Caleffi products are just so well thought out. You were abel to balance the system in minuets even thought the loop information is unknow. What a great product!
I’d be really interested in smart plug features that could tap into room sensor data so the pump runs for whatever amount of time when occupants enter a bathroom/kitchen. Great fix for this system, dude!
- Your specifying the components is valuable information, but I have a question in that the head of the pump is 13', so I would guess that the loop needs to remain well below that? - I would think that unless someone is doing a gravity system, it would be much cleaner to have the returns dump into the cold water line above the water heater? *I didn't realize until this video that I would need a balancing mechanism. Thank you for taking the time to make this video.
People, if you want warm water coming out fast at the faucet, simply make the loop without installing the pump. Pump is not necessary at all. Once the full loop is made in the warm water line, warm water will circulate through the warm water pipe by convection effect where hot water expands in the heater and forces the water to move through the loop to colder region and back into the heater and continue the cycle. I had a water pump installed but failed and I took it out and bypassed it and I still get nice hot water very quickly better than ever before with no headache to deal with failing pump or timer. Pump and timer are expensive and difficult to maintain and absolutely not needed in most residential use. If you do not believe me, try first before you take the trouble of installing one.
Well that would be true if you installed a dedicated loop sloped properly all the way from the heater to the farthest point and had no branches on the main trunk line. Most homes have multiple levels and split branches on the main, a gravity circulating system does not work for that at all. This is basic stuff, any plumber would know that.
@@mechanical-hub My home is a big two story house (3500 sf) with 3 1/2 baths with faucets located all over the place and I get warm water very quickly everywhere including kitchen, believe it or not. The home came with a pump installed but failed. So, I replaced it with another one and it failed again quickly. So I took out and bypassed it and I am getting the warm water as quickly as before even in cold winter weather. I am sure my house, due to its size, has multiple levels and split branches with faucets located very far from each other but I have no problem at all. I guess, depending on the pipe routing, it may not work for some homes but I would think it would work for most average homes.
@@tommason4702 you got lucky. The water heater is sending hot water to the high point in your loop first. Any other pattern won't work for a gravity fed loop.
You’re videos are always really informative! This is a great way to set up recirc. If the supply lines are 3/4. Can the recirc lines be 1/2? Seems like that would work.
@@MyGoogleRUclips no. But after more research I decided to go with 3/4 my setup is a little different because I have all fixtures coming off of one big loop. But I think if you are running the line back from the furthest fixture only then 1/2 would suffice. I’m not a pro tho. Just a professional homeowner!
Interesting setup, but I'd never want a pump that runs 30 mins every hour, especially mid day or while everyone is sleeping. The "learn" feature would have to be pretty smart to gauge the usage gaps, and we don't wash dishes or even take showers on regimented schedules.
I read, from a RUclips comment, that an expansion tank is required when you have a dedicated recirc line. Where would that be installed exactly? On the cold inlet to the water heater before the spring check valve? Or somewhere on the dedicated recirc line?
my question is, are you taking your hot water from the hot out tube side and returning it to the drain port thereby introducing the recirc water to the bottom of the tank, and if so is there a down side to doing it that way, ie damage to the drain valve and interior piping of the water heater, great video content
There are 2 ways to pipe your recirc line. You can either spin off your boiler drain and pipe your resirc into the bottom off the tank like he did in the video. Or you can pipe your resirc into the cold water supply line entering the water heater. If you run your pipe like this, an additional check valve is required to prevent hot water from entering your cold water system. Both are acceptable ways to pipe a water heater. When I lived in Minnesota, pretty much every plumber I knew piped their resirc to the bottom of the heater. Now I live in Tennessee and every plumber here pipes the resirc into the cold water supply. I guess both are fine, it just depends on who taught you plumbing. I do both depending on which way is going to be easier for the job I’m working on.
Question,, did you turn the face of the pump somehow, I just received the same pump and if I install the pump exactly the way yours is my water flow would be going towards the pressure valves and you show your pressure valves water flow going towards the pump,,, so is there a way to turn the dial face of the pump so the writing on the pump is upright like in your video,,, I assuming the water flow should all be going towards the bottom of the water heater,, Thanks for any help

Nice work bro 👌

not a code violation by screwing into the tank shell?
Didn't even know about those Caleffi line balancers. Very important in that situation, but how much do they cost? Couldn't find a price online.
Wow, such a great idea with the pump, but $350 !!?
u need more then 10k subs good info im goin 2 start tellen guys and gilrs in plumbing trade tune in 2 u bro master plumber jim here in mpld thanks
GOOD MORNING PLUMBER
Tis a little thing, but it would be easier to think of you as a Pro, if you pronounced 'potable' correctly.
What an idiotic comment. It'd be better if you just kept to yourself. lol
