Most gas and oil boilers do not have an external air source to feed the boiler. Instead the air is taken from the surrounded air space in the basement. This allows the burning to use air that is laden with dust which causes the boiler burn chamber to become dirty. A dirty burn chamber will cause the boiler to run less efficient which will increase your energy cost.

Your gas or oil boiler should have an external air source ducted to the boiler from outside the house. A fresh outside air source will provide clean air to the burn chamber keeping the boiler operating at a high efficiency. Installing an external air supply is an easy DIY project.
