The WOC55 Multi-Fuel Boiler is capable of producing 225,000 BTU/hr and will heat homes ranging from 2,000 to 5,500 sqft. It is a multi-fuel boiler perfect for homeowners looking for a simple, well-made boiler that can burn various fuels. Plus, the WOC55 allows the convenience of liquid backup all in one unit.
All WOC boilers can be upgraded to include an automatic switchover feature to oil if the water temperature drops due to a lack of fire. This option gives you the flexibility and freedom of knowing that your home will not go cold if you, for example, decide to go away for the weekend.

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.
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.
