Switching water heaters

Hi Friends

I recently installed a tankless water heater only discover it does not suit us. It is too small and has 1/2 inch inlet and outlet so there is a considerable drop in pressure, especially during showers.

So I am going back to a regular WH.

Question: any problem connecting the WH to the 60 amp breaker and 6 gauge wire I installed for the tankless heater?

Yup, there is an issue with using a larger breaker than required. You can keep the 6ga wire, but the breaker needs to be swapped out with a double-pole 30A.

Sorry to hear the tankless did not work out for you but that's a common theme, they're a lot better on paper than in the real world.

With 1/2" inlet, outlet, and only a 60A breaker, it sounds like the OP has a point-of-use heater. It doesn't work because it's simply too small. That's not the heater's fault. We have a whole-house gas tankless and love it.
