Harvia Water Softener Unit | HWS1500US

Automatic Water Softening System for Steam Generators, Combi Heaters & Commercial Wellness Equipment

The Harvia HWS1500 Water Softener Unit is an automatic water softening system designed for commercial and high-use applications where clean, softened water is essential for protecting steam generators, combi heaters, and other water-fed sauna and spa equipment. By removing hardness minerals from incoming water, the system helps deliver purified, softened water that supports reliable operation and long-term equipment performance.

Hard water contains calcium, magnesium, and other dissolved minerals that can contribute to limescale, mineral buildup, surface staining, and premature wear inside steam equipment. The Harvia HWS1500 is engineered to remove nearly all of these hardness minerals before water reaches your steam system, helping reduce maintenance requirements while protecting valuable internal components.

Automatic water softening improves the efficiency and lifespan of steam equipment by minimising hard water damage and maintaining cleaner internal water pathways. It also helps reduce unwanted odours and mineral deposits that can affect system performance over time.

The HWS1500 is particularly well suited for commercial wellness facilities, spas, hotels, retreat centres, fitness clubs, and high-use residential installations where consistent water quality is critical. By providing continuous softened water, it supports dependable steam production while helping reduce long-term maintenance costs.

At Between Living, we believe that clean water is one of the foundations of a reliable wellness environment. Genuine Harvia water treatment systems help protect your investment while ensuring your steam equipment performs at its best for years to come.
