How Does a Marine Hot Water Heater Work?

While a marine hot water heater may look like a standard appliance you'd find in your home, it actually utilizes a unique method for heating water. The boat hot water heater includes a heating element that is immersed in the water. An AC current then powers this heating element and can be controlled through the use of a thermostat.

How Are Marine Hot Water Heaters Powered?

Typically, all marine hot water heaters are powered using one of two methods: electric or propane gas. In addition to this, a marine water heater with heat exchange can use the boat engine's wasted heat energy as an alternative power source. It's important to note that when water is heated this way, the thermostat has no real control over the temperature of the water. Instead, you'll need to install a tempering valve at the heater or an anti-scald valve at the faucet to avoid potentially dangerous scenarios.

How Many BTUs Do I Need for My Hot Water Heater?

The British thermal unit (BTU) is a measure of how much energy is needed in order to heat water. Typically, the higher the BTU, the more water a marine hot water heater is capable of heating. A boat obviously won't need as high of a BTU as a house would. So, when choosing a marine hot water tank, ensure you're getting the right BTU for your realistic hot water needs.
