AltSource 120 3 Phase 6.8 kW - 60 kw

AltSource 120 3-Phase Commercial Electric Boiler & Storage Tank (4.5 kW - 60 kW) With / Without Copper Coils The AltSource 120 is the only high-volume electric boiler on the market designed specifically for commercial applications. Unique and robust, this unit combines a boiler and storage tank to act as a secondary energy source, maximising the efficiency of any renewable energy system. Thanks to its static SCR relay, the unit modulates its power from 0 to 100% to provide perfect thermal stability and increased component longevity. Available in single-phase and three-phase configurations, it offers significant space savings while eliminating costly consumption peaks. Virtually maintenance-free, the AltSource 120 is the sustainable choice for optimising the energy performance of your buildings. The system is backed by a 10-year warranty on the tank and coils, and a 2-year warranty on electrical and mechanical parts. Maximize your commercial energy savings and heating performance with the Thermo2000 AltSource 120. Designed specifically for large-scale residential, multi-unit complexes, and light commercial applications, the AltSource 120 is the only high-volume electric combination boiler and storage tank series of its kind on the market. Acting as a powerful thermal battery for your hydronic system, it seamlessly integrates with and optimizes the performance of renewable energy setups (like heat pumps, geothermal, and solar thermal) as well as traditional boilers. Equipped with a 120-gallon capacity tank and a wide array of single-phase power options ranging from 4.5 kW up to 60 kW, this heavy-duty unit delivers precise temperature regulation, peak energy efficiency, and reliable back-up energy when demands are at their highest. Key Features & Benefits High-Volume Thermal Mass: Functions like an energy reservoir, storing heat when production is high and releasing it smoothly during low-capacity or peak-demand periods to cut operating costs. The Ultimate Renewable Partner: Purpose-built to maximize the efficiency and output of geothermal systems, solar setups, and low-mass boilers. T2 UltraSmart® Controller: Features precise multi-stage power modulation and outdoor temperature reset sensor adjustments to ensure optimal comfort and zero energy waste. Virtually Maintenance-Free: Robust engineering and heavy-duty steel construction mean minimal upkeep over an exceptionally long service life. Eco-Friendly & Safe: 100% efficient operation with zero indoor combustion or greenhouse gas emissions, protected by high-density, eco-conscious insulation.
