Nothing reduces water heater efficiency more than hard water mineral scale. Accumulating on heating elements, it slowly reduces both heat transfer and water pressure, leading to lower performance, and it may cause premature failure. Preventing mineral scale formation with the Stiebel Eltron Scale TAC-ler ensures your water heater's optimal performance and service life.

Scale TAC-ler is a salt-free water conditioner compatible with all tankless and conventional tank-style water heaters. Scale TAC-ler is installed on the cold water inlet of the water heater, where it treats the water entering the water heater. It will provide protection for flow rates up to 6 gallons per minute.

How Scale TAC-ler Works

Scale TAC-ler salt-free water conditioners use a specialized polymeric bead medium that serves as a catalyst for the formation of calcium and magnesium carbonate nano-crystals. Instead of forming hard mineral scale on surfaces, these microscopic crystals of calcium and magnesium carbonate remain suspended in solution and pass through to the drain. This process is called Template Assisted Crytallization, or "TAC." A university study determined that TAC technology was the most effective of all non-salt water conditioners at preventing mineral scale, with reduction levels consistently in excess of 90%.
