ECN Forum Forums General Topics of the Trade General Discussion Area Insta Hot voltage

I am installing some "Insta Hot"s and needed to know the voltage and amps.

You need to contact the Mfg. or distributor for that information. If its residential
the voltage could be 120 or 240 volts.

Usually your looking at 120 volt and about 10 amps, but you should check the rating on the unit in question.

Mr. Eagle,
Thank you for the basis. That is the problem. All I have is a set of plans and they just say "Insta Hot". I am running 12-2 MC cable.
There will be three of these on one circuit but I doubt if they would all be on at once. Or would they? This is for classrooms for a Sunday school.
I don't know the manufacturer and Google didn't help although it works good for crossword puzzles and Acrostics.

In most cases 1 - 12/2 per unit will get you coverd @ 120V or 240V. I would not gang them together.

"would all be on at once. Or would they?"
First start up, and every power outage or lunch time.

Heres some...

The right manufacturer would be a better bet. But you'd be save to figure 120V @ 750~1800W

You really need to get the specs on these units. I think most of the replies here are referring to the insta hot units that get installed at the kitchen sink to provide hot water for tea, etc. These units have a small tank that holds the very hot water they don’t actually heat the water instantly. If you use more than a half gallon or so of water then you will be out of hot water until the water in the tank has time to reheat. I think the units you working with are designed to instantly heat water for the faucet. They typically are 2.4 – 5.5 KW for a single sink.

Good point!

What this sounds like is an Electrode Boiler system.
Not unlike our "Push-through" systems here.
I'd go along with caselec with regard to the power rating, they aren't small by any means.

Simple answer for this. Customer must get specs or units don't get wired.
