what is a hot water boiler furnace

Furnaces and Boilers | Department of Energy

Furnaces and Boilers. Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil. Steam boilers operate at a higher temperature than hot water boilers

How to Care for Your Hot Water Heating System - dummies

Most hot water systems have a single gauge that measures three things: pressure, temperature, and altitude (the height of the water in the system). Monitoring the pressure is important. Most boilers run with only 12 to 15 pounds of pressure. The boiler can become seriously damaged and even dangerous if the pressure exceeds 30 pounds.
