How long should a 30 gallon water heater stay hot?
Say your electric heater is 30 gallons. If the previous shower lasted 15 minutes, you’re looking at about four minutes of hot water remaining. If you want to loll in your own 15-minute shower, you’ll need to wait 47 minutes before stepping in. (Gas units heat faster, so multiply by 1.9 instead of 4.3.)
Is a 30 gallon hot water heater big enough?
A 30 gallon water heater should be able to supply enough hot water to meet the needs of a household of 1 -2 people with only one bathroom. A good way of measuring your hot water requirements is calculate your peak hot water usage and compare it the first hour rating of a water heater.
When to use a 30 gallon hot water heater?
A 30-gallon hot water heater is really only appropriate in one situation. If your home has only one or two people using hot water at the regular demand level, you can get away with using the smaller tank if it is heated with gas.

How long does it take an 80 gallon water heater to heat up?
80-gallon electric water heater: 120-130 minutes If you have a 40-gallon, 5500-watt electric water heater and set it to 120 degrees, it will take about an hour to an hour and 20 minutes to heat up. A 50-gallon electric unit will take about an hour and 45 to an hour and 50 minutes to heat up.

How long does it take a 40 gallon hot water heater to heat up?
To avoid getting into full-blown thermodynamics calculations, we can simplify and say that a 40,000 BTU system with a 40-gallon tank needs one half of one minute to heat each gallon, resulting in a half hour heat up time. If you have a smaller tank or higher BTU rating, your hot water heater’s warm-up time will be shorter.
When to use a 30 gallon hot water tank?
If your home has only one or two people using hot water at the regular demand level, you can get away with using the smaller tank if it is heated with gas. In actuality, you should only consider a 30-gallon tank if your space for the hot water heater is very limited.
