I plan to feed warm water to it (using a portable outdoor tankless heater), will this be a problem?

i fill mine with fresh water and run a pond pump to circulate the water,it will warm in the sun no problem and saves on water,just put the pump in the pool area ,its safe ,just put in to a GFI,works great here on the north shore of new york

We live in WA state & the tap water is COLD. We hooked it up to the hot/cold faucet in the garage sink & used warm water. No problems!

I would say it shouldn't be a problem as long as the temperature is set to a reasonable setting.

No. You will need to keep an eye on the temperature of the water. It is better to buy a preset heater for the tank or use the timer.

Should not be a problem unless it gets wet. Make sure your irrigation is turned off. Load your unit with some dry dog food.

It shouldn't be a problem, as long as you flush the water heater with vinegar once a year. This is regular maintenance regardless of how hard the water is. You can find a decent circulation pump for around $50 on Amazon, and tutorials on how to do this on YouTube. Hard water shouldn't stop you from buying this heater...has been working flawlessly for us for more than two years!

Sure, but you'll be operating it at capacity and that might lower the life expectancy of the heater. I used two to reduce the load on just one big one and if one does go out, the other can carry the load until I get a new one. My tank is a marine tank, it might not be as big a deal for fresh water. Hope that helped.

This unit heats the water to several selectable temperatures, so no need to provide hot water to them. Matter of fact, I recall the owner's manual cautions one NOT to supply hot water - only cold water.

No. Get a 50 gal plastic tank and an a water heater. Otherwise start digging and running underground water lines and power....good luck.

Hi, unfortunately probably not. Your existing water heater likely uses PVC venting and this tankless will melt it during exhaust. If you have a relatively short, straight length then it won't be too expensive to vent. But you NEED stainless steel venting rated for this. While i'm at it, you may not have the right LP line either. check your line, if it's less than 3/4" you will need to replace it. I had 1/2" LP line and PVC venting. I ended up going cheap 50 gal electric. Was way to expensive to replace everything for me

Yes, it should be fine buried under the gravel provided you have a thermometer, which you really must have no matter where you place it. Heat rises, so placing it on the bottom probably is the most efficient, meaning it will get the tank as warm as is possible. If it is too warm, raise the heater up nearer the surface and increase or add some water movement. If it's still too warm, you need to put it on a timer, an external thermostat, or purchase a lower wattage heater. The 'water line' indicated on this heater is to insure it is well submerged, not to indicate that any part needs to be above the water. The heater is 100% submersible, it can and should be completely underwater.

I think it will heat it well, but I am not sure how long the tank will last. Could get expensive. Do you have electricity in the shed?

Unsure. I wouldn't leave it unattended--unsure of what would happen once all the water boils 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.

you would have to use a drop in heater - because it hangs, and is plastic, you can't use a metal heater (that a metal waterer would set on).

Sure, just leave the hot disconnected or off. I have mine in an outdoor kitchen

The attic is not considered outdoors. Your water heater in the attic most likely has a vent pipe. To mount a tankless heaters indoors you would have to use double stainless ducting. More importantly you probably do not have a 3/4" or larger gas line at your your existing tank. The sizing of the gas line is critical to make the tankless work. Outdoors you can mount it near your gas meter and will need no ducting. You will also need a 120V circuit for the fan for the tankless. Takagi tankless heaters are the best! No problems when installed correctly.

I can not image what concerns there would be. We use ours Monday thru Friday so it is only off for the few days, even 4 or 5 days at Christmas and Thanksgiving and we have had no issues at all. The water is heating all the time, well on and off and on and off, so that the water is always warm and ready for a new pot. There is a cover over the water reservoir to prevent evaporation so I think that would not be a problem.

Yes, you may. Just move your settings from timer to "on" position. Remenber this is a small pump, you can't have hot water right away.
