We have deliberately chosen not to include a heat pump in our ID.Buzz conversions, despite some of the potential benefits.
In the winter, a heat pump improves range by around 5–8% at temperatures close to freezing - but in most cases, that extra range isn’t essential.
In the summer, a heat pump makes no difference to the range. In very humid conditions,
it can even be a disadvantage, as a heat pump struggles with high humidity and that’s often precisely when you want to use heating while camping.
A heat pump also takes longer (and more energy) to start up and warm the interior.
Heat pumps add 15 kg to the vehicle weight, reducing your usable payload.
They also produce more noise – not ideal when heating the van at night on a quiet campsite.
So, while there are some benefits, we believe the downsides outweigh the advantages, especially considering the additional cost.
