Steam Boilers
Residential steam boiler systems are a type of central heating system commonly found in older homes and some specialty applications. They heat a house by producing steam, which travels through a network of pipes to radiators or convectors located throughout the home. As the steam releases its heat, it condenses back into water and returns to the boiler to be reheated, creating a simple and reliable heating cycle.
A typical residential steam boiler is fueled by natural gas or fuel oil and includes key components such as the boiler itself, a burner, pressure controls, a low-water cutoff for safety, a sight glass to monitor water level, and main and radiator vents to allow air to escape the system. Unlike hot-water boilers, steam systems do not use circulator pumps or expansion tanks; they rely on the natural movement of steam and gravity for condensate return.
Steam boiler systems are valued for their durability, quiet operation, and ability to provide even, comfortable heat. When properly sized, installed, and maintained, they can operate efficiently for decades. Regular maintenance—such as checking water levels, ensuring proper venting, and keeping controls clean—is essential to safe operation and optimal performance.
