Maintaining a Tankless Water Heater

Tankless water heaters are great at saving energy. But, to maintain that energy efficiency, it is important to flush mineral deposits from the unit about once a year. This is easier and less costly than you might think, Matt Risinger of Risinger Homes (a High Performance Green Builder and Remodeler in Austin TX) shows us how.

I did it !!! It worked! I can’t believe what came out of there! Sheesh!
And that tiny little filter thing was FULL of stuff, too!
Thanks again, Matt – you’re still my hero, darlin’!
Is that heating all the water in that house?
WooHoo! I’ve never been called a “hero” before! Awesome, Thanks. Matt
Hey Matt in Austin! Thanks so much for making this video for us do-it-yourselfers!
You’re my hero!
I’ve seen a few eHow articles that reference my video’s. At least one of those articles was NOT right so please watch this video and consult your manufacturer on how to clean your unit. If you are unsure about how to do this I’d recommend paying a plumber to do this regularly.
Thanks for uploading this troubleshoot. As this information does not come by the manufacturing company. I’ve one installed at home from last 6 years, now it’s pipes are almost blocked and I was searching how to clean it. Thank again for this helpful video.
I spoke to a Rheem rep at a conference this year and he tells me your water heater is made in a Japanese factory along with another brand. The should all flush the same way. Do you see two hose connections under your unit? If not, you’ll need a plumber to hook up a flush kit. If you do have those connections the flush instructions are exactly the same. If you have trouble lookup the number for Rheem and call them for instructions. Hope that helps. -Matt Risinger
Hello. I have a Rheem RTG-74PVN-2. I looked the manual and I couldn’t find advice to flush the system for maintenance: only advice to clean the water filter and the air vent annually. Is there a difference between brands?
thanks
