A major problem for me is my pool pump network of pipes. My pool must run year round for 12 hours a day. At temperatures below freezing the pump turns on continuously to prevent freezing. We lose power a lot and my generator only powers the 120Volt circuits. I keep a 60 Watt incandescent bulb inside the exposed pipes and filter box. It turns on automatically when utility power is lost. That 60 watt bulb is enough heat to keep my pump, heat pump, and pipes from freezing up solid and breaking. Space heaters draw too much current and are a fire hazard unattended. I need that heat from the incandescent bulb!
100 watt incandescent bulb is also great in the chicken coop to keep the hen’s warm and laying throughout the winter.
The ban on incandescent does not apply to incandescent heat bulbs...you can buy all of those you want. I have a small portable "greenhouse" that we put potted plants in when the weather will be freezing. A thermal switch that turns "on" when the temp. reaches 40F and "off" when the temp rises above that and two heat lamps...
