Choosing the Best Condensing Boiler

Choosing the Best Condensing Boiler

Choosing the best condensing boiler for your facility will have significant, long-term energy implications. Even so, this purchasing decision is typically undertaken without considering all of the possibilities and options. If you choose the right boiler for your facility, it can continue to meet your facility's needs for decades.

As a result, it's important to consider the suitability of the boiler for your needs as well as operating efficiency. Both of these factors are typically much more important considerations other than the initial cost of the unit. Continue reading to learn more about choosing the best condensing boiler to meet your facility's application and heating needs.

Choosing the Best Condensing Boiler

Condensing boilers have become an important option for industrial facilities, especially for low-temperature and comfort heating process applications. Condensing boilers offer exceptionally high efficiency through the process of recovering the latent heat given off evaporation from boiler exhaust.

With natural gas-fired boilers, this is achieved by utilizing a feedwater return operating at temperatures less than 135° F. In most instances, any returns higher than this temperature will render no benefit through the condensing design.

Develop Seasonal Strategies

Some facilities may only have large hot water or steam requirements for certain times of the year. These types of facilities may only demand a larger boiler operating at low efficiency and low load for the rest of year for applications like water heating. In this case, the large boiler cycles on and off during these periods of low demand, which further reduces efficiency.

For these situations, it may benefit the facility to install a small boiler that allows the larger boiler to seasonally shut down. In many parts of the U.S., especially parts of Texas and California, air quality regulations require the usage of ultra-low NOx burners as well as an aggressive strategy of exhaust gas monitoring.

Lifetime Costs

When choosing the best condensing boiler, it's imperative to choose the right equipment from the beginning. While many boilers have a life expectancy around 30 years, most equipment will last much longer. However, this bolstered lifetime expectancy can only be obtained through regular maintenance.

On the other hand, you may only realize a fraction of this use if the equipment is poorly maintained. In examining the total cost of a standard natural gas-fired boiler over a decade, the costs will break down in some variation of the following:

  • 94% of the total expense of the boiler can be attributed to fuel costs
  • 4% of the total cost of the boiler can be attributed to the initial cost.
  • 2% of the total cost can be attributed to system maintenance and upkeep.

Since the cost of fuel is such a significant factor, it makes dollars and sense to choose the best condensing boiler well-suited to your needs. By properly maintaining the boiler, you will bolster its life expectancy and ensure it continues to perform at peak efficiency with compliant emissions.

Air Quality & Emissions Control

Increasingly, air quality regulations are changing the way industrial boilers operate. Regulations are prompting operators of oil-fired or coal-fired boilers to switch to more environmentally friendly gas-fired replacement boilers.

In the United States in 2012, the Environmental Protection Agency promulgated the legislation entitled the National Emission Standards for Hazardous Pollutants for Major Sources: ICI Boiler MACT (Industrial, Commercial and Institutional Boilers for Process Heaters).

The ICI Boiler MACT prompts facilities to transition to natural gas as the premier fuel of choice.

In many instances, natural gas is the only option for equipment. Fortunately, this legislation came at a time when natural gas production has increased and remains at highly attractive prices. As a result, many of the older gas-fired boilers must be brought up to meet today's more rigorous emission standards.

Changing Requirements

Institutional and industrial steam usage patterns will change over periods of time. While today your boiler may be too small, too large, or function at the wrong pressure or temperature for process requirements, your needs will change.

Today's best condensing boiler packages are available in a vast array of sizes at exceptionally high efficiencies even in the smaller sizes. As a result, many facilities are choosing multiple boilers instead of a single large unit to allow unit redundancy for superior plant reliability. This strategy allows boilers to perform in a more modular fashion, which will keep performance at peak efficiency with varying loads.
