Without a transformer can I make 220v space heater into 110v?

I know I have to exchange the blower motor, but what about the heating elements?

    It won't make much heat as the elements are designed for 220v. Your best bet is to get a 110v heater or wire for 220v.

    Hi, Yes, I think it could be done. It would probably much easier and safer to provide your heater a dedicated 220 volt circuit here's why, Lets say your heater draws 20 amps at 220/240 volt. If you were to simply hook this up to 120 volt it would draw 40 amps. Unless you unwired the some of the elements, well now, you have lost at least half of the rated output, you have tampered with the original wiring and that UL label is no longer valid.

    Someone else said that it would be easier to wire a 120 volt heater to 220 volt line, probably true. I have seen this done on other resistive type heater elements, but that is not what the heater is listed for. I would not do it to my own or anyone Else's. A better solution is to convert a dedicated 20 amp 120 volt circuit to a 220 volt circuit in your panel. I think you insurance company would agree.

    Sorry, but I must be blunt, for your own good. This is a terrible idea. Heaters take a large amount of power. The transformer would have to be rather large. It would cost a lot more to buy the transformer than it would to replace the heater.

    A 220 volt heater is designed for 220 volt for a reason. It cannot be safely and economically converted to 110.

    pondering the load is implementing its energy on the aspects that wont substitute something. in the experience that your equipment is a 1000W resistor powered below 240V, the present will in all danger be I=P/V , I=1000/240=4.167 A If V=110V I=1000/a hundred and ten=9.01A so that's precisely the comparable, via shown fact which you get value for the skill (wattage) you're ingesting it doesnt subject rely how plenty voltage or present day you're applying. For a subject rely of protection, it quite is bigger to have a smaller present day and a bigger voltage, to limit heating losses in cable and to break cables, via fact of this electricity is often carried on with quite severe voltage such as twenty,000Volts. once you're applying a transformer, there's a substantial possibility you would be dropping quite a few watts just to heat temperature the transformer( wattages lost interior the cables) so on the end of day you 'd greater beneficial now no longer use it. The transformation coefficient V2/V1=I1/I2=m that's superb real if the cable are superb which isn't genuinely in any respect

    I did do this by simply rewiring with a 120v cord. It can only be done if these apply to the heater--1--The blower is now running on 120v (one side) --2-- The only reason it is 240v is because it has 2 heating elements each using 120v(each one using 120v power from 240v supply) if these facts are true for your heater, you can rewire it with a 120v cord useing only 1 of the heating elements. of course this will reduce heat output by 1/2.

    Source(s): I did it and it works fine.

    by the time you change out the blower and learn to accept anemic heat from resistors designed to be fed 220, it would be cheaper and much easier to either run a 220 volt supply from the panel, or buy a 110 volt replacement space heater.

    Underwriters listed space heaters cost around 20 to 30 dollars. This is most likely your best bet, unless you have a transformer already.

    no unless ur a science geek and can rewire it...
