If your water heater is more than 10 years old or you are noticing that your energy bills are higher than usual, it could be the right time to replace your water heater. A new water heater is more energy efficient and will improve your access to hot water. Here are the most important things to consider when shopping for a new water heater.

Hot Water Heater

Fuel Type
If you don’t need much hot water, invest in an electric water heater. These aren’t as efficient as other types, but they don’t require venting, which allows you to put an electric water heater in a wider variety of places. Natural gas, propane, and oil water heaters are more efficient than electric, but they cost more upfront and require that you install a vent.

Efficiency
When you shop for a new water heater, pay attention to the Energy Factor (EF), which measures how much hot water is produced in comparison to how much energy is required to heat the water over a 24-hour period. The most efficient score is a 1.0, which tells you that the water heater can use its energy to heat water and then transport that water to the tap without losing any heat. Most EFs are between .60 and .96, depending on the type of fuel used.

Recovery Rate
The recovery rate, expressed as First Hour Rating (FHR), tells you how many gallons of water the unit can heat in one hour. A family of two will only need a 30-gallon water heater, while a three person household will probably need a 40-gallon unit. Families of five or more will likely need an 80-gallon electric water heater or a 50-gallon gas-powered unit.
