You installed a new 40 gallon water heater with a 54,000 BTUh burner. The underground water temperature coming into the house is 55F
How long will it take to heat the water in the tank to a normal setting of 120F.
Please show setup and explanation.
For most uses you'll want your water heated to 120 F(49 C) In this example you'd need a demand water heater that produces a temperature rise and it will take about 2 hours
