Steam-Heating Services In Tennessee
Steam heating systems are seldom installed now in small residential buildings but are still common in many older ones. They are simple in design and operation, but require a higher level of maintenance than modern residential heating systems.
Unless the steam system is in good working order and adequate plans can be made for its upkeep, consider replacing it with a more maintenance-free system.

►Boiler. Steam boilers are physically similar to hot water boilers and should be inspected similarly.
►Boiler controls. Unlike hot water boilers, steam boilers operate only about three-fourths full of water and at much lower pressures, usually 2 to 5 psi. Steam boilers should be equipped with a water level gauge, a pressure gauge, a high-pressure limit switch, a low water cut-off, and a safety valve.
Often air vents need cleaning and supply valves need tightening, or valve packing needs to be replaced. Pounding near the radiator can often be cured by lifting one edge of the radiator slightly; this reduces condensate blocking in the pipes.
HYDRONIC HEATING SYSTEMS
Hot water from a boiler or hot water heater is the medium for heat transfer in a hydronic system. Radiators are the most common source of heat transfer, but radiant loops are gaining popularity. Installation and materials costs have made aluminum finned copper tubing the most effective style. Once the heat loss of a room has been determined, a measured length of baseboard (low output or high output) or the correct size free standing cast radiator can be installed. Baseboard, whether copper or cast iron, is run in a continuous loop from room to room, but the
larger cast standing radiators work better as a supply and return loop or as a monoflo loop. Using a fitting called a monoflo T, One pipe can feed the entire loop of standing radiators. Unique but simple, the monoflo T uses an orifice placed to one side of the t arm to restrict the flow of water through it. Down side of the flow it forces water into the arm. Upside of the flow and suction is produced. Water is forced in and out of the radiator without valves or a separate pump.
