Live in California. To avoid water loss, we have a circulating pump. Possible to have a circulating pump on a tankless water heater

I don't know, but the idea of a tankless is to have hot water on demand and not have to keep it heated. Since it's electric you would be using it all the time. I think this would be very expensive since it uses quite a bit of electricity (I think mine has about 6 fuses). Also, they are more "fragile" than a regular water heater; they don't hold up well with considerable use due to scaling and other circumstances. I wouldn't advise it.

Continually circulating water through this unit is definitely not advised - it will burn out the elements as this is an on-demand unit. There is a circulating pump out there called a waterquick circulating pump, which bypasses the pressure vessels inside the unit. Even then, I would be careful and check the warranty carefully to make sure you are covered if this unit is put in a circulating system.

It's just like using a standard water heater in that regard. You set the water heater to the temperature you want. If the water is too hot or too cold, you adjust the setting on the tank. All the pump does is circulate the water heated by the tank.

No. Domestic hot water systems are not like hot water heating systems in that they are open loop systems. Pressure is determined by the water supply, not by a recirculating pump, hence do not require an expansion tank to handle pressure surges.

E, I am in Massachusetts where freezing is plentiful in the winter. I have float type pumps on our gas furnace and air conditioner. I bought and installed this pump on my portable dehumidifier in the basement, to save me from hauling the water-filled container up stairs and outside every day in our humid summers+. This pump's action is triggered by the float in the reservoir. I ran the (included) tubing up overhead and down to the liquid drain pipe for the washing machine. Been working like a charm, saving my 75 year old legs and back... Go for it.Jim B, Cape Cod

Yes with no problem as long as the water in the pipes are not frozen. The only issue. With most all tankless heaters is that will only blend watering you have two control vales as in one foe cold and one for hot. They will network on a single control bled faucet.

yes - however you are limited to the volume of water being consumed vs capacity of heater

Yeah, these units are made for family usage, so you can do that and/or run hot water in the kitchen at the same time. Take a look on their site for a chart of these tankless water heaters to see which one best matches your family size and household.

The only issue I have found with the tankless water heaters, is without soft water the heating coils get a mineral build up. Otherwise, when maintenance is required the tankless heaters are much lighter to carry out and much less messy.

Yes, there is a panel in the heater where you can adjust the temperature to your needs. If your house is big, install a recirculating motor which will give you hot water instantly. You may disable the motor when hot water is not needed.

ABSOLUTELY. I live in Colorado and right now my incoming water is below that (sometimes in the 30's) and it works fine. Now, It will have a difficult time running 2 things like a shower and a sink at that temp but with 1.75gpm you will be set. I've had mine for about a year and love it. This is the 4th tankless water heater I've had and couldn't be happier, it works flawlessly.

Yes but what's the advantage? You would only be keeping the recirculation loop hot. ...same as on a tank. .. if your instant heater is far from the tap/sink I suppose it would work Just as well. If you insulate the pipes good the heater won't cycle as much and you won't be heading your walls/floorboards.

I think the guy in Los Vegas is full of it. If not they waste a lot of water that California would pay dearly for. Ours (mid Kansas) is 1.91 per 1000 gallons. That is 16 time more expensive than he is stating and that equates to 3600 gallons of wasted water per month unless it actually does shut off the flow when the tank is full. I see no mechanism that would do that unless there is a high pressure shutoff somewhere.

Yes you can I am assuming that your water lines are cpvc and have the appropriate heat rating. You can find the rating printed on the pipe itself. The water heater will only heat to 140. You can bump that to 160 but need to install the commercial controller. Hope this helps.

You jut need one, which goes on to the cold water flow pipe into the tankless water heater.

It works fine without a tank, but a tank helps to ballast the system, so it depends upon what you want to do with it, or how many CFM you need per unit time.

It is not an inline heater. No tank type water heater is designed for that application. Check tank-less heaters, they will give you a solid 20 degree rise, on average, with low levels of consumption.

I live in Michigan I just set a floating heater in my pond in front of it and had no problem left my pump running
