Hot Water Fix

I just ran across this water circulator. It is a bit price but it works.
An AC receptacle is required under the sink.

Just a month ago, I got one new in the box,at a auction. I paid less than a dollar for it, retailed at over $300.00, but I gave it away, not thinking of using it for avoiding water freeze up.
 
I led a sheltered life and didn't know something like this existed until AFTER I ran new water lines in the house and covered them up. Doing some headscratching on how to incorporate one now. Don't know if they save any energy, just gives you almost instant hot water. With just two of us in the house, I'd put it on a timer so it would only circulate in the morning and a little in the evening.
Thinking about one for the barn water to circulate every hour or so to avoid freezing.

is this for one of those under the sink instant water heaters? cant see how it would work for a convential water heater way down in your basement . bill m.
 
A good idea in some applications along with super insulated pipes.
One of these days I'm going to install those 1 gallon under the counter 120V water heaters in the bathrooms and kitchen.
 
Hello bill mart,
I did not realize that the printing maybe to small to read. It is a circulator that when installed at the furthest point away from the hot water heater, will circulate and mix the cold water into the hot water. It then makes the hot water available as soon as you open the hot water side of your faucet or the shower.
Its not new, I never had a good picture and the operation of the unit before.

Hello Dave2,
The unit has a thermostat that moves the cold water into the hot water tank into the cold water supply and back to the water heater.
No timer required its a stand alone unit, unless you want it only to work for a certain period. That would defeit it purpouse to make hot water available as soon as you open any the water valve.

Not necessarily.. No since having it available 24/7 when you only need it a couple hours a day.

every need is different.

Used to be common here but not so much anymore. They throw them at you in the big box stores to replace units where they are still used. Kind of a money pit though. They suck up electricity like when you hit the bottom of a milkshake and you need a different type faucet (at least the ones here). A circulation pump would be money much better spent if you already have a hot water heater. If your pipes aren't insulated, a timer set to work just at times needed will help save some bucks..

I have the same unit except the thermostatic valve is separate from the pump. The pump is mounted anywhere in the line and the valve (no electricity) is at the farthest point. It bleeds cooled hot water into the cold line in effect returning it to the water heater. Pump has a built in timer and consumes 25 watts.

Making the large main line short and smaller branch line long saves more fuel.
 
Hi Guido,

I just read an article on curing this very problem. I have no idea if it works but it sounds reasonable.

"T" off the hot water line for the faucet supply using the center tap of the "T". From that "T" end, loop back into the main HW line a couple feet away using another "T".

What this does is cause the water to thermal siphon with in the pipe loop, cold water on the bottom and hot water on the top. They say it would do this all the way back too the storage tank without having to run a return line.

Try at your own risk, as I don't believe every thing I read.

Hello T_Bone,
I'm with you about not believing all that you read. The last place i worked, the owner had this type of pump put in at his house and told me it worked good for him. I have not seen him since 1999, so i can't attest the longevity of the system.

I replumbed my house with a third pipe to do the recirculation thing. Then I sat down and did the math for the cost of the once heated now cold water drawn through the pipe to bring hot water to the tap VS. the constant energy cost of keeping water heated in the pipes (the heated water itself, circ. pump power, etc). No contest. It much cheaper to waste a little water. You likely only use the hot water taps once or twice a day.

I also insulated every single inch of piping both hot and cold and when you draw hot water through until you get it, the waste water is not back to cold water temperature yet.

In the house I grew up in our heat and hot water came from a oil fired boiler. The plumbing had been arranged in a stack up through 3 floors of a split ranch with a thermo syphon return line from the topmost plumbing connections. Had instant hot water almost anywhere in the house. Never thought about the energy costs. Most kids don't.
 
i use this one, its an on-demand one, it only runs when you need it too, so really easy on electricity.
