What is the difference between a boiler and a water heater?

Boilers and water heaters are onboard appliances used to heat freshwater for showers, sinks and other domestic uses. They store and heat water so hot water is available when needed.

In marine use, the terms are often used interchangeably. Generally:

  • Boiler refers to a storage tank that heats and stores hot water.
  • Water heater is a broader term that includes boilers and other heating solutions.

On boats, most systems are storage boilers rather than instant heaters.

What sizes of boilers are available?

Boilers are available in various capacities, from compact units for small boats to larger tanks for yachts with multiple showers. The right size depends on the number of users, shower and sink usage, and available installation space

What accessories are available for boilers and water heaters?

Seashop also offers accessories such as:

  • Heating elements (replacement or upgrade)
  • Thermostats and safety valves
  • Mounting brackets and fittings

These accessories help maintain, repair or adapt your hot water system.
