[recycled sixtie]

We had our water tank/heater(nat. gas) replaced in June. Our insurance co. said that it being over 15 years old they could not insure the basement/contents any more. Guessing it was about 17 years old. We got a good plumber to recommend one. He said to avoid Chinese water tanks. Presumably they don't last. We got a John Wood one made in Canada.

As regards the tankless I believe they are expensive to buy initially.
