Eemax 3/4" NPT Inline Flow Regulator w/ 2.0, 3.0, 4.0, and 5.0 GPM Inserts

The most common challenge faced with a tankless water heater is when the water flow exceeds the power capacity of the heater resulting in reduced water temperature. To solve this issue, Eemax created a simple fitting that threads on the outlet side of the heater. The fitting contains an insert which limits the flow rate at a chosen level while causing almost no pressure loss below that level. With the Inline Flow Regulator installed, the Eemax heater will provide the desired output temperature regardless of the number of hot water outlets opened.
