If you're lucky, it'd only spoil within the warranty period. If after, it will cost you.

I own the 9kg model. Get warranty extension if you could, just to have peace of mind.

Drying cycle varies. It detects dampness on clothes too. Usually 2 hrs for cotton. Less for the rest.

Heat pump consumes the least amount of electricity in term of dryers. So don't worry much about the bill.

Get a more warranty extension from more reliable store. Cross fingers that it doesn't have problem.

All the best! I still love my driver, but it's in workshop now. 🤣

I m using condenser type. It is so minimum power consumption.

Read and understand the technology behind this 3type.

That is the heater watt. Not how it work to save.

I read several sites the heat pump could take 3-4 hours more compared to the vented type. End up the savings might not really a huge gap

For example
Vented 2.4 kw x 2 hrs drying time, 4.8kWhr
Heat punp 0.9 kw x 4 hrs drying timr, 3.6 kWhr

It might take quite a while to offset the high cost of the heat pump unit, not to mention the extra time to dry with the heat pump unit

Daily usage? 1 cycle per day?
