Here's a way to save time and energy when repairing floorboards. Instead of drilling and chiseling damaged floorboards, use a plunge router. First, use a magnetic nail finder to be sure there are no nails in the way. Set scribe lines across the damaged pieces. Then, run the router across the boards for a quick, clean cut.
Match the size of the pan to to your stovetop heating element; more heat will get to the pan and less will be lost to the surrounding air. A 6-inch pan on an 8-inch burner will waste over 40% of the energy used.
