Those 20 minutes let the pump keep pulling water through the heat exchanger while it cools. Without them, hot water sits still inside the heater, and the result is the pounding and knocking owners describe as the heater banging, plus scale and lime deposits that build up over seasons. Running the heater down first avoids all of that and adds service life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTiming and switching\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe clock gives up to 12 ON and OFF operations a day with a minimum one hour ON or OFF period.
