Jack, I did some more reading of other people's experiences.  You should use the block heater for 3 hours, anything longer is a waste as it doesn't heat the engine any further.  You can check to confirm this with the engineering mode screen to see the coolant temperature.

Jack:

 

I assume you only use the block heater IF you plan to start the engine, otherwise its pointless right?  Electric here has gone up 37% though I don't pay for it due to solar panels if I use it then I don't get to sell it anyways so its the same thing.

Right.

 

With my previous hybrid, I would use the block heater on a timer most mornings.  It drew 400 watts.  Two hours was always enough.  20 minutes was sort of a point of diminishing returns.  Even at the outrageous price of  37 cents, I think you could heat up for 45 minutes or so and still come out ahead.  I developed a very simple test to figure out the maximum amount of gas you could save before you install a block heater (or precisely how much you save after the fact). I bet you would like it.  PM me if you are interested, and I will send it to you.

 

With the Energi I rarely do a cold start from home; so I never installed a block heater on it.  If I often did cold starts from home, I surely would install a block heater and return to using it regularly.
