Frequently Asked Plumbing Questions
Expert answers from Jim Hunnicutt and the JLH team
Can my existing gas line support a tankless water heater?
Standard tanks use 40,000 BTUs, while high-efficiency tankless units require 160,000 to 199,000 BTUs. We calculate your gas load and upgrade your supply line from the meter if necessary for safe peak operation.
How often do tankless water heaters need maintenance in Denton?
Due to North Texas mineral hardness, we recommend an annual vinegar or citric acid descaling flush to clear scale from the dual stainless-steel heat exchangers.
How much energy will a tankless system save?
According to the U.S. Department of Energy, homes using under 41 gallons of hot water daily see 24% to 34% greater energy efficiency compared to conventional storage tank models.
