Little heat verified by data log

More details at https://www.carscanner.info/records/

Once confirming Data Recording>Record Data is enabled, you can also just open All Sensors to record everything (and then only selecting what you want to show when it's time to chart). On another thread, someone reported that didn't work for them (nothing recorded), and it didn't work for me the first time, but it's worked flawlessly since

I heard through rumor that it helps to turn off auto made the heat work at low temperatures. Have you tried that already?

Placebo effect. But slowing the fan down manually your just making less air but it feels like warmer air but still inadequate to heat.

Ford has been in touch with me thanks to this post and forum. I hope to have a rep contact me early next week.

Nklem seems to have found otherwise (well, at least, logged a significant interior temp rise after switching from auto high to manual 3):

Interesting. Have not notice a significant change. Something is still wrong as some cars generate great heat in auto. Next cold day will try it and see.

Lucky. I have to go through arbitration which is insane for a widespread issue.

A local dealer has found a glitch, E-Heat turns itself off when you turn on the front defroster. (Max Defrost) A work around is to go in manual mode, turn on the defrost AND either the vent or floor outlet, then E-Heat remains on. In cold climate, never run the fan above 4 or 5 as then the heater is not powerful enough to heat the air.

Like it turns off in a hidden way that it looks like it's on? Or if you actually go in it looks like it turned off and you can turn it back on?

If you mean e-heat becomes “greyed out”/ unselectable, I believe that it because you’re being prevented from running max-defrost WITHOUT e-heat turned on.

I have not had that but have only used max defrost a couple times and it worked good. But was not very cold yet.

That sounds quite logical.

But if you select defrost AND vent then you could turn E-Heat off? Doesn’t make sense..

Max defrost is a dedicated feature designed to give just that max defrost you cannot mix it with anything else or its not max defrost. Ford has had this on vehicles for a while i forget the first one that had it.

Too bad they can't reprogram the HVAC to use only 50% outside air. I think right now it's either 100% or 0% depending on the recirc setting.

Lowering the blower speed will still help because then you're taking in less outside air. It's a balance between extracting enough BTUs from the heater core, and taking in too much outside air to heat effectively. It would be smart if the blower could be programmed to maintain a set vent temp of say 85ºF by adjusting airflow.

Doing some calculations, it seems the battery could be heated up about 0.5-0.75ºC per minute if all the heat goes to it, which would take about 30 minutes to warm up. Then the cabin would take another 20-30 minutes. So yeah, that's why preconditioning takes 50 minutes. I think the heater is really only sized to heat the battery or cabin, not both. They should really have two heaters or increase the output to 8+ kW instead of 5.5 kW.
