You have to run a loop. So extra piping har to have a booster pump. Not a Ton of extra money. And have to run the pump constantly. Still not a ton of money but it all adds up

Not really. Grundfos (and others) make a small pump for home use. It's under $200, easily installed, has a timer and uses existing water lines as a return. Best idea, as long as it's not for a shower, is to just install a small electric instahot under the sink.

Electric whole-house units just aren't really worth it but the gas models are. The wait for hot water is not really different than a tank

Yeah pumps don't cost a lot. Running them doesn't cost much. Trying to grasp how you use existing pipe as return piping. We are talking work, outside of work hours, and my brain is fried. I also hate plumbing. I the design. And I hate drawing this crap hahaha. Hence the need for a new job.

It basically uses the cold line as a return with just a small amount of hot always moving. It does raise the temp of the cold water a bit but most are more concerned about hot water. It's run with a valve on the farthest fixture. It's a great little unit for home use and to avoid huge costs installing a full system. Takes a little more work to use it with a tankless heater though

I'm now officially sorry I mentioned my hot water heater issue. They'll be out in the morning to replace under warranty. Lets shift the emphasis to Tex's fake girlfriend and 114's legal issues. TIA

this.

I'm mechanical/plumbing designer (for now) and there is a time and place for instantaneous hot water, but generally not the average everyday home.

I might install instant if I was doing new construction but I wouldn't replumb my 60's house to get it.

Oh yeah. Don't jack with my cold water. It's not cold enough to begin with. I'm guessing it isn't buried deep enough. I like ice cold water and it is a bit too warm.

Sounds like a decent way to get it done for people that Have To Have it. Not a fan though.
