Creating a comfortable microclimate in houses and apartments can now be solved relatively simply - with the help of central heating or affordable heating devices. But for a car and a yacht, more complex technical solutions are required, since the heating system here must work autonomously. Manufacturers of marine heating equipment for yachts provide the opportunity to select it for boats of various sizes, taking into account the mode and region of navigation.
If you have a small boat with a cabin, and you ride mainly in the summer and on weekends, then you don’t need a heating system at all. If you own a large yacht that is used only in the warmer months, the situation is similar. If it doesn't get too cold, you can get by with a standard air conditioner that works for heating. Owners of small enclosed trolling boats and small yachts will purchase an air heater that can warm up the premises to a comfortable level in a matter of minutes.
But on medium-sized yachts, both sailing and motor, up to 20-25 meters long, especially if the boats are intended for long voyages with long-term crew residence on board, there is no way to do without a liquid heater. Moreover, such a device solves several problems at once - from heating the ship itself to warming up the engines and heating the water in the boiler in the hot water supply system.
Below is a scale of the approximate dependence of the thermal power of the heater on the length of the vessel.
| Boat Length | Air Heaters, kW | Liquid Heaters, kW |
|---|---|---|
| 2m | 2 | - |
| 4m | 2 | - |
| 6m | 2 | - |
| 8m | 2-4 | 4-5 |
| 10m | 4 | 4-5 |
| 12m | 5.5 | 4-5 |
| 14m | 5.5-9 | 9-10 |
| 16m | 8-9 | 9-10 |
| 18m | 8-9 | 16 |
| 20m | - | 23-30 |

Types of Liquid Heaters
Type of liquid heater is defined through its working principle. General operating principle for all types of liquid heaters is as follows: a liquid (water or antifreeze) heated to 80-85 degrees is driven through a pipeline and a convector (or fan), increasing the temperature inside the cabin. Since the engine heats up during sailing, it is switched directly into the circuit using the generated heat.
For safety and control, a pressure gauge, a compensation tank (so that the pressure does not jump) and a safety valve must be installed. That is, the liquid runs along the heating circuits of the boat, approaches the engine, removes the heat generated by it and uses it to heat the cabins, then the cycle repeats.
The only difference between convectors and fans is the heating principle. The former warms faster, while the latter cools better. What to choose is up to the boat owner to decide.
Since the yacht's engine is part of the yacht's heating system, there are three types of liquid heaters designed to maintain a constant temperature inside a marine engine. Their main function is to ensure that the engine oil maintains optimal viscosity, starts smoothly and reduces the load on engine components. These heaters can operate in a variety of ways—electric, diesel, or gasoline—depending on the boat's resources and the owner's preferences.
Electric Engine Heater
Marine electric engine heaters are important components used to improve the performance and reliability of marine engines, especially in cold weather conditions. Electric heaters are connected to the engine cooling system and use 110 V or 230 V to heat the engine before starting, thereby ensuring optimal lubricating oil viscosity and reducing wear on engine components during starting. This preheating process not only extends engine life by preventing cold start damage, but also improves fuel efficiency and reduces emissions by allowing the engine to reach its optimal operating temperature faster.
Diesel Engine Heater
It works on the same principle as an electric engine heater. The difference between them is that diesel heaters use diesel fuel to generate heat and are efficient, especially when electricity is unavailable or must be conserved.
Petrol Engine Heater
The heater uses gasoline to drive it, making it convenient for gasoline-powered boats.
Why are these types of heaters so important to the safe operation of a boat? Cold water or berthing in freezing climates can expose marine engines to temperatures that can impair performance or even cause them to freeze. Cold starts can be particularly hard on engine components, accelerating wear and tear. Marine engine heaters, regardless of power source, solve these problems by maintaining the engine at a favorable operating temperature. This is critical not only for engine longevity, but also from a safety perspective, ensuring ships can maneuver as needed even in potentially hazardous conditions.
Functions and Advantages of Liquid Heaters
Heater features of any type and design are meant to ensure high-quality heating of all areas of the yacht and eliminate cold engine starts. Regular dehumidification of humid air in cabins, galleys, cabinets, engine compartments, hold, etc. - is a very effective way to combat mold. Who, if not the sailors, knows how mold can damage not only fiberglass hulls, but also wooden yachts. In addition, mold stains are difficult to remove, so regular heating of the yacht will not only protect its coatings from damage, but will also preserve their original aesthetic appearance. Experienced sailors know that good and fast heating is much more effective in combating mold than ventilation, especially if the yacht is on a long voyage in cold waters or in a region with a sharply continental climate.
The main advantage of a liquid heating system is that, in addition to efficient boat heating, that is, all interior spaces, you can heat water for household purposes (showering, cleaning, washing, etc.) and warm up the engine of your yacht before starting.
In addition, with the installation of a liquid heating system you get:
- central heating system, like in your home;
- better heat distribution using radiators;
- hot water for shower and galley;
- low noise level;
- space saving when installing in the engine compartment;
- possibility of combination with an air conditioning system;
- separate temperature settings in each cabin;
- low fuel consumption;
- combination with a motor;
- combination with a water system.
Liquid heater for yacht heating system is ideal for daily use. This one is compact design can used as an engine preheater. It meets all modern ship's requirements and standards while providing reliable protection of the housing from temperature extremes, water and sea salt.
With the help of heat exchangers (fan coils), it is possible to blow the windshields of the pilothouse and equip the exits to the deck of the yacht with a thermal curtain. Many marine heaters are equipped with special non-flooded “on-board” gas exhaust systems , which make it possible to install the device below the waterline.
Modern liquid heaters are integrated into high-tech complex climate systems that work for both heating and air conditioning together with air conditioners.
The main thing is to choose a liquid heater so that it fully matches the characteristics of the yacht, then the owner and crew will be able to make the most of all marine heating benefits.
Please note that most of the liquid heaters presented on the marketplace are designed for both boats and cars, and almost each of the models is presented for two types of fuel systems: gasoline - 12 V and diesel - 12 or 24 V.
Also available are universal hydronic heaters, also known as water heaters, that operate independently of the engine. Models such as AUTOTERM Flow 14D come with a complete installation kit and are often used as a heater for small radiator systems or boilers with a maximum capacity of 70 liters.
