I received a call from one of my customers yesterday, saying that his wife ran out of hot water after being in the shower for only 5 minutes. When I went there today the first thing I did was run the hot water over my thermometer to see how long the hot water would last. It was running out of a newer style Kohler lavatory faucet so I believe at full flow it was running about 2.2 gpm. (Obviously a newer shower head flows only about half of that). I had 130 degree water for a full 5 minutes then it started to drop in temperture slowly...about 3 degrees per minute. Is it normal for a 30 gallon lowboy with two 3500 watt elements(208 volts) to supply only 11 gallons of consistent 130 degree water for the first 5 minutes? I checked both elements and both thermostats....they all work fine. Doea anyone know if there's a chart from one of the manufacturers that will tell me recovery rates for different size water heaters with different elements in them? Thanks.
No announcement yet.
