I believe the company is AEROTHERM based in Spearfish, South Dakota. They make a preheater which operates on a timer which can be activated by a phone call. Aerotherm. com Scott

OK, but “really cold” is relative. From here, Virginia is “really mild”. ;) That said, If you use the right oil, you do not need to preheat unless the core engine temperature drops below about 20*F. Since winter temps in VA can have some pretty big swings, I’d use a multi-weight oil, 15W-50 or 20W-50. The only way I’d recommend to keep the engine always warm is in a heated hangar (with no preheater). The problem with a preheater is that you set up a little micro climate system where the warm parts evaporate water and the cooler parts condense it. In addition, there is always the risk of fire if it is left unattended. If you must preheat, do it right before you fly. Using a timer doesn’t help much, unless you have a way to start the timer remotely before you intend to fly, although you still have the unattended issue. There is a company that makes a device to remotely activate a preheater, based on pager technology, but their name escapes me.
