Gas-fired, high-efficiency boilers are becoming increasingly popular in U.S. homes. And for good reason! Traditional boilers tend to waste a significant amount of energy because the combustion hot gases are vented directly out of the boiler’s flue. On the other hand, gas-fired, high-efficiency boilers are designed to capture more of this heat and transfer it throughout the home’s heating system, reducing energy consumption and lowering heating bills. Gas-fired, high-efficiency boilers utilize condensing technology, which incorporates a secondary heat exchanger to recapture the combustion gases and extract additional heat. This process significantly increases the overall efficiency of the system and we’re here for it!
When it comes to ensuring the performance, energy efficiency and longevity of this popular heating appliance, maintenance is critical. Here are three things that you should know about maintaining a gas-fired, high-efficiency boiler.
Prioritize annual boiler servicing by calling a qualified service technician
First and foremost, call a professional service technician and schedule annual maintenance. We’re serious—get this service appointment on the books. A certified technician will inspect, clean and tune the boiler to ensure efficient combustion and safe operation. During routine maintenance, a technician will be able to catch one often overlooked item: acidic condensate. This residue is the byproduct of the condensing technology used in gas-fired, high-efficiency boilers. If left untreated, acidic condensate can damage plumbing, concrete foundations, floor drains, septic systems and other wastewater infrastructure. But not to worry. Filtration devices called condensate neutralizers are purpose-built specifically for these heating appliances to prevent such damage.
Like the high-efficiency boiler, the condensate neutralization device also needs to be routinely serviced to ensure continued protection and code compliance. In doing so, homeowners can mitigate the risk of expensive property damage. A professional service technician, who is trained to handle heating and plumbing equipment, will be able to test the pH of the treated condensate leaving the filtration device and will then replace the neutralizing media when needed. This routine neutralizer maintenance should happen once a year, ideally, when the boiler maintenance is performed.
Monitor and adjust boiler settings for optimal efficiency
In addition to having your gas-fired, high-efficiency boiler serviced annually, it’s also important to have your service technician review the boiler’s control settings. Some high-efficiency boilers have advanced controls that allow for programming and adjustments. Understanding how to optimize these settings can contribute to increased energy efficiency.
It’s also important to keep a close eye on fuel consumption and your monthly heating bill. If you notice a sudden increase in fuel usage or a higher-than-normal bill, it could be a sign of an issue with the boiler. Addressing problems promptly can prevent further damage and maintain optimal performance.
Proactively address water quality issues
High-efficiency boilers are sensitive to water quality. Mineral deposits and impurities in the water can lead to scale buildup in the heat exchanger, reducing the boiler’s efficiency. Consider water treatment measures such as installing a water softener or using water treatment chemicals to prevent scale formation.
It’s also a good idea to periodically flush the boiler system to remove accumulated sediments and debris. Regular flushing helps maintain optimal water quality and prevents the buildup of impurities that can negatively impact the boiler's performance.
