Installing Baseboard Radiators

Baseboard radiators provide heat more inexpensively than a furnace does. The baseboard area in a room is a great place to install a heating system because hot air rises. Heating a room from the floor up is a very efficient use of energy. Water boiling in a tank heated by gas, oil or electric is transmitted through a separate plumbing system to the radiators installed along the room baseboard. Because this is a totally enclosed system using water creating hot steam that radiates into the room, the system is extremely efficient and clean since there is no dust to accumulate in duct work and blown throughout the house exiting through heating vents. They are also extremely quiet.

Read Literature

Read literature about hot water baseboard heating to discover the rating per linear foot you need to meet. Choose any water temperature a baseboard heater can maintain. Keep in mind that using lower temperatures means you’ll need to install more baseboard heaters. However, installing too much will overheat a room. But if you install enough baseboard heating to properly heat all walls and windows, you will cut down on drafts providing a surrounding warming effect when heaters are installed on each wall of a room. Always install baseboard radiators under windows. Consult the manufacturer’s directions for calculating the total linear feet of baseboard heating required.

Install Heaters


  • Drill floor holes large enough to connect to copper tubing that supplies hot water from the system boiler. Make sure the holes are wide enough to accommodate expansion. Once tubing is inserted in the holes, seal these with flush in grommets or silicone caulking to prevent air leaking.
  • Fasten baseboard heaters in the center of each wall when running more than 12 feet per room.
  • Install vents at alternating heater locations to release any trapped air. There are three types:
  1. Fiber disk- attached to fittings providing air circulation. These elbow shaped fittings can easily fit under a baseboard heater cover.
  2. Automatic float-type – are vents used with a diaphragm-type tank. Leave open for one week after installation then close to prevent oxygen exchange.
  3. Manual – vents are installed as elbow shaped fittings that consumers operate to vent any trapped air in the system

Installing a Baseboard Cover

Installing a baseboard heater cover creates better heat distribution throughout the room. Baseboard heaters can allow for a directional push from the heat emanating out of the radiator by a designed flange extrusion that pushes hot air toward the center of the room. Without a directional guide provided by a baseboard heater cover, the hot air simply rises along the surface of the wall until enough hot air expands toward the center of the room. The baseboard cover also acts to “hide” the baseboard radiator. Consumers have the opportunity to purchase covers that are quite decorative and come in a variety of colors. Choosing a color that matches the wall will help “hide” the radiator making it less conspicuous to the eye.

Surf the Internet checking baseboard radiator pricing. Many manufacturers offer online purchase discounts that can save you considerable money.
