My Power Stroke is cold blooded. It takes 5 or so minutes of driving before I get any meaningful heat at +20F, even with a 5 to 10 minute warm up idle.
At -10F it takes 10+ minutes of driving.
I've been seriously looking at purchasing a winter grill cover.

Yeah rapid heat is nicer when its in the teens. When its in the teens it does heat the inside faster.
As far as the block heater, It not just easy start up, its easier on the engine because the metals and have contracted because of the cold. It heats the block, oil, and coolant which is a good thing when it is cold. I don't think the coolant is any where near a 100 degrees. I will get a block temp and post it when I can back home.

Once my coolant hits about 100-110 I can start feeling warmish air. If I plugged the engine block heater up I start off pretty dang close to that. In the mornings it takes me less than 5 minutes to get to work and the heat will easily be warm by then and the cab will be comfortable. And I do not have the rapid heat. I thought I might wish I had it, but so far I haven’t. I could see it being more helpful in super cold temps and heavily frosty/icy windshields though.

All Canadian trucks have the supplimental heat so I can't compare to anything other than my older trucks that don't have it and it does warm up much faster. I also plug in at any temps below zero so I'm not sure how long the rapid heat system is actually running.
I have remote start and whether I use the fob or the ap, my heated seats are activated and work great.

As far as I can tell, Ford doesn't sell a winter cover. Maybe I can pop the top plastic piece off the core support and slip a piece of cardboard down there (behind the grille and in front of the cooler stack).

So, I did a test this morning. I left the truck outside all night. Temp at 5:30 am was 19ºF, frozen fog on the windshield and side windows. I did not plug in the block heater. Remote started the truck and let it run. At 2 min in, I started to see the windshield start to defrost, at 5 min the windshield was defrosted ¾ of the way up, and at 9 min, the windshield and side windows were almost fully defrosted. No question that the Supplemental Cab heater is better than what I experienced with my 2008 F250 6.4 PSD w/out a Supp Cab Heater. I would get very little defrosting until after driving for 20 min w/out using the block heater. I feel the Supp Cab Heater does make a difference.
Now the bad news. Heated driver's seat was cold after 13 min after remote starting. I felt no warmth at all with my hand. Ironically, I had a service appointment Tuesday to have the deep sleep issue resolved (SSM 51140), and asked the Ford Tech to check out the remote start driver's heated seat functionality b/c when I would remote start I didn't feel any seat heat and the 3 red lights would not turn on until I jumped into the truck and pressed the start button, then the 3 led lights would light up. He told me that he checked OASIS and found no codes and he also check out another truck in the service bay and it acted the same way as mine did. The heated seats work and in fact get too warm after driving for 10-15 min so I normally turn them off at that point or set to the lowest setting. However, this remote start just makes no sense to me, and I would have thought that the driver's seat would start to heat once the remote start was activated. IDK, just seems crazy to me if this is how Ford designed the system, and if so, why have the instrument cluster remote start menu settings for heated seat and steering wheel for "auto" or "last setting".
In those menu settings, there is also a check box for "System" which if checked it allows you to change the heated seat and steering wheel setting mentioned above. If you uncheck the "System" it grays out the heated seat and steering wheel and you can't change anything. To me that means you would uncheck if you did NOT want heated seats and steering wheel to turn on while remote starting.
Anyway, just wanted to pass along what I am experiencing.

Same for my on my heated seats. I can remote start and when I enter the truck neither the steering wheel or the seat have any perceivable heat. I have both set to “automatic” in the remote start menus. My seat will get very warm eventually after I push the start button, but it seems to take longer than other vehicles I’ve had. It’s almost like a delay is there. But, I get virtually no heat with remote start and a few minutes at idle.

It's like a blow dryer trying to warm your whole truck. It's not going to be real hot but it is warm air. My 2020 will thaw windshield. It's about 20 degrees here this morning and have to hit my remote soon because truck sat outside with a trailer behind last night. I'm happy truck has it and wish I could get it on a future gas engine F350.

Yesterday at 6 degrees here in Northern Nevada with freezing fog, I started the truck and it automatically went to high idle of 1200 rpm's. I had the dual temp settings on high for defrost and floor. I noticed the windshield beginning to defrost after about two minutes with an engine temp of about 50 degrees. Rapid heat does work, just not like the regular heat defrost. I was able to drive away after about 5 minutes and engine temp hit 100 after after 2-3 miles down the road. Heated seats and heated steering wheel worked very good also. Truck block heater was not plugged in.

To be fair they didnt have a reason to hide the 17-22 grille. That accessory will be useful year-round on the 23+
For me I always found that any vehicle I had took longer than I'd like to defrost, but the ye olde Alaskan trick of using windshield washer fluid clears that right up.
