    Why An Add On Furnace Is A Good Investment For Every Homeowner

    If you are looking for a way to burn coal or wood without sacrificing the efficiency of your current furnace and heating system, consider the benefits of installing a Big Jack add on furnace to your home. This multi-fuel furnace is made of thick steel and heavy-duty material, and can be added to your current duct system to increase the energy efficiency of your home. This multi-fuel furnace is not something that can simply be purchased at your local discount store, and the increased heat and warmth in your home will be your reward for investing in an add on furnace that is built to last.

    With a Big Jack add on furnace, twenty percent of the air that runs through your furnace is directed from the combustion fan to the fire. This secondary air is then blown above the fire to ignite unburned gases and smoke that are created by the main fire in the furnace. The result of this process is wood burning that is high in efficiency, and translates into a comfortable home for your family that doesn't cost a fortune and doesn't rely on sources that are low in supply such as oil and gas.

    The Big Jack add on furnace is simple to operate for even the most inexperienced furnace users. Simply put the kindling in, use a match to light it, and increase the temperature on the thermostat. This process switches the combustion fan on in order to get the wood burning. The furnace works automatically at this point. The thermostat in the room will tell the combustion fan to switch on when the temperature is not quite warm enough, and will tell the fan to switch off once the temperature is comfortable and where you want it. The circulating blower is controlled automatically by a fan control mounted above the firebox.

    Many Americans are opting for adding solid fuel furnaces to their already existing heating system to increase the energy efficiency of their homes and to decrease utility bills. Your investment in a Big Jack will pay off many times over the lifetime of your furnace.
