A 50 gallon water heater is perfect for a household that contains three or four people, as long as the model is gas. An electric model for a three or four family home should be around 80 gallons due to the fact that electric models tend to take longer to heat water up that gas ones. As most households are within the three or four family member range, 50 gallon models are usually very easy to find and can be relatively affordable as either gas or electric units.
It’s important to make sure you get the right sized model for how many bottles of water is a gallon your family size. For a household smaller than three people, a 30 or 40 gallon model should be large enough. Again, a family with three or four people should invest in a 50 gallon water heater. Anything larger than that should look for a water heater that is between 70 and 120 gallons, depending on whether you are looking to get an electric or gas-heated model.
All water heats are rated by the amount of water they can heat in an hour. Specifically, they are rated by how many gallons that they can heat up to 90 degrees Fahrenheit in an hour. When shopping for a 50 gallon hot water heater, this is an important statistic to look at if you do not want to run out of hot water often. Most gas-heated units can heat up more than their whole tank in an hour’s time, while an electric unit will usually only be able to heat up anywhere from 15 to 30 gallons each hour.
Paying attention to the energy efficiency of any individual heater unit is also important, as one with poor energy efficiency could cost you a big chunk of change throughout the year. You should weigh your needs when it comes to energy efficiency versus heated water recovery, as many units that can heat several gallons per hour are not very energy efficient. Figure out which feature is most important to you to get the best results out of any new water heater.
