The Scotch marine boiler is commonly used in heating applications due to its efficient design, which allows for a large amount of water to be heated with a relatively small amount of fuel. This type of fire-tube boiler features a design where hot gases pass through tubes that are surrounded by water, which helps in effectively transferring heat. The large surface area of the tubes allows for optimal heat transfer, making the Scotch marine boiler an effective choice for heating purposes in various settings.

In addition, the Scotch marine boiler is known for its durability and capacity to handle high pressures, making it suitable for both high-demand heating applications and industrial environments. Its construction typically enables more versatility in design and installation, which is a distinct advantage over other types of boilers in specific heating scenarios.
