Re: OK to leave electric engine pre-heater on for extended periods?
Here is an elegant pre-heat solution from the Jabiru website in the Technical Support section.
There are photos of this rig on their website.
Pre Heating in Very Cold Weather
It gets cold in Wisconsin in winter. Pre heating the engine is a must! We generally pre heat if the temp in the hangar is lower than 30 degrees F. The photos below detail a simple and inexpensive heater we built to warm up the engine while we complete our pre flight checklist and fuel up. The heater is a 1500 watt unit available in any hardware or farm store around here for about $30.00 and is commonly known as a "milkhouse heater". We added a duct adapter from Home Depot to funnel the hot air into a 3" upward flow. Then, we just set the heater under the rear lower cowl and the hot air enters where the exhaust normally exits the cowl. About 15 to 20 minutes on the coldest days produce easy starts by raising the cylinder head temps into the 80's and ol temps into the 50's.
