I was thinking of adding a timer to my pump and heater circuit and read that some of the Intermatic timers have a feature whereby the heater shuts off 20 minutes before the pump. "Eliminates the problem of pounding and knocking due to overheated water, reduces scale and lime deposits and extends the service life of the heater."
How important is this? I have a Hayward H350 gas heater.
