how to reduce the amount of water wasted from a tankless heater?
We have a new tankless water heater serving two bathrooms. The shortest run is about 14 ft. to the nearest shower and about 25 ft. to the further one. We live in the San Diego area, and are in major drought. We save gas, yes, but we waste gallons of water waiting for the water heated at the heater to reach us. The only circulating pump authorized by the manufacturer only works when the water is running, so I can’t see how that saves water. We are considering point of service heaters for the sink faucets (we never run them long enough to get hot water in at all) but what can we do about the showers? Five gallon buckets are a last resort!
