Whether you’re considering buying a new water heater or upgrading your current setup, the size and type of water heater you buy will depend on a few factors. The first factor is the number of people living in your home. You should consider buying a larger tank if you have more than two people. A smaller one would probably be fine if you have fewer than two people.
Is it Better to Have One Large Water Heater Or Two Small Ones?
Another factor determining the right water heater size for your family is the duration of your showers. If you take a long shower Underground water tanks, you’ll need a bigger tank than if you only have a short shower.
Also, if you use multiple hot water appliances at once, you may need a larger tank. A balanced system, in which all the units are piped together, evenly distributes the hot water. If you’re not sure about the best water heater for your household, talk to your local plumber. They will be able to help you decide.
The next step up for larger homes is a 70-gallon tank. This is a good size for a family of five or more. You’ll likely want to buy a 50-gallon tank if you have a smaller household. This will allow you to take shorter showers and do fewer loads of laundry.
If you’re still not sure about the size of your water heater, you can calculate the First Hour Rating (FHR). This is the total gallons of water a tank can produce within one hour.
