Important Information

If you are a homeowner protect your investment - if you are an installer protect your reputation... ask for the Heater Treater® by name, don't accept an imitation.

The Heater Treater®
was the first scale prevention product specifically designed to protect tankless water heaters from the effects of hard water scaling. Created over 10 years ago, the Heater Treater® is the proven industry leader and most recommended scale prevention unit on the market today!

Provides scale protection for all tankless water heaters, tank water heaters, boilers and solar hot water systems.






HOW the HEATER TREATER® WORKS and FAQ...


How it Works…


An FDA and World Health Approved water treatment media is loaded inside the filter cartridge. As the water passes through the filter this media slowly dissolves into the water supply where it provides two very important, but very different types of scale protection. First this media surrounds or encapsulates the calcium and magnesium ions which reduces the opportunity for these ions to crystallize (create scale) when heated. Secondly the treatment media lays down a microscopic thin protective coating that does not allow any scale that may form from adhering to the interior of the tankless water heater. These two processes together provide effective scale protection for tankless water heaters, boilers and solar heating systems in hard water areas.

How Often Do the Filters Require Replacing...

  • A residential installation on a city or municipal water supply the filter should be replaced yearly.
  • A commercial installation on a city or municipal water supply the filter should be replaced every 6 months.
  • There are exceptions due to water quality, water usage etc.

What Purpose Does the Gauge Perform…


Reduction of the water pressure on the exit side of the unit is an indication of the filter cartridge has collected enough sediment, dirt, rust etc. to lower the pressure and reduce flow to the tankless water heater. This reduced flow and water pressure, if not corrected will eventually affect the operation of the heater.
This is monitored and recorded with the initial installation. When the gauge shows a 10 psi reduction of pressure, it is time to replace the filter due to sediment and dirt collection only.
Another very important purpose of the pressure gauge is to indicate if high water pressure is present. A reading over 80 psi indicates that the pressure regulator has failed and needs to be replaced or that a pressure regulator should be installed to protect against a major plumbing failure due to high water pressure.

I Am Confused About the Filter Replacement Intervals – Do I replace Yearly or When the Gauge Indicates It's Time for A Change...


There are two reasons for replacing the filter…

The most important reason is to replace the filter before the treatment material loaded inside the filter is completely used up. If this material is not present it will not be able to protect the heater. For this reason we suggest replacing the filter using the intervals of 9-12 months on residential installations and every 6-9 months on commercial installations. These intervals will vary due to water usage...please call us if you would like help determining how often to change the filter in your system.

The next reason is when the filter collects enough sediment, dirt, rust etc. that the operation of the heater is potentially affected due to reduced flow or low water pressure. The filter by capturing the sedimentation in the water has provided additional protection to the internal parts and operation of the heater. Excessive sedimentation can happen from various sources…old water distribution lines in a town or city, private wells, old plumbing, amount of water usage, distribution line repairs etc.

So a simple way to determine when to replace the filter is this…replace the filter using the suggested intervals - or when the gauge indicates a filter change is required prior to these intervals due to sediment collection.

I See You Have 4 Different Units – How Do I Know Which One to Choose for My Application…


We made this very simple. The units are rated just like tankless water heaters in gallons per minute of water flow. Using the manufacturer’s specifications for your specific heater use the maximum GPM of hot water produced by this heater to match up to “the Heater Treater®”. You can also call us for help determining the correct unit for your application.

tHT-10….5.0 GPM Single heater applications rated at less than 5.0 GPM 3/4" Inlet & Outlet
tHT-20….9.8 GPM Single heater applications rated at less than 9.8 GPM 3/4" Inlet & Outlet
tHT-BB…15.0 GPM Single or double heater applications 15.0 total rated GPM 1" Inlet & Outlet
tHT-BB-HFC-50….50.0 GPM Multiple heaters with a combined flow rate of less than 50 GPM 1.5" Inlet & Outlet


Does “the Heater Treater®” Have a Warranty…


Yes…each unit carries a limited 3 year warranty for material and workmanship. Each unit also comes serial numbered and with a warranty card that can be mailed in or entered online.

Any Restrictions on Where the Units Can be Installed…


The units can be installed inside or outside. Use common sense when installing - protect from freezing and if possible keep out of direct sunlight.
