Q: Can I convert my old space (CNE/CNA) connections to the DT series connectors?
A: Yes, each individual connector set can be replaced per Tanis instruction
TN02594
Q: Can I install this kit myself?
A: A Tanis preheat kit can be installed by an appropriately rated individual. Installation of any preheat system requires a log book entry at a minimum. An STC system should have the STC paperwork (i.e. FAA Form 337) properly filled per the aircraft's country of registration.
Q: Can I leave a Tanis preheat system plugged in all the time?
A: Yes, Tanis preheat systems can be plugged in continuously in ambient temperatures less than 100F/38C. We also recommend
SwitcheOn to remotely activate your Tanis system.
Q: Can I use a portable generator?
A: Yes, as long as it has adequate continuous wattage capacity. It could be in AC or DC even.
Q: How do I know my aircraft electrical system has enough power for a Tanis system?
A: This is not an issue because Tanis preheat system uses ground power. It is not used in flight.
Q: How long does it take to preheat?
A: Tanis preheat systems are designed so you will achieve the maximum benefit from the system within 6 hours of use. Tanis research shows a 40 to 50 degree F increase (22.2 to 22.7 C) within the first two hours of use.
Q: What kind of extension cord do I need?
A: A 16+ gauge extension cord is normally adequate for 50 foot runs. The longer the cord the heaver (lower) the gauge you should use. A cold weather cord is recommended in cold regions for flexibility and reliability.
Q: How long will it take to install a Tanis preheat kit?
A: On a general aviation aircraft once the cowling is removed, it may take two to five hours for completion per engine. Pad heat elements require curing before the aircraft can return to service. Always refer to the specific model installation manual for detailed instruction.
Q: I only want to heat the oil sump. What is the part number?
A: Tanis does not recommend or sell a single element to heat the oil sump only. Gallagher Aviation only sells complete Tanis preheat systems. Using a multi-point preheat system will "heat soak" the engine as recommended by the engine and aircraft manufacturers.
Q: My friend told me not to install a Tanis system because it causes moisture and corrosion. Is that true?
A: This is not true. Resistance heat cannot create moisture. Moisture is always present inside your engine and specifically within your oil. Use of the Tanis system will not result in corrosion because a Tanis preheat system keeps all of the metal parts that are above the oil level above dew point, and as a result condensation cannot occur on these parts. Tanis preheat systems are not to be cycled on and off as this cold cause the engine to go through dew point.
Q: What are the power requirements?
A: 115 volt (104 through 126 volt, 10%) [USA, Canada, Mexico, Japan, etc.] North American wall outlet voltage:
- Standard 4 cylinder: 240 watts/ 2.1 amps/ $0.69 per day*
- Standard 6 cylinder: 460 watts/ 4.0 amps/ $1.32 per day*
*(Average North American cost per kilo-watt in US Dollars, $0.12)
Q: When is engine preheat required?
A: For cold weather operations, engine preheat is always required. Refer to the engine manufacturer's recommendation and the POH/AFM specific to your aircraft.
Q: Where can I find more information on a system or installation documents?
A: The most current revision documentation for current systems can be found on the individual kit/system's pages on the Tanis website. General install documents include Instructions for Continued Airworthiness (ICA), Pilot guides, and common instructions can be found on the Tanis Technical Data webpage found at https://www.tanisaircraft.com/technical-data/.
