Which brands of heat pumps are particularly recommended?
Do you want the whole technology and especially operation to be simple and successful on the market for a long time? Then, for example, Panasonic – designed so simply that it is also the brand for do-it-yourselfers. But also very efficient and durable.
If you want it complicated, then take a look at our German flagship products ==> the thread about Vaillant Arotherm Plus VWL is a good example of that.
By the way, you pay significant price premiums for the complexity compared to the Asians, but you also have plenty of craftsmen who at least carry the brands.
In another thread, I named an example of a complete installation of a Panasonic heat pump. Offered by the installer with a flat rate of €19.5k
before subsidy and including removal of the old gas heating system. Delivery times for the devices are currently 3-5 working days.
Otherwise, the correct sizing of the heat pump is more important. If it runs without major switching on and off, the brand doesn’t matter – just don’t take exotic ones where the next factory service maybe 500 km away (see thread about Ecoforest).
