The Importance of Water Treatment for Commercial Boilers

It’s winter in New Hampshire and you couldn’t pick a worse time for your commercial boiler system to call it quits. The best way to keep your commercial boiler running properly is to treat your feedwater, the water that circulates within your system. Secondwind Water Systems offers water treatment for commercial boilers operated by commercial property owners and industrial and manufacturing facilities.

“If your water isn’t treated, your boiler will likely have problems within its first year of installation,” explains Steve Guercia, commercial and public water systems manager at Secondwind Water Systems. Common symptoms include:

  • Overheating
  • Failure to produce hot water or steam
  • Reduction in boiler flow rate
  • Overall loss of efficiency

“The untreated water that runs through your boiler is going to decrease its operating efficiency and ultimately, shorten its lifespan,” Guercia adds. This is why water treatment for commercial boilers is so critical.

How Untreated Water Damages Commercial Boiler Systems

If you have a commercial boiler with untreated feedwatereven municipal wateryour system will not operate efficiently. Untreated feedwater typically contains dissolved solids, dissolved gases, and metal solids, which cause commercial boiler system damage and break down.

1. Dissolved Solids

As the feedwater is heated, dissolved solids form scale on heat transfer surfaces. These scale deposits will drastically reduce your boiler’s heat transfer capability, which leads to overheating, low steam volume, tube failure, and efficiency loss.

2. Dissolved Gases

Dissolved gasessuch as carbon dioxide and oxygencorrode your boiler piping system and internal components.  “If these corrosive gases are not removed from your feedwater, they will eventually eat through your boiler tubes, causing leaks and eventually, equipment failure,” Guercia explains.

3. Metal Solids

Metal solids, including calcium bicarbonates, magnesium, chlorides, and sulphur, cause water hardness. The biggest contributors to hard water are calcium and magnesium, which cause scale deposits. These calcium and magnesium deposits build-up overtime, eventually plugging pipes and boiler tubes. The end result is a significant reduction in heat distribution through the entire boiler system. This heat distribution inefficiency leads to wasted fuel, an overworked system, and ultimately, boiler failure.
