all the space heaters i;ve seen says 1500w.
1500w /120v = 12.5amps
most home wiring = 15amps so that makes sense.
so if all space heaters use the same power, then just buy the cheapest one?

Re: If all space heaters = 1500w max, then buy the cheapest one?
From a cost of operation and max power, yes.
Otherwise, look at safety features...like tip switches (if you have a cat), or guards to protect from heating elements (if you have small kids or visitors) or noise (unless you like noise).
A lot of folks like the oil-filled radiator-looking ones because they are big and silent, and get hot, but not so hot to be an instant burn.

Some are noisy; some are quiet.
Some do a better job disbursing the heat, depending on fan, type of construction, etc.
Re: If all space heaters = 1500w max, then buy the cheapest one?
My understanding is that some use the 1500w more efficiently than others. I use the a blower/fan-like 1500w unit in our bathroom which quickly reaches high temp (and dries out the air), however in a dry basement room use a 1500w oil unit which heats more gradually and evenly since I'm down there for a longer period of time.

Re: If all space heaters = 1500w max, then buy the cheapest one?
I've never understood this "drying out the air" business. Heating air reduces its relative humidity regardless of how the heat is applied. If you have the heater blowing directly on you then that would certainly dry out your skin, but if you are just circulating the room air I doubt you would notice. If you have a real infra-red radiant heater or fire that warms you directly without heating the air in the room, then maybe there is a difference, but the oil-filled units seem to mostly heat the ceiling.Yooper wrote:My understanding is that some use the 1500w more efficiently than others.

Re: If all space heaters = 1500w max, then buy the cheapest one?
I was recently searching for one of the radiant kinds. One brand looked good until I checked the Amazon comments - there were a few hundred ratings, of which 20% were one star, with many indicating failures of the fire hazard variety. FWIW, it wasn't even the cheapest.
I lost my enthusiasm for that model.

Last time I looked (recently) electrical code only requires 20 amp wiring/circuits for bathroom and kitchen sockets. I am not sure about utility/work shop but it should be 20 amp IMO also. 15 amp is permissible in the rest of a residential dwelling.2comma wrote:Home wiring should be 15 amps for lighting circuits and 20 amps for wall sockets.Gambler wrote:all the space heaters i;ve seen says 1500w.

Re: If all space heaters = 1500w max, then buy the cheapest one?
There are features that some have and others don't. I've had very satisfactory results with a Lasko column heater. Digital temp setting, can rotate or not and power on/off and settings by remote control. I think it was about $50 at Bed, Bath and Beyond.
Re: If all space heaters = 1500w max, then buy the cheapest one?
Space heaters with thermostats are helpful.

And to make life simple and make these units useable by all they limit them to something that will run on a 15 amp circuit. They sell to people who have wiring from all sorts of time periods. I can't say that I have done a scientific survey, but general use home products seem to never be higher than 1500W.N1CKV wrote:Last time I looked (recently) electrical code only requires 20 amp wiring/circuits for bathroom and kitchen sockets.

Makes the claims of 6.5 hp shop vacs and the like a tad suspicious.
(6.5 hp = 4849W)

Re: If all space heaters = 1500w max, then buy the cheapest one?
This overview and review was helpful to me: http://thesweethome.com/reviews/best-space-heaters/
Talks about the different types and their associated pros and cons: oil heaters (usually slow to heat up initially but little to no noise and a nice "steady" heat once they're rolling), fan-based (usually heat up quickly but some noise and heat seems to dissipate quickly), etc. A lot depends on what you think your usage pattern will be and what level of noise you're willing to accept. Some of the heaters have timers. The cheapest fan heater (Lasko 754200, ~$25) is dirt cheap but a little on the noisy side from what I understand. I ended up going with a Vornado as I wanted quick heat-up time, low noise and a fan to help move the heat around and I didn't really need it to stay warm once I shut it off (like the oil heaters).
As mentioned above, Consumer Reports has a recent overview which is ok but not nearly as in-depth as the link above.

Re: If all space heaters = 1500w max, then buy the cheapest one?
It doesn't matter whether the circuit is 20A, the standard plug (NEMA 5-15) is only rated for 15A. You can plug two 10A* devices into one 20A circuit, but you shouldn't plug a 20A device into a 15A plug. And you sure as heck shouldn't design and market such a device. So a heater that uses 20A would have a 20A plug (NEMA 5-20) the one where one of the blades is at right angles to the other and does not fit into a standard outlet. Most people would not be able to use this, since 20A outlets are relatively rare.Rodc wrote:And to make life simple and make these units useable by all they limit them to something that will run on a 15 amp circuit.N1CKV wrote:Last time I looked (recently) electrical code only requires 20 amp wiring/circuits for bathroom and kitchen sockets.

Re: If all space heaters = 1500w max, then buy the cheapest one?
They all generate the same amount of heat per watt-hour consumed. Where they differ is in how, and how well, the heat is distributed. The primary methods are convection or radiation, but some convection heaters move air better than others, and some radiant heaters work better than others. I generally like the Sweethome article mentioned above, but air temperature is not exactly the right thing to measure. An advantage of radiant heating, when it's done right, is that you can feel comfortable with a lower air temperature. (If you've ever been outdoors on a cold day and noticed the sun come out, it isn't the air temperature that's changed.)
My advice is to consider your use case. In the kitchen I use a Vornado, because I turn it on when I get up in the morning and I want heat fast. In the bedroom I use a 400-watt radiant panel, because I leave it on all night and it's quiet.

Hard to believe that I can stop by Home Depot and buy a 1500W heater built for in-home use that has that level of risk. But then maybe I am wrong.

A U.L. listed heater may still be a hazard if it's abused enough, for example dropping a coat over one. This is something to consider if you have pets or small children. Some of the the more expensive models have cutoff switches that detect when they're blocked or knocked over.

From: http://www.nfpa.org/press-room/news-rel ... ting-firesWhile only 32 percent of home heating fires involve space heaters, they are involved in 79 percent of home heating fire deaths.
There are a number of safety features and measures the user can use to minimize risk.
Personally, I choose not to use the highest setting (1500 watt) at night - ever. The 600 or 900 watt setting is more than adequate in a closed room and I place it on an 18 inch porcelain tile square if the area is carpeted. You have to use the proper heater in the proper setting.

From your link:
Pretty big number. More than I would have thought.In 2007, U.S. fire departments responded to 66,400 home structure fires that involved heating equipment. These fires killed 580 people, injured another 1,850, and were responsible for $608 million in direct property damage.

Re: If all space heaters = 1500w max, then buy the cheapest one?
To further clarify this, all of your wall sockets with parallel slots are 15 AMP receptacles. You'll have 20 amp circuits in the kitchen (or bathroom) because you're likely to have multiple high current devices on one circuit. But your still only using a 15 amp receptacle and 15 amp plug and cord for each device.N1CKV wrote:Last time I looked (recently) electrical code only requires 20 amp wiring/circuits for bathroom and kitchen sockets.

A 20 Amp - 125V plug will have one blade perpendicular to the other and the 20 amp receptacle will have one slot that looks like a sideways "T" to accept either the 15 Amp or 20 Amp plug.

With regards to safety: Yes, newer space heaters available today at your local Orange or Blue Box store will be safe. Many fires start from older space heaters that do not meet anything close to modern safety standards. Avoid used space heaters at all costs.
Even newer ones can cause fires if used improperly. Because they're small, people tend to put them in strange places, and then put stuff on them, and then walk away.
