WOC40 Multi-Fuel Boiler

Ten Year Warranty

The WOC40 is the smallest Multi-Fuel boiler we offer, able to heat homes ranging from 1,000 – 4000sqft. They are perfect for homeowners looking for a rugged, durable boiler with the ability to burn a variety of fuels plus allow for liquid fuel backup.

An Automatic Switchover feature to oil if the water temperature drops when the fire goes out is an available upgrade on all WOC models. This option gives you the flexibility and freedom to know that your home will not go cold if you, for example, decide to go away for the weekend.

The WOC40 comes standard with

  • #2 Fuel Oil Burner with Manual Switch-Over
  • Legacy Grate System
  • Large 14” Loading Door
  • Automatic Dual Draft System – Forced Draft Blower and Natural Draft Damper
  • Firebrick Lined Firebox
  • Water Cooled Baffle (for increased efficiency)
  • Hydro Tested to 60PSI
  • Constructed of ¼” Steel Plate
  • Honeywell Circulator Control Aquastat
  • Temperature/Pressure Gauge
  • ASME Tested Pressure Relief Valve
  • Load Door Smoke Flap

The WC40 Multi-Fuel boilers’ cost of ownership is one of the lowest in the industry—$40.00 – $50.00 per year on average!

Traditionally, Multi-Fuel boilers have been sold as wood/coal combinations. However, due to EPA Phase 2 regulations, these units are no longer sold for continuous use with wood.

Propane/Natural Gas Backup

Fuel oil backup is standard for WOC models but propane or natural gas back up options are available for an additional cost.

Automatic/Manual Switching

For #2 fuel oil, the backup system can function in an automatic switch-over scenario, with fuel oil taking over when the boiler has exhausted its coal fuel. For other fuels, such as natural gas or propane, switch-over is manual only.

Alternate Heating

Domestic Coil

This Domestic Coil features a 100° F rise at 5 gallons per minute, 50° water inlet temperature and 65 PSI water pressure. It is threaded into a 4 IN NPT threaded fitting provided on the boiler for this purpose

Insulation Jacket

Our base unit Multi-Fuel boilers have no insulation on the outside of the boiler, allowing maximum heat radiation in the boiler room. If you prefer to circulate more of this heat, an insulation jacket can be added to the boiler. This insulation jacket is comparable to that used on the Wood Gun or Coal Gun boilers

ASME Certification

The ASME Certification guarantees the steel grade and weld quality of the boiler water jacket. Each ASME Certified water jacket has been pressure tested to 60 PSI, and includes a 30 PSI release valve.

Low Water Cutoff

A Low Water Cutoff senses the water level in the boiler’s vessel and will shut the unit down if the water level drops to an unsafe level. Available with automatic reset or manual reset.
