THERMO 2000 VoltMax SCR VOLTSCR20856P3 Commercial Electric Boiler | 56 kW - 208V 3 Phase

56 kW on 208 V three phase, with output that follows demand instead of running all or nothing

Why SCR modulation matters in a building

A conventional staged electric boiler switches its elements on and off in blocks. Thermo 2000’s VoltMax SCR adds a solid-state relay that varies output continuously from 0 to 100%, with relay stages as a complement. According to the manufacturer, this modulation limits the boiler’s peak power demand. The controller also rotates the order of the stages, and the included outdoor sensor sets water temperature by the weather, with a setpoint of 50 °F to 200 °F (10 °C to 93 °C).

What the VoltMax 56 is and where it goes

This model delivers 56 kW, or 191,072 BTU/h, on 208 V three phase. It heats the water loop of a condominium building, an office building or a mixed-use building: radiant floors in the units, radiators, the coils of a hydro-air system. A second setpoint supplies an indirect water heater when needed, with or without domestic hot water priority.

In a condominium building, the boiler room is often the responsibility of an association run by volunteer directors. The Schneider Electric controller makes their job easier: a web page and email alarms through the Ethernet port, alarm codes on a 3 in backlit display, in French or English. If the building has a management system, communication runs over BACnet IP or MS-TP.

Before ordering

Thermo 2000 publishes a current of 156.4 A for this model; that is the value we compare with the building’s electrical service. The boiler is vertical and compact. It requires 3 in of clearance on the sides and back, 24 in at the front and 32 in above, and sits directly on the floor. It weighs 310 lb (141 kg) and holds 11 US gal of water. Its four 1 1/2 in male NPT side connections tie it into the existing piping.

Two items are added to the order: the circulator and the expansion tank, which are not on the list of supplied parts. The low water cut-off is optional on this size; Thermo 2000 installs it as standard above 60 kW.
