Mid-January, on the E40 between Brussels and Ghent. The temperature reads 3 °C, a light drizzle is falling, cabin heating set to 21 °C. My dashboard shows 72 % charge at departure. Fifty kilometres later, I am at 60 %. A colleague on the same commute, same Enyaq — but without the heat pump — went from 72 to 55 %. Seventeen percentage points of difference on the same winter drive. The heat pump is not a marketing gimmick. It is a piece of hardware that changes the equation when temperatures drop.
What is a heat pump in an EV and why does it matter?
The heat pump (HP) does for cabin heating what a turbocharger does for a combustion engine: more output from less input. Instead of brute-force converting electricity into heat (resistive heater, COP of 1), the HP harvests thermal energy from outside air and amplifies it. Its coefficient of performance (COP) reaches 2 to 3 in Belgian conditions (2-7 °C). In practice, to heat the cabin to 21 °C when it is 5 °C outside, a resistive heater draws 3 to 4 kW continuously. A heat pump does the same job with 1 to 1.5 kW.
On a 2-hour drive along the E411 in winter, the difference is measurable: 6 to 8 kWh consumed by the resistive heater versus 2 to 3 kWh by the HP. That is 4 to 5 kWh saved — roughly 20 to 30 km of range preserved, from the heating system alone.

How many extra kilometres does a heat pump deliver in a Belgian winter?
The real-world data is clear. The ADAC Winter Stress Test (2025-2026), conducted between -3 and 7 °C — precisely Belgian winter conditions — shows significant gaps between EVs with and without a heat pump.
| Model | Battery | Summer range (20 °C) | Winter without HP | Winter with HP | HP gain |
|---|---|---|---|---|---|
| Hyundai Ioniq 5 LR | 84 kWh | 340 km | ~245 km (−28 %) | ~280 km (−18 %) | +35 km |
| Tesla Model Y LR | 79 kWh | 390 km | ~290 km (−26 %) | ~330 km (−15 %) | +40 km |
| Skoda Enyaq 85 | 77 kWh | 370 km | ~255 km (−31 %) | ~300 km (−19 %) | +45 km |
| VW ID.4 Pro S | 77 kWh | 350 km | ~240 km (−31 %) | ~285 km (−19 %) | +45 km |
| BMW iX1 xDrive30 | 65 kWh | 310 km | ~215 km (−31 %) | ~260 km (−16 %) | +45 km |
| Kia EV6 LR | 77 kWh | 360 km | ~250 km (−31 %) | ~300 km (−17 %) | +50 km |

The Kia EV6 benefits most from its heat pump with 50 km recovered, thanks to particularly efficient thermal management co-developed with Hyundai. The Polestar 3, not shown here, records only 5 % winter range loss in the Norwegian Automobile Federation test — but it is a premium model at €70,000+.
Which models come with a heat pump as standard in Belgium?
In 2026, the trend is clear: the heat pump is becoming standard on mid-range and premium models. But it remains optional — or absent — on entry-level vehicles.
| Brand | Model | HP standard | HP optional | Option price |
|---|---|---|---|---|
| Tesla | Model 3 / Model Y | Yes (all versions) | — | — |
| Hyundai | Ioniq 5 / Ioniq 6 | Yes (from Creative) | Intuitive: no | — |
| Kia | EV6 / EV9 | Yes (from Active) | — | — |
| BMW | i4 / iX1 / iX3 | Yes | — | — |
| Renault | Scenic E-Tech | Yes | — | — |
| BYD | Seal / Seal U | Yes | — | — |
| Skoda | Enyaq | No | Yes (Winter Pack) | ~€1,000 |
| VW | ID.4 / ID.7 | No | Yes (Comfort Pack) | ~€1,000 |
| Cupra | Born | No | Yes | ~€900 |
| Dacia | Spring | No | Not available | — |
| Citroën | ëC3 | No | Not available | — |
If you are choosing between two trim levels of the same model and the heat pump is the differentiator, take it. At €1,000, it pays for itself in 3 to 5 Belgian winters for a commuter — and it improves heating comfort from day one.
Is the heat pump worth it for a daily Belgian commute?
The maths is straightforward. A typical Belgian commuter: 60 km round trip, 5 days a week, October through February (roughly 100 working days).
Without a heat pump, cabin heating draws about 2.5 kWh per 60 km winter trip. With a heat pump, that drops to 0.8 to 1.2 kWh. The saving: 1.3 to 1.7 kWh per day, or 130 to 170 kWh per season. On a longer commute (Brussels–Namur, 120 km/day), the saving rises to 260 to 350 kWh per season.
At the average Belgian residential rate of €0.30/kWh (Brussels, 2026), that is €40 to €105 saved per winter. For an optional heat pump at €1,000, allow 3 to 5 winters to recoup the cost. If it comes standard, every saved kWh is pure upside.
But the real gain is not financial. It is the range recovered. When you are driving Brussels to Liège on a December evening (100 km via the E40) and your battery sits at 45 %, those extra 40 km from the heat pump are the difference between arriving relaxed and scrambling for a charger near Bierset.
The heat pump does not change the size of the battery. It changes what you can do with it when the thermometer drops below 5 °C.
How to get the most from the heat pump in a Belgian winter
The heat pump does the heavy lifting, but three habits maximise its effectiveness:
Precondition while plugged in, always. Start the heating 15 minutes before departure via the app (Tesla, Bluelink, Kia Connect, myŠkoda). The cabin reaches 20 °C, the windscreen is defrosted, and the battery has lost nothing — the grid paid the bill. The heat pump then takes over while driving to maintain temperature, drawing minimal power.
Park indoors when possible. A garage at 8 °C instead of -2 °C outside: the battery starts warmer, the heat pump reaches its optimal COP faster, and defrosting is unnecessary. According to ADAC, vehicle starting temperature affects consumption over the first 20 kilometres by 15 to 20 %.
Use heated seats and steering wheel. Heating the body directly draws 50 to 100 W per seat, compared to 1,000 to 1,500 W for heating cabin air. Lower the thermostat by 2 °C and switch on heated seats: range improves by 5 to 8 % according to Recurrent (2024).
Le verdict de Christophe F.
In Belgium, the heat pump is a rational choice, not a luxury. Our winters between 2 and 7 °C fall squarely in the HP's optimal efficiency zone. If your model includes it as standard, you are covered. If it is a €1,000 option, take it — especially if you drive more than 40 km per day in winter. The only scenario where it makes no difference is if you only drive in summer. And in Belgium, summer lasts about three weeks.
