The majority of the Electric Boilers including Mini-Size Boilers, Midi-Size Boilers, TS Series and Commercial Boilers with hydronics heating, installations have several zones or thermostats in various rooms. When one thermostat calls for heat it represents only a partial load to the boiler. In most dual heat installations this Electric Boilers are plumbed in series with an existing oil, gas, or wood boiler. For gas or oil, the Electric Boilers is generally at the gas/oil outlet; but for wood, the Electric Boilers including must be on the inlet sides. The standby boiler cannot be operated as hot boiler. This will defeat the Electro-Boiler. Rewire as required using EB-S-SB, standby boiler is turned on from the brown wires. In the case of existing fossil fuel boiler conversions, it is assumed the expansion tank, valving, air bleeder, and circulation pump are in place, in good operating condition, and adequate for the overall system design. In the case of new installation (floor radiant or baseboard), use standard hydronics water heating practices for the necessary expansion tank, air bleeder, valving, water pump, etc., sized for the total capacity of the system. The Electro-Boiler is turned on with an R and W closure from the zone system wiring.
