Gas Hot Water Heating
 The residential, gas-powered, conventionally vented water heater stands as the time-tested workhorse of our industry. Unlimited flows rates and large standby supplies of hot water have helped make this design the most popular style across a diverse geographic area. Whether powered by natural or propane (LP) gas, this venerable and familiar style has undergone considerable change in recent history. The most important change was the incorporation of Flammable Vapor Ignition Resistant (FVIR) technology. This new technology makes residential water heaters safer.*
In the U.S. where large, multiple and simultaneous hot water demands necessitate high flow rates, the large, stand-by hot water reserve a tank-type heater provides remains a prized attribute. The operating and energy efficiency of these water heaters continues to improve across the industry and now is approaching or surpassing the efficiencies of any other residential water heater design.
