Girard's GSWH-2 Tankless RV Water Heater provides endless hot water with no wait time for showering, dishwasher, washing machine, and more. Simply turn on the hot water and cold water to the desired temperature. The onboard micro-processor monitors the incoming cold water temperature, the flow rate, and the outgoing hot water temperature to maintain a constant, steady hot water flow. The interior wall mounted digital user control panel shows the operating functions and visual diagnostics which allow for easy trouble-shooting. You can pre-set the hot water temperature from 95? F to 124? F so you don't have to worry about it getting too hot. It can be changed to Celsius instead of Fahrenheit. This 42,000 BTUs unit provides the optimum performance for RV plumbing. No special LP gas lines or special plumbing are required. It also features a quiet brush-less motor, freeze protection designed for winter use, and a compact design that fits in any tank water heater cut-out opening.
