With Reverse Cycle Heating
With reverse cycle heating in a marine A/C unit, a reversing valve reverses the flow of freon. Normally the evaporator / fan blows cold into the cabin while the condenser expels the heat into the water. When reversed, the evaporator / fan blows heat into the cabin and the condenser expels the cold into the water. Unit BTU ratings are based on it’s cool mode. The reverse cycle heat mode produces 10-15% more BTU’s than the unit does in cooling mode.
