"will not stay on"
I purchased 2 of these heaters a couple of months ago. They worked fine for the first day and then they turned them selves off. I unpluged them, let them set for 1/2 hour and them turned them back on. Within a 24 hours, they turned them selves back off. I then set them for the lowest heat and within 24-48 hours, they turned them selves back off. I also noticed that when you plug them in, you could see sparks from the plug. The unit should not be drawing power since i had not turned the units back on with the on/off switch. During the reseting of these units, i made sure i did not touch the timer switch. I went to the Honeywell's site for further trouble suggestions but the site did not give me any more ideas than the manual.

"Works well"
We bought this during a cold snap when our furnace was down. It was the only model left in the store and I was leery of the controls (I worried they looked too complicated). It was actually really easy to figure out the controls, and it has worked great, as has every oil-filled radiator-style heater I have used. The oil-filled models are safer and quieter than other electric heaters. I like this one because it's nice to have the LED display of the current temperature. Otherwise, it generally operates the same as lesser-priced similar models. We've had it two months and haven't had any of the problems cited by other reviewers.

"Possible solution to shutoff problems..."
I started having the same problems as other people described, with sudden shutoffs, after about a year's use. On a hunch, I moved it to an open space, away from the two pieces of furniture that it was standing between, and the problem all but disappeared. I may be wrong, but the heater may have a safety sensor that shuts it off when there is a temperature gradient around it, indicating proximity to an object. (Or the heater's motherboard might have healed itself.) Addendum (4 months since my initial review): it may still occasionally shut itself off after a power-up, sometimes even two or three times in a row after a brief time of being on; but, after that, it stays on "indefinitely" - I left it on for up to 18 hours on several occasions without any problems. It is certainly annoying but only slightly in my case.

"not as reliable as one would think,,,,"
We too have had issues with our Honeywell Oil Filled Radiator Heater as it continually shuts off for no reason in the middle of the night but also continues to blow circuits on almost every area of our house when we have it running on high... Not the best invention by a long shot as it has a lot of bugs in it.

"Don't buy this one! Get the HZ-690 for $39.99 & save money!"
I bought two Honeywell HZ-708's last season and now they both won't stay on. They were great the first season but I bought them thinking that they would work for more than a few months. The company said that the problem is with the "mother-boards", but it actually seems to be with the digital thermostat shutting off the unit. I sent them back to KAZ (Honeywell) and requested they send me two replacements that did not have this problem. They sent me two HZ-690's. Now, these units do not have a digital thermostat nor do they have a timer. I liked both these features in the HZ-708/710 but the company obviously knows they don't work well and sent me the HZ-690's as replacements (without compensating me for the difference in price). So save yourself some money and buy the HZ-690 directly. (search for "Honeywell HZ-690 7 Fin Oil Filled Radiator Heater" - last I looked they were $39.99 vs $79.99 for the HZ-708).



I'll let you know next season if the HZ-690's still work.

Stay Warm!

November 2007 UPDATE. Our 2 HZ-690's (Honeywell HZ-690 7 Fin Oil Filled Radiator Heater) are still working beautifully!!! (fingers crossed). You'll enjoy the heat this unit produces. I wish the HZ-708 had worked out better but it seems the same eletronics issues still plague the newer HZ-709 (see those reviews Honeywell HZ-709 7 Fin Oil Filled Radiator Heater with Digital Controls) ... better stick with the low tech versions that are reliable. ENJOY!
