Switched Water Heaters in Series
My church recently allowed me to replace a failed 30gal. natural gas water heater with a 10gal. 110v (very easy install) electric water heater. The reasoning was that since no one was there 95% of the time, why heat a large amount of water for nothing? We're really enjoying the reduction in energy costs, but now when we have a potluck lunch ten gallons almost, but doesn't quite cut it for washing dishes, hands and babies. I'm considering installing another 10gal. 110v water heater in series ahead of the earlier one with a switch to turn on only when the added capacity is needed. The switch eliminates unnecessary energy use, and an in-series installation eliminates concerns about stagnation. Does this sound like a workable solution to our capacity problem or am I missing something?
