A new water heater installation ensures your family has instant access to safe, comfortable water. However, it's important to choose the right size for the home. Here is a brief guide outlining how to correctly figure out the size you need. 

A Guide to Water Heater Installation Sizing

How Many Devices Rely on the System?

Before choosing a tankless water heater, determine your home's water demand level. Every household fixture utilizes a certain amount of water to operate correctly. For example, modern kitchen faucets typically have a flow rate of 1.5 to 2.0 gallons-per-minute (GPM). A shower, on the other hand, uses between 2 to 5 GPM, depending on its age.

Calculate the absolute maximum flow rate needed by the new system. To achieve this, add up the GPM of all devices served by the tankless water heater. For whole-home units, factor all fixtures and water-based appliances in the home. If you utilize multiple systems, figure up the total demand required for each section of your space.

How Many Degrees Does the Water Need to Heat Up?

The second detail you need to determine before the water heater installation is the required temperature rise. This refers to the number of degrees the water heater must warm the incoming water. For example, the groundwater in southern Georgia is typically around 67 degrees. If you prefer to set the water heater at 120 degrees, the necessary temperature rise is 53 degrees. Take this number, along with the maximum flow rate calculated above, and match it to a tank that offers qualities that are equal or higher in performance.
