Installing a tankless water heater ?


I am installing a tankless water heater next to my 50 gal. hot water tank. I am wanting to to keep the 50 gal. heater hooked up but out of service just incase the tankless ever stops working then I would just swap over to the tank heater. Can I just install shut off valves to the tank heater ( both lines at the tank ), and T off of those lines to my tankless , then use the copper flex lines to the new unit ? Want to do this to a standard plumbing code , can a shut off valve be installed on the hot side line of a water heater ? thanks

Yes you can, install the shutoffs in away that will allow you to bypass said heater.

Leave the water heater in place and place the tankless in series after the old WH. The old WH will act as a tempering tank and prewarm the water going to the tankless. You could install a bypass on the old WH if you are worried about a way to isolate it in case of leak or tank failure.

I have seen a tankless installed in the line after the tank heater, and no bypass...the tank heater just turned off.....I would go the bypass...but I suppose a tank heater would probably never develope a leak if never heated, and turning it back on would be as simple as turning the gas valve back on and lighting the pilot.
