Winter is hard on your hot water heater. When the weather turns cold, you may want to crank up the heat in the shower or enjoy a long hot soak in the tub. If your hot water heater is not up to par, all that will be impossible.
Even worse, the hot water heater could go out completely, probably on the coldest night of the year. If you want to make sure your hot water heater makes it through the winter season unscathed, now is the time to act.
