Works Well for Descaling, But a Bit Pricey
I would give this Chromex NSF Certified Tankless Water Heater Descaling Solution 4 stars. The product does exactly what it's supposed to do and helped restore the performance of my tankless water heater. The solution was easy to use and worked effectively to break down mineral buildup and scale deposits. After running the descaling process, I noticed improved water flow and more consistent heating performance. It's reassuring that the formula is NSF certified, which adds confidence when using it in a system connected to household water. The quart-sized bottle was sufficient for my maintenance needs, and the instructions were straightforward. It appears to be a quality product designed specifically for tankless water heater maintenance. The main downside is the price. While it works well, it feels a little expensive for what it is, especially considering it's essentially a cleaning solution that may need to be purchased regularly as part of routine maintenance. A larger quantity or a lower price point would make it a better value. Overall, it's an effective descaler that gets the job done and helps maintain heating efficiency. Despite the cost, I would still recommend it to anyone looking for a reliable and easy-to-use descaling solution for their tankless water heater.

It works pretty well
I have used this before and it works pretty well. After flushing the water heater for 45 minutes, the solution was pretty dirty.

It works
It worked I'd say in getting rid of the descaling on my heating elements using a closed loop from a bucket for recirculating the product for 30 mins was about 85% and did seem to reopen water ways for heating the water allowing better water pressure

no pierdes su tiempo utilizando vinagre
Empecemos a tener variaciones en el flujo y consistencia del agua caliente. Despues de diez años me di cuenta que el calentador necesitaba ser descalcificado cada año.En el internet recomendaba utilizar vinagre. Tal vez vinagre funcionaria usandolo desde un principio pero con el sarro acumulado a travez de 10 años. no fue muy efectivo. La foto con el agua verde es vinagre despues de circular por una hora. Si salio unos cuantos granos pero casi nada. Con Chromex si se nota la diferencia. La otra foto es una hora circulando solucion con Chromex. Salio mucho mas sarro. Ya no varia la temperatura del agua caliente y no se apaga solo. Pienso volver a hacer la limpieza en unos 4 meses mas a ver si sale mas sarro. Muy recomendado. Doy 4 estrellas y no 5 por el precio.
