I'm still using mine all the time, fair enough I've been able to turn the gas down so it lasts longer and is still hot. You get such an increase in speed using hot over ambient temperature that it justifies any additional cost. I wonder how many on here would shut their boilers down at home and stop using hot water to clean the dishes or take a cold bath just because we have a heat wave. Hot water cuts through dirt faster it's not just for freezing weather.
