Residential Boilers - Oil Boilers Series WBV® Boiler

The Series WBV® residential, oil-fired boilers are available for use with both hot water and steam systems and designed for natural draft (chimney) venting. The fully-packaged or knockdown boilers are available in 3 sizes (3-5 sections) with 8 firing rates. Features of the Series WBV® boilers include a full plate swing-out door and convertible rear to top flue outlet (for 3 and 4 section boilers only). Water boilers include Taco circulators and HydroStat reset controls with low water cut-off. Steam boilers include Honeywell operating controls and probe type low water cut-offs. A deluxe, insulated enameled steel jacket on all boilers reduces heat loss. The cast iron sections are assembled with steel push nipples and factory tested to assure a water tight seal.
