As the temperatures drop in Central Maine, reliability is everything. You rely on your heating system to keep your family warm through our notoriously harsh winters.
If your current boiler is starting to show its age—making strange noises, needing frequent repairs, or causing your energy bills to spike—it might be time to start planning an upgrade.
A new boiler is a significant investment in your home’s comfort and value. But with so many options on the market, it’s not always easy to know where to start. Since 1936, WFC has been helping neighbors in Monmouth and surrounding towns navigate these decisions. Here is a guide to the key factors you should consider when planning your boiler upgrade.
One of the most compelling reasons to upgrade is energy efficiency. Older systems often operate at 60-70% efficiency, meaning nearly a third of the fuel you pay for goes up the chimney rather than into your home.
Today’s high-performance boilers from top brands like Energy Kinetics, Buderus, Viessmann, and Bosch have efficiency ratings approaching or even exceeding 90%. This drastic improvement means that almost every drop of heating oil or propane you burn goes toward its intended purpose: keeping your loved ones warm. In practical terms, replacing an aging boiler can slash your annual fuel costs by 20% or more. Over the lifespan of the unit, these savings often pay for the upgrade itself.
When upgrading, you generally have the choice between sticking with your current fuel source or switching. At WFC, we provide both top-notch heating oil delivery and propane delivery, giving you flexibility based on your preference and budget.
Modern oil boilers are cleaner and more efficient than ever before, while propane offers versatility for other appliances like stoves and dryers. We can help evaluate your property’s setup to determine which fuel source makes the most financial sense for your long-term goals.
A common mistake homeowners make is assuming they should replace their old boiler with one of the exact same size. However, if you’ve added insulation, replaced windows, or built an addition since the last unit was installed, your heating load has likely changed.
An oversized boiler will “short cycle” (turn on and off frequently), leading to wear and tear and wasted fuel. An undersized boiler will struggle to keep up on the coldest January nights. Our professional HVAC team performs a comprehensive evaluation to ensure your new system—whether it’s a Biasi, New Yorker, Rinnai, or NTI model—is sized perfectly for your home’s specific needs.
Even the best equipment needs care to perform at its peak. When selecting a new boiler, consider the maintenance requirements. We proudly install and maintain high-performance boilers that are built to last, but we also emphasize the importance of regular upkeep.
We perform comprehensive annual maintenance to ensure that your boiler’s efficiency stays high and that it runs reliably through the winter. Regular service not only extends the equipment’s lifespan but also keeps your manufacturer’s warranty valid. To make this easier, we encourage homeowners to enroll in one of our affordable heating service plans, which include a complimentary annual tune-up and protection against high repair costs.
The quality of the installation is just as important as the quality of the boiler itself. A top-tier Viessmann or Energy Kinetics boiler won’t deliver its promised efficiency if it’s installed incorrectly.
