The Pros and Cons of a Low-Water, Low-Mass Boiler

If you are thinking about getting a low-water, low-mass boiler, you need to think carefully about whether this is the right option for you. Keep in mind that the right option for one company may not match the needs of your company. If you’re considering a low-water, low-mass boiler, we challenge you to ask yourself, “Do the pros of something new and compact outweigh something reliable and consistent”? It would help if you compared the benefits and drawbacks of a low-water, low-mass boiler to a gold-standard boiler. There are several key points you should keep in mind.

The Advantages of a Low-Water, Low-Mass Boiler

There are several advantages of going with a low-mass boiler. These include: 

  • Short Term Costs: If you are concerned about the amount of money you will spend on your boiler, you may want to take a closer look at this option. The equipment is usually less expensive, allowing you to reduce your overhead expenses.
  • Requires Less Space: If the facility your boiler will be operating from is small, a low-water, low-mass boiler could be the best option for your business, as they are a fraction of the size of a gold-standard boiler. 
  • Great for Small Batch Increments: Low-water, low-mass boilers are a great option if you are using them in small batches and turning the systems off/online frequently. 
  • Shorter Learning Curve: A smaller boiler usually has a shorter learning curve. If you are concerned about teaching your employees how to use a boiler properly, you may want to go with this option. 

The Disadvantages of a Low-Water, Low-Mass Boiler

There are a few significant disadvantages of using this type of boiler system as well. A few points you should keep in mind include: 

  • Long Term Costs: Low-water, low-mass boilers require constant maintenance. Even though this boiler system may save you money during the initial installation, it is much more expensive to repair. If the system isn’t operating efficiently, minerals can build up in the tubes causing them to rupture. Repairing or potentially rebuilding a low-water, low-mass boiler comes with a hefty price tag. 
  • Unable to Modulate and Maintain Pressure for Long Periods of Time: Unlike our gold-standard boilers, low-water, low-mass boilers are unable to create a low fire rate while maintaining production levels. If you are in need of a boiler that stays on consistently for long periods of time, the amount of energy needed for a low-water, low-mass boiler to keep up with a gold-standard boiler will be much higher. 
  • High Minimum Flow Requirements: In order for the boiler to work properly, you need to meet the minimum flow requirement. In a smaller boiler system, this minimum flow is higher, which can increase your expenses.
  • High Water Side Pressure Drop: Another major disadvantage is a high water side pressure drop. This significant pressure difference could increase the stress on the system, making potential repairs more likely. 
  • More Sensitive to Water Quality: You need to closely monitor your water quality, including the ph and hardness. A smaller boiler system is more sensitive even to small changes in your water quality. 

You should keep these points in mind when trying to figure out if this boiler system is right for you.
