On Demand Water Heaters

[Mr. Bloom]

We have two water heaters. The original gas water heater installation. We subsequently added an electric one. The water system draws from the electric one first, which then draws from the gas one. Theoretically, we can never run out of hot water since the gas reheats much quicker. In reality, we don't ever run out of hot, but after we've gone through 100 gallons, it's comfortably warm, but not hot.

It used to be we couldn't fill our jacuzzi with hot water...now we have plenty to do that even when SilverDaughter is taking one of her typical 30 minute showers...and the high efficiency washer is running

We get through four morning showers comfortably now.

We considered an ondemand heater prior to doing this because our water heaters are at one end of the house and the pipe run upstairs and too the other end of the house (about 100+ ft)...meaning we had to run water for nearly five minutes to get hot. But, even pondering a $300 monthly water bill (mostly sewer) it wasn't cost effective for us to install on demand. They're very good for low use applications, but not for normal living...
