how to install a recirculating hot water pump in your house so you don;t have to wait for hot water?

Question

like do you put the pump into the return line to the house or into the line going into the hot water heater or a web site I can go that explans it or has a viedo

Answer 1

a recirculating hot water system requires a loop. pipes running from the hot water tank
to all the outlets, then back to the tank, then a short pipe feeds to the faucets, so your talking about a lot of expense,
plus the pump. not cost effective unless there is a long run for the hot water,

Answer 2

I just put one in my home and did not use a pump. Mine is strictly gravity. I cut into (with a tee fitting) the present hot water feed line at a point which was farthest from the water heater and then bring a new line back to and teed into the drain at the very bottom of the heater. I put a shut off valve in the line just "up" from the new tee near the drain so it can be adjusted or shut off if needed. (Mine is open and has been since I installed it) Some systems may require a check valve in the new return line on the horizontal part of the return line near the water heater. I put one in but it wouldn't allow my system to work so I removed it and all is well now. All you are doing is making a loop so the hot water is always circulating from the heater thru the feed lines and when it cools a bit it returns by gravity to the tank. This is the very best thing I have done in many years. This gives you Instant hot water and no pumps, no electric use. You can read about this system on the web. Just Google for it. Good luck

First question would be, do you already have a loop system in place? If you do have a loop system, the pump is usually installed at the bottom of your water heater in place of the boiler drain, pumping into the water heater. Very Important is to also have an expansion tank installed, in case there is a pressure build up in your line. Best thing is to have a plumber properly install this setup.
If you do not have a loop system, there is a way to create a hot water loop system. A company called GRUNDFOS has created a circulating pump that attaches onto the hot/ outlet side of your water heater. Then at the lavatory or faucet, furthest away from the water heater, a bridge fitting is installed, turns the cold water line into your return water for your water heater. Now your hot and cold water are acting as your hot water loop. When cold water is needed, turn on your faucet and wait for the hot to flush out. The circulating pump also has a timer, so you can set pump for peak use time.

What you want is a tank less hot water heater. These are expensive to say the least. I cannot think of anything else that would meet your requirements to date.
