Good Fan Forced Heater
 
My shed which is 10x12, with 9ft high ceiling, uninsulated but has carpeting and heavy blinds over windows, can really use a space heater. Nothing more than 1500w, although it will only be run on the low setting of 900w since I have limited power of [1] 12 gauge extension cord. I'd like to still keep my 2 shoplights and my radio :)

I had really good luck with an oil filled one on high and a box fan blowing the heat through and around, as since heat rises, it makes sense to blow the heat along the floor. This works fair, but it takes the heater about 45min to heat up, that time, and I'm usually finished with what I'm doing. That, and the fan sucks in cold air from the sides and blows that out too. This took a total of 1,000w with the fan and heater. Not so efficient for what I wanted.

I have a ceramic heater tower heater, but the fan is so weak, the hot air rises right up out of it.

I really would like a nice fan forced heater, that blows a decent burst of warm air 4-5ft across the floor, even on low. Not one of those "have to be 6in away from it to feel it heaters" It seems no one makes them. It seems like such a simple thing to be able to heat a room to an ambient temperature quickly. Im not asking to heat an un-insulated shed up from 30*F to 70*F, but at least bring it to 60*F or 65*F when its 50*F and damp outside so I can work on my projects without feeling yucky. Just about 15*F-20*F.

I would consider a quartz heater for spot warmth, but I really don't like them because of fire hazards. Ceramic heaters and oil heaters are very safe compared to most other heaters with exposed elements.

Thankyou.....

Lost your logic. If hot airs rises, why would you want it along the floor fighting the falling cool air? Why not get a small suspended shop heater (or have a machine or HVAC shop make you the fittings to suspend your own) and maybe even a ceiling fan with blades spinning the correct direction to force hot air down (people forget to turn them the right direction for the season)? I guess you could get elaborate and do a reverse attic fan thing and extract cool air out from along the floor when your system was on. If you could exhaust the cool air nature will take its course. Bath exhaust fans perhaps?

Or at least install a ceiling so all the heat stays down.

Usually for the most part, because that's where I am working. Although, I don't want to have the heater right next to me to have to feel it. I would think they would have a heater that blows hot air, similar to a window a/c, or a regular fan strength, and not just a "spit" of warm air 1 foot around the heater.

If I could get a heater that blows a decent stream of air 4-5ft, I can suspend it from the ceiling and blow it down towards the floor (like you said)

I would gladly do the ceiling fan idea, but the roof is too tight/narrow towards the top to have one, the blades would hit the wood rafters, and by time it's low enough to work, I'd be hitting my hands, head, and objects on it.

Do they sell a 900w or lower electric shop heater for $50 that can be ceiling mounted?

Would something like this work if I hang it from the ceiling blowing downwards?

Or maybe a quartz would be better for this scenario?

You have totally lost me. You want something that for the 45 minutes you are in a room takes the temp around you up so you can dance to Jimmy Buffet in a drawsting swimsuit? But you want to do this by frightening the cold air the laws of physics forces to the ground and heating things up with a plug in heater. You want to add an onboard fan to the heater. Your first thought was to do this be heating the coldest and heaviest air first, right?

What does SWMBO (She Who Must Be Obeyed) have on you bro? What on earth did you do? You are clearly not thinking clearly enough to even ask us for help.

Of course you can buy low wattage space heaters to hang from your ceiling or extend from the wall. Makes more sense than sitting one on the cold floor?

Might be time to hardwire your space if you are trying to run all on 12G extension cord though.

Ok.....let's see.....I can admit, I am confusing to understand sometimes.....it's not just you, so don't worry :laughing:

Let's put it into basics. I am looking for a heater to heat the shed. Whatever I buy, I want heat in the shed to be mostly directed at the floor or center, where I am working, but of course, can do the whole shed. This can be a ceiling heater blowing downwards at me, or a floor heater blowing towards me. The big pickle I've found with 80% of the heaters I try, is that you have to be 1ft in front of them to feel any warm air. It would be nice if they shot air like a regular fan, with a nice light heat to it. I don't want to have to sit in front of a heater to feel it. I want a mild warmth throughout.

I found that maybe a ceiling mounted infrared heater would be better, this way I feel the heat, and it warms up the surroundings. This is great since it will warm me and the things around me up instantly, and eventually over the course of an hour, if I am in there that long, the ambient temp will start to rise to a decent temp.

Just to clarify, you want this all to happen within the 45 minutes you spend at a given time in the shed or did I read that wrong?

Can I send you some mittens and a hat if we do not come up with something that works fast enough off an extension cord power supply?

LOL :laughing::laughing:

Pretty much. Maybe not heat up the whole shed in 45min, but in 1-2 hours, bring it up 15*F or so. I decided to go with a quartz heater.

Seems like the most efficient way to go with what I can do. It will keep me warm, and eventually if I am in there long enough, start bringing up the ambient temperature.
