Good luck fixing it when it breaks and thus creating more e-waste.
Electric dryers, especially older models, are very simple appliances, you can easily repair yourself and keep them running forever. Can't say the same about heat pump or gas dryer
Certainly something to consider, but they don't fail that often. I've had 1 issue to fix over around 10 years. The cost of that repair over the whole period is ignorable. Once you factor in the running cost, you're just spending more than the maintenance on the energy instead.
