Are your tankless water heaters appropriate for use with a solar system -- to boost the temperature of the water when there is not enough sun?

I am sure that it can be used as a back-up for the solar. It will probably need some kind of diverter for the water so the water will not go through the heater when the solar is OK. Sort of like a thermostat that will open when it is needed and close when it is not. However, I do not think that this type of water heater is appropriate for that function.

Yes. It uses minimal energy. However, there is a plug in adapter on the market that some dairy farmers use that wont power devices unless the temp is 35F or below. I cant bother. The one disadvantage to plastic vs metal lined heated dishes is mold build uo. You must scrub dish out once or twice a week. Which you should do anyway for shared water sources. :))

Assuming you are using the EMT2.5 as a booster, as long as the water on the supply side is lower than the maximum setting on the thermostat, then it would in fact boost the temperature. Otherwise it would just be a holding tank and maintain the heat there.

Your much better of with the heater that you have. a tankless water heater may require 120 AC to run. The suburban runs with out any ac or dc power....

Not at all, but this means you might not be getting enough juice to the unit. You need a 200 Amp panel, two heavy cables (6/2 and 6/3) running from the unit to the electric panel. And you need to have 2 upgraded breakers at the panel. Also, if you have a lot of electrical usage at any one time (dishwasher running, A/C cranking, TV, and all the lights on), this may strain the system a bit for the short time that you use hot water. And, it also depends on the model that you bought and if that model accommodates the house size and family that you have. I have not had any issues with this unit so far. Then again I live in FL and I never need the water to be all that hot. I keep the temperature setting at 117 degrees and that seems just right. However, I do need to install a descaling system to prevent any scale buildup inside the unit, because FL water is hard water. All part of my master plan. ;O)

It is completely safe in the sense that it cannot get hot enough to damage or melt plastic. It may still make the water too warm however, it all depends on the ambient (room) temperature. This has no thermostat, it simply emits 5 watts worth of heat all the time. You would need to try it with a thermometer, and be aware if the room gets warmer so will the water. All the parameters in only a half gallon of water will fluctuate rapidly and are difficult to control- if this is for livestock and you can get something larger you will find it much easier and much better for the inhabitants.

We have a 10,000 gallon above ground pool and we live in WA. state where our summer's see sunshine about 65 percent of the time. We have 2 solar heaters and found that they raised the temp. about 7 degrees. You will have better insulation since yours in an in ground pool, but I don't know what to tell you for sure...Good luck!

No, you only have to add that if you want to extend the chlorine life. We haven't had to, but we have limited amount of sun on the water each day.

Hi, I can't say for sure as I have she Noritz, but I have a water softener. I do know there are many recommendations that if you have hard water something should be done to prevent build up.I assume you're considering a tankless as a move away from a tank style water heater. If your tank style did not last many years I'd suggest something to protect the tankless. This of this. These units run water through small tubes that are heated to make hot water. These tubes wouldn't take much to be come clogged. Hope I was of some help.

Yes you can, I've used water and the heater,runit for 2 cycles and they come out great.

It won't make water higher than 120. So < 120 is a good attempt to answer your question. If you are pre heating with solar, you prob. are limited to around that temp.

No, put if you have plastic a cup and did a hole on near the beach you can build a solar still. Take and dig a hole cover it with plastic, place a weight over the collector and wait, several can keep one or two people a live with safe water. Use a rock or stick to put the low point over the collector It takes a few hours to a day to get a quart or two and you will need a gallon to 2 gallons a day person.

Check your local codes. If you can use PVC for a regular water heater you can use it for a tank less system.

Sure, you can leave the solar cover on. It will still add some heat into the water but the better use is that it will keep debris out of the pool. Even if the pool is not used during the winter season.

Be sure your pump is running when the sun is blazing; else, you can boil the water and/or melt ANY solar heater. But if your pump's running when the sun's down, then you'll be cooling your pool. Have these mechanics in order BEFORE installing a solar heater!

I would guess yes, I think it would heat the water. However, I'm also guessing it wouldn't work as well because of the loss of effiency since the sun is shining through a glass window before it hits the reflectors. Again, I think it would heat the water, it will just take longer. Hope this helps.

Tankless water heaters provide hot water at the point of use (e.g. tankless heater in bathroom vanity). I'm not sure what you're trying to accomplish. Although it would not be very efficient (heat loss through pipes) I suppose you could recirculate hot water from a tankless heater to another faucet . I would contact your tankless heater's manufacturer for specific limitations such as maximum inlet temperature.
