The EW7707CM Oil-filled Review For Holiday Deals

Don't get me wrong, this is a nice heater and works perfectly for our application (to heat our son's room which is located directly above the garage and thus colder than the rest of the house). I'll let the other reviews speak for most of the features of the unit.

What I do have a comment on is the ComforTemp "energy-saving" technology, which in my opinion, is just part of the whole green marketing fad. This includes making products/features appear to be green when actually they are not necessarily so. The ComforTemp "feature" does nothing more than override the thermostat dial and set the thermostat on the unit to ~70 degF. The box shows in big letters "27% Energy Saving," but if you read the fine print, it says "Based on internal tests on same model comparing energy using the ComforTemp function versus adjustable thermostat at maximum setting." So they are claiming an energy savings versus the maximum thermostat setting that would make the room way too hot. This is like saying a light bulb is energy saving because you turn it on only when you need it, rather than leaving it on all the time -- i.e., it only saves energy when compared to an absurd, high-energy-consuming scenario.

In our application, we actually save energy by not using the ComforTemp function, because we found that, with it turned on, the room gets heated to ~73 degF. We set the thermostat to a little above the "1" on the dial and that keeps the room at ~69 degF -- warm enough to keep our son from getting cold at night.

If anything, call the ComforTemp feature a convenience feature -- for those who don't want to bother with the adjustable thermostat. Call it a night light feature -- because it emits a significant green glow. Just don't call it an energy-saving feature. In my opinion, the best thing to do would be to remove the ComforTemp function altogether and just charge less for the heater! But of course the market research probably shows that if you pretend it's green you'll sell more units ... We purchased at the beginning of the year because the forced air heater we were using in our bedroom left me with headaches and a bloody nose and I was worried the same would happen to our newborn.

Upon reading the good reviews of this unit I purchased it and it worked great for the rest of the winter and chilly spring nights. I constantly had to turn the unit down because it was really warming up the bedroom.

But I just pulled it out for use about a month ago and it has failed to perform. I leave it on high all night and it still does not warm up the room. I have to run the other space heater along with it to warm up the room, then turn off the other heater before it gives me a headache. This goes on several times during the night.

I wanted to return it since it is still under warranty but DeLonghi says I have to pay for shipping it! This was a good heater, but it would be nice if it lasted longer then 11 months.
