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.
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!
@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.
@GPE001 How do you control a gravity fed circulation system so that water is not circulating 24/7 even when people are sleeping? Isn't this the most energy wasting solution of all?
@utube4greenfuture By installing super insulation on the entire piping system EXCEPT for the last 20 feet. You are going to lose some energy. Maybe a few pennies a day. This is the price you pay to have instant hot water. You NEVER get something for nothing.
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.
@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.
@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.
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.
If the bypass valve closes at 95 degrees, what prevents water from siphoning into the cold water line when this valve is open and you only want to use cold water? The last thing I want between my hot and cold water lines is a normally open thermostatic valve allowing cooled down water in my hot water line to siphon over into my cold line everytime I flush my toilet because hot water wasn't present in the line to keep this valve closed.
this system has problems . i have one . the kitchen sink where the bypass valve is installed . warm water comes out of the cold water side when the pump is on . there is no way to fix it . i had a plumber look at and he unpluged the pump that was his answer . and i am better off . i no longer have hot water going into my ro system . i think homeowners should think twice about this before installing it .
You probably have a defective sensor near the pump that's causing the pump to operate all the time. Go to the Grundfos website and watch the animation showing exactly how the system is supposed to operate. I'm convinced there is a problem, but it's not that the entire system is flawed.
2 do this you do not need any brand ( grundfos, willo, etc) , just instal a programable electrical switch ( can be find eith the socket connection for the waa outlet ) , and program it for your needs . Save the extra cash for soap :-)
If I understand this video, the pump takes water out of the hot water reservoir and pumps it into the cold water line?
I have seen a pump set up near the point-of-use. It had a separate return pipe to the hot water reserve. All the pipe was wrapped with insulation to keep from pumping the heat out of the reserve also.
I must be cornfused. How do you get hot water up the pipes when they are already full of water that has cooled off? Are the hot water pipes actually empty until I turn the faucet?
On a normal system the the line coming from the water heater goes in and branches many times, finally ending at the furthest fixture. On a system set up for a recirculating pump, the hot line does not end at the furthest fixture, instead it then loops back to the water heater where there is a recirc pump installed. So this pump keeps the loop full of hot water allowing quick access to hot water from anywhere in the house. Some pumps have timers on them, so they are not constantly spinning.
Strange I should find this very same article already developed.Where this heating application comes into play, it will serve the same issue and allocate hot water that is immediately available without loss of water. I use solar power for my hot water system but even through using solar,it doesn't save the vast quantities of water that is wasted at a high financial cost to me as a consumer. I will gladly look at investing in one of these beauties within the next year. "Well done".
The Tankless water heater is new and was tested in the factory where I bought it from and was working fine. It is installed in a concrete brick home with 1/2 CPVC tubing which the tubing is installed inside the concrete sides of the house and lead up to our bathrooms. What is happening is the pressure of the water is fine and while your taking a shower (Located on second floor of the house)
Would a pump like this work to boost the hot water heater from a tankless water heater I have. I am having problems with the hot water cutting out while I am taking a shower, it will cut from warm to cold!
It sounds like you might have a defective dip tube. Go read all about that at my website. And tell me how in the world you could possibly run out of hot water if you have a tankless heater? That should never happen unless it is broken, undersized or the incoming water is super-chilled. You might want to read my Tankless Water Heater column as well.
bigjohnnywad. it sounds like you have a siemens water heater or similar. chances are you have your water temp turned to max.. you're better to turn the water temp down abit. this will allow for a buffer in the computer programing and it will stop pulsing between cold and hot because by law in many countries the maximum allowable temperature is the max on these heaters. so when it reaches this temp "it hits the wall" and and there is no room for margin. so it then turns off and then back on.
I'm sorry, I don't have a clue what you are talking about. This video is about using an existing water heater and a cool pump that has a timer. At preset times, the pump turns on and gets hot water up to all the fixtures in a home. The pump can go on and off many different times of the day so as not to waste energy.
This made me think of another idea I had in the past. Would it be possible to do some kind of modified plumbling into a radiator, made for heating homes, so household hot water would circulate through it to help heat a home?
I have one other question, unrelated to this. Is there some kind of limiting valve for a toilet water intake, so if it took more than two gallons to fill a toilet tank, it would automatically turn off the water to the toilet tank?
There are boilers that do double duty. They have been around for years. Toilet ballcocks have adjustments to limit how much water goes into the tank. Trouble is, older toilets may not function well if you only partially fill the tank. READ all of my past columns about low-flush toilets, and the problems the first-generation ones had years ago. It is high-school physics: F=M x A
Not sure about the states but here in the Uk you can have silent fill valves for toilets which will limit the flow speed and quantity of water that the cistern takes, limiting noise when flushing and limiting water consumption
