What You'll Learn
Diesel air heaters
Keeping a boat warm, especially during colder months, is essential for comfort and safety. Diesel heaters, both air and liquid types, offer efficient and reliable solutions for marine environments.
Diesel liquid heaters provide versatile and quiet operation with even heat distribution. Warm air blower heater matrixes increase the efficiency and reach of liquid heating systems. Calorifiers provide the added advantage of domestic hot water production.
By understanding the workings, components, and advantages of these systems, boat owners can make informed decisions. This knowledge helps them choose what best meets their needs and conditions. Whether you prioritise rapid heating, quiet operation, or the multifunctional benefits of liquid heating, a diesel heater system will provide warmth.

Diesel liquid heaters
Keeping a boat warm, especially during colder months, is essential for comfort and safety. Diesel heaters, both air and liquid types, offer efficient and reliable solutions for marine environments.
Diesel heaters work by atomising a mist of diesel in a chamber and igniting it with a heat exchanger jacket to transfer the heat. They are very reliable, do not require intensive servicing and operate under lower power levels. However, they are very expensive to buy.
The internal workings of an air heating unit (or blown-air unit) are similar to those of a diesel liquid heater. They are compact devices containing an internal burner with an electric fan that blows warmed air into cabins via concealed ducting and outlet vents. These units draw small amounts of diesel from the boat’s main tank and are suitable for boats from 15ft to 35ft. They provide rapid heat, with minimal start-up time at relatively low cost.

Warm air blower heater matrixes
Keeping a boat warm is essential for comfort and safety, especially during the colder months. Diesel heaters are a popular choice for boat heating, offering both air and liquid heating options.
Diesel air heaters are compact units that burn diesel fuel to produce heat. This heat is then distributed through the boat's interior via a fan and duct system. These heaters offer quick and direct heating and are suitable for boats ranging from 15 to 35 feet in length. They are also relatively low cost and do not require intensive servicing.
Water-based heaters, also known as diesel liquid heaters, are larger plumbed-in units. They use an internal burner to heat water, which is then pumped around the boat in pipes similar to a domestic central heating system. These heaters provide even heat distribution and quiet operation.
When choosing a heating system for a boat, it is important to consider factors such as rapid heating, quiet operation, and the multifunctional benefits of liquid heating. By understanding the workings and advantages of different systems, boat owners can make informed decisions that best meet their needs and conditions.

Calorifiers
Boat heaters work by burning diesel fuel to produce heat, which is then distributed through the boat's interior via a fan and duct system. This is the case for both air and liquid heaters, although the latter offers more versatility and quiet operation with even heat distribution.
Liquid heaters use a warm air blower heater matrix to increase efficiency and reach. They also have the added advantage of providing domestic hot water via calorifiers.
The size and capacity of a calorifier will depend on the size of the boat and the number of people on board. Larger boats with more people will require a bigger calorifier to meet the demand for hot water.
Like other boat heaters, calorifiers draw a small amount of diesel from the boat's main tank. This fuel is used to heat the water, which is then circulated around the boat. Calorifiers are designed to be efficient and reliable, providing a consistent supply of hot water for the comfort and convenience of those on board.

Water-based heaters
The water supply branches off the run to the cold taps and goes via the heater to all the hot taps or mixers on the boat. The unit is gas-fired and has a pilot light which is lit with a push-and-hold electric ignitor. Most people only light the pilot light when they need hot water as it only takes a second to do so.

Frequently asked questions
Boat heaters work by burning diesel fuel to produce heat, which is then distributed through the boat's interior via a fan and duct system.
There are two main types of boat heater: air heaters and liquid heaters. Air heaters are compact units that burn diesel to produce warm air, which is then blown into cabins via concealed ducting and outlet vents. Liquid heaters use an internal burner to heat up water, which is then pumped around the boat in pipes.
Boat heaters offer quick and direct heating, with minimal start-up time and relatively low costs. They are also very reliable and do not require intensive servicing.
