Personal anecdote:
I bought an expensive Samsung cloth dryer. The more recent ones with a heat pump together with the same segment, Samsung cloth washing machine.
The drier died after 3 years. Everything else worked by it didn't heat, so, it didn't dry.
I called someone to try to fix it, and they said the heat pump was gone and that they see a lot of that. He advised me to buy one that used the old technology of heating the air through an electric resistance. According to the repairman, those are way more reliable (problem is that, while I can live with the increased energy consumption, they need an external exhaust for the moisture).
What is the difference to the electric one? The process is the same up until the point where the hot air with the moisture passes to some sort of cold condenser to transform it back to liquid state? Doesn't the condenser use a heat pump to cold itself?
