I was sort of thinking the same thing. Though a recirculating pump isn't all the efficient on a tank, but probbably way more efficient than tankless

Some recirculating pumps have timers, so you set them to go when you most need it. Typically you run the circulating line ( hot of course) to the furthest fixture.

This is an easy fix!! Get a shop vacuum and go to the garage-open the area where the debris goes into the bag. Stick the vacuum in there and turn it on. Have someone else check each opening as you do this. You will be shocked at what comes out!!

It’s missing the Flux Capacitor. Home Depot has them on sale.

Hey, I did recirculating pump through cold water lines in an upstairs bathroom. Basically the pump would run for one minute and it was on a Motion sensor. It wouldn’t run again for 30 minutes after initial run. Made it nice for instant hot water in the morning for a shower or washing your hands or whatever.

Unless your house is 30,000 square feet and the furthest faucet is 100 yards away from the water heater....you're talking 10-15 seconds at the absolute "worst plumbing job ever" case for hot water. Just turn the water on and wait... Recirculating a on demand water heater is about the dumbest thing I see on Reddit from time to time....

If you really see the need then put in as efficient a standing tank water heater as you can then recirc that. It'll be much better for the world and for your gas bill since that on demand uses a hell of a lot more gas when its running all day every couple seconds than a standing tank already insulated and hot. Not to mention you are going to chew thru that "MUch" more expensive on demand heater running it near continuous... to save you waiting a few seconds to get hot water at a sink...

Ty. You n the other guy. 👍

TIL. Sounds fantastic.

Edit. Well if it worked, which I guess is OPs issue 😂

It's a system of pipes in your house that is attached to a vacuum motor. So all you do is walk around the house with a hose. Attach it to a port around the gouse and just hit an on button, instant vacuum.

Devil's work. Burn everything 😎

Big vacuum and collection bin in a somewhat hidden location like a garage or utility room, pipes running through your attic and/ or walls to every room, and connection ports in every room to hook up a hose and often a floor tool. The idea is you can vacuum every room without lugging around a tank or upright vacuum, but in reality lugging around a 20' hose can be just as cumbersome.

What the heck is a central vacuum??

I may be wrong but part of it is that it’s super easy to install. You cut stuff to size and snap it together and you’re good. One benefit might be that not gluing or nailing gives the flooring material the ability to expand and contract without buckling (which is why you leave a gap at the edge of the room).

If you want to get some of the benefits of the recirculation system, put the pump on a switch (or even better, a timer switch) near the point of use. Flip it on a minute before you use the water, then turn it off and enjoy your hot water. You're not wasting water or energy then.

Fair enough.

If you have the budget, an SDS drill is a great solution to this. They tend to go where they are aimed!

If you get one with a small tank for the kitchen sink, it can run off 120v. It'll be a heck of a lot more efficient than constantly recirculating.

For the bath as well, if you add a ~2.5 gallon 120v water heater in line with with hot water line, it'll give you hot water long enough for the water from your main water heater to arrive.

I don’t think you’d want to bring exterior concrete up to level with your house. Leave it where it’s at and do your exterior floor.

don't use laminate outdoors, especially if it gets below freezing.. You be better off re tiling the porch with thicker tiling and a new layer of concrete.

Simple fix. Reverse the polarity of the neutron flow.

gotcha, ty!
What's the benefit of doing so compared to glueing / nailing it down?

Floating refers to the flooring material not being glued or nailed down

Right, but tankless+recirculation is a nonstarter in my mind. Your options are tankless and point of use on key fixtures or tank and recirc.
