Which is better.... hot water circulator or small hot water tank at location of house which needs it? My house is 4600+ sq/ft and one side of the house takes 5 minutes plus to get hot water.

@pianodannmarr This pump comes with a bypass valve that's installed at the furthest fixture. It uses the existing cold water line in the house to return the cold water in the hot water line TO the cold water half of the system. When it senses that hot water has made it to the fixture, it turns off the bypass valve.

@ndyt The video omits this excellent point! A separate return line for all the fixtures with bypass valves? How much is that going to cost? Don't waste your money, just wait for the hot water to reach the fixture.

@AsktheBuilder Checked your website today. Just realized it was -your- website that gave me the idea for a gravity system awhile back - thank you! Still need to post an article on youtube as I couldn't find a single one that was gravity, only those that use recirc pumps.
Installing the system was easy. Installing more than 100ft of pipe insulation was the worst part.

You really need a separate return line to get this to work without heating your cold water. That's not going to be easy for most houses though, but if it is doable for you then that's the way to go.

Basement installation so why go with a pump at all? With the simple installation of one long pipe in my basement - my shower that is 70ft away always has hot water right away. And never any hot water in the cold water line, either. Need to show a gravity hot water system - I love mine!

@GPE001 I have numerous columns at my AsktheBuilder site, the dot com one, that show you exactly how to install a gravity loop system.

It is also a good way to make your water heater work harder, the longer it took to get hot water to your shower, the more heat loss you will have in your plumbing when you circulate hot water through it. Put that in a hot climate and you are plain stupid. If people would use their shower water for their yards, they wouldnt really be wasting anything by waiting for hot water. This is just a dumbass "luxury" item that wastes more in electricity and lost heat, then it could ever save in water.

@d1incharge Aren't you glad you live in the USA where you have choices like this?
