I notice a lot of people prefer to have bypass valves plumbed with their heaters so they can bypass the heater when not in use because, they say, it prolongs the life of the heat exchanger and because the pump uses less energy to move the same amount of water without the heater being in the line.
I, too, plumbed a bypass valve when I installed my natural gas heater recently. One thing I have been curious about is what people with more experience say about the stagnant water inside the heater when it is bypassed? Are you supposed to drain the heater every time you bypass it? Is it detrimental for the heater if the stagnant water stays in the heater for an extended period of time when it is bypassed, say, in the summer? Assume water is balanced (pH 7.4-7.6, Alkalinity 100ppm, CH 300ppm).
