Steam Boiler

Steam boilers are a type of low pressured units that are used for heating homes and large businesses. These are designed to be vented by a natural draft through the use of a line masonry or metal chimney system. In order to function it must use a large amount of air for combustion, ventilation, and dilution of flue gases that are available inside of the room. Most models will cost around $4,500.


  • Spill switch to find problems with venting
  • Rollout switch to find blockages in heat exchanger
  • ASME pop safety valve
  • Cast iron heat exchanger
  • Stainless steel burners
  • Fiberglass insulation to prevent heat loss
  • Aluminized steel and corrosion resistant base and flue
  • Draft diverter that allows it to be installed in low spaces

Clean Steam Boilers

These units are able to work for years without any problems as long as they are cleaned every few months. Without the proper maintenance corrosion will wear the metal down and cause leaks or will break certain parts of it.

The first thing you need to do when cleaning the steam boiler is to pour trisodium phosphate into the unit. This is a popular cleaning agent used for boilers. You must add one pound of it for every fifty gallons of water that is inside of the unit. You can also use MEX, sodium carbonate, and sodium hydroxide.

Turn the heat on the boiler until it reaches one hundred and eight degrees Fahrenheit. Keep it at this heat for two hours. During this time make sure that no steam is being produced. Water does not boil until it reaches two hundred and twelve degrees Fahrenheit so this shouldn’t be a problem.

Drain the boiler after two hours and refill it. Make sure that the pH levels are set between 7.0 and 8.5.
