THERMO 2000 VoltMax SCR VOLTSCR24055P1 Commercial Electric Boiler | 55 kW - 240V 1 Phase

55 kW of central hot-water heating for your apartment building on a 240 V supply

For buildings heated by radiators

Many apartment buildings in Montreal, Longueuil and Laval are heated by a single central boiler that feeds radiators in each unit. When that boiler reaches the end of its life, Thermo 2000’s VoltMax 55 can take over. Running on 240 V single phase, it delivers 55 kW, or 187,660 BTU/h, to the building’s hot-water loop.

The VoltMax SCR is the manufacturer’s commercial electric boiler, designed for commercial, institutional and multi-unit buildings. It also suits radiant floors and hydro-air systems, if the building has them.

Tenant comfort, tuned to the weather

A radiator network does not need the same water temperature in November as in January. With the included outdoor sensor, the Schneider Electric controller adjusts water temperature to the weather, within a setpoint of 50 °F to 200 °F (10 °C to 93 °C). The solid-state relay (SCR) then varies output from 0 to 100%. According to Thermo 2000, this modulation limits peak power demand, and the unit stays quiet, clean and low-maintenance.

The units’ hot water can also go through the boiler. The controller provides a second setpoint for an indirect water heater and a pump contact with or without domestic hot water priority.

Inside, Incoloy immersion elements in two sizes do the work: 5 of 5 kW and 5 of 6 kW. They are replaceable, and the controller rotates the order of the stages.

Boiler room and electrical service: what to check

Thermo 2000 publishes a current of 229.2 A for this model. First, we check that the building’s electrical service can take it, on top of the other loads. In the boiler room, the VoltMax 55 takes up little space: the documentation calls for 3 in of clearance on the sides and back, 24 in at the front and 32 in above, and the unit can sit on the floor. It weighs 310 lb (141 kg) and holds 11 US gal of water.

The circulator and expansion tank are not among the supplied parts, and the low water cut-off is an option at 55 kW. We list them in the quote based on your network.

AirGreen, from estimate to commissioning

We start with a free on-site estimate, then give you a written quote. On installation day, our technicians remove the old unit, set the VoltMax in place, connect it to the loop through its 1 1/2 in NPT side connections, make the electrical connection, mount the outdoor sensor, fill and purge the network, then set the heating curve. We schedule the work with you to keep the tenants’ time without heat as short as possible.

AirGreen is a family business established in Montreal for more than fifteen years, holding RBQ licence 5645-9605-01 in ventilation, refrigeration and electrical work. Thermo 2000 covers the tank for 10 years (limited warranty, closed-loop heating) and the electrical and mechanical components for 2 years.
