What temp to set heat at before it gets hot?

    So I normally barely ever have the heat on since I naturally am usually pretty warm, but I had a truck full of older cold people tonight and they all wanted the heat up. I went to turn the heat up to about 70 and it almost felt cool. I had to crank it up to about 80 before it got to what I would consider warm/hot. Our 2010 Mazda Cx-9 gets really hot at about 68-70, so are our Tundras just that much different as far as what it takes to put out some heat, or is there something up with my heater? How high do those of you with digital temp control have to turn it up to before it gets warm?

    If I'm in the truck for long periods of time I'll set it between 72-75. If I'm just getting in the truck, after the truck warms up or if it's pretty cold I'll just blast it at hi till it get to hot then drop it down till ambient temp becomes comfortable. It really depends for me if I've also got the window cracked open or not.
    If you've got dual climate which I'm assuming you do since it's digital I'd just set the passengers side higher than your own and that should keep em happy.

    68-70 is not by any stretch of the imagination "really hot" and is actually fairly cool for a house or car. Generally, 80+ is what a heater will blow when the car is up to temp and on full heat.

    Sounds like your Tundra is working as designed and the Mazda isn't. :thumbsup:

    That's what surprised me, though. I synced both sides and had it around 70 and it didn't even feel warm to me, which is weird because I'm so hot all the time.

    That's what I'm thinking. I know 70 on the Mazda isn't really 70 degrees, and those temps on the HVAC dial don't really mean anything unless you have it set on "Auto".

    Most people are comfortable at 70-73 degrees in a work environment. "Warm" is obviously relative and sitting in a car, human bodies do not generate much heat so especially with old people setting a vehicle (or house) to mid 70's is not out of the norm.

    I can't imagine what your heating bill is if your heating your house up to 80 or the strain on your furnace.

    Usually when the truck is at 72 it's not crazy hot but it's warm enough. I'd just crank their side up full blast till they say it's too hot then step down slowly.

    Did I say I heat my house to 80? :eek:

    I keep my house at 65-68 degrees most days, 60-65 most nights.

    Very true. I just need to pretend there's a blue-red dial like on an SR5 and figure out which digital temp on mine is in the far right/red. I never have set it to AUTO and let it try to get to a specified temp, so I just need to ignore the digital numbers and just set it to something that blows warm air.

    That's the first thing I thought when I saw 80+ lol.

    Mine stays at 60 on all zones at all times lol.

    I move mine to the red when I want it hot. Blue when I want it cold.

    70° shouldn't feel warm because 70° isn't warm. Try stepping into a 70° shower sometime. When it's blowing on you, 70° is cool.

    In order to quickly warm a car interior to 70° on a 40° day, the incoming air is going to have to be a lot warmer than 70°. Or you're going to have to wait for a very long time for the 70° setting to do the job.

    But actually, when the temp is set on 70 on a cold day, the incoming air IS well above 70 , once the engine warms up. But if you want it hot, you DO have to crank it up.

    Get a small thermometer to stick in your air vent to see for sure

    In auto mode the heat does not kick on until the engine warms up enough for it to produce heat. For me that’s the front of my development or about 2 miles. After that it slowly raises the fan speed as the engine temp rises so it does not blast cold air. I keep mine about 69 and it takes a while but it gets there. I just use the heated seats until then.

    yep that's my process as well.

    when I had SR5 controls in my 1st gen I typically had the hvac set to floor/defrost and heat in the middle. that seemed to be just right in most conditions.
