Tired of being cold during a power outage and having gas furnace that won't work because it is controlled by electricity. Most furnaces are controlled by a 110v circuit. Find that curcuit and install a double pole double throw switch. One end is the house circuit and one goes to a 110v 1000 watt inverter that you can hook up to a car or marine battery. This can keep your electricity to the furnace going and keep your furnace running. Just change the switch when the power goes out and change the switch when the power comes back on.
