Electric Blanket ?

so the blankets of today are safety type blankets.

This might be in relation to some types of "throws" and heating pads automatically turning off after 3 hours. I have a couple of them and it drives me nuts when they do that. And I would not be surprised if our ever helpful government also regulates the maximum temp, too, these days.

I have a large heating pad. You have to keep the large switch depressed, otherwise it cuts off. It's for sure you won't go to sleep and leave it on.

I used the 12v electrowarmth when I used to drive semi. Worked very well.We have a 120v mattress pad on our bed in the Voltage, OEM. I cannot use it, as even at the lowest setting, it is too warm for me.

Wife unit different! LOL

We have Biddeford in the RV and the house. They're the best we've ever had. Craig

Modified Sine Wave inverters and standard grade generators (also MSW) are the problem with the electronic controllers. As long as a Pure Sine Wave inverter or inverter generator are used they work fine.

All ElectroWarmth heated mattress pads are 115 volts AC except the 36"x60" bunk warmers which are 12 volt DC.

I saw that they had an RV queen size, and "assumed". Cocky me missed that little detail. :o

I have the 36" wide mattress heating pad, and love it.

Crank it up to max 2 hours before climbing into a 114f degree bed, then turn it down to the very minimum, which on my controller is below the "1".

If I fall asleep without lowering the dial I wake up a few hours later extremely overheated. The whole mattress seems to be 120f and I cannot find any happy medium for a while as removing the covers is too cold and removing just a few leaves hot and cold spots, and I got to roll around like a hot dog for an hour till the mattress itself cools down. I have busted out the fan in desperation once.

While the provided ciggy plug itself is of a good design, and fits nice and tight in the receptacle, there is a lot of voltage drop, around 2 volts worth. My ciggy plug receptacle is wired over about 7 feet of 10 awg.

The mattress pad consumes only about 4.0 amps when it is seeing 10 volts but will consume about 6.2 amps at 12.8v.

Do note this mattress pad is not instant heat, like how I remember 120vAC heating blankets. It takes a while before it really is noticeable. Also the controller itself and where it is located will effect how often it cycles. Keeping it under the warm covers will limit heating, keep well away from heat.

Once I remove the Ciggy plug from the equation, using a 45amp powerpole connector, I bet this will improve heating performance, but really, it is more than adequate even with the significant voltage drop, but I am wasting energy by heating the ciggy plug and receptacle.

Since my Ciggy receptacle is likely wired much thicker and much shorter than most wired by any factory, inadequate performance by excessive voltage drop is a likelyhood.

On a somewhat related note I have both a modern 120v heating pad that has the infuriating timer which shuts off after 45 minutes or so. I am tempted to figure out how to disable this nanny state feature. I recently dug out an early 90's heating pad just because I know it did not have this problem. I use it as a heater for my Sun shower when I have grid power as it takes a good 12 hours to bring 55 degree water to above 100f. Great for a post surf hot rinse and I use my PSW inverter to keep it going nice and hot while driving to the ocean and during my salt water therapy session.

IF you plan on using the mattress pad in the RV on an inverter, make sure you get the one with analog controls from Target. Most of the ones with electronic controls do not like the typical RV inverter.

Thanks for the replys folks.
I guess I must have just got a bad electric blanket, cause it sure heat hardly any at all at any setting.
The light on the thermostat control as a night light, is all its good for at this point.

Those mattress pads heaters are interesting, I guess I should check into one of those, cause I'm mostly after warming the bed before I get in.
Thanks, Neil

Has anyone seen a 12 volt matress pad?

The ElectroWarmth bunk warmers are 12 volt, but only 36"x60". I use two crossways top and bottom on a short queen. ElectroWarmth used to make a 12 volt queen mattress pad but discontinued them some years ago. Maybe if enough people let them know they would buy one they could make them again.
