HydroTherm will feature its two newest products - the KN-10 self-adaptive boiler and S1000B programmable controller. The KN-10 is a commercial, gas-fired boiler with a self-adaptive design that is tolerant to changing conditions, says the manufacturer. It provides high efficiency and a small footprint, the company says. The S1000B programmable controller is designed to enable users to control heating boilers, domestic hot water boilers, motorized valves, combustion air dampers, draft inducers, and more from remote locations.
