I thinkm it is because in NA oil heaters are really not used much at all we either have hot water gas fired or electric . Is there a reason you need oil? Do you mean like the oil filled ones that we use for space heaters or oil fired like our gas fired ones.

Op is probably talking about these. I was very glad to escape those.

Yes, like that. Why did you not like them? It seems oil has some advantages such as more efficient, less noisy (I currently have De'Longhi "quiet" electric heaters that give off a high pitched buzz when NOT heating), don't "burn" the air, and more. I'm getting to the point where I might wall mount a portable oil heater.

"oil fired like our gas fired ones."

Huh?

And then there is, "mount a portable oil heater."

Once you "mount" it, it is no longer "portable."

Oh, where does the oil come from? A tank?

>Yes, like that. Why did you not like them?

Expensive heat, inefficient [it only heats up the area next to it], we installed them where the load is (under windows), here windows appears to be floor to ceiling. Dust get's on the back of those heaters....

I think it's easier, cheaper, and safer to distribute heat in the form of water from a boiler or air from a furnace than having oil lines running to multiple places for appliances that each need external venting.

They are sealed. No running oil. Electricity heats up oil tank that slowly releases heat back into a room. Used everywhere in EU.

But not in NA along with many other things that are in the EU but not here. I have to agree the portable oil heaters we have are not very efficient at heating large spaces which BTW we have more of than the EU I also have no idea why you would want to have wall mounted ones that require real hassle in furniture placement.

As Elmer said. Also, if you have any fuel-burning heater in a room, the exhaust must go somewhere!

Again, like BT said, no burning of fuel, no exhaust required. Why oil-filled radiator heater? As said before, more energy efficient, quieter, doesn't dry out the air (better respiratory air quality), longer lasting heat. I'm not seeing why it would be much more of a hassle to place an oil vs electric heater on the wall, both require stand-off distances of furniture, etc. Maybe it wouldn't work for large rooms, although I see portable oil heaters that go up to 3kW, but I don't need it for a large room.

I very quickly did a search and there were more, if this is what you are looking for

There was a helpful site and also had some model inclusions. Couldn‘t copy link, but site info is below

Thanks Maureen. I found those also, they are all only offered in the EU or Australia as far as I can tell, or can be shipped for $$$.

I came here to look for same. i have a mountain cabin and want self contained wifi enabled (wall mounted) oil radiators so i can turn them on remotely before heading out (and to have a frost proof winter protection). dont know why there isnt even ONE USA seller. they are way more efficient than standard space heaters

I was wondering the exact same thing. The oil filled radiators are so much more heat efficient. I was just searching to see if there was such a thing as oil filled in floor heating, like hydronic heating tubes but with oil. The heat level would be slower to reach, but easier and cheaper to maintain. I think the oil heat would also create more efficient radiant heating as well. It seems as if the biggest con to this system is that it takes more time to get up to temp. I don't want forced air heat and, while I love the idea of hydronic heating, the greater efficiency of oil can't be beat. And for those who aren't quite following, I'm referring to a sealed system, not an oil burning system. The oil is heated by electric elements, same as for hydronic heating, but maintains it's heat much more efficiently. If you aren't one to constantly adjust your thermostat, this would be a great system.

Oil radiant would not be as efficient as water or water glycol system. Among some of the reasons are the viscosity of oil and the cost of pumping. It doesn’t exist for a reason.

I think this discussion has gotten a bit off track, partially because of misinformation. I include my comment from last year in that category too.

Oil filled radiators are no more or less efficient than other electric resistance heaters of the same amperage. The oil inside simply provides a thermal mass of sorts to absorb the heat produced and continues to release it when the device turns itself off.

In Europe, where these devices are more common, household wiring is 220-240 volts. So, any electrical device, even one requiring a lot of power, can be simply plugged in anywhere there is an electrical socket without needing to rewire to accommodate it. If you have a room or space needing supplemental heating, if there's a socket nearby, simply hang one of these things on the wall and plug it in.

A 110v resistance "radiator" on a 15 amp circuit isn't going to do much heating, so they're not as common here.

This makes more sense. It's a shame though, because I would think that heated oil would retain it's heat longer than water does. I am still considering a wall mounted unit in my bathroom though. I've used the portable units on wheels and I love how they heat a room. Many years ago we had friends stay with us for nearly a year after their house was destroyed by a tornado. Our boys camped out in the basement and used a couple of these oil filled radiators to stay toasty. I was impressed with their performance.

Carolyn, the amount of "heat" produced by resistance is the same no matter what. I believe how much heat a liquid filled radiator-shaped device gives off is going to depend more on its wattage, shape and size than on what's inside.

If it were the case that more heat is retained longer by oil than by water, then less heat would be given off in a set amount of time if oil filled and the device would provide less warmth and would have to operate longer. I suspect that's not the case though.

@Elmer J Fudd: "A 110v resistance "radiator" on a 15 amp circuit isn't going to do much heating"

Nope. I own two Delonghi oil-filled portable heaters.

Delonghi wall-mountable heaters:

• Convection Heaters (Amazon: White, Black)
• Panel Heaters

Also:

• Ember Flex Radiant Wall Panels
• Adax Wall-Mount Heaters (ship from UK and require 240v circuit)
• Econohome panels
