Water coming into a 50-gallon tank at 40 degrees takes just 53 1/2 minutes to reach 120 degrees. For 60-degree water entering the tank, calculate about 40 minutes needed for the water to reach the 120-degree temperature. For 70-degree water, it would take 33 minutes.
depends on the gal size and btu of the heater. look on the panel and it will tell you the gals and btu. also is it gas or electric, single element or double. most 40 to … 50 gal heaters will recover in about 25 to 45 mins.I AM A MASTER PLUMBER LOCATED IN TEXAS. Hope this helps. The time it takes for a solar heater to heat a pool depends on the volume of the pool, the size of the solar heater, and the delivery rate of heat by the sun to the solar pane … l.

Water coming into a 50-gallon tank at 40 degrees takes just 53 1/2 minutes to reach 120 degrees. For 60-degree water entering the tank, calculate about 40 minutes needed for the water to reach the 120-degree temperature. For 70-degree water, it would take 33 minutes. A 50-gallon hot water heater with 5,500-watt elements set to 120 degrees takes about 1 hour and 20 minutes to heat water coming in to the unit at 60 degrees. Conversely, when the water entering this same tank is 40 degrees, it takes 1 hours, 47 minutes to heat it up. Water coming into a 50-gallon tank at 40 degrees takes just 53 1/2 minutes to reach 120 degrees. For 60-degree water entering the tank, calculate about 40 minutes needed for the water to reach the 120-degree temperature. For 70-degree water, it would take 33 minutes. Gas hot water heaters are more efficient than electric ones; they heat up in about half the time. The temperature of the water coming into the unit and the temperature setting to heat the water in conjunction with the power supply determine how long it takes for a 50-gallon hot water heater to heat up. Water coming into a 50-gallon tank at 40 degrees takes just 53 1/2 minutes to reach 120 degrees. For 60-degree water entering the tank, calculate about 40 minutes needed for the water to reach the 120-degree temperature. For 70-degree water, it would take 33 minutes. Speed of Recovery. The recovery time is the time the water heater takes to reheat its entire supply of water, and depends on whether the heater is a gas or electric model. A gas water heater will recover in half the time of an electric unit. A 40-gallon gas water heater can recover in about an hour. Recovery for a 40-gallon electric water heater takes about two hours. If your water heater’s recovery time leaves you too often without your hot shower, you should consider replacing your 40-gallon unit with a larger water heater such as a 50- or 80-gallon unit. Another option is the tankless water heater that heats water only as it is needed.
