Raritan 20-Gallon Water Heater w/Heat Exchanger - 240V 172012

20-Gallon Water Heater with Heat Exchanger - 240V

A 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 isn’t integral, the heater will have a fifth port for this essential component.

Raritan’s 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:

• A heat exchanger (the heat exchanger allows the user to heat water when underway by circulating engine cooling fluid through the almost 7-foot-long coil within the tank)
• The recovery rate can be as high as 18 gallons per hour
• High-density non-CFC foam insulation helps the tank to maintain the hot water longer, a plus if you don’t want to run the generator for hot water
• Hot water at 160 degrees F when mixed with cold water can greatly extend the usable capacity of the tank
• Because the heater includes an adjustable thermostat it can be set as high as 160 degrees F 
• All plumbing connections on one side (it retrofits without difficulty to most onboard pressure systems)
• Hot and cold-water fittings are standard 3/4 in. male NPT and the heat exchanger’s 3/4 in. female NPT

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
