Merge with fan heater?[edit]

I think the fan heater article should be merged into this one, seeing how they are basically the same thing (the fan heater being a type of space heater). 77.180.83.245 (talk) 21:01, 15 October 2011 (UTC)

I agree that the fan heater article should be merged into the general space heater article. I don't think there are enough unique things about forced-convection space heaters to have a seperate article. I don't want to do the work, though. I did add a link on the space heater page under convective heaters to the fan heater article, so at least people can find the other page. Bosef1 (talk) 14:35, 29 October 2011 (UTC)

A little more explanation?[edit]

What a tidy article!

Small comments: The reference to "hydronic heating" is too elliptical...I'm not quite sure what that means, though I can guess. Also, "ceramic heating elements" is two links to "ceramic" and "heating elements", neither of which explains what that item is compared to "nichrome wire".

It's not correct to say that "modern" heaters don't use nichrome...I live in a high tech area, and there are plenty of new nichrome heaters in the store's product lines. (And is ceramic better somehow? Am I missing something?) Alpha Ralpha Boulevard 00:32, 16 November 2007 (UTC)

can the ceramic inside Ceramic space heaters break and get brown into the air? —Preceding unsigned comment added by 74.65.3.30 (talk) 07:13, 24 February 2009 (UTC)

Ceramic Yes, more information on advantages and disadvantages of ceramic. What are pros and cons of ceramic. How does ceramic enable use of plastic cases? There are plenty of plastic encased, portable, electric space heaters available in retail stores having the same wattage as ceramic versions.

Incandescent Lignt bulbs It is no longer believed that normal use cycling incandescent lights on/off has a significant reduction of their life. Even if this were so the cost of keeping the bulb on would be more than replacing bulbs. Also the duty cycle would be an important consideration. How do we know when the number of cycles shortens the life of a bulb more than the accumulated time of normal use on only when needed? And is there enough variation between bulbs and element technology that it would be different for each type.

What is the heat produced by different types of incandescent bulbs. They are convenient for heating small areas. As for insulation. A well insulated house can be good or bad depending on the climate. —Preceding unsigned comment added by 207.5.231.198 (talk) 15:58, 6 November 2009 (UTC)

Implement info from air heater[edit]

This info needs to be imbedded:

An air heater or space heater is any appliance that warms a small area, such as one room. [1]

Air heaters include:

major edits[edit]

I have just done an overhaul of this page, including moving it to a new title. There were entire sections that dealt with central and even district heating systems as opposed to space heaters, passages clearly slanted against certain types of heaters, and some awkward writing that needed cleaning up. I also removed the section on "micathermic" heaters. It was sourced only to a website selling the heaters, and in my opinion did not explain at all how such a device works. It said mica was used as a heat source, but failed to explain how. I would imagine the idea is similar to ceramic heating elements, but I don't know that for sure and apparently neither did the person who added the section in the first place. There was also a lot of content "bashing" oil and gas burning stoves, I have tried to remove or rewrite that content in order to maintain neutrality. The fact of the matter is that where I live vented kerosene space heaters, locally referred to as "oil stoves" are used by the majority of residences, and are operated safely every day by thousands of people.

Halogen space heaters[edit]

I recently bought one of these. The bulbs were so bright that I couldn't look at them. This was just as well because it said in the instructions "Do not look at the bulbs, it might damage your eyes". The whole point of a radiant heater is that you sit in front of it, and you can't sit in front of it without looking at it. I therefore wonder what these heaters are for. I took it back to the shop and exchanged it for a convector heater. Biscuittin (talk) 21:29, 23 February 2010 (UTC)

Efficiency of halogen space heaters[edit]

I think 85% efficiency is poor. An electric heater should convert 100% of the electrical energy into heat. What else would it convert it into? Biscuittin (talk) 12:38, 11 March 2010 (UTC)

There is no method of generating heat that is 100% efficient. All electric heaters waste some electricity, all gas or oil based heaters waste some fuel. Most electrical heaters work on electrical resistance principles, like a toaster. By the way, the purpose of this page is to discuss how to improve this article, not a forum about space heaters. Beeblebrox (talk) 17:22, 11 March 2010 (UTC)
I read Biscuittin's comment as questioning the statement, "They are light weight, efficient converting about 85% of the input power to the output source of energy." If it were not so poorly worded, one might not question its accuracy so quickly! Anyway, Biscuittin's comment seems perfectly appropriate for this page. Taquito1 (talk) 02:32, 12 March 2010 (UTC)
All of the expended energy must go somewhere: visible light, infrared, sound, chemical conversion. Where is it that the other 15% goes? Also, in typical situations using a heater, much of the non-infrared would be converted to heat of some kind. Not much of the visible light in my place escapes to the outside at night with the curtains closed. Alpha Ralpha Boulevard (talk) 13:22, 15 March 2010 (UTC)
It's not about where it goes after the conversion from electricity to heat, it's the loss that occurs during that process. Without the engineer's plans for the heater (and smeone who knows more about electrical engineering than I) that about as specific an answer as you're going to get. It's possible there would be someone at the WP:REFDESK who would know more though. Beeblebrox (talk) 16:50, 15 March 2010 (UTC)
Er, I was being too tentative about my level of expertise. There is nowhere for electricity in an electric heater to go, except the places I mentioned. My guess is 99.9% is heat (infrared radiation) or visible light (other radiation). When an electronic device, such as a motor is inefficient, typically that inefficiency is lost in heat (rather than, say, in motor power). In the case of a heater, that "loss" wouldn't make a difference, since the goal is to make heat, anyhow.
(As a side issue, this is one of the problems with advocating replacing lightbulbs with "more efficient" -- and more expensive -- ones. In my home 100% of the heat is electric, so in winter, it makes no difference how "inefficient" the lightbulbs are, I have to heat the place one way or the other.) Regards, Alpha Ralpha Boulevard (talk) 20:21, 15 March 2010 (UTC)
Absolutely with you on this. It makes little sense to speak of the "efficiency" of a heater. Heat is practically the definition of inefficiency. Notwithstanding this, I think this particular statistic refers to the proportion of energy that is released as radiant heat in the IR band rather than as convected or conducted heat in the air.

Safety and Specs[edit]

I've added some links to UL and GSA safety standards in the Safety issues section, as well as some links to US DoE and EPA safety and efficency. This is obviously United States-centric, so please add addtional links for other countries as necessary. Bosef1 (talk) 14:15, 29 October 2011 (UTC)


I heard a rumour that there is a safety feature in that the glass can shatter (explode). Does anyone have any information on this? — Preceding unsigned comment added by 123.243.173.222 (talk) 17:15, 14 April 2012 (UTC)
