I am keen on no chill method because Im really conscious about water usage & I'm lazy. Transferring wort into a container then letting it do it's thing sounds alot easier (for a newbie) than chilling down to right pitching temp.Any reason you want to go no chill? Every time you transfer your wort, you're increasing the risk of infection and the Robobrew comes with an immersion chiller. I brew wort for a mate and we throw it straight into his fermenter at pitching temperature and he pitches his yeast straight away. The fermenter goes onto his front seat and gets buckled in and we also put a strap around the seat and fermenter just to be sure.
I'd also recommend a bigger fermenter to give you a bit more head space. If you go to your LHBS, you'll be able to pick up something that's completely set up like this https://www.thebrewshop.com.au/catalog/product/view/id/211/s/carboy-fermenter-30-litre/category/50/ The plastic is much smoother than the Bunnings drum, which makes it just a touch less likely that your ferementer will be harbouring bacteria. For the extra bucks, I reckon it's worth the peace of mind.
That fermenter vessel link you showed looks a winner! Thanks for sharing that
