Water Heater Temperature Rise by Inlet Temperature

Quick answer

Water Heater Temperature Rise by Inlet Temperature: 18 pages. Temperature rise is the number that decides everything about a tankless unit and much about a tank one. These pages work through every inlet temperature from 35 F to 75 F.

35 F to 105 F A 35 F inlet reaching 105 F is a 70 F temperature rise, which takes 583 BTU per gallon and sets the flow any tankless water heater
35 F to 120 F A 35 F inlet reaching 120 F is a 85 F temperature rise, which takes 708 BTU per gallon and sets the flow any tankless water heater
40 F to 105 F A 40 F inlet reaching 105 F is a 65 F temperature rise, which takes 541 BTU per gallon and sets the flow any tankless water heater
40 F to 120 F A 40 F inlet reaching 120 F is a 80 F temperature rise, which takes 666 BTU per gallon and sets the flow any tankless water heater
45 F to 105 F A 45 F inlet reaching 105 F is a 60 F temperature rise, which takes 500 BTU per gallon and sets the flow any tankless water heater
45 F to 120 F A 45 F inlet reaching 120 F is a 75 F temperature rise, which takes 625 BTU per gallon and sets the flow any tankless water heater
50 F to 105 F A 50 F inlet reaching 105 F is a 55 F temperature rise, which takes 458 BTU per gallon and sets the flow any tankless water heater
