I have a tank-type heater and am thinking of replacing it with a
tankless.
One problem is that my present heater has it's water connections at
the top and the tankless at the bottom underneath.
To make installation easier I'm thinking of using flexible
corrugated copper tubing similar to what is used for gas lines.
I'm wondering if I will run into any problems with this, such as
galvanic action, also will the corrugations restrict the water flow
too much?

A conventional hot water heater is a source of drinking
water during an emergency that cuts off your source.

Why would you want to heat hot water, Winnie?
