the Heater Treater

Low cost hard water scale protection for all tankless water heaters. Economical enough to include on every tankless water heater installation.

How It Works

The Heater Treater is installed on the feed water line just prior to the tankless water heater. As the water passes through the filter cartridge, the treatment media (uniquely located in the interior of the filter) slowly dissolves into the water supply, providing scale protection to the heater in several ways.

Is the treatment media safe?

The treatment media is 100% food grade material approved by the FDA, NSF, and World Health Association. This media is also odorless, tasteless and colorless.


The treatment media interferes with the ability of the calcium and magnesium to crystallize or become scale when heated. This by itself is a very effective scale prevention process.


It lays down a thin protective coating on the interior of the heater (most importantly the heat exchanger) which does not allow any scale that might be created to adhere to the interior of the heater.


The 5 Micron filter provides added protection from rust, sediment or debris that could affect the operation of the heater.


The appropriate amount of treatment media combined with the flow rate introduces the correct dosage for effective scale prevention throughout the life span of the cartridge.


The location of the treatment media is very important. Unobstructed areas on both ends of the filter allow for increased water flow, extending the life of the media. This lowers the maintenance cost, giving the filter cartridge a longer effective life span.


We have our own clips designed specifically for the filters we use. These clips hold the treatment media firmly in place without the use of a foreign substance, such as glue.

the Heater Treater

Scale protection is important for maintaining efficiency and extending the life of tankless water heaters, but oftentimes water treatment is still not utilized due to the additional cost. the Heater Treater is the simple, low-cost solution for protecting all tankless water heaters from the effects of hard water scaling.
