TS Commercial Series

18 to 54 kW

The TS Commercial Series boilers are designed to meet the needs of all your hydronic heating applications. WarmFlo® temperature control allows you to select a wide range of water temperature outputs. Modulating element control allows for precise water temperature control in high water temperature set point applications such as baseboard and radiator heat. This series is also ideal for multi-zone radiant floor applications where water flow can vary by zone. Enable outdoor reset and your Electro-Boiler can anticipate your heat demand, increasing or decreasing water temperature for even greater operating efficiency.

 The TS Commercial Series is available in a variety of kW outputs, with single and three-phase voltage options. This series is sized to handle those large radiant heat applications in a convenient wall-mount package.
