electric blankets
I treid to post this earlier but do not think that it worked. forgive
me if it double post. Does anyone use electric blankets on board? I find that at home I only use it on the lowest settings and do not heat the rooms. How are they with battery power? I have a battery size 27, and a 1750 Watt inverter. Would I be able to use it all night? How about with shore power? Thanks |

electric blankets
A regular single bed electric blanket uses about 150 watts on high and about
50 on the lowest setting. Powered through an inverter you can expect to eat 5 to 6 amps/hour on low. . You might want to look at a 12V electric truckers blanket http://www.roadtrucker.com/12-volt-h...s-sheets-1.htm but they are only 57" x 27". Set on high 4.2 amps/hour it would eat about 32 amp hours a night. A fully charged group 27 will supply about 45 usable amp hours to 50% so you will not be able to run much of anything else. A 58'x42 will eat 9 amps and pretty well drain a group 27. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

electric blankets
This is another source for 12 volt electric blankets.
http://www.electrowarmth.com/index.htm Actually these aren't blankets but pads, they go on the mattress under the sheets instead of over you. We have a 120 volt one home and love it. -- Ken Heaton & Anne Tobin Cape Breton Island, Canada kenheaton at eastlink dot ca "Glenn Ashmore" wrote in message news:C5eGf.23339$Dh.20958@dukeread04...

electric blankets
Some manufacturers have dramatically reduced the magnetic field
intensities of their electric blankets in response to these concerns. It would be useful to do some research on the subject before making a purchase. Scientific and political opinion varies on the health risks of these fields.

So what's more efficient... using a straight 12V blanket or using a
110V one through an inverter? Seems the former would be more efficient overall, although I don't know if the difference is enough to worry about. |

The usual.
Do a search on "emf electric blanket" Chuck Courtney Thomas wrote: Don White wrote: Ken Heaton wrote: This is another source for 12 volt electric blankets. http://www.electrowarmth.com/index.htm Actually these aren't blankets but pads, they go on the mattress under the sheets instead of over you.

Thank you, Courtney Most recent warnings are about risk of fire... but I did a search using "electric blanket" + "electro-magnetic field" (probably could use EMF also) and a number of sites popped up. What's believable on the internet???? I don't know for sure but do believe in playing it safe http://www.enotalone.com/article/2708.html http://brain101.info/EMF.php |
