What are the different types of green boilers?
Today, there are two main types of green boilers used in different industries: biomass boilers and condensing boilers. Each of these operates in completely different ways to reduce your carbon footprint.
Biomass Boilers
Biomass boilers operate by burning wood and other renewable organic materials to produce heat. There are automatic biomass boilers that control the amount of air and fuel that is used, making them even more efficient. To keep this boiler running, owners will need ample space to store the boiler, along with wood or logs for heating purposes.
Condensing Boilers
Condensing boilers are fueled by gas or oil. What makes these boilers different, is that they reuse heat from the initial burning process to preheat the water entering the boiler. Heat is recovered from the combustion process as water vapor is condensed into liquid, making the process more efficient. Unlike standard boilers, they come in various sizes that can fit into different locales and only require regular maintenance. Many buildings are switching from old gas boilers to condensing boilers due to their practicality.
