3 Heating system selection
Criteria for heating system selection
• Boat length
• region where used,
• Season and
• Boat form
Simplified graphical representation
1. Select the boat length.
2. Go horizontally to the left to the line for the region.
3. Go vertically downwards to the line for the season when used.
4. Go horizontally to the right.
a) Water heater: Follow the boat type line vertically downwards in the lower triangle.
b) Air heater: Follow the boat type line vertically up in the upper right triangle.
More accurate capacity rating of the heat requirement:
calculate approx. 150 to 200 W heating capacity per m³ of heated area.
For extreme cold, calculate 250-400 W per m³.
Use the upper or lower guide value according to
• Operating area,
• Boat hull/superstructure insulation,
• Integration of a hot water boiler.
Recommendations:
Air heating for ships from 15 m: use two systems (better warm air distribution and
controllability, less noise and power consumption). Use separate connections for electricity,
exhaust gas, fuel supply, etc.

4 Installation of the heating system
4.1 Choosing the location
• Install the heating system in a dry location; protected from the ingress of sea water, excessive
vibration, heat and engine exhaust gasses
• Suit the installation for the type of use/type of boat. Observe: all peripheral components such as
maximum permitted exhaust length, on-board wall duct positions, combustion air intake,
electrical wiring and cable lengths, distance from fuel tank, routing of warm air hoses, fresh air
intake, etc. For data, see the equipment-specific installation instructions.
• Observe: Maximum ship inclination cannot lead to the ingress of sea water through the
exhaust outlet.
• Inclination must not bring the heating system into contact with bilge water.
• Do not obstruct moving parts (e.g. rudder assembly)
• When arranging the heating system, avoid the danger of injury to persons or the risk of damage
to objects as much as possible.
Fire risk! The heating system can overheat.
• Pay attention to maintaining a sufficient distance and sufficient ventilation for all parts.
• Use only fire resistant materials.
• If necessary, fit a heat shield.
• Do not install in the vicinity of flammable or temperature-sensitive objects such as sails,
fenders, bulkheads, paper, gas lines, fuel containers, etc.
• When installing in a lockers or control cabinets;
• Only with good ventilation
• Prevent contact with hot parts
• If necessary, create a contact barrier around the heating system
• Recommended locations:
o not next to sleeping berths or next to the salon (because of ventilation noise)
o in lockers or control cabinets, if the are well ventilated.
If necessary create a contact barrier around the heating system so that the sail, fender,
bulkheads, etc. do not come into contact with hot parts.
o in the engine compartment of inboard diesel engines. Assuming: Hot air intake from outside,
combustion air intake from outside or the engine compartment if this is well ventilated to the
outside.

4.3 Heater mounting
• Securely mount the equipment (vibration, swell)!
• Use a mounting assembly or bracket
Air heaters: use the bracket and rubber seals provided under the feet of the equipment.
Securing Air Top®using the mounting bracket
• Recommendation: flexible mountings (decoupling oscillations, noise reduction)
• Secure the heater unit with screws to the mounting assembly.
• Recommendation, if attached to the outside skin of GRP boats: Laminate a wooden plate on
the inside at the mounting location to avoid having to drill through the outer skin.
WARNING! When drilling into the outer skin of the ship there is a risk of drowning!
Drilling under the water line can cause the ship to sink.
If the boat is in the water: check the drilling location. Keep leak sealing equipment
available and familiarize yourself with the possible escape routes.

5 Exhaust
5.1 Exhaust system
Feed the combustion gasses out of the boat through the exhaust system.
1) Heater; 2) Combustion air intake; 3) Flexible stainless steel exhaust pipe; 4) Condensation drain;
5) Exhaust gas sound absorber; 6) Isolation; 7) Goose neck; 8) On-board duct
5.2 Exhaust outlet
Outlet arrangement:
• Position the exhaust outlet where as little water spray can enter as possible.
Recommendation:
Sail boat: in the stern transom.
Motor boat: in the lateral side wall.
WARNING! Do not position the exhaust outlet underneath or next to ventilation
equipment, window openings or the heating air intake (risk of suffocation).
• at least 60 cm above the water line so that no water can enter when the boat heels.
• do not connect to the engine or generator exhaust line (higher pressure, damage to the
heater).
• not in the direction of movement of the boat (higher wind pressure).
• not where it can be covered easily, e.g. by the fender.
Wall ducts:
• Choose the design and installation position: minimize rain water ingress.
• Only metals ducts are permissible. Use insulating washers for thermal isolation from the walls.
Use properly fitting seals (minimizing water ingress).
If additional seals are needed: use heat-resistant sealant only.
• Wall ducts: Not sealable; not with self-opening valves.
