If the unit loses electrical power, and it is currently producing hot water, does it immediately stop, or does it keep working until the demand stops?

I am not a technician, and I actually chose not to invest in the Takagi, however, you ask an important question. Unless the unit has some kind of backup system that kicks in, when the power fails, then it won't be able to produce hot water on demand, and the unit would immediately shut off. When power returns, be thankful, re-boot and you're good to go!

Yes, it will stop in short time, usually when the water starts to get hot. It will happen every time you turn it on. It is normal!

It shuts off when it begins to boil. (And it doesn't turn on again unless you restart it.) LOVE it.

It will shut off when water runs all the way out. If yours does not shut off you may have a problem.

if the water flow isn't fast enough the water will get too hot and will shut off for safety reasons and once it shuts off it doesn't like to turn on for a while. because of this i run the bathroom faucet at the same time and adjust the flow to play with the temperature and keep it stable. i've never had an issue with a drop in water pressure turning it off and we use multiple faucets with it running like flushing the toilet running the washer and taking a shower and not had a problem.

My unit has not over heated. If its really hot, I would think it is a defective unit.

You can just let the water run and you will get hot water just as if the pump is not there. Also, you can turn on the pump with the built in switch. Mine is in a location such that it is not easy to get to. If we are going to be away for a week or more I will make the effort to shut the pump off.

Power goes out- the water flow/siphon/filter operation ceases. It resumes once the power is back on again. Hope this helps- works just like any regular filter - or was there something specific in its design that prompted your concern?

Mine does not shut off either even when the water is too hot. I would return it but I had discarded the box already.

No this water heater needs to be plugged into an outlet to work, so if the power is out then its useless. If you are looking for one that might work in a power outage try the bosch line. I had an older model bosch that didn't require electricity to operate.

If not flowing any water for a long period of time the lamp will heat the standing water in the unit. I consider this normal.

I only turn is on when I sit on it (there is an on/off button on the side). One min or two is sufficient to get the water warm, and I do not even care if the seat is warm or not. I do not see any impact to the electricity bill: if you are still concerned, you probably need to consider hard switch all appliances off around the house.

Yes and if you turn it back on without adding more water it will shut right off

this unit does stop working when the water runs out and a digital display will let you know it is out of water. Hope this helps. I have to say I love this unit and works outstanding. Joseph

I haven't noticed any changes in my electricity bill that could be attributed to this instant hot water system. While it works much like a conventional house electric hot water heater, it is only heating 2/3 of a gallon, not 30 or more gallons. It is under my kitchen sink and you can hear it cycle, much like a refrigerator does, to maintain the temperature. So, it is not really heating all the time, just as needed.

Yes, it restarts after a minute or two pause if the power is interrupted. I think the pause is to reset the condenser, like what a refrigerator has. Those are somewhat touchy in power outages.

No there is a flow valve that starts it. this unit is not worth the money. You have to turn the hot water all the way on to get it to start and if you turn it down it turns it off. The company is no help with repairs or replacement Buy from another company
