  • With the price of heating oil this is the ticket.
We live in a four bedroom two story home with 2 baseboard heating zones oil boiler. Even before all this stuff started with heating oil , we changed some things to adapt to the situation . 15 years ago we purchased a ventless fireplace for our 1 st floor great room that is fueled with propane , The thermostat is set at 50 degrees for the boiler. We run this fireplace fom 7;30 am to 10pm every day and that thermostat is set at 74 so its intermittent through out the day, That cost about $200 per month to run . We shut it down at 10 pm before we retire for the evening. The 1st floor boiler set always stays at 50. We have a corner doorway fan that circulates that heated air and it actually climbs up the stairway and keeps the 2nd floor at around 68 degrees with that themostat set at 55 for the boiler.Okay now we are getting to this heater . I had researched for years on approaches to supplement heating without defeating the costs, from trail and error and from the infomation I read on this heater , we deceided to purchase one. This is what we do... All the doors on the second floor remain open except our bedroom .This is the coldest room and sits over the unheated garage which I insulated about two years ago. We have a heatpump also in this area, but to be conserveative about that ,anything below 31 degrees is senseless , trying to hold a 68 degree temp...it will will heat but the interval between cycles is like every 5 mintues off and on off and on . This unit is shut down for the season.The thermostat for this unit and the boiler is in the hallway to balance all rooms .Now that it is getting colder around 28 degrees outside .. around 9pm the 2ndfloor temp is 68 I set the boiler at 70 with all doors open except the bedroom .I need the warm air to hit the thermostat for the boiler and with those other doors open this accomplishes that, I now set the Radiator unit at low Around 10 pm I setback the boiler at 65 degrees.The heater maintains room temparture at 70 degrees on low and as the night goes on it improves when the baseboards kick in at 65 . wake up temp is 75 in the bedroom and my themostat reading in the hallway is 68 with that set temp at 65.This is telling me that the baseboards are sustaining enough heat with the temps outside at 28 degrees to limit the run time on my boiler. My point is , i would have to run the boiler at 70 dregrees to maintain a comfortable heat in the bedroom, i can now run at 5 degrees less on the boiler to maintain the same if not better heat on energysavings mode. I was really impressed with a hallway temp of 68 degrees with that set boiler temp at 65 degrees. I may be able to set boiler at 60 degrees , we will see what happens What happens next am morning is, the honeywell is turned off and the boiler themostat is set back to 55. for the day. I go to downstairs my room temp is 53 degrees outside temp 27 degrees , i fire up the fireplace and the cycle begins again. I am happy with the results so far , was not fan of oilfilled rads in the past but tech has been improved over the years and , i have owned other honeywell products in the past & been pleased with their performance. ... show more

