Question: Would this heater be safe to leave on at nighttime?  It would be used in the kitchen.
Document: I was also able to leave it on for several hours at a time. It does draw a lot of power on the highest settings, so I had to turn it down or off when I used my hair dryer, but other than that, no complaints.
After realizing that our two bedroom apartment's electric heater uses 8000 watts and costs 80 cents an hour to run, I looked into a space heater instead. I ultimately bought this based on the reviews, hoping that it would be able to heat up one medium sized bedroom at a time and further hoping that it could heat our large combined living room and kitchen. After using this for a week, I can say that this heater is awesome.
Crap! Ony lasted 6 months! I got ripped off to begin with, it was priced at $90 dollars and now it's only less than $40! It only lasted for about 6 months! Even less than that if you think about it. I only leave it on for about 1 1/2 a day, and I would say I only turn it on 4 days out of a week in the past 6 month time period.
Purchased this heater after reading other Amazon reviews. Thought it said free shipping, but had to pay extra nine dollars. Very happy with the heater. Seemed to work better after two or three times. Heats my 10 by 12 basement room very well. Have not used the thermostat - either on or off. Nice and quiet. Would buy again.
I have used this heater every day of the winter and some days in the fall and I love it. I use it to supplement my AC because I am cold a lot and instead of heating the whole house I can just heat the room I am in. It warms up a 12x12 room in less than an hour. I love it. would purchase again.
I've used it quite a bit in my bedroom in the evening. I have no doors as I am restoring the house, so it heats quite a space. I have it set to blow on me while I watch stuff on my laptop. Keeps me warm-ish, which is what I expected given the openness of the space. I would buy it again in a heartbeat!
I would definitely recommend this black magic machine to anyone lookin' to heat up their huntin' lodge in the northern Yukon. You can even pick it up an' throw it at the bears when they break down your door (if you have it on an extention cord) an' they'll be scared right off like ptarmigans (apparently it's spelled with a p) from a yellow footed pussy willow in the spring. I even used it in my car!
It says it has a temperature regulation system. I would completely disagree. I ran this a year ago winter and it ran and ran and ran and ran and never quit. I used it for my baby's room since his room got super cold at night during the winter and it ended up heating the room so much that the poor kid was sweating all the time. I always kept it on the lowest setting but it didn't seem to help.
For a small room, this heater is ideal. Even on the low setting, it produces enough heat to quickly warm a kitchen or den.
I like this product very much. It has lasted us a little over 2 years and it does what it's suppose to do. It's a safe heater. It turns off if it falls our if something is to close to the vents.
Answer: I have had this heater for 2 years now and I rent out a room and it is perfectly fine to leave it on overnight I have done so on many occasions and never had a problem once.
