We’ve got a john lewis branded heat pump one. Very good with a big capacity. Not slow either. But it is very sensitive to fluff build-up and there are 3 filters to clean after each use.
As above, pre-kids we barely used a tumble drier. Now with kids it’s on everyday outside of the summer months. I reckon kids produce c.4x the amount of washing that adults do. So on that basis, a drier with the lowest operating costs seemed sensible. We don’t have mains gas, so that leaves only heat-pumps as the lowest power use options.
