Condensing boilers are high-efficiency heating systems that extract additional heat from the exhaust gases produced during combustion. Unlike traditional boilers, they utilize a heat exchanger to capture this heat, which would otherwise be lost, allowing them to achieve efficiency ratings of over 90%. This process not only reduces energy consumption but also lowers greenhouse gas emissions. These boilers are commonly fueled by natural gas or propane and are suitable for both residential and commercial applications. Their compact design and advanced technology make them a popular choice for modern heating solutions, contributing to energy savings and environmental sustainability.
