I can remember that someone else mentioned having a similar problem, but can't remember who I'm afraid. I'm sure Tesla will get it sorted if you get in touch with them though.

 

Yes, I have the same problem with my old, (9 months) model S. It wasn't bad until v7 arrived now it's very erratic, particularly on long journeys. I set the temperature high, turn the air con off and point the air flow at my feet. After a while the car gets too hot so I have to start 'messing' with the setting again. I'm trying to get mine booked in so that Tesla can have a look at it.

 

I think this is 'an EV' thing. To save energy, the coolant is only just warmed up to 60C or so. By the time that is blown around the cabin, it makes the average temp OK, but we're used to ICE coolant systems where 80 or 90C is the norm, and so if you check most people's settings in winter they probably have 30C odd at their feet, with that drifting upwards into the cabin space for an average 20C or so.

I've noticed on the Ampera how the electric heating is 'OK' and on average is nice enough, but what I really hunger for sometimes (I blame elderly circulation!) is just to run the engine for long enough to produce the intense pool of heat around my legs that you get with an ICE!

 

I think the heat pump used in the Gen2 Leaf is a much better solution - you can really blast out a lot of warmth very quickly and it doesn't suck the life out of the battery to do it.

 

I only got to drive it from the pick up before I have lost it again for a week.

But I did notice that it started off warm but after 10 mins started to blow cold air, I thought it was me and was doing something wrong, was going to do more testing when I get the car back.

 

Compared to an ICE? - like my old Jag where you had to drive around 3-4 miles from cold before any trace of heat was felt.

 

This is a bug in the current version of the v7 firmware (which was touted as having "heating system improvements"). Apparently it's fixed in the next version.

 

Thank you all for your comments. I will wait until v7 is replaced and see if it helps. I am glad to know I am not alone. Incidentally, my husband is also finding the same thing even with his long-johns on!

Happy electric New Year everyone.

 

I went for a 140 mile drive today and noticed it also. I am wondering if the car is recirculating the air when the cabin is warm enough, with no additional heating added in that air, and so you just feel a draft of the air movement?
We might be suffering from ICE thinking - our historical thoughts might be fooling us into thinking a higher fan speed to the feet will cure things, when in fact a slower speed not aimed at the feet might help?

I keep mentioning it - use the slowest fan speed you can (which is just fast enough to help avoid too much fogging) because whatever warm air you push into the car means warm air is being pushed out somewhere.

Set fan speed to lowest, then adjust the temperature setting to get the cabin conditions you want. It's better for energy economy to have higher temp setting and lower air speed than the other way around.

 

Mine is an early 2014 Model S with latest software and its 9 degrees F here and my feet are never cold. The recent update seems to have made the cabin temp worse but I think a later version is supposed to improve that.

 

I have also noticed that my feet get cold. I have to force the air to the footwell and turn it up to 26 degrees to solve the issue. Let's hope the next update helps.

 

New software (which comes with lauch mode in PD models) has much better heating, I am warm at 21!
