What’s all the fuss about Flow Rate?

Flow Rate is the amount of water needed to activate the tankless water to heat the water and the amount of water needed to keep the machine running. Think about those times when you only need to use a little bit of hot water, shaving, washing hands, etc. Rheem is proud to have one of the lowest gallon per minute flow rate in the industry. Using only .4GPM to activate the burners and .26GPM to keep the unit running with a Rheem you can rest easy that you will have hot water whenever you need it.
