Todays shop time.

Since the water tank is hot and directly under the faucet it only has to travel a couple feet or so of flex braided supply line. Since my faucet is tall and the hose head is retractable it has a little longer to go than a typical sink hook up. You might cut a second off your time if you had a shorter run. :laughing:

Notice the T on the cold side. This is where the cold supply line gets split for hot and cold water. Don't do what I almost did and hook up the supply to the pressure relieve valve thinking the red and blue are your hot and cold outlets to your faucet.

What is the temperature rise on that 120 volt unit under continuous flow?
If you open the faucet up full do you see a decrease in temperature after a few minutes?
Thanks

So .. it keeps 4 gallons heated all the time? If it's off, any idea how long to get to temperature? I probably wouldn't want to run it constantly .. in our O/D kitchen.

Yes, keeps the water heated. Not exactly how long it took when I first turned it on but I'm guessing I checked in about an hour after plugging it in and I had hot water. I'm hoping since it is rated at 98% efficiency and only being 4gal, the energy use/cost is minimal. I plan to get a kill-a-watt device and do some measuring.

Still need to put it through its paces and do some measurements being the geek I am but looking at the specs...
1440watts (120v @12amp)
Recovery Rate @ 90ｰF Rise = 6.8gph
Temp range = 65degF to 145degF

Okay decided to go out and do a crude test and learned I don't trust our dial temp (cooking) gauges in water. Switched to a cheap digital thermometer with probe and here are my crude findings...

Temp set (measured... no indicator on unit) = 135degF

Note: unit set in between 'ideal' and 'max' settings.

Cold water supply measured at 52degF

Filling a 5gal bucket... and after about running a little more than 2gal the temp started dropping. At roughly 3gal, temp of running water dropped to 125degF. Stopped there. Now very glad I got the 4gal vs. 2.5gal tank size for about $20 more. I don't figure I will need much more than a 2/3 bucket of hot water at a time but now curious as to actual recovery so timing that now.

Okay I missed the heating light turning off but it was less than 15min for it to recover. Maybe 10 or so?

Thanks! Good information.

Here's the power meter I have. There are cheaper ones available but, this one gives you lots of information.

Ha... funny as I just ordered this exact one on Amazon this earlier today! I've never used anything but a multimeter before so looking forward to this tool for measuring electricity usage of various tools/appliances especially my new mini water heater. Want to know if I should be leaving it on all of the time or maybe on a timer?

Just hook it up .. when you want to monitor a value.

No, I mean I want to learn if I should leave the water heater on all of the time or on a timer based on energy usage.

Pieced together two pieces of scrap from the black ribbed thin vinyl floor runner I used for the countertop and put it down on the cabinet base to finish it off. Trying to decide if I should add a couple of swinging doors on the sink cabinet or keep the utilitarian look (which I kinda like) and save a few dollars on hardware?

Neat setup. My opinion would be add doors to minimize dust. Plus they'll look great seeing the rest of your creations do.

Came in the mail today... plugged it in. Suppose I should read the mini manual and see what I need to do to get this reporting out info! :laughing:

You'll .. do fine.

Ha ha... kidding. First observation is that when the water heater is running I am burning about 0.3kW per minute. I am paying just under $0.11/kW once I blow past the base rate of $0.09/kW. Only takes a couple minutes for it to recover during hand wash or small bucket fills. So maybe I'm spending 3 or so cents at a time unless I fill a big bucket. No clue yet on the kW used just for holding temp...

But once I allow this to run for a few days I will be able to report back some rough daily/monthly usage costs for a minimal use sink. If I haven't bored everyone at this point, I will report back further findings. I realize this is a thread dedicated to shop time, not my silly shop sink time! :laughing:
