Customer Reviews for Hercules Haymaker Tankless Water Heater Descaler

The descaler worked great . I get hotter water faster.

Great product for once a year flushing of tankless water heater

Worked well with my pump setup. Recycled water turned an off green during the cleaning process. The fresh water flush brought out additional calcium from the heater. Pleased with the renewed efficiency of the water heater.

It decalcified the tank so well that it started leaking and I had to buy a new one.

Very easy to use with good results.

I descaled my rental's on demand hot water gas boiler twice after my tenant complained that it was making a banging noise. This unit has probably never been descaled. I used Haymaker first, following all directions but still my tenant complained. Second, I used distilled vinegar. No complaints since.

Product perfromed very good, circulated it for an hour thru my instant water heater removed deposits and increased efficiency.

I let this circulate for about 50 minutes and the solution was dirty, so I assume it did it's job.

Worked as it should highly recommend

Hercules Haymaker Tankless Water Heater Descaler is good for descaling the tankless heater, but also will clean the AC drain pan from any rust! You can dip in this liquid any rusted metal and in a few minutes or hours will look like new. Just don't put it on your skin. Now the tankless heater takes less time to heat the water. We need to clean it every year ...it's a must do

Works great product for the price

The product worked well. I perform the cleaning every six months.

Worked as it said it would. It appears to be acidic ( dripped a bit on a concrete basement floor and saw fizzing) so protect your skin. Let it run for about an hr. The solution was disgustingly dirty and rust colored.

Hercules, haymaker tankless water heater Descaler worked really good. In fact, it worked better than using vinegar on my last water heater flush. It removed much more of the descaling from my tankless water heater, which was visible in the bucket. I definitely would recommend to my friends and anyone else.

Very good product!!!

After running circulation pump for about 30 minutes solution went from clear to very blackish. Solution looks to have cleaned water heater of minerals build up.

Simple and did the job.
