Engine Block Heater

Has anyone ordered one of these for their Energi? I am curious what the value is of having this on this particular vehicle? Anyone have any experience with this?

 

The value is to warm the coolant in the ICE so that in a cold environment the ICE warms up quicker.  Therefore, it should run less when the vehicle is first used on a cold day, and provide heat sooner.  It uses 0.4 to 1.0 kwh per hour, and shouldn't be run more than 3 hours (just wastes electricity). So you can take that usage and calculate your cost of using it and then determine if you think it's worth that much in gas for the benefit it may provide.  For example, IF in the morning your ICE ran for 10 minutes to warm up before shutting off, and that used 0.5 gallons of gas, and gas was $2.00 a gallon, that cost you $1.00.  If the electricity is $0.10 per kwh, and you use 3, that's $0.30.  Therefore it would be worth running.  Numbers are just made up, but you get the idea.

 

When it gets colder here (mid 20s in morning now, car is in garage that's likely mid-30s now), I will experiment with it.

I use mine all year long having an CMAX Hybrid and it increases WT about 35*F over OT, I agree leaving it on for more than 3 hours is a waist of money, it also improves MPG's on short trips too.  Maybe if it was 0*F outside when you got home you might want to leave it on all night.  For me I think it costs 4 cents an hour to run mine.  It might be interesting to run a safe electric heater inside the car when it gets really cold.

My 2013 FFE came with the block heater factory installed. If I remember right the MN, WI, MI cars all got it. Anyways I use mine in the winter it's on a timer for 2am-5:30am.

If you leave it on to long the car will kick out a false check engine code of some sort of overheat issue, I think ford has since offered a software fix to overcome this issue.

It does warm the engine up enough for me to use heat for a few minutes without the battery electric heat coming on thus saving range. Also if I jump on the interstate

2 miles from the house the engine is warmed up reducing cold shock.  I tested it with a watt meter it consumes about 350 watts.
