It takes almost 10 minutes for this large 1500 watt kettle to boil. Radiant heat is comfortable, and doesn't fly away to the ceiling and then upstairs right away. There are times, when I want to use the phone in the kitchen, but I don't want to heat the whole place. I use this kettle. After it's heated, it goes under my chair, then a sheet or blanket is draped over me and the back of the chair. The heat is trapped in an area of approximately 8 cubic feet. I usually drape another blanket over the front , after I'm seated. You would really have to try to spill the water, when it's tucked under the chair. I've also use a micro furnace in the same way. It has a thermostat that prevents overheating.
The same can be done, if you're sleeping in a big easy chair that has the footrest that kicks out. Put the kettle or heater right under the foot rest. Be sure that the blanket draped over, has plenty of length, so that your heat doesn't escape.
An electric blanket, would negate the need for any of this, and I really should get one. I don't buy into any of the EMF stuff, so I'm the perfect candidate.
Sometimes, when staying in houses I'm working on, where the heating system is shut down, but there is still electricity, I move into the smallest room I can squeeze into. Often that's the walk-in closet. I use two of these kettles. Moisture isn't an issue, since they stop, the moment they boil. I usually turn them on half an hour before bed. Now I can get undressed and get into bed, in an otherwise frozen house, in relative comfort. If I stir in the night, the buttons can be pushed again. I usually activate them, early in the morning, and then take a few minutes waking up and getting dressed. The kettles are taken to the bathroom, for face and hand washing.
I've been looking at electric blankets. There are some that plug into regular household power, and others that are 12 volt. Both use a miniscule amount of power. For me, once the bed is warm, I'm good for the night. All night warmth, for a penny.
Milwaukee and other cordless tool makers, sell 12 volt jackets. That would be awesome when I go to jobs where car camping is necessary. There is a hand warming feature. Great for hands, snacks and keeping electrical tape warm.
The last photo shows me camping in snowy conditions, with no heat at all. Got so hot that I had to remove some blankets.
