At junction points inside ductwork, dampers open and shut to control airflow. This allows for greater control in air distribution.

Decoking Rod

A tool used in NordicStove oil drip heaters to remove carbon deposits or "coke" that can accumulate on the burner or combustion chamber surfaces over time. These carbon deposits can hinder the efficiency of combustion, leading to reduced heating performance and potential safety hazards. The decoking rod is inserted into the burner or combustion chamber to dislodge and remove these deposits, allowing for cleaner and more efficient burning of the fuel oil. Regular use of the decoking rod helps maintain optimal performance and prolongs the lifespan of the oil drip heater.


The process of removing excess moisture from the air in heating systems, improving comfort and preventing mold or moisture-related issues.

Differential Temperature Controller

A device used in hydronic heating systems to maintain a consistent temperature difference between supply and return water, optimizing system efficiency.

Direct Fired Heater

A heating device that directly burns fuel to generate heat, often used in industrial or commercial applications for space heating or process heating.

Direct Vent

Direct vent refers to a type of venting system used in heating appliances, where combustion air is drawn from outside the building and exhaust gases are expelled directly outdoors through a dedicated vent pipe. This setup ensures that indoor air quality remains unaffected by combustion processes, while also maximizing heating efficiency and safety.

Domestic hot water

A hot water heating system used for household purposes.

Double Wall

A chimney constructed of an inner liner and outer shell, reducing conduction of heat to the outside. This allows the chimney to be installed without combustion danger to support materials.


Draft refers to the flow of air or combustion gases through a chimney, flue, or venting system. In heating systems, draft is crucial for proper combustion and the removal of combustion byproducts, ensuring efficient and safe operation of the heating appliance.

Draft Hood

A safety device installed on gas-fired appliances to ensure proper venting of combustion gases and prevent backdrafts.

Draft Inducer

A fan or blower used to create draft or airflow in heating systems, assisting in the combustion process and venting of gases.

Draft Regulator

A device used to control the draft or airflow in chimneys, flues, or venting systems of heating appliances, ensuring proper combustion and venting.

Draft Tube

A draft tube in heating applications is a metal/high-temp plastic pipe, or duct that connects the combustion chamber of a heating appliance to the chimney or flue, facilitating the flow of air and exhaust gases for combustion and venting purposes.
