College Park, Maryland, home to the University of Maryland and a mix of older homes and student housing, sees its share of chilly winters. While many modern buildings use forced-air systems, boilers remain common in older residences and multi-unit properties across neighborhoods like Old Town, Calvert Hills, and Berwyn.
For homeowners and property managers alike, understanding how boilers work, how to spot issues early, and what maintenance steps are essential can prevent unexpected breakdowns and costly repairs—especially during the colder months.
Why Boilers Are Still Used in College Park
In areas like College Park, where many homes were built in the mid-20th century, boiler systems remain a popular heating choice due to their:
Even, radiant heat distribution without blowing air
Quiet operation, ideal for residential neighborhoods
Long system lifespan, often exceeding 20 years with proper maintenance
Improved air quality, with no dust or allergens circulated through ducts
Boilers are particularly useful in older homes and multi-level properties, where they provide a more consistent and comfortable heating experience during Maryland’s winter season, which typically lasts from November through March.
How a Boiler System Works
Boilers function by heating water and circulating it through a closed system of pipes, delivering warmth to radiators, baseboards, or radiant floor systems. The water then returns to the boiler to be reheated and recirculated. Some College Park homes use steam boilers, while others use hot water models.
Unlike furnaces, boilers do not rely on ductwork or fans, making them ideal for homes with minimal renovation or retrofitting space.
Common Boiler Problems in College Park Homes
Over time, boilers can develop issues due to age, wear, or lack of maintenance. In College Park—especially in rental units and older homes—these are some of the most frequently reported problems:
1. No Heat or Hot Water
This can stem from thermostat failure, broken motorized valves, low pressure, or a damaged diaphragm.
2. Leaking or Dripping Boiler
Leaks are often caused by corrosion, pressure problems, or worn-out internal components. This is especially common in systems that haven’t been serviced regularly.
3. Unusual Noises (Whistling, Gurgling, or Banging)
Known as “kettling,” these noises often indicate limescale or sludge buildup inside the heat exchanger—an issue seen in homes with older plumbing or untreated water.
4. Pilot Light Keeps Going Out
This can be caused by a broken thermocouple or a faulty gas valve—issues that require prompt attention for safety reasons.
5. Radiators Not Heating Evenly
Air pockets or sediment buildup can block water flow, resulting in cold spots or ineffective heating.
Seasonal Boiler Maintenance Tips for College Park Residents
Given the local weather and older housing stock in areas like Lakeland and North College Park, it’s critical to keep your boiler system in good shape. Regular maintenance can extend system life and reduce energy bills.
Here are key maintenance practices:
Bleed radiators at the start of each heating season
Check system pressure monthly (should usually be between 1.0 and 1.5 bar)
Flush the system every few years to remove sediment buildup
Inspect pipes and joints for leaks, rust, or corrosion
Schedule a professional boiler inspection annually
If you're a landlord in College Park, especially with student tenants, this kind of routine care is crucial to avoiding mid-semester heating emergencies.
When to Consider Replacement
While this article focuses on repairs, some boilers reach a point where replacement is more cost-effective. Consider a replacement if:
The system is over 20 years old
It breaks down frequently or repairs are adding up
It has a low energy efficiency rating
Replacement parts are no longer readily available
Still, most boilers can perform well past their expected lifespan with consistent maintenance and timely repairs.
Final Thoughts
Boiler systems remain an important part of the heating infrastructure in College Park, MD, especially in older homes and student housing. By understanding how your system works and staying ahead of repairs, you can ensure reliable heat throughout the winter.
Whether you live near Paint Branch Parkway, along Route 1, or in College Park Woods, having a solid understanding of boiler maintenance can help you avoid the hassle of breakdowns and high repair costs.
