Here we discuss the diagnosis and repair of no-heat or leaks or other problems with heating radiators, including hot water radiators, heating baseboards, steam radiators, and other water-containing heating radiation devices such as heating convectors. Our photo above (at page top) shows a typical "one pipe system" steam heating radiator. A single pipe delivers steam to the radiator and condensate from the cooling steam returns to the heating boiler via that same pipe. Also see RADIANT HEAT.
This website answers most questions about all types of heating systems and gives important inspection, safety, and repair advice. The heating system articles provided at this website explain how to inspect and detect defects and hazards on heating systems, boilers, furnaces, and other equipment. Methods for saving on heating cost and on improving heating safety are included. If you don't know what kind of heat your building uses, see our introduction at BOILERS, HEATING. If your heating system is not working properly, see NO HEAT - BOILER / FURNACE DIAGNOSIS. Our photo (at left) shows a heating convector unit in a 1920's home in New York. A heating convector unit operates much like a radiator (page top photo) but instead of thick cast iron used to radiate heat, the convector is made of copper tubing covered with metal fins. As the convector gets hot, cool air is drawn up from floor level, is heated by the fins on the convector, and warm air is supplied out of the convector's front grille. Below we provide articles that help in diagnosing and repairing no-heat problems with each of these types of heat delivery systems. Criticism and content suggestions are invited from heating service technicians, home inspectors, and home owners. © Copyright 2009 Daniel Friedman, All Rights Reserved.

What to Check First if your Radiator, Baseboard, or Convector is Not Getting HotHere are links to some key articles that will help you correct a problem with heating baseboards or radiators that are not working:
Where to Check for Leaks on Radiators, Baseboards, ConvectorsObviously, first look at the floor around each heating component to see if you see water stains or water damage. (Water damage can occur at steam radiators too, as condensate could be leaking at the condensate return pipe fittings.) Here are some other common leak locations on heat radiating devices:
Sometimes a leak at a steam radiator is not critical - you may at least make it through the heating season, or the leaking may occur only when the radiator is cold (photo, above-right of a leaky steam radiator). If you see rust stains and leak indications between radiator sections such as in our photo (above-left) we recommend that you ask for repair advice from your heating service company. Leaks also occur at radiator valves, and at the piping fittings where valves and pipes join the radiator bottom or top. On heating systems using hot water baseboards, leaks can occur anywhere in the piping system, including at air bleeders located at the ends of baseboard sections, at couplings or elbows in the piping system, or where freezing has cracked or burst a heating baseboard pipe.
