Description:
12-Gallon Water Heater without Heat Exchanger - 240VA marine water heater is simply a small, insulated tank downstream of the pump. You must have a pressurized water system to operate a water heater. The pump draws water from the storage tank(s) and fills the water heater tank. Inside the water heater is an electrical heating element and usually a coiled tube called a heat exchanger. When AC power is available, the electrical element (controlled by a thermostat) heats the water. Away from the dock, the hot engine coolant is routed through the coiled tube to heat the water in the tank when the engine is running.Water heaters have four threaded ports. The tank inlet connects via a tee connector to the outlet hose from the pump. A check valve is required in this line or in the heater to prevent hot water from migrating back toward the pump. The outlet connection supplies heated water to the hot side of all faucets, also using tee connectors. The other two ports are for the heat exchanger connection, which varies depending on engine installation. Use only metal fittings to plumb a water heater, never plastic. If a pressure-release valve isnt integral, the heater will have a fifth port for this essential component.Raritans 1700 Series Water Heaters are built for the long haul. A glass-lined steel tank and a rust-proof jacket keep the Raritan water heater looking great and lasting for many years. Research has shown that glass-lined steel tanks are more durable than tanks made from just stainless steel. To increase longevity and fluctuations in water quality, Raritan includes a sacrificial magnesium anode that ensures a long tank life.Features:High-density non-CFC foam insulation helps the tank to maintain the hot water longer, a plus if you dont want to run the generator for hot waterThe recovery rate is 13 gallons per hourHot water at 160 degrees F when mixed with cold water can greatly extend the usable capacity of the tankBecause the heater includes an adjustable thermostat it can be set as high as 160 degrees FAll plumbing connections on one side (it retrofits without difficulty to most on-board pressure systems)Hot and cold-water fittings are standard 3/4 in. male NPT and the heat exchangers 3/4 in. female NPTSpecifications:Tank Size: 12-gallonVolts: 240Benefits:Simple installation retrofits to most on-board pressure systemsProven long-life designWithstands the rigors of the marine environmentThe glass-lined steel tank is more durable than stainless steelThe attractive polymer jacket resists corrosion from dampnessIgnition-protected, adjustable thermostatRound tanks are designed to withstand more pressure than square tanksGlass-lined steel tank for long life and high efficiencyEnvironmentally friendly CFC-free foam insulationReplaceable magnesium anode to protect the tank and neutralize acids in the waterThe tank is covered by a five-year Limited WarrantyEach unit is assembled by hand, individually tested, and backed by Raritans two-year Limited Warranty and legendary technical support team Owner's Manual (pdf)Brochure (pdf)
