Hello During cleaning do you leave panel on or off? This Eco Smart 27 KW electric DHW panel requires 3 - 40 breakers in the electric panel. It has 3 heating elements that we’re getting dirty with some scale build up. Therefore the hot water did not seem to be as piping hot as it should. Therefore I switched to the oil boiler for DHW with the 40 gallon superstore tank while acquiring some parts and knowledge to possible clean this thing! LOL The Webstone tankless water heater service kit was the first one I came across at the big plumbing house but Home Depot actually has a very good price on it. https://www.homedepot.com/p/Webston...ll-Port-Brass-Ball-Valves-42443WPRR/323227498 My issue with this kit is that the On Demand panel is mounted tight against the wall so no room to turn it around to fasten the Valves to the panel. There are what is called Spud Meter Connectors for $15 each to make this job easier but adds to the cost, Then I found the HQMPC tankless water heater isolation valves kit. This has what they call a union but looks more like the spud meter connectors built in. However it comes with an adapter which has a nicely engineered wider flange for a better and easy connection to the On Demand panel. So then I got 2 nipples with a nut for a wrench in the middle at Lowe’s for the bottom valve connection. Proline Series 3/4-in x 3/4-in Threaded Male Adapter Nipple Fitting in the Brass Fittings department at Lowes.com Just to make it a little quicker and easier, I got 2 - 3/4 shark bite Pex connectors instead of reusing the Pex connectors there after cutting the pex piping shorter to include the valves. All the threaded pipe connections were more easily done with the 1/2” wide Blue Monster Teflon Tape. I cut the tape to approx 20” for 5 wraps to make a nice water tight connection. The Blue Monster is the easiest pipe wrap to use! https://www.homedepot.com/p/Blue-Monster-1-2-in-x-1429-in-PTFE-Thread-Seal-Tape-70885/306136345 All this work went like clock work with a channel lock pliers and an adjustable crescent wrench and when it was time to run the cleaner it was super easy! The Whitman Flow Aid System Descaler kit did the trick. The cleaner is non toxic and works 20x better than vinegar. Therefore the cleaner only has to be run through the panel for 30 mins. Amazon.com: Whitlam KITC FLOW-KIT, 15 x 10 x 15, Black : Everything Else Just hook up the hoses to the valves and pump and put in a gallon of water with the quart of cleaner in the bucket that comes with this kit. Run the cleaner for 1/2 hour and then turn on the cold water to flush the rest of the cleaner out. Remove the hoses and turn the valves back to normal operation and bingo it is done! Good DHW On Demand for another year! Anyone else do this? Was the water hotter when done? How often do you flush it out? The scale that is cleaned off is usually white calcium carbonate so you may not see real dirty water when done. You will notice hotter water and maybe better water pressure too. So far after a day the water is nice and hot!

Nice video on testing and replacing a bad heating element! Also if the Eco Smart is not putting out any heat which means 240 VAC to the elements. 1. Check the glass fuse near the temperature readout. 2. Check and replace the flow switch. 1. Fuse Replacement Video 2. Flow Switch replacement video!
I also have a SuperStor tank. Did anyone try this Hot Water tank cleaning tool? The Amazon reviews on it are very very good! See video here on using it.
Hello I just did the nominal tank maintenance by just opening the bottom drain and draining the bottom sludge into a bucket outside. The new expandable hose is perfect for this job. There was some black bits and rusty water! See pics below. An annual 1/2 hour On Demand panel flush & the 15 minute tank flush each year should really prolong the life of these utilities.
