Have owned a heater just like this one for over five years now. It will not burn you, or a child, but gets very warm. With a box fan running quietly on low next to it to keep air moving over it, can keep three rooms relatively warm all night in coastal NC with one of these. It will drop into the teens here sometimes at night.
Feel safe with this heater for it would be hard to accidentally start a fire with it. Just ordered another one for I am going to let my LP gas provider have their tank back as soon as I use most of the fuel in it. Then, purchase my own LP tank. It's cheaper to use this along with my heat pump instead of just the heat pump alone. With LP heat for backup, Stay cozy no matter how cold it gets or if the power grid should fail.
Update: Do not understand the negative reviews outlining so many problems. Received my second oil filled heater, tested it for many hours and found it to work fine just like the one I have been using for many years now. Have owned many types of electric heaters. Like these oil filled units the best. Do not mind leaving my home with one running but it is definitely best to turn all portable heaters off when unattended. It has an overload/high temp automatic safety shutoff for safety. Use a 15 amp power strip on them with a 15 amp circuit breaker for extra safety.
Feburary 13, 2010: Both of my electric oil filled heaters are working fine as usual. Have had no problems at all with either of them. It's currently snowing outside tonight. Am using nothing but my two oil filled electric heaters with fans running quietly next to them to keep my home cozy- have shorts on. Propane prices are currently right high around here. Have plenty of propane gas on hand if the power grid should fail. My older model heat pump is not all that energy efficient. Like these cozy and quiet little heaters. Got another electric bill today. It was much lower than I thought it would be using these heaters with the thermostat on them set at a reasonable level.
Have popped plenty of 15 amp fuses and tripped breakers with 1500 watt portable electric heaters over the years. Especially in my motorhome. You can use a long, heavy duty, 12 guage extension cord with it on a 20 amp circuit- no problem. Don't use anything lighter than a short 14 guage cord. Personally, will not be using a 14 guage extension cord, of any length, with a load like this. Have spare fuses on hand unless you have circuit breakers or are using a 20 amp circuit. It's a pretty heavy load for a 15 amp circuit.
Dec. 7, 2010: Am again using my two trusty oil filled heaters with box fans quietly running on low next to them to keep my house warm. An Artic blast has hit early this year. It's cold outside. Have five smoke alarms in my home for safety. Am just wearing shorts as usual. One good thing about these heaters for me is that I can sit a stock pot, tea kettle or whatever on top of them in order to quickly get more moisture into the air. Just don't let any water spill onto the control unit side of the heater. Be forewarned that if you use a fan to increase the heat output and move more air through these heaters, you'll keep the heater cooler and thermostat energized putting out more heat in your home. Therefore, it'll use more energy unless the thermostat is set on a really low setting.
March 2012: Have gotten through another Winter with these same two oil filled heaters, saving significant money on energy in the process. Am quite fond of these two heaters. Feel safe with them and late model ionization AND PHOTOELECTRIC smoke alarms throughout my home. Photoelectric smoke sensors are important to detect slow smoldering fires before the fumes get you. If paper or something similar falls aganist the bottom of one of these heaters, it's just no big deal. Being able to use one with a stock pot of water on top of it to get more moisture in the air makes a big difference. Higher indoor humidity- at least 40% is MUCH better for the respiratory system in the Winter. When the water is gone, I can soon tell without even looking to see if it is empty. The water gets warm but not too hot to be hazardous to anyone. Just keep the water away from the control unit side of the heater.

Cannot even heat an 80 sq ft room more than 3 degrees F
This review is for the DeLonghi oil filled radiator space heater 1,500 watt TRH0715.I put this heater in an 80 sq ft room with a standard ceiling height of 7' 9". The specs on it say it can heat up to a 250 sq ft room. Well, I would certainly like to see THAT! Reference the chart I kept today. I turned it on this morning at 9:40am and left it on all day and took measurements for 10 hrs. I cranked it all the way up, both switches turned on and the temp control maxed out at 6, reference the pic.It took three hours to get this small room from a starting air temp of 72 to 75F. During this time, our house forced hot air furnace was also on and there is one hot air register in this room which is set for 72 and the DeLonghi struggled to achieve a three degree increase on a 40 degree outside temp day. What is going to happen when it gets cold out??? There is no temperature readout on this model so its anyones guess what the #6 on the dial translates to but that is the max it will go and with both switches on, it should be producing heat at its rated 1,500 watt level.Then as you can see in the chart, it did not maintain 75 degrees in the room, it fluctuated between 72.5 and 75 after hitting 75. I used a laser thermometer to measure the heating fin on the heater, always used the top of the third fin from the control panel for consistency. Those are the Heater fin readings in the chart. I could hear the thermostat click on and off so either there is something wrong with the thermostat on this heater or its capability is mislabeled or 75F is its max ability. This one is going back because I don't have faith that when it gets really cold out this winter, that this heater will even be able to sustain 75F.The good news is it is dead quiet and if you are in a very quiet room you can hear the faint clicking sound of the thermostat going on and off. The "new" smell dissipated within just a few hours. If this was more powerful it would be a nice heater. So who has any recommendations for a dead quiet yet powerful heater that runs on 120vac?
