[RBS] Seeking information on Gas instant water heating systems

[BM]

Hi,
I am looking into installing a gas operated instant hot water system.
If anyone who has had one installed or done research into this and has any
information that may be useful for me, I'd appreciate if you could let me
know.
Thanks in advance!
Michal