  • Toasty heater with great digital controls!
We got this a little over a month ago, primarily to provide a little bonus warmth in our basement office, which is open and significantly cooler than the rest of the house no matter what. Without a separate climate control system that is just the way it is! We had a similar unit that had worked great which actually belonged to someone else. When we moved we returned it, but that oil-filled heater was still working after 5+ years of use so we decided to go for the same style again for our office. Although I saw what looked like the exact same model for sale on Amazon, we picked up this guy for the slimmer profile, the wheels (we have tile floors and area rugs) and the digital controls. We couldn't be happier. This heater has warmed our chilly office area without increasing the cost of heating during this winter, because instead of overheating the whole house to slightly warm the office - we are efficiently warming at the place we need it most while keeping the regular thermostat down. We have used it daily since we bought it without a problem. PROS: -It warms small spaces (like bedrooms) super fast! Big spaces are slower, and open big spaces are slower still, but it's probably still cheaper than heating your whole house! -Nice digital controls. You can set the unit to Low or High (low being more energy efficient) or you can pick 65, 70, 75 or 80 degrees. You can also pick to have the unit run Low, High, 65, 70, 75 or 80 degrees - continuously - or you can set 2, 4, 6, 8, 10 or 12 hour timers. Although I can't say we use this at Low setting a lot (Low is basically going to be ~65 degrees), we are happy with it as it is, but you should know that is how it works if you are trying to be extra-cheap about things. -Sturdy rolling suitcase-like handle and decent wheels. The wheels could be better (i.e. larger and not plastic) but they work perfect on hard floor surfaces and they also work fine on my area rugs. The unit even hops up from the tile to the rugs with no issue. Now I don't have super-thick or shaggy rugs, but this is just an example for reference in contrast to the people who have posted that the wheels won't work on carpet. -Nice safety features. The unit will turn itself off if it gets too hot - or tips. Ours has turned off once when I was almost 100% certain that I hadn't set a time for it to stop running. This was midday, when I usually leave it running, as opposed to night time in the bedroom when I just want to warm things up before the covers get toasty! -Pretty safe to the touch - so good for pets or kids. Yes, it is a little warm, but for reference I just touched mine on the metal fin after it has been running at 75 degrees for the past 5 hours straight. Since the room is always cold, it runs fairly non-stop, but the metal is still not searing hot. I've touched hotter pan-handles that were supposedly safety-grip. My dog and cat checked it out and although they decided it didn't need a nose-on inspection, I suspect even a kid would touch once and probably not again, but if they did... no real big deal since this just isn't that hot. -Not very easy to tip over. My dog is blind and has tumbled into it a couple times when she wasn't moving slowly and didn't notice the heat before colliding with it. I saw the accident happen but the heater didn't knock over or even teeter, and of course my dog was fine. I can also wiggle it by the handle, trying to disrupt it, and see the heater is very, very stable. -Just generally very safe. The directions say not to use on or near carpet, but I've used one on carpet for years previously. I use this one with about 12 inches or fewer clearance from the wall and/or area rugs every day. The company has to cover their butts from potential accidents and from product misuse - everything is a lawsuit waiting to happen these days. But, oil-filled heaters are much safer in this regard than your normal coiled space heaters. That said use common sense like you would with a candle. Inspect the unit regularly and don't leave it unattended! I have no "Cons" for this unit, or for oil-filled heaters in general, but again I would suggest you always use common sense. Read reviews to gauge a product's general quality. Inspect your heater before using, during first use and on a regular basis. And don't just leave it running while you go to the movies. Things will probably be fine - no electrical fires and no spurting oil. Note: I find it sad that the most helpful review for this item is a bad one because the user didn't seem to know how the controls worked. If he actually set the unit to 65 the heater will turn off whenever the thermostat reaches 65 degrees. Now, it's possible he finds 65 degrees to be sweaty hot weather, but I find it far more likely that he looked at the thermostat reading of 65 degrees and set the unit to run on Low as opposed to seeing the thermostat reading of 65 degrees and setting the unit to 65 degrees. These are two different settings very easy to note the difference. Maybe he was just sleepy and grumpy? I just wanted to mention this since it is unfair the product is given a shining BAD review because someone didn't read the user manual, or even the easy to read digital dials. Maybe his unit from a year ago was very different, but mine looks the photo I attached to this review. Please see how there is a current temperature above the temperature settings you may choose. Also, note how at the top of the readouts you can see my unit is on "stand by" because the ambient room temperature is about 75 degrees. That means it isn't heating anymore, at least until the temperature drops. Hope this helps and Best of luck! ... show more

  • Older model was better
This sits in the closet. They older model works so much better and easier to set temperature. I ordered another for a different room and it just keeps running. Maybe the thermostat is broken?

  • great heater! but it failed, leaked oil after a few days.
heater is for an art studio; it was operational for a few days. nice heat, good size for heat effect (small unit heated the room well). a slow leak made a puddle of oil on the floor underneath, requiring returning this one. assuming the leak was an anomaly, i requested an exchange. i rate the amazon return / excbange process 10+ since the boxed heater was picked up by ups the day after the request was made and the new one will be delivered tomorrow--3 days later. ... show more
