I think the tech is just going to simply hook up a brand new stove, no retrofitting of existing stove (not worth it).
Pretty sure the town gas people want some kind of certified installation, don't want people doing it themselves (can't blame them)...
Still seems kind of like something that should be "built-in" by the landlord but, yeah, HK landlords are not known to be the greatest...as a landlord in the US, I think I am required to provide a stove...anyway no one would rent without one so, yeah, I provide a stove...
BTW, I was told by my contractor that any gas stove has to be installed by licenced TG staff. Also TG stoves give higher heat than other brands, hence better for Chinese cooking style.
when i was in singapore, the piped gas were more expensive than the cylindered gas.. so obviously the payment is for the convenience and storage and etc.etc.etc..
does it make alot of difference ? I think if you already running a gased water heater, then don't see any point in insisting on a cylindered tank just to make it cheaper.. likely not going to move the needle much.
