Can these tankless units be used with a well? My water pressure is "all over the place."

Dear Kathryn,As long as the variation is within 20 PSI, you should be ok. Also do you have a backflow preventer installed. If not, please do. we do sell Backflow preventers as well so let us know if you want any recommendations.Also you should consult with a certified installer/professional in your region just to be on the safe side.David

This unit turns on based on water flow. It adjust the amount of heat from the burner based on the water flow that is passing through the unit. If I only turn on one tape the rate of burn is much lower than if I have three taps flowing.

I have no idea, I'd call Rheem Tech support. They were very helpful during my install. Personally, I don't think pressure variations would be an issue, but who am I to know?

This unit only requires a .4 GPM flow rate to ignite. Your water pressure has little to do with it, so it will likely work just fine. That said, if your water pressure is "all over the place", you may need a new pressure tank. It has a pressurized bladder in it that helps stabilize the water pressure as the pump turns on and off. I have a well, and the water heater works great, by the way. Good luck.

Presuming you have a pump that provides the minimum flow rate (gallons per minute) to turn on this Rheem tankless water heater, you should be fine. It will maintain a constant output temperature across a wide range of flow rates. The good news is that this unit turns on with a very low flow rate.

I have this pool and used well water, Never had a problem. Was just scared using 15000 gal. would be to much for my well

Should be able to,mine is installed as per picture,but as long as you have water pressure going thru the unit I see no reason it would not work

I have had no problem, I am using it on a water tank for my cows. The water comes from a well.

System needs between 20-30 psi to be effective. Most "normal" houses have a water pressure of 40psi or better, which is why this system comes with a regulator. A low pressure well should operate at or slightly above 30 psi, so it should work perfectly fine.

Yes, I'm sure that would work well. They are pretty dense pads so they might not flow a large volume of water through them easily. I tried to run all of my water through them in my sump and it backed up the flow.

I would opt for a larger tank such as this one so that your pump does not cycle as much. I use this tank for our whole house and like it very much -- no more water pressure surges when taking a shower etc. This said, suggest you find out about the capacity of your well - - a larger tank will require more water to fill and if your well has limited capacity, you could run your pump dry if you run out of water trying to fill the tank ...

No you can't. See product description " All functions work independently to ensure proper water pressure "

I believe you'll need to get "disposable tank regulators" as opposed to the large dual guage regulators you would use for a full size. eitherway, it has to have a regulator, or gas will release at tank pressure. talk about a bad day.

I don't know but I wouldn't even attempt. I am very handy and do a lot of work around the house myself, but the tankless water heater is way above my head. I had a professional plumber installed it, and he had a hard time. He had to call technical support a few times to finally get it to work. Good luck.

When new aprox 1G.P.M. on a max. well pressure of 60 PSI. I have 2 of these filters plummed in a series. These would not flow enough water to use as a whole house filter. I use them for drinking water only.

Check with your plumber or HVAC guy, but I doubt it. These on demand water heaters run pretty hot so need their own dedicated venting kit.

Yes, there is. I believe the box and instructions states this. These tanks work fine. I have three of them connected to my well with no problems.

I do not think that this valve will give you the required flow while hot water is not being used. It is designed to work in series with the Watts circulating pump and as such I do not think that it will have any effect in a tank-less hot water system.

No, the tank is not designed for in-line plumbed installation under pressure, per manufacturer's documentation. And I don't think the spigot fittings could handle the additional pressure, as there is already significant pressure from gravity on the large volume column of water. When the tank is full, the spigot pressure from gravity already feels like 60-80 psi or more. Not sure what that would do, hooked up to your household plumbing. Could potentially back-feed the public water supply if the pressure got low enough on the main line?

I am not using the pump in that type of configuration. Suggest you look at the specs to figure this out.

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.
