Looking to get a performance model 3 in a few months, any ball park figures on installing the EV charging at home? I've read through the forum and people recommend the nema 14-50...would i be combining this with the tesla wall connector then done?  The wall connector is around $500.  How much would the nema install be?  Any recommendations?

Depends on your needs, i don't remember the specifics, but if you use the small one that comes with the car, it charges about 30 mi/hr, you'll need to tell the electrician to install 220v, 40amps, or if you buy the $500 larger wall connector thingamajig from tesla, it charges the car around 50 mi/hr, which requires higher amps (probably 60 just to be safe) on the wall panel
The reason we have breakers is to protect stuff on both sides of the breaker.  A charger has a specific plug, conservatively sized for the charger's amperage demand.  If the charger exceeds that amperage draw for whatever reason, you'll want the breaker to trip as soon as possible.  At best, there is no benefit to paying 75% more for the material to install a 60A breaker when supplying a 50A receptacle.  At worst, doing so could possibly enable bad things to happen, however unlikely.  Hence, not allowed per the NEC.

The maximum amperage of a Tesla charger can supply a max of 60 amps (48 amps with 80% rule) to the cars.

I thought the discussion was about using a charger that required the nema 14-50 receptacle, which is rated @ 50A.

He was saying some people recommended a 14-50 but went on to ask if a Tesla HPWC made sense. Basically it makes sense if you need the faster charge and if you can put in 60 amps. If you're limited by 50 or 40 amps then go NEMA outlet.

Model 3 refresh
- better range (due to new heat pump like Model Y)
- better performance number (seems like they just updated the numbers to be more accurate, no actual performance increase)
- new wheels
- new center console design
- powered trunk
- chrome delete (anyone done this on their existing one?)

For the uninitiated n00bs - myself being King of them all - why is a heat pump an issue?

(Yes, I could Google all this, but best to hear from an owner/fan IMHO)

It's an issue for colder climate areas.

A heat pump will reduce drain on the batteries.

I haven't researched it either, but wouldn't a heat pump be used for the AC too?  And if it's "NEW" it suggests to me it's just more efficient than the prior one.

I would love to get a Tesla (a Model S) but couldn't really justify it before COVID.  Now...impossible.  We could almost get by with 1 vehicle if I never needed to tow anything.  Life would be simpler and cheaper.

The heat pump / aka Octovalve is not new. It was first introduced in the Model Y and now the Model 3. Here is a article explaining the benefits of the technology:
