Replacing an old storage tank type water heater...
I have a large 2-story house and planning to replace the existing storage tank type water heater that uses the natural gas, with something more efficient and maybe smaller.
Since the plumbing has long runs and very often I have to wait for some time before getting the hot water for shower or dishes, what options do I have? I have read about the instantaneous point-of-use heaters and re-circulation pumps... what is the recommendation? Any help is appreciated. BTW I like your site... so many in-dept reviews.
