AltSource 120 1 Phase 4.5 kW - 60 kw

AltSource 120 1-Phase Commercial Electric Boiler & Storage Tank (4.5 kW - 60 kW)

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.
