I'm not worried about body heat infact I prefer it cooler. I can't breath in cold air because of asthma. I would just need to heat one bedroom, but all the heaters are high wattage.
Wow! Propane back up in a little heater? You need some type of warm heated hood or helmet with warm air! Yikes! What is out there? You need the pedal generator' universal plug in; when a solar panel is not enough in stormy weather, if back up batteries are too low !
Quote:Chaos Thermal Regulation CTR Howler Multi Tasker Pro Windproof Balaclava Quote: We all have different tolerances for cold weather, but let me tell you how well this balaclava works for me: I've used it several times when the temperature was below 20 degrees Fahrenheit with the wind blowing at over 20 mph. Even when riding my bike at 20 mph into a strong headwind my face was perfectly warm.

Quote: One of the most effective pieces of cold-weather gear I own is the Talus Outdoor Technologies ColdAvenger Expedition Balaclava. This balaclava has a medical-grade polyurethane ventilator that covers your mouth and nose and it mixes the warm air your expel from your lungs with fresh air from the outside-the result is that you breathe in warm, moist air. This ventilator will raise the temperature of the air your breathe in from 40 to 60 degrees Fahrenheit (for example, if the air temperature is zero Fahrenheit, you should be breathing in air that is somewhere between 40 and 60 degrees). This polyurethane ventilator is both non-toxic and anti-microbial. If you head out for a bike ride in the morning in the cold and it warms up in the afternoon you can easily remove this face mask and just use the head covering.
