Re: solution for pump house heater?
Now that you have a K-A-Watt, another useful tool is an indoor/outdoor max/min thermometer . Placed at the top of the pump house room with the outdoor sensor at the floor you can see just how warm or cold it gets inside and adjust the heater accordingly. The better ones also record hi and lows , probably run about $15... or less. If you want to keep the door shut, use 2 mounted outside with the probes top and bottom, so you can monitor easily...
ps are the heaters plug-in or hard wired, ie can you use the K-A-W on them for consumption?
