On Demand Water Heaters
Using an On Demand Water Heater in conjunction with water saving plumbing fixtures
It can be a conflicting problem & solution.
Depending on the On-Demand Water Heater model, other piping, fixtures, and other miscellaneous characteristics of one’s system…..most of these water heaters require a minimum of a .5 GPM of flow (1/2 gallon of water passing through the heat exchanger) to turn on the appliance.
Sometimes water saving devices can cause problems with On Demand Water Heaters. But many of these water heaters will work if you research the specifications of minimum water flow needed to turn on the appliance.
Hope this helps!
