Portage and Main manufactures boilers that can utilize different fuel sources such as wood, coal, or wood chips, wood pellets or other bio-mass.  The boilers come in various model and sizes and generate varying amounts of BTU's.  We look to size every boiler to the needed heat load for a given application or install.

Portage and Main boilersare designed and built to be installed outside and are fully capable of handling whatever the outdoor elements throw at them.  Quality construction and insulation ensure that the outdoor elements have minimal effect on the performance of an outdoor boiler. As an example, if a boiler has collected snow on its roof, then this snow will not melt as a result of any heat loss from the boiler.The snow will remain there until melted from the sum or warmer outside temperatures.

Boiler Operation - conventional boiler

The wood burning boilers are a manual load system that woudl typically require loading with firewood twice a day in cold temperatures.  A boiler system that is adequately sized to its application generally will burn for 12-14 hours on a load of fuel, in colder temperatures.  The boilers have minimal electrical components; simply a blower fan and two aqua-stats.  The primary digital aqua stat regulates the temperature of the boiler water, and controls the fan operations to re-thermthe boiler water temperature when required, to its
