High-efficiency boilers are advanced heating systems designed to convert fuel into heat with minimal energy loss. They achieve this by utilizing technologies such as condensing heat exchangers, which capture and reuse heat from exhaust gases. This results in higher energy efficiency ratings, often exceeding 90%, compared to traditional boilers. These boilers are commonly powered by natural gas, propane, or oil, making them versatile for various applications. By using high-efficiency boilers, homeowners and businesses can reduce energy costs and lower greenhouse gas emissions, contributing to a more sustainable environment.
