Abstract: A recreational vehicle water heater includes a tank for holding water to be heated and a heating element to heat the water in the tank. The tank has an inlet port and an outlet port. A cold water supply conduit is in fluid communication with the inlet port. A mixing valve has a first inlet port, a second inlet port, and an outlet port. The outlet port on the tank is in fluid communication with the first inlet port of the mixing valve. A cold water mixing conduit is in fluid communication with the second inlet port of the mixing valve. The mixing valve is configured to regulate a flow of heated water through the outlet port on the tank and a flow of cold water through the second inlet port of the mixing valve to output a flow of water at a desired temperature through the outlet port of the mixing valve.
