The people at Tanis are working on a generator that you might want to research. Their primary objective is power to weight. I have thought about a Honda generator for preheating in remote areas but I would need the 2K version which is a lot heavier than the 1K. When I dream about such things, I dream of an IC engine that could replace a Janitrol heater. The exhaust heat would run through a heat exchanger to provide cabin heat and the rotary motion would power a small fan and an alternator. The alternator could be used to top off the batteries, power engine heaters, and power an electric heating element (or heat pump?) to supplement the exhaust heat. If I'm going to carry around a big combustion chamber in my nose, I'd like it to do something useful. (Heck, with my current heater, I'd be satisfied if it it simply provided heat. But when I dream...) --kyler |

Sounds like you've invented the APU. |

It's unclear to me if you're pointing out something other than what I would have thought was obvious, but if you know of an APU that can readily substitute for a Janitrol, please point it out to me. It's starting to get cold around here and my thoughts are turning toward heat... --kyler |

Sorry to hear that. I put the Reiff cylinder and hot padd heaters on my Six
back in 1996, and have had no problems with it whatsoever. At the engine change this summer, we re-adhered the pad to the new engine using some kind of hi-temp goop the A&P had on hand, and again, no problems. My guess is you may have either had some residual oil left on the sump or on the heat pad, or you had a bad batch of adhesive. My cylinder bands were custom made for me, as I bought them soon after Reiff came out with them, and the original models were too wide to fit on my narrow deck engine. I think they've since asked you to specify wide or narrow deck. The narrow deck ones are 50W instead of 60W, and are a bit skinnier. At the time, the customer service was exemplary, but since I have not had to deal with Reiff since, things may have changed. "Steven P. McNicoll" wrote: "Victor J. Osborne, Jr." wrote in message ... I've had Tanis in two planes and now have the Reiff product. The Reiff was easier to install, doesn't mess w/ the CHT probes and is owner installable w/ an A&P signoff. Everything is owner-installable with an A&P signoff. I purchased a Hot Padd heater from Reiff. The heater could not be mounted on my engine in accordance with the supplied instructions, so I made do as best I could. The adhesive didn't cure and the pad easily peeled off. I returned the pad to Reiff for a refund, they sent it back to me with more adhesive. Apparently I violated the warranty by not following the instructions to the letter, (the fact that it was impossible to follow them was of no interest to Reiff). I don't know if the Reiff heater is any good or not, I do know that their product support and customer relations are terrible. I won't do business with them again. I purchased a "milkhouse heater" and some ductwork at a local home improvement store. The cost was about $35 and it does a fine job. -- --Ray Andraka, P.E.

At the time, the customer service was exemplary, but since I have not had to deal with Reiff since, things may have changed. The heater is a flat pad. I'm sure if you have easy access to a flat oil sump, like a Lycoming, it's a simple installation. But I have an Aeronca 7AC with a Continental A65, the small Continentals have a kidney-shaped tank. The Reiff instructions stress the importance of a thin, uniform layer of adhesive between the pad and the tank. How do you keep a flat pad in contact with a round tank while the adhesive cures? You've gotta clamp it, and the instructions do say that may be necessary, as I recall. But there is no effective way of clamping it while it is hanging from the engine, so I removed the tank. While I had it off I took the opportunity to clean it up and repaint it. It was cleaned in a solvent bath, and old paint and corrosion were removed with a combination of wire brush, sandpaper, and sandblasting. I used a good quality automotive primer and paint. It was beautiful. I mixed the adhesive and applied a thin uniform coat per the instructions. I put a piece of wax paper under a large bean bag and used several strap clamps and duct tape to ensure uniform contact of the pad to the tank while the adhesive cured. I applied heat and let it sit for several days. When I removed the clamps the pad returned to it's former flat state, the adhesive was a slightly sticky gray putty. Most of the adhesive peeled off very easily, the remaining bits were cleaned off with a solvent, leaving the heater in pristine condition. The whole kit, less the adhesive, was returned to with Reiff with a letter explaining my experience and a request for a refund. Instead I got the kit back with a different type of adhesive, which I consider to be de facto admission that the original adhesive was inadequate for the task. I hardly consider that good customer relations. This was about seven years ago as well. |
