Improving your existing steam system efficiency.

1. Make sure all the steam piping in the basement is insulated. No need to insulate the return pipes. If you have insulation removed from the steam pipes for basement heat replace it. This is an expensive way to heat even a small area. See adding a baseboard loop in your basement, then click the back button.
2. Verify the near boiler piping is correct. Incorrect near boiler piping produces either short cycling or wet steam. Both of these conditions increase fuel bills.
3. Verify all system vents are working properly. Everyone pipes system requires working radiator vents. NO AIR VENT SHOULD EVER VENT LIVE STEAM!!!!
4. The main line vents also need to work. They must also vent fast enough. This may require the use of two or more main line vents in the same location. See vents on the above link.
5. Reduce the steam pressure. The Cut-out or main steam pressure should never be set above 2 psi. Most systems today are operating lower than 2 psi even in the ounces range. If the setting is too low it may cause short cycling which will increase fuel consumption.
6. Maintain the water level where the manufacturer says it should be, even if you have an automatic water feeder. Remember an automatic water feeder does not take the place of you maintaining water levels. The automatic feeder is for use when you are not able to check and maintain the proper level.
7. Replace your thermostat with an electronic thermostat. The old thermostat calibration may become out of adjustment or a dirt/dust buildup on the mercury bulb affecting the accuracy of the thermostat. It may cause the heat to run longer than necessary or causing an uncomfortable temperature swing. Make sure you set the thermostat for a steam system in the menu or dip switches.
8. Make sure the return lines are working properly. The condensate coming back could be slowed down causing the need for more makeup water. The more makeup water you add the more fuel is used to bring the makeup water to 212º. Test this yourself. Let the pipes cool down and start the boiler. When the steam gets into the system, away from the boiler piping, make a mental note of the time. Now, feel the system return piping near the boiler but not the boiler piping. You should start feeling a temperature difference with in about 15 - 20 minutes.
9. Clean and inspect the existing boiler. This should include a gas pressure check or fuel pump pressure check and combustion analysis.
10. Replace the boiler with a newer steam boiler if the existing boiler is over 10 years old. The older the boiler is the less efficient it is. If the boiler is a coal converted boiler to natural gas or oil this is a must. The large flue passes allows too much heat to leave the boiler and never touch the iron. Therefore, less heat transfer.
