Tips For Selecting The Right Size Hot Water Heater For Your Home

The water heater is the most essential element in your home. If you are buying a water heater for the first time or replacing an old one, figuring out the correct size will save you an unneeded extra expanse in the future.

There are some important things to consider when buying a water heater. The space where the heater goes has to fit well and have adequate ventilation. Measure the space, including the height of the room for a perfect fit. Decide on the type of heater you want electric, gas, or propane. No matter, the type, make sure it goes with your energy source. If you want gas or propane, good ventilation is important. Look for an energy saver heater it will save you money in a long run. Please remember the longer the warranty on the water heater the better the quality.

For the right size heater for your home, you need to figure out the first hour rating of the water heater (FHR). You do not want a water heater that is too big this will waste energy-heating water that winds up just sitting in the tank. In addition, you do not want to run out of hot water by purchasing a heater that is too small for your household.

To come up with the FHR numbers consider that the average person uses 12 to 24 gallons a day. Therefore, if you have five people in the home, you would take six times 12 to get an FHR of 72.

Take into account that a twenty-gallon tank is sufficient for one person, two people need a thirty for fourth gallons. Four people in the family need a forty to fifty-gallon tank, and if your family has more than five people, you will need a water heater that uses fifty to eighty gallons a day.

Another method to figuring out first hour rating is to find how much the water heater can deliver within one hour of the busiest time of your home do you use water more in morning or evening. For example, doing laundry uses twenty-five to forty gallons per load. If you have a dishwasher, you will use five to ten gallons per load. Hand washing uses three to four gallons.

Taking a hot bath uses fifteen to twenty-five gallons. A shower uses three gallons per minute. Bathing an infant uses up two gallons. Shaving takes up to three and a half gallons. Shampooing hair goes to five gallons. Washing hands uses up one to two gallons. Cleaning a home takes up to twelve gallons. Preparing food uses from three to six gallons. Adding all of these activities will give you an FHR amount. Take a week to measure your family’s use of water to get an accurate picture of how much water your water heater will use daily.
