Comment on Heat pumps can't take the cold? Nordics debunk the myth

  If you are in a traffic jam, you lose range because of the heating. For gas cars, that doesn’t matter at all.

    A 1kw heater (less, given they’re all heat pumps these days) isn’t doing squat to the range compared to an 80kw motor.

    A gas car has to idle its engine to get heat. It’s burning fuel constantly… that’s why you frequently see broken down gas cars in heavy traffic.

      1l/h as I noted further down. Still less range lost relative to the maximal range than in an EV.

        Do you have a 100l tank?

    …where do you think the heat comes from in gas cars?

    Electric heat doesn’t use that much energy. You can be parked for several days with the heat on in freezing weather and be fine.

      From cooling the engine. When you are standing still and the engine is running it consumes about 1l/h. I just looked up some numbers for EVs: 100kWh battery, heating takes 1kW for every 10K temperature difference, so 3kWh in -10°C. Its higher if you use additional stuff like the heating for the seats. With 150kWh/100km consumption you lose 20km every hour you are in the heated car. I would say that’s a noticeable difference compared to no heating. I also checked how much an AC takes in summer and its about 1 to 2kW for 30°C.

        The heat doesn’t use anymore than the AC because it’s the same system running in reverse.
