Default Hot water heater

Hi gang,

Has anyone replaced their water heater with a tankless instant recovery/ Second has anyone just replaced it with an electric heater from lowes or home depot? I really don't see much difference.

Tankless units relay on a high heat source to heat the water on demand. This is not conducive to a marine application. If in the engine compartment it must be ignition protected.

Marine hot water heaters can come with the option to be heated off of the heat exchanger as well as electric. It's also a bit more marinized and ignition protected.

If the water is hot it does not need to be heated. The device is a Water Heater, not a Hot Water Heater

Also love it when people call Fenders a Bumper.

Why would it need to be ignition protected? Electric does not ignite like gas or propane.

Electric thermostat can cause a spark which can ignite any potential gas fumes. This mainly applies to items that are installed in the engine compartment which is where my water heater is. Same is true for the engines starter and alternator, these have special features that auto ones don’t.
