I need to get a space heater to warm up a bedroom that is on the far end of the house.
It will probably run 24/7 so energy efficiency is important.

What type is best?
Convection, radiant?
Oil filled, ceramic?
....?

24/7? That's going to run you a lot of money if you are going to be using an electric heater.

Does it have to be portable? If its going to be on that much you may just want to install a baseboard heater.

Propane has gone up so much that my bill is $300 a month and we are all propane heat. I'd like to turn down the house heat and warm up the bedroom which doesn't get a lot of heat as it is.

ALL space heaters are 100% efficient. Get an oil filled radiator type. They heat up slowly but that won't matter if it's on 24/7. A fan WILL annoy you, trust me. I have two space heaters with fans, the 2nd one being quieter, but both are annoying when I'm trying to sleep.

Some people prefer a fan when they're sleeping.

Even if you like the fan noise, the turning on and off constantly probably would get annoying

Yeah, that's what we use in our bedroom when we're sleeping. Not 24/7 though.

The fan on ours (linked above) never shuts off... or at least it never has while I've been using it.

Fixed.

Not all space heaters are electric. There are propane, natural gas, and kerosene space heaters.

OP, as you mentioned that you have propane, a propane space heater may be an option as well. Although, IIRC, they don't recommend them for sleeping areas. Last year, I installed a natural gas space heater for my tenants in the living room/dining room area. They claim it's cut their fuel bill by a huge amount because it keeps the area they're in most of the time much warmer without having to keep the entire house that warm.

Also, consider a timer for the space heater (you'll need a decent one; most of the cheap timers for lights aren't rated for as many amps as a space heater draws (again, IIRC. In the past, I had to search everywhere before I could find a timer that would handle a 1000 watt pump)

We don't run it 24/7... but it works well.
the 900W 3000BTU setting is pretty good.

At 24X7 that will be about 650kwh Not sure what power company you have. In our market that would be $71 a month to run that. And we are one of the cheapest markets in the US.

If it ran at that setting constantly, I think the room would overheat. But I don't feel like running calculations for heat loss. Presumably the thermostat would keep the heating elment on only a fraction of the time. An oil filled heater would be good because it has some thermal mass to act as a buffer between when the heater is on and when it's inactive.

All electric space heaters will suck electricity like crazy but there's not much you can do about it. I'd look for one that has a digital thermostat built in and preferably even a programmable one so you can turn it off when no one is home and such.

Good luck.

I didn't think you could use the kerosene and gas ones indoors. Also, some heaters with a digital thermostat also have a programmable clock

Yep, they can be used indoors. Regulations about them vary from state to state. Most regulations forbid their (ventless space heaters) use in rooms used for sleeping, and common sense probably says not to do so as well. However, if you really were desperate, you could probably get away with it *IF* you had a carbon monoxide and carbon dioxide detector in that room.

Check local codes always. Many prohibit unvented fuel burning appliances > 6mbh (6,000 btu/h) in sleeping areas and washrooms.

While it may be true that electric is 100% efficient that the conversion process of what goes in comes out as heat with no waste, depending on your billing rate it may not be the most economical way. Also remember that electric resistance heating dries the air and at low outdoor temperatures this becomes a problem.

Burning propane humidifies the air. If your requirements are over 6,000 btu/hr on a continuous basis an unvented propane heater may be your best bet. They have two types - radiant (orange glowing panel shaped burners) and blue flame which heat purely on convection. If the heater is running all the time convection is the most desirable. If you fire the heater only to take the chill off the air and want to feel heat immediately, radiant is better. Remember that burning propane/natural gas indoors generates CO2 and releases H20 (in the form of water vapor). It also consumes oxygen. If the oxygen falls too low the combustion process will generate carbon monoxide which you definitely do NOT want! Most certified heaters will have an O2 sensor that shut the flame safeguard valve down instantly once the ambient oxygen level falls below a preset level usually around fifteen percent. ALWAYS be sure there is adequate "make up" air available. Especially if other natural gas appliances share the same space - water heaters, dryers, etc. If you live in a "tight house" this could pose a problem.

On the sub 6k electric front, the oil filled radiator types have the lowest power density and thus are generally the safest especially if younger ones may come in contact with a portable unit.

Yup, we use that too. I do keep it on 24/7. Does a great job of keeping the room warm.

Got room for a wood burning stove?

Just a thought that probably isn't an option since I doubt you want to make a chimney.

Corn stoves are a much better solution IMO. My dad's old house was built in 1907 he had a wood stove in the basement and a corn stove upstairs. The wood was nice don't get me wrong, but when there was a wood burning ban he was still good to use the corn, the corn also self fed and it had fans on the unit to move more air.

The other advantage is now there are many corn stoves that can have the exhaust go out the wall and on the outside it looks like a dryer vent, so no need for chimney.
