Simple, easy to use kit. Mix the solution, hook up the hoses, run the pump 20 mins, flush the line and done! I will add that your inlet/outlet lines from the coil/heater must have a valve or hose bib hooked up to accept the hoses. In our "new" house, we have a well, and apparently hard water. Being on city water in our last house, I was not familiar with the issues of scale, sediment, water quality of a well water system. Now I know! We had virtually NO hot water at all, used this kit and now have good pressure and hot water! There was so much scale in the bucket when I was done, I was shocked! I am now looking into filtering/softener systems to put in. Sorry I didn't get a pic of it with the nasty water while it was working.

    What caught my eye is that this is a complete kit, including flushing chemicals. However, it proved to be a bit pricey compared to piecemealing a flush kit together. Notably it was easy to use and by the appearance of the dirty fluid in the bucket, the chemical flush appeared to have done a good job. In summary it seemed to do a good job of flushing my tankless water heater, but its somewhat expensive.
