Water is often heated in a boiler and distributed throughout a building’s interior through copper and/or plastic (PEX) pipes. Even while high-efficiency boilers are more costly to install, they more than makeup for it in the long run with their decreased energy costs. In fact, according to the United States Department of Energy, replacing an outdated boiler system with a new high-efficiency one may save fuel costs by as much as 50 percent. High-efficiency boilers are an investment; like a vehicle, they need regular maintenance and boiler repair in Staten Island to preserve their value.
