A heat pump dryer is 4x as efficient as a resistive electric dryer which would reduce your operating costs by 75%.
In the real world, to get my clothes dry, my heat pump dryer uses ~1.5 kWh (at at least 2 hours) vs ~2-4 kWh with an older dryer. Yes, I've used watt meter.
I'm sure /yours/ is magic tough :-)
They're good at reducing peak load on the grid, sure, which is useful.
[0] The manufacturers join in the with this nonsense by lying about the clothes being dry, and gating the "actually dry" setting behind some advanced menu. They expect you to do the last 10-15% of drying in your wardrobe or something.
