Space heater
(OP)
Hi! I need some help about choosing the right space heater to be used inside the forcastle space of the ship. The space heater to be used just to warm up the space when the ship sail in cold place. I preffered electric type. I anyone can give me how to choose the right one like capcity in KW to be used for a given space, size of the cable and circuit breaker.
Thanks a lot ang looking forwrd for any help that you may extend.

The losses through walls, doors and windows depend also upon the difference from inside to outside temperature.
The wall thickness, material heat resistance [heat insulation], and sealing capacity of doors and windows may reduce the heat dissipation to outside.
As an example of heat loss calculation from a usual room see:
http
The power supply cable has to be calculated [or chosen] considering the required current[amperes] ,conductor material -usually copper or aluminum-the insulation material as PVC or XLPE -the heat dissipation possibility along the routing way [exposed, conduit, tray and so on].Some time also the voltage drop could be considered for a long distance.
Practically, I think you have to test the heat dissipation using a heating element suitable to the existing receptacle outlet in this room-the rated voltage and rated current- and to recalculate [proportionally] for a required difference inside -outside temperature.
In order to design the supply cables as branch circuits, installation, control and protection see NEC Article 424.
