Utterly reliant on ours with the amount of laundry that DS2 generates. Even used it for his bedding when it was warm, yesterday, as whatever pollen is about at the moment is making his eyes stream. We do have a heat pump one, as the condenser dryer that was much, much better than our previous heat pump died and was costing a fortune to run when the energy bills sky rocketed. It takes 3 hours to dry a load in the middle of winter and I get sick of listening to the bloody thing all day.
I do miss the say the old condenser dryer heated the kitchen up.
