The circulation of hot water to provide heat is known as a “Hydronic” System. It is a closed system continually circulating the same coolant. It begins with a furnace or boiler, usually fueled by diesel, or electric elements that heat the coolant to 180 degrees. A water pump circulates the hot coolant through a domestic water heater and then to the various fan units located throughout the interior of the motor home or yacht for example. An engine coolant loop can also be added to preheat the engine or use the engine's wasted heat..
| ADVANTAGES OF HURRICANE HYDRONIC HEATING |
|
| HYDRONIC HEAT FEATURES |
DISADVANTAGES OF REVERSE CYCLE AIR |
| > Constant output of designed heat > 12 volt system – no 115V required > Sealed system – no seawater > Heats domestic water on demand > Service by owner – self diagnostic > Serviceable at sea > Engine waste heat can be used > Preheat for cold starting engine. |
< As temperature outside decreases–output decreases < 115V system requires generator < Requires seawater (increased maintenance) < Cannot heat potable water < Cannot be serviced by owner – special tools & license < Not serviceable at sea < Cannot use engine waste heat < No capability |
| HYDRONIC HEAT FEATURES |
DISADVANTAGES OF DIESEL HOT AIR HEAT |
| > Comfort with warm air > Heats domestic water – unlimited > Easy installation – 3/4" tubing > Service by owner – self diagnostic > Serviceable at sea > Engine waste heat can be used > Preheat for cold starting engine > Quiet operation > Multiple heating zones |
< Very hot air, greater temperature swings < Cannot heat potable water < Difficult installation – 3" duct work (higher labor cost) < Cannot be serviced by owner – special tools & license < Not serviceable at sea < No capability < No capability < Noise level high < No ability to separate zones |
| HURRICANE HEATING SYSTEMS EXTEND YOUR SEASON AT BOTH ENDS |
