Hi all, I just have a quick question about the heater.

In the manuals, if I remember correctly, it said the C-Max Energi had an electric heater while the C-Max Hybrid mostly relies on the engine for heating. Can anyone elaborate more on this? 

I believe what the manual was trying to say was that both models have an electric heater but the Energi's is more powerful and can heat the entire cabin without requiring the engine.

As far as I know, there is no electric heater on the Hybrid, and I assumed that the Energi has electric heat and it has heat taken from engine heat.

 

Perhaps an energi owner can comment, but I suspect the electric heat really drains the battery quickly.

 

Of course this doesn't include electric seat heaters.

From the diagrams I've seen and previous discussion on the forum I think the Energi has electric heat, the Hybrid must rely on engine heat only.  This might be one area where the Prius has an advantage since at least the sedan has PTC heat. 

 

I guess Ford figured it was only worth doing in the Energi since it has the bigger battery pack?  Since the engine has to run to lubricate the transmission in the hybrid that they might as well use it for heat too..?

 My energi does work off electric. Works well. Gets things toasty but it sucks down the battery fast. If the reading is showing 18 miles battery power available and you turn the heat on it will drop to 13 or so. 

 

 The heated seats don't take much power. Unless it's really cold I'm good with just the electric seats.

Energi owner here. The Energi uses the same heating loop, but when in EV mode, it uses electric to heat the fluid. Once it gets to ICE mode, it uses the same loop, but heated by the engine. When in EV  mode, the temperature gauge shows the loop temperature.

 

It reduces range by about 1/4 or so, similar to the electric A/C.

It would be nice if that heater was included on the Hybrid to run during warmup and to keep the cabin warm in conjunction of the engine. Think the end result will be more efficient then just waste heat.

My 2013 Energi uses noticeably more electric power for the electric heat than for the A/C.  The impact of the electric heat is less, however, when running the ICE

 

Otherwise I agree.
