I have a cabin and blackouts are common, especially when I'm not there and often when it's cold. That means the pipes, even with the heating tape I have around them freeze burst and ruin the floor, since the heating tape run off the main power.
The solution of a general diesel (or similar) generator with power interruption detect switch would cost about $2,000 plus $1,000 in wiring and is not what I need.Also too expensive.
In the event of a power outage in freezing weather, I need a small space heater to heat the pipes under the house, a small insulated area. I have wired electrical outlets there.
I have identified a small 12Volt heater (designed for RVs) by Back Seat Heat Plus and another by ThermTech and these seem perfect; but I need a few other components. Both are 300 Watt, 25 amps, 12 V.
1. I need to calculate for how long a 12 volt (auto) battery would run the heater and figure out how to put 3 or 4 or whatever number of batteries in parallel to give me maybe 24 hours. Anyone agree or have another idea?
2. I need a power interruption detect switch that will turn the power to the heater on if the power goes out during the winter, ideally when it is freezing cold but I can live without the temperature sensitivity. Anyone know where I can get such a switch and how I'd put it in?
3. I need a recharging system that would automatically charge the batteries when the power is available. Anyone know what that's called, where to get one?
Thanks
