Adding a heat pump into 2018 Leaf SV ?

Wed Dec 12, 2018 1:44 pm

Is this possible to add a heat pump into 2018 Leaf SV ? I have a Technology Package.
No All-weather package which has the heat pump.

With winter weather in Colorado, we noticed significantly reduced Leaf range.
Surprised with LeafSpy showing that the heater can use up to 2.5kW ! That's a lot.

Our sales person hasn't mentioned anything about the Heat pump.
We purchased Leaf 2.5 months ago.
I just learned the hard way what we're missing.

I understand that heated seats/ heated steering wheel are "hardware" features.

But do you thing that the heat pump is just a software feature? :idea:
Reading online, it seems a heat pump is "just" an AC working in reverse, isn't it?
I think it would be a manufacturing nightmare to cook two separate AC units
with and without reverse functionality...
If that's true, heat pump I guess could be activated by Nissan (after paying a fee,
less than All-weather package as I still wouldn't have heated seats and all of rest of that package).

Thanks!

The hybrid heater '13 to '17 US Leafs (SV and SL trims) have a reversing valve. I doubt that's on the S trims which don't have the hybrid heater.

'19 Bolt Premier
'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

The heat pump isn't software - it's definitely hardware. Your car has a resistance heater plus an electric air conditioner. The cold weather package would have added a heat pump in addition to the resistance heater, replacing the A/C unit. As for whether you or a mechanic can make that replacement...that's a good question. I'd wager a small amount on "no."

Nissan should never have sold the Leaf S in cold climates. That they have made things worse by making the heat pump an option on the SV borders on criminal.

Absolutely. The ‘18 Leaf I test drove was a stripped SV without the weather package. That was a miserable cold 20 minutes compared to the ‘14 SV I used to have. Took it back and politely told him no thanks. Fortunately I’m not in any hurry, can wait until their ‘19’s start showing up in a couple months.

someone with an '18 should not be complaining about range with any heater... They just need to not blast the heater... I always set the heat to 68 degrees and the fan to 1... no problem

@powersurge, '18's heat pump is the same on '17 and older models, no?
