Removing water heater

I need to remove this water heater. This may sound stupid but how would you go about disconnecting the old heater? Would you just cut the pipes near the in and out, remove the heater and then heat the cut pieces, remove them and install and sweat new ones?

Would you heat the joints by the in and out and pull them out?

Should I use flexible water supply to reconnect the new water heater?
Thanks ahead

Do you have any plumbing experience at all? You are missing some basics. May I suggest to find a friend to help you. After that, you know how to do basic plumbing jobs.

Don't cut the pipes close to the heater. They should be threaded into the heater itself so you unscrew the those sections. Also, you didn't mention the gas pipe. You have to know how to connect that too.

Thank you and no disrespect but that wire coming out of the side of the heater is for the electric heater elements

The pic appears to be 90 degrees rotated. I didn't see the wire.

Wow... that is a lot of plumbing. It looks like the water heater is the focal point of the water system.

How you remove the old one is based on the setup of the new one.
Is it exactly the same setup.... same dimensions ?

Yes.... I would cut right at the water heater and then remove the pieces from the existing plumbing. You need to be careful sweating the lines too close to the tank. You should solder the threaded fittings on your two new pieces of pipe, install the threaded pieces with the stubs into the W.H. and then sweat on the plumbing system.

Make sure the old stuff is cleaned good or you'll have problems with the solder flowing.

Ditto...

I would cut close to the heater..

But since they put brass couplings on it with nipples I would replace with unions. Then you can thread onto the copper male adapters and not have to solder.

Make sure you use brass or copper unions and brass nipples...

PJ and Lawrosa are correct. You can cut the inlet and outlet almost anywhere. But I would use Sharkbite heater connectors for the inlet and outlet. I would also try to clean up that rat's nest of piping.

I'm not sure that's a rat's nest -- it looks like there a lot going on. Some tempering, recirculating & whatnot. If it's not put back the right way, something may go askew.
