Dual Fuel

​Dual fuel refers to systems or engines that use two different types of fuel to operate. Here are some common applications:

Dual Fuel Engines: These engines can run on a combination of two fuels, typically diesel and natural gas. The diesel fuel acts as the ignition source, while the natural gas provides the bulk of the energy 1 2. This setup can improve fuel efficiency and reduce emissions.

Dual Fuel Heating Systems: These systems combine an electric heat pump with a gas furnace. The heat pump is used for heating and cooling during milder weather, while the gas furnace takes over during extremely cold conditions 3. This hybrid approach maximizes energy efficiency and comfort throughout the year.

Dual fuel systems offer flexibility, cost savings, and environmental benefits by optimizing the use of different fuel sources based on availability and efficiency 2.
