Welcome to The Heater Treater

We were the first to identify the need for scale protection with tankless water heaters and the first to provide a solution. 
If you install, sell, service or own a tankless water heater in a hard water area...the Heater Treater line of products has continued to be the proven leader and most widely recommended scale prevention unit for all tankless water heaters, tank water heaters, boilers and solar hot water systems.

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

We now know how important water treatment is for maintaining efficiency and extending the life of tankless water heaters, but often times water treatment still is 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.

The Heater Treater was developed by Dennis Falsken, a professional water treatment contractor with over 30 years experience in the water treatment industry. Being one of the first in his field to work directly with tankless water heaters, he immediately saw the need for an economical, effective way to reduce scaling in tankless water heaters.

The Heater Treater didn’t just happen, we put in many hours of research, field testing, utilized manufacturers input and our own experience to develop the first unit. This tradition continues with each new unit. Our history, experience with the tankless industry and product integrity is why the Heater Treater is the most widely used and recommended line of
scale prevention products on the market today.


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.

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) that does not allow any scale that might be created from adhering 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 treatment media is 100% food grade material approved by the FDA, NSF, and World Health Association. This media is also odorless, tasteless and colorless.
