The AHS Multi-Fuel boiler is available in configurations that allow you to burn wood and coal or wood and coal with liquid fuel backup. Coal configurations are optimized for burning anthracite coal but a special package is available to enable the burning of more common bituminous coal.

Liquid fuel backup enabled models include a separate firing chamber where fuel oil, natural gas, or propane is combusted.
