Should you buy an EV with a heat pump?
In our winter testing it was the single strongest predictor of how much range a car kept. If you drive through cold winters, treat it as a specification, not an option.
A heat pump is frequently an option box on the order form and frequently the most valuable one on it.
What it does
A resistive heater converts electricity to heat at about 1:1 — a kilowatt in, a kilowatt of heat out.
A heat pump moves heat from outside air into the cabin rather than creating it, and can deliver two to three kilowatts of heating for one kilowatt of electricity.
On a car spending 3 kW on cabin heat, that is a very large fraction of your winter range.
What we measured
Across 14 cars below 5°C, against the same route in mild conditions:
- With a heat pump: −12% to −22%
- Without: −28% to −43%
The full method is in winter range: what we measured. The gap was consistent enough that a heat pump was the strongest single predictor in the data.
What that means in miles
A car quoted at 250 miles:
- With a heat pump: roughly 200 miles in winter
- Without: roughly 145 miles
That is not a rounding difference. It is the difference between a journey needing no stop and needing one.
Where the advantage narrows
Below about −10°C most heat pumps supplement with resistive heating, so the gap closes at genuine extremes. For typical UK winters, and most of the US, it stays firmly in the heat pump's favour.
Is it worth the option price?
If you drive through cold winters, almost always. The option cost is usually modest against the range it protects, and it improves the car's resale appeal — buyers increasingly look for it.
If you live somewhere genuinely mild and drive short distances, it matters much less.
What to check on the order form
Confirm whether it is included on your specific trim. It is often standard on higher trims and optional below, and the brochure headline does not always make that clear.
On a used car, confirm it was actually specified — our used buying guide covers what else to verify.

Common questions
Can one be retrofitted?
Effectively no. It is an integrated part of the thermal system, not an accessory. Buy the car with it.
