Marine water heaters heat the domestic water supply from two distinct energy sources; a traditional electric heating element, and heat transferred from waste engine heat. Engine heat is captured by running hot engine "fresh water" coolant (50% antifreeze and water) through a long tube inside the domestic water reservoir, heating (but not mixing with) the domestic water.

1) "Rear" in this case refers to the side away from you in the photo. The "Front" is the side facing you where the majority of the connections are made. "Front" and "Rear" do not refer to the orientation of the water heater as mounted in your particular boat.

3) This heater comes with a 120 volt element intended for use in the United States. If your boat is wired for 240 volts (such as in Europe or Australia) then please contact us for information on converting this heater to 240 volts.

4) Keep in mind that a previous owner may have installed additional equipment that may make it difficult to remove your old hot water heater. It is wise to remove your old heater before ordering a new one. Remember that space is tight. In may boats you must remove a teak door or drawer assembly entirely in order to provide adequate clearance for removal. Tilting and rotating the heater in varying positions will be required as you work the heater out of its usual home.
