Is this model suitable for recirculation?

As per the instruction manual it is. You can go to the Rinnai web site and download the manual.

A small one without a lot of gpm, yes. But you would need to figure out the waterfall attachment, you could probably purchase an off the shelf one to fit.

I think this will be too small for your purposes. I would look for something that has 4 gal per minute flow. Our is primarily used for a workroom in the garage.

I doubt it... it would all depend on the volume and rate of flow. I think measurement would be in order if I were to try to trust this method of microorganism control.

Probably not good for it - that CO2 wants to go somewhere. You could put a T-valve on the line to cut off the supply to the tank and redirect it to outside the tank. It functions just like a very low-power air bubbler.

I have a 60 gallon and from what I have seen as long as you can maintain 80psi you should be fine. Hope this helps.

Sure. Passing water through the media at moderate flow rates would work fine.

That would depend on the desired result. I added a shut off valve for the air and operate typically @ 35psi.

No, it would not do that. It can smooth out pressure pulses over very short periods of time. 10-20 seconds typically. Most gravity fed systems don't have enough pressure to make an accumulator work well. This should be used on pump systems of 40-60 psi.

I found it to be less than satisfactory in regards to heating water for much of anything... I ended up using it as a Point of Use booster on a existing hotwater line after Plumbing a hotwater line to the point where. I had purchased this unit for originally. I hope that gives you enough info to come to a conclusion.

I am using mine in Southern California and love it, but do not know if it would work well in colder climes. It is an outdoor unit, so I doubt it, but don't know. I believe it would work with a recirculating pump, and may put one on mine. Troy.

I have used one placed in a small aquarium for over a year, to recirculate water to a small hydroponic garden.

This is just fine for that. There is a model up that gives you some fancy lights and an option or two but now worth the close to 100 dollars more. Plus you don't want to be dumping more than 2 minutes of water at a time on top off. This is residing in a sump chamber so it should only run a few seconds.

This unit has the capacity you would need. The nice thing is your hot water is constant. You can run pretty much what you want at anytime, better than the 100 gal. high recovery water heater I was using. You just need to run you water a little longer the further away from the unit that the faucet is located. Note: for laundry use I will run the hot water in a nearby sink before I start the washer. Minor inconvenience. I am impressed with the unit and happy that I made the change. Has been cheaper, also. Good luck!

I don't recommend our public use model for your situation. Any 1.5 gpm model found in our home/hotel section will work best.

I have heard of outstanding result from people placing it on the recirculation line of the boilers.

I love this thing. Works great for me. If there is a lot of airflow, it could be possible. Likewise, there would need to be a steady supply of CO2 coming from some type of contraption.Normal CO2 levels hover around 350ppm to 450ppm. To give you an idea of the danger zone, the CO2 Monitor would have to read 5000+ppm for you to be in danger. The CO2 Monitor only measures up to 2800ppm approx and then reads "hi" or "max" or something.Hope this helps.
