A heater is important for comfort and warmth.

At home, I have a ducted heating system and in the car, I have a dual climate control heater. Now I need that cosy feeling on my boat. On the queen side bed at the stern, I use a dual control electric blanket for a good night sleep. 

On board, I have also added fridge, microwave, TV and an entertainment sound system.

However, when it's freezing outside, I need warmth for cooking, eating, dancing, watching TV, etc.

It's ok if I'm at a caravan park. I can plug an electric heater but 240V power is not available freely on land and water.

The challenge is for me to install a heating system that is safe, secure, reliable, effective and easily maintainable as well as environmentally friendly.

My new toy is a 12V diesel heater.

 

Diesel offers many benefits over regular heaters.

Safety & Regulations

Diesel heaters are widely used and considered to be very safe. But their uses are mainly in caravans and land vehicles. I have a yacht that I trail on land as well as sailing on water. The difference is where to mount the heater unit, the intake and exhaust of the diesel fuel.

Unlike a land vehicle, it’s easy to let the exhaust fume under the vehicle just like the engine exhaust is located under the body. I can’t do that on my yacht.

In my yacht the challenge of installing a diesel heater is that everything must be mounted well above the hull, close to the deck. Sound simple but these openings must be free from water entering the heating system.

Although a land vehicle can be subject to vibrations and rough terrain, hitting waves and healing the yacht are factors that I must consider of where to install the heating system.

Diesels heaters have a reputation of being very safe. They include an auto-shutdown if the system temperature exceeds a safe operating level, the same as LPG heaters. Where diesel heaters provide extra safety is in regards to combustion and inhalation. If there is a leaking LPG fuel line, not only can it cause an explosion, it can also cause permanent nervous system and respiratory damage or in the most extreme case, death.

A diesel heater does not have these hazards. It is difficult to ignite.

Greater Temperature Control

LPG heaters only have a single speed fan. This is turned on and off as needed by the thermostat. Due to this, it’s difficult for LPG heaters to maintain constant room temperature. But, the diesel heaters have advanced microprocessors, which allow them to control airflow and combustion. This provides a variable fan speed and lets them keep a constant and comfortable temperature.

A diesel heater is cheaper to run than an LPG Gas heater.

How Diesel Heaters Work

A diesel heater directs the cold air by using an intake duct. It then passes over a cylindrical metal surface which is hot. This heats the air which passes through it.

The ducting then directs fan-assisted air straight to an outlet. Warm air is pushed out of the duct and enters into the room.
