Getting into a cold bed
at night can be discomforting, so why put up with it?
On our V-berth, a double blanket is out of the question, so we got our old queen where one side only worked, and cut out the inoperative side.
We sewed on some tapes to tie around the mattress and what we have in effect is a single
blanket -- for my wife's side because she feels the cold shock more.
In any case, my bare feet touch her heated side and that's good enough for me.
blankets won't suit because at the narrow end they would have to go one on top of the other, which may produce safety
To power it, we use the house 1500 amp modified sine wave inverter
. Blankets with electronic controls with fancy LED displays will probably NOT work
with a MSW in our experience.
But a simple old fashioned on/off 1-2-3 mechanical controller should. It's not the heating
elements which are the problem --but the controllers.
So, about 20 to 30 minutes before bedtime, I power up the inverter
, and switch on the blanket. By bedtime it's warm, and we switch off it first then the inverter.
The blanket is about 60 watts, so it draws about 5 amps (the equivalent of
2 1/2 12-volt cabin
lights before led came along). But since it's not on for the full hour, the total draw is a very manageable 1.6 - 2.5 amps. That's about 1 hour's worth of TV viewing for the battery
How do we keep warm until bedtime in winter? -- our 2 kw planar diesel
. Love it, but that's another thread:
