The core of the XtremeHeater Boat Heater is a heating element that is self-regulated at a pre-set temperature and automatically varies its wattage in order to maintain that pre-set temperature. What this means is that the boat heater will increase power and heat as it gets colder to maintain the same temperature. This adaptability to outside temperatures also means less power consumed over the heating period. The XtremeHeater Boat Heater is engineered for safe operation with no sparks for marine usage. All components were selected specifically for the XtremeHeater to keep your boat safe and in optimal condition.
ALL XTREME Heater Boat Heater models utilize PTC based heaters. PTC is an acronym for “Positive Temperature Coefficient”. What this means is that the XTREME Heater Boat Heater will self limit and will also respond automatically to thermal load demands placed on it by the environment, whether it be positive demands or negative demands; this is accomplished automatically within the PTC heater by its regulation of resistance as temperatures change or fluctuate. A PTC heater will increase its resistance as temperature increases. Practically speaking, the wattage will increase as ambient temperatures fall and the wattage will decrease as ambient temperatures rise. The practical side to this is that the PTC air heater will maintain a consistent air temperature within the temperature tolerances specified and will never over heat in any circumstance.
Traditionally, temperature regulation has been accomplished using a combination of a fixed resistance heater and a thermostat. This has been, and still is today, a reliable method for heating enclosures. However, the problem can arise that if the thermostat fails you will have a heater running at maximum capacity with no way of shutting it down even as temperatures increase to an unsafe level.
The XTREME Heater Boat Heater also has a maximum output level that can adequately provide enough heating power to maintain temperatures within the enclosure at minimum ambient temperatures. But the difference is that this power level changes automatically in response to ambient or environmental demands. What happens if a thermostat fails when a PTC heater is in the system? The boat heater will shut itself down to a minimum operating level without overheating anything. It is like treading water. What happens if suddenly the fan fails and there is no airflow? The PTC heater shuts itself down to a minimum operating level without overheating anything. If there is a sudden thermal load placed on the heating system either by falling ambient temperatures or maybe a consumer caused condition, such as a door opened and cold air is allowed to enter the heating chamber, the PTC heater will automatically increase its heating power to replace the heat loss. As soon as this has been accomplished the heater will stabilize again at a lower power level, it will go back to the “treading water” mode.
So you can see a when you use a PTC based heater and a thermostat you have a control situation that can be compared to a person who wears both a belt and suspenders. It is equally as safe to eliminate the thermostat entirely and let the PTC control the temperature. The larger benefit to using the PTC technology is that risk or your exposure to liability is reduced.
Xtreme Heaters, Extreme Engine Room Marine Boat Heaters have been tested for the ignition protection requirements of the ABYC E11, the USCG,ISO 8846 and SAE J1171.
