Time to Say Goodbye to Your Water Heater? Some Factors to Consider Before You Purchase a New One

Having to replace a water heater isn’t something you’ll have to do often, but when you do, you’ll want to be backed up by some information. Next to your cooling and heating systems, water heaters use the most energy in the average home. This guide can help you navigate your way through the process. 

Type

Your two main choices when replacing your water-heating system is a traditional storage tank system or a tankless (or demand) water heater. The most common choice consumers make is a storage tank system because of the ease of instaGeisel 9.10.13llation and initial cost. A tankless system, which heats water on demand with an electric or gas-powered heating element, has a higher initial cost. However, it typically will last twice as long and lower water heating costs by as much as 60 percent, compared to a storage tank system.

Homeowners with smaller households or homes may benefit from a tankless systems, while a larger family size or one whose bathrooms are far from the main tankless heater may need two to keep up with demand.

Sizing

Choosing the size of a storage tank water heater involves calculating the amount of hot water you need during the hour when you use the most. Water heaters carry first hour ratings (FHRs) that indicate the amount of water a unit can heat in one hour’s time. The Energy Guide label found on water heaters shows this capacity. Going by the size of your existing tank could be misleading and contribute to higher standby energy losses (the amount of energy wasted in a storage tank water heater when the hot water’s not being used). This is especially the case if your existing tank is oversized for your home.

Sizing a tankless system is similar to a storage tank heater, though you’ll have to consider both the flow rate and temperature rise you need at one time when using hot water. Underestimating either could result in a water heater that won’t have sufficient capacity for simultaneous uses.

Energy Factor

The energy factor (EF) indicates how well water heaters utilize energy to heat the water. This rating is also found on the EnergyGuide label. Higher ratings indicate better efficiency.
