I was fortunate to have a strong tailwind that assisted me in reaching the airport with a non-event landing. My mechanic said the engine failure problem was caused by lack of lubricating oil due to improper preheating. This engine had just 380 hours since overhaul. During engine rebuild my mechanic insisted that I install a preheating system and recommended the Tanis brand. I followed his recommendation and have been extremely pleased with the Tanis heater.

This failure happened to me back in the mid 1980s and I have installed Tanis heaters on each aircraft owned thereafter. I currently use the Tanis TAS 100 on my IO-360. I use this system from Fall to Spring, which is generally October to April. The Tanis heater is very economical to use, so I keep it plugged in 24/7. My electric bill cost to keep my engine properly heated in an unheated hangar is approximately just $12.60 month. I now have the piece of mind that my engine is properly heated and ready for operation.

I have over 20 years of experience with Tanis engine heaters and have had 100% reliability with your equipment. Furthermore, I have not experienced any problems associated with cold weather operation and I strongly recommend to all aircraft owners that they consider using your products.

The Tanis Preheat System is safe, reliable, easy to install and most of all, it is a preheat system that provides you with an investment that you will not regret later!

The best-known multipoint electric preheating systems come from Tanis Aircraft. We do not recommend cheaper electric systems that heat only the oil pan. As you now know, heating the cylinders and case is absolutely essential. Read the entire article at

Aviation Consumer, March 2001

As for the Tanis cylinder system, it deserves the reputation it enjoys. It’s well made, effective and remains a favored choice in cold country, where preheat from an electrically robust system is an absolute must. Mechanics we’ve spoken to speak highly of Tanis design.

I installed and operated your system on an O-470 while operating in Alaska for over 10 years. Our cutoff was -35F, your system never let us down in over 3000 flying hours and two overhauls on that engine. Thanks again for your amazing product and superior customer service.

Their customer service and engineering departments always provide us with professional attention to detail.

I have been installing Tanis products since 1999 when I got into aviation. I think they are the best system out there. Since starting my own company 4 years ago ( in Fairbanks Alaska, we have been installing their product. We recommend them exclusively to our customers. We put one of the first kits ever on the Quest Kodiak when it first came out. I will continue to promote your product in without hesitation. Thanks for a great product.

Andy Wyatt, E.T. Mechanical, LLC

Thank you for checking in on us here at E.T. Mechanical (FAA Certified Repair Station). Just to let you know, we are very familiar with the Tanis line of products and do recommend them to our customers who need pre-heating options. Unfortunately for Tanis, here in Oklahoma, we don’t experience very long periods of extreme old weather. So the requests for pre-heating options are few and far between. But for those customers who want to go at a moment’s notice even during the colder time of the year, we do recommend Tanis products. We’ve always had really good luck with them. Thanks,   (Andy Wyatt is Chief Inspector)

Everything Tanis was absolutely fabulous on my flight ( ) from Alaska to the North Pole. From the engine preheat system, to the battery preheat system, to the cowl-prop-blade covers, to the “toaster cover” for my Honda generator; I could not have been more pleased! I am very grateful. Many many thanks,
