The Top Features Offered on Today’s Most Efficient Boiler Are Remarkable

Best Boilers

When choosing the most efficient boiler for your facility, it's vital to choose one that meets the current needs of the facility while delivering optimum efficiency. A boiler system must be able to meet the building's peak hot water demand as well as heating demand. At the same time, the boiler should be able to operate at an efficient level on part-load conditions.

Selecting a high efficiency boiler system and properly sizing it requires an adequate amount of knowledge on both the load profile and peak demand. If the building loads are variable, designers and engineers may find ample benefits in considering the installation of smaller modular boilers in addition to high efficiency boilers with modulating burners.

In periods of low demand, certain boilers can be isolated and avoid cycling losses and standby losses. The most efficient boilers can also be staged, so every boiler is operating at high efficiency without having to go through an extra cycle.

Today's boilers are more advanced than ever and include a variety of cutting-edge operating functions. With so many features available, it's highly advantageous for you to have an understanding of the features that have a direct impact on efficiency. Continue reading to learn the top features offered on today's most efficient boilers.

Water Temperature Reset

Any high efficiency boiler should come with the ability for water temperature reset. This feature involves the temperature of the return water or the outdoor air temperature. The supply water is set to a lower temperature whenever the heating load is reduced.

Low Mass

Through the typical use of the boiler, it will naturally cycle on and off. When a boiler has high mass, it will take significantly longer to bring the temperature up to operating temperature. On the other hand, low-mass boilers reduce the consumption of energy. These boilers are able to be brought online quicker, which avoids the need to have another boiler on standby.

Hybrid Systems

While condensing boilers are significantly much more efficient with part-load conditions, conventional boilers operate more efficiently under full-load conditions. Hybrid systems allow you to enjoy the best of both worlds by switching between operating controls based on optimum conditions. Hybrid systems can be retrofitted for applications when new condensing boilers are integrated into a conventional boiler system.

Modulating Burners

The majority of today's most efficient boilers should be able to alter its heating output through burner modulation. Because most boilers will operate at part load, a modulating burner will intuitively vary the strength or tone of the flame. This process boosts efficiency and avoids needless cycling on and off.

For gas-fired, hot-water boilers, a minimum turndown ratio is 4:1 is suggested. Modulating burners are extra important with condensing boilers that are required to operate at high efficiency for part load.

Exact Fuel-Air Ratio Control

It's vital to keep fuel-air ratio at the proper levels at full-load operation and part-load operation. This goal is accomplished through the use of sensor-driven servos instead of mechanical linkage between the blower damper and gas input.

For larger boilers, oxygen trim applications should be used. These systems are designed to carefully monitor oxygen in the flue gas and adjust the fuel-air ratio for maximum efficiency of combustion.

Optimum Start Control

Optimum start controllers are designed to alter the start of the building's heating system. These start times will depend on the amount of heat retained in the building and the weather. For instance, in warmer weather the boiler's start time would be delayed, which would save a significant amount of energy. The goal of optimum start control is to fire up the boiler in a manner that coincides with the time building will become occupied.

Additional Boiler Enhancements

Today's most efficient boilers include a variety of additional enhancements to bolster the performance and energy efficiency of the system. Some of these features include:

  • Remote monitoring capability
  • Using electronic ignition devices
  • Reusing heat from blowdown
  • Reusing heat from return condensate with steam boilers
  • Increasing boiler insulation
  • Bolstering piping insulation

Tips to Maximize Your High Efficiency Boiler

When it comes to using the most efficient boiler, it's vital to conduct regular maintenance and diagnostic procedures. These simple steps will help to quickly detect operating problems as well as any other efficiency problems. Some of the most common practices include:

  • Regular inspection of water levels because low levels can actually damage the boiler.
  • Utilizing an oxygen trim sensor to maintain steady excess air levels. This will ensure the burners mix fuel and air properly.
  • Have water treatment to increase efficiency and prolong the life of the unit.
  • Ensure fireside and waterside surfaces are cleaned annually.
