignitor doesn't work. Button won't even push in, poor construction. It looks OK, nothing spectacular.
We get lots of compliments on the looks of this fireplace. Plus, it shuts on and off as needed to remain consistent temperature. Very pleased!
Not overwhelming in size, buts puts out a ton of heat! We put it in the basement family room, and, since heat rises, it heats the entire first floor as well!
We installed this stove in our log cabin as a secondary heat source. It has performed great. The thermostat control really make this stove a great deal. It will keep the cabin at an even temperature with no work from us. This is a quality stove and it looks like it was built for the cabin!
Despite it's excellent performance, I do not trust any vent-less fireplace enough to use the thermostat feature like I do with the direct vent I installed in my bedroom. Although I have friends who do trust them, I prefer to manually turn it on (with the remote or the control panel on the unit). That being said, with 25,000 BTU, it heats the common areas of my house fast enough that I'm comfortable doing so manually.
Item was not what I was expecting. The stain color is off from the picture and it even may be that the "wood grain" is actually a sticker, not even veneer. Screws do not hold up well in shipment, tearing insert from mantel. I would recommend seeing this item in person before purchase and picking up item in store as opposed to shipping.
Answer: It has a battery powered ignitor(AAA battery). So no electric needed. If the ignitor goes out a grill lighter will come in handy. It heats my single wide mobile home no problem. This winter has been much more comfortable than the last few. I have no problem keeping the house warm on frigid days and nights. One of the main reasons I bought it was incase of power outages. Hope this helps.
