Lower Heat Isn't Hot
 

Anyone find that leg/lower heat/heater isn't hot?

This is after full warmup and compared to full blast of hot air for upper air alone, the lower heat alone is about 23 degrees celcius at most (room temperature) and at least half as weak in blowing the air out.

Close the vents you're not using, if any. I rarely have passengers (their loss), so I close the right vent in the center and the passenger side vent by the door, and that increases the airflow to whatever else is still open.

I don't think the floor heating is bad when the car is at optimum running temp. This car actually has some of the best heat I've had in a car besides my old Corolla. Feet get toasty pretty quick from my experience. Sometimes I switch to it just to spread the heat out a bit, rather than turn the temp down, so my knuckles and face don't get cooked by the upper vents when I have the heat set to Hell.

Are you using the fresh air setting or the recirculation? It does make a bit of a difference, and if your cabin air filter is clogged up that will affect the airflow in the recirculation setting.

Cabin air filter affects both fresh and recirc. You're good as long as you can see light through it.

That so? Suppose I stand corrected, then.

Maybe the lower vent isn't being opened up all the way...... :iono:

Have you been messen around under the dash lately ..??

I can see light through chicken wire ...... :D

Why do chickens lay eggs with different colored shells, when they are penned and all are fed the same chicken feed ...... :iono:

No worries, brotha. :cheers:

Why does chili taste better the next day?

Chili taste better the next day because the next day you hadn't gotten tired of messen with it and tasting it all day long.

Plus, time has allowed the flavors to come together.

Now, what about the egg shell thing ....... chicken farmer ??.........:iono:

Like a dog on a bone, ain't ya.

Hell, I dunno. They both scramble the same. That's all that really matters.

Color of eggshells is determined by genetics, much like the color of human hair. Some colors are dominant traits while others are recesifs, so the probably isnt a 50/50 split. What was this thread about again?

Floor heat? Eggs? Floor heating your eggs?

Personally, I think this car has one of the best heating systems of any car I've had. There's heat at the vents within a minute or two of driving, and it gets hot enough to bake a potato.

Yes I noticed the same thing and found it strange.
The floor heat is noticably colder than the top vents, and when the aiflow setting is low, there is not a lot of air coming out the floor.


For the temperature maybe it's intentional design. In cold climate most people are wearing boots or insulated shoes during winter, so if the air at your feet was the same temperature than the one blowing at your hands/face, then your feet would be really hot with the boots and all.
But it could be a bit warmer.


PS: I have automatic climate control, but use it mostly in manual mode.

Back on topic, yes, I've also noticed the same.

The upper vent blows hot when the mix is full cold with no AC. On my own I've just decided it's due to the black dash and that it just gets really hot in there. :iono:

I have to think at full cold with no AC the air is warm just because of how much heat our engines generate. I've noticed if I'm in motion the air will cool a few degrees, but still not comfortable, and once I stop it gets hot again as the ventilation sucks in hot air bleeding out from under the hood. When I first start the car and it isn't warm yet, I can get pretty chilly air from the vents, but once the car gets warm there is a notable change in the air temp from the vents, and even more of a change once you've stopped moving. Forces me to use the AC more often, as I'm not much of a window-open driver unless I'm autocrossing.

As for heat during the cold months, though, I really can't complain. I quickly reach a point where I have to lower the temp setting to keep from getting way too hot in the cabin.

Yes, the hot air even on cold setting is something I really don't like about the HVAC.
A lot of time the outside air would be the perfect temperature, but I still have to use AC because the vent blow hot air.
I dn't like opening the windows on the highway.

Yep, that's a common complaint, especially with owners of Miatas. Maybe it's a small, low, car thing .....:iono:

Haven't messed around with anything. Didn't notice there is a vent there can be opened/closed for lower vents. I don't do recirculate.

I'm in Canada and it's cold right now. At around 0 degrees celcius. My heating system only kicks in after 10 minutes.

Will play around with it and mention it to dealer.

Oh, I've noticed that my FR-S doesn't heat up the vent air for about 5-10 minutes ....... and it doesn't get real cold here.

A couple of years ago there was a post about the low airflow out of the lower vents. If you get down there you'll see that it's a small opening and the air needs to blow over a bunch of parts, the cold coming through the tunnel is significant too and really cools the footwells. When it's super cold if you're on a long highway trip it's pretty much impossible to keep your feet warm. I've done a couple of long trips when it's in the single digits and it just plain sucks trying to keep my lower legs and feet comfortable.

My grandson figured this out last winter. Even though there is plenty of warm air blowing on the feet it is countered by the cold air coming under the seat from the rear. I just wadded up a blanket and filled the gap under the driver seat and my feet get nice and toasty warm in a few minutes. Give it a try if you have cold feet.

Floor heat has never really worked that well in my BRZ. I love my Integra in the winter, it blows more air and more heat onto my freezing feet. Miss that feeling in the BRZ

I test drove a few '17 BRZ Limiteds, they all seemed to be severely lacking in warm air for the feet :( bought one in spite of this, but it is pretty damn annoying...
