Only option for Integrated Dryer is Heat Pump, which is quite expensive. all loads so far have taken around 2.5 hours - not much longer than old vented dryer, but appears to be cheaper to run. Large drum, not particularly noisy, controls are straight forward, easy to empty water and top fluff compartment, no signs of any condensation. Only downside is that there's a second fluff compartment behind the plinth, which will need to be removed to give access - not tried to empty it yet - display will give an alert when it needs to be cleared.
