Heating questions

Hi

I'm about to order my first E-class and have a couple of questions

1. I've decided to get auxiliary heating. Those of you who have this installed: do you find this enough to be comfortable on cold winter mornings or does also having heated windscreen and steering wheel add anything?

2. About the rear seat heating. Do you switch it on for the entire rear seat or can each outer seat be controlled individually?

Hoping that you MB experts here can help me with this

Both outboard seats have a 3-position controller. I guess a center passenger goes cold.

Just wanted to be sure what you mean by "auxiliary heating". Do you mean heated (front) seats? Also, I don't see heated windscreen (other than defroster) listed as a U.S. option.

I'm specing out a 2020 E Wagon, and was wondering, along these lines, something similar, which may also be of interest to you:

The Premium Package includes Heated Front Seats, yet there are separate selections for Rapid-Heating Front Seats, which is also a feature in the Warmth & Comfort Package. Is there a difference between Rapid-Heating and Heated Front Seats?

I've been reading a 2019 E-Class Operator's manual, and it appears that when you order 3-Zone Automatic Climate Control, that you lose the Sync feature for the driver and passenger zones, that button being replaced by a Set Distribution mode for the passenger. I'd really prefer the Sync, to make driving alone more convenient. Any experience and comments about this?

Auxiliary heating is an option for cold climates that has a separate burner that runs off engine fuel. It is not available in the US, so OP will need to have European owners supply the answer to question 1.

And yes, rapid heat seats are a different option than regular heated seats.

But they appear to be controlled with the same 3-stage button. Do they just heat quicker (using more electrical current)? I've had and used heated seats in an Avalon and Acura; are the standard heated seats sub-standard, with the rapid heating ones necessary or more desirable?

They just heat faster. My wife is a butt-warmer addict and I ordered the rapid-heat seats in order to get her to be okay with the 3-D Burmester. Marital negotiations.

Like user Whoover said, Im referring to the fuel-based parking heater. Heated windscreen is perhaps also not available in the US, but it is an electric defroster.

The manual seems to imply that the sync feature for thermotronic is available through the menu, but not as a button. Is this correct?

That's a win-win. Pretty good trade-off.

Assuming the Thermotronic is the same as 3-Zone Climate Control (now that I know there are differences like this in other non-US areas), the manual doesn't say much, except what buttons are available. I'm sure that the menu may provide Sync, but am just saying that using Sync seems like something used much more often than manually setting the Air Distribution mode differently for driver and passenger. I normally only use Auto and just set the Temperature. My passengers simply adjusts their temperature as necessary. I would much rather have Sync, which I use, than Air Distribution, which I don't. It seems funny to me that the 3-Zone Climate Control makes this change when it has absolutely nothing to do with the 3rd zone.

I had 3-zone climate on an S-Class and have not ordered it on subsequent cars. The extra hardware takes up storage space (it did make the center console storage smaller, and may still) and was rarely used. The air flow in the back with dual-zone is adequate and I have never had rear passengers who found the temperature uncomfortable when the front passengers were ok. In the limited volume of a car, temperatures tend to equalize quickly anyway. Earlier models had a Zone button that explicitly synced all three zones. If SYNC is deactivated when a passenger adjusts the temperature, it would be very tedious to have to reactivate it through COMAND.

This feature makes sense in a large chauffeur-driven car but not in a family sedan, in my opinion.

Having an European W213 with auxiliary heating, heated windscreen and heated steering wheel I can only advise you to order them all. The windscreen very quickly becomes ice-free and that is very comfortable if you don't have enough time to let the auxiliary heating heat up the car. I love the heated steering wheel because although the auxiliary heating heats up the car, when it is very cold some materials (like the leather on the steering wheel) stay cold a long time. For this reason I can also advise the winter-package in which the armrests are heated as well.

With the 3-zone Thermotronic the SYNC function is operated by pushing the big menu-button in the console and confirming SYNC which is the first option.

Easy.
I would order the heated steering wheel AND Rapid heated front seats with heating in arm rests. I'm really missing the heated steeringwheel in my car but it was not an option on E63S when I ordered.
Heated windscreen sucks, you can see the heating elements in the windscreen. I just hate it.

The Mercedes heated windshield does not have wires as heating element. It is an invisible foil.

It's not invisible. I've of course tested it and ordered my car without it.

I don't know what you have seen but this is a new feature for the E-class which was introduced in MY2019 in my country. I have it and I can not see anything. No wires, no strips, no deformation, nothing. It's not available in the US.

It's the same technology used in the W222.
My dealer said it was an option I could order for my 2018 E63S, I skipped it.
