Is Taycan heater as good as ICE heater?

[ovonrein]

We all have this problem. I needed to resort to the manual to solve it. Select "Individual" in the air con settings, then icons appear at the bottom where you can select where air should flow. Turn off feet and chest so that all air is directed at the windscreen. You will now have to control the fan yourself. I set it to the highest speed where its din remains below the tire rumble. This is slow. 4, perhaps 5. Now compensate for the slow airflow over the freezing screen by cranking up the temperature. On a recent drive I kept the screen free and cabin at 20C by having the heater direct 24C at the windscreen.

Aircon in Auto is totally hopeless in these situations.

PS: If in a hurry (because you perhaps forgot to precondition), select air recirculation until the cabin is at temperature.

My big problem is frozen window drops in below freezing wet weather

Mine too. The preheat has to be on for a long time before the windows free up if the car is outside.
I did think of coating the seal with vaseline or something but don't know if it would react chemically and anyway, always forget before it freezes.

Who are you replying to?
If it is the OP I don't have that problem, I have left my heater in the default setting it was delivered with except setting it to Eco and 21C and it has never needed adjusting to have clear windows and comfortable temperature in over 3 years (except when the software crashed)

Works perfectly in mine.

I preheat mine so it’s warm (and de-iced) when I get in. Can’t do that with an ICE.

I do if it is freezing outside, otherwise it still gets comfortable from cold much quicker than any piston engined car.

I have discovered that I can use a very thin piece of metal, specifically an eraser shield and slide it between the glass and the seal. The thin stainless sheet breaks the bond between window and seal without damaging the seal.

I use a credit card or some shop card or other to clear the window from the seal when frozen - been doing this without problems since I had my Spider with frameless windows and auto drop in the early 2000's.

The heater is 10kW maximum, so not as much as you can extract from the cooling system of a piston engine, OTOH it works immediately so the heat up time is obviously faster than with a piston engined car starting with a cold engine*.
Once the piston engine is warm it has more potential since about ⅓ the power comes out of the crankshaft, ⅓ goes into the coolant and ⅓ comes out of the exhaust.
Having written that I find the Taycan heater excellent and the cabin quickly at a comfortable temperature.
Once the car has been going a good while (a lot longer to warm up than a piston engine because about 3x more efficient) heat can also be extracted by the heat pump to make it al ittle bit more efficient.

* Unless it's a 911, which takes (instant) heat from the exhaust manifolds!

Classic i.e. (very) old 911

@Bennachie *GummiPflege. Sounds good.

It can afford to be, with this much heat going to waste.

Yeah, I’m kind of confused by the efficiency responses as they’re both inaccurate and don’t answer the OPs question.

The impact of using a heater in an ICE vehicle on range is almost nothing. The fact that a lot of heat goes out your tailpipe doesn’t matter as it would whether you turn your heater on or not.

The impact of using a heater in an EV is significant.

For the OP, our heater is both “better and worse” compared to an ICE. Better- heats up instantly. Worse- won’t get as warm, sacrifices range, and a heat pump doesn’t work very well in extremely low temperatures.

Heated seats are your friend.

Yes you can- remote start. Lots of people do that when it’s cold (or hot and run the AC).

Either from your key fob or app.

I have not given that aspect any thought. There was an earlier post that stated that switching off ECO (which engages the heat pump) improved heater performance in cold temps. Perhaps the heat pump is the reason behind that observation. A heat pump begins to subtract value before the point at which efficiency falls below 1.

They don’t but are not pulling from the ambient air but from the heat generated by the drive train after an initial warming up period. Think they might use electrical heating up to that point.
