Can this pump be used in a hot water tank recirculating line?

Has a C.I. housing. You may want brass. Don't think it is designed for pressures of domestic H.W. system. You would have to check the specs. I used it to replace a Taco pump on a forced H.W. heating system running at only around five lbs. pressure.

Yes - that's what I used mine for. I put it on a timer so it only runs during waking hours. My water pressure is slightly below 70 psi and there are no problems.

Yes. That's how our hot water system is set up in our house. The pump works great.

I used it to circulate water from a large boiler to a swimming pool and guest laundry

The answer is no. The pump comes on to pump water from the hot water line to the cold water line until the water in the hot water line reaches approximately 105 deg. At that point the pump shuts off, and the cross connect valve closes. If you are showering and the water starts getting cold it means that the hot water in your tank is running out and the pump cannot help that. The pump produces no heat and can do nothing about that.

Yes. As the connections are standard 110 AC, you can connect any brand (non variable) pumps.

To a point it will work. However, it will not remove all of the fluid from the pump because of the pump's design, nor will it remove the fluid from the lines or cooler. Maybe consider just getting a pan, loosening the return line, and drain all the fluid.

Recirculating pump attaches at the hot water heater and can be operated on a timer so it does not run constantly.Any faucet in the house will have hot water in 5 seconds or less.

Yes I think that will work fine. You can use it just to generate hot water. Hope this helps!

Sir, I live by the Grand Canyon. Everyone heare uses a shallow well pump. The water tanks are buried 34" in the ground for a rise of three feet to the pump and then the house. This is a shallow well system. It has no effect on your hot water. The flow rate, 4GPM is irrelevant. The pump has an internal pressure gauge to deliver approximately 40 GPM to your home

I used mine for an aquaponic system. I had the lines down 5 feet and it worked fine, you get a lot more heat when you choke it down with a manifold.

Check the flow rate on your tankless and recirc. Pump that will let you know if it will work.

Originally, I had a plumber installed a recirculating pump and hot water control valve. Unfortunately the valve was not installed in the farthest hot water faucet,so I bought this replacement Grundfos valve and installed it in the farthest HW faucet, I think? But it works.This valve should work as long as you have recirculating pump installed in your water heater.

No. just drain a little from the tank so when you disconnect the hot water line you won't have some water spill out.

as long as the pump is external to the tank and the pump produces enough pressure for your application

The manufacturer states it ca be used as a booster to the existing hot water supply. Hope this helps.

Sort of, but likely not really. I have two different water heating systems. works great with a tank system. My plumber contacted the manufacturer of my veisman tankless boiler/water heater and they strongly advised against using a recirc line and the pump. they said it would make the tankless unit run very often and likely short cycle, vs. a tank that cools a bit and then has to run a lot to reheat back to temp. I wouldn't do it on a tankless.

I'm sure it could be used with a sump pump. The 1-1/2' openings are smooth, not threaded. I used an epoxy to glue adaptive fittings for my particular application. My system only runs 35 psi max, so I'm nowhere close to redlining the valve.

I believe not. The pump must get its water from a water barrel or similar non-pressured water supply. Hooking to a hose would not work.

No, but as long as the pump is DC powered and it is no more than 0-24 volts (max rated controller voltage) you should be good
