The best investment you can make. In my application it had to be modified a bit, but it's pretty much a plug and play system for a standard chiller. Don't know why they call it a hot water heater? Don't you heat cold water to make hot water? Why do you park in the driveway and drive down the boulevard? In any case, back on topic. I have been able to install and clean scale in my Titan heater for over 5 years, the water coming out before and after has been amazing. I checked the water temperature before cleaning; 108F. After cleaning, the water temperature is now 120F. So yes, this thing increases heat and lowers electricity bills. If you have a tank heater, be sure to clean the bottom of the tank of mineral deposits, you may be surprised at how much junk/dirt there is. Sediment is deposited at the bottom of your tank. You can do this by turning off the power and draining the water from the tank by connecting a garden hose to the faucet at the bottom of the tank. After most of the water has drained, remove the access panel to the bottom heating element, then remove the heating element and of course, vacuum clean for wet/dry cleaning. I hope you have considered purchasing/ordering a replacement element in advance (since you have read this informative review) so that you can replace it before or after flushing the system. use to flush the system with vinegar, lime-a-way, or citric acid. Results may vary depending on water hardness and region you live in. After a few tries, you'll find what works best. By the way, always read the instructions for diluting the solution. Make sure you use protection. Eyes and hands and possibly a respirator as fumes can collect in an enclosed space like a garage or closet, have enough rags or towels handy for spills too. Provide adequate ventilation by opening doors or windows, and use fans if necessary. Attention boys and girls!
