Temple Hills, Maryland, located just minutes from Washington D.C., is a diverse suburban community with a mix of older homes, townhouses, and multifamily units. Many of these properties still rely on boiler systems for heat, especially during the colder months. Whether you're a long-time homeowner near Camp Springs, or a landlord managing a duplex off St. Barnabas Road, understanding how boilers work—and how to maintain or troubleshoot them—can save time, money, and stress.
This article covers what Temple Hills residents should know about boiler systems, common issues, and smart maintenance practices.
Why Boilers Are Still Common in Temple Hills Homes
Although modern HVAC systems are common in new builds, many homes in Temple Hills—particularly those built between the 1950s and 1980s—use hot water or steam boilers for heating. These systems are valued for:
Even, consistent warmth throughout the home
Quiet operation compared to forced-air systems
Better air quality (no dust or allergens blown around)
Durability, often lasting 15–30 years when maintained properly
Given Maryland's long heating season, boiler systems remain a practical and efficient choice in many Temple Hills properties.
How a Boiler System Works
A boiler heats water, then distributes it as either hot water or steam through pipes and radiators. Once the heat is delivered, the water returns to the boiler to be reheated, forming a closed loop. This is different from furnaces, which heat air and push it through ducts.
In Temple Hills, where winter temperatures can dip into the 20s and 30s, especially from November through March, these systems often run daily during peak heating season.
Common Boiler Problems in Temple Hills, MD
Homes in Temple Hills—especially older ones—often experience a handful of boiler-related issues. Here are some of the most common problems:
1. No Heat or Hot Water
This can be caused by a malfunctioning thermostat, low water levels, or a broken motorized valve or circulation pump.
2. Strange Noises (Banging, Whistling, or Gurgling)
Also known as “kettling,” these noises are often the result of mineral deposits or air trapped in the system—both common in Maryland’s moderate-hard water zones.
3. Leaking or Dripping
Boiler leaks can stem from worn seals, corroded pipes, or pressure issues. Even small leaks should be taken seriously to avoid long-term water damage.
4. Low Boiler Pressure
A drop in boiler pressure affects heating performance. It’s often caused by water leaks or bleeding radiators and may require re-pressurizing the system.
5. Pilot Light Keeps Going Out
Older boiler models in Temple Hills homes may use a standing pilot light, which can go out due to drafts, faulty thermocouples, or gas supply issues.
Why Preventive Maintenance Matters in Temple Hills
Many Temple Hills homes have aging infrastructure, and regular boiler maintenance is crucial—especially when cold weather hits. Routine maintenance helps ensure your system runs efficiently and can prevent emergency repairs.
Recommended annual tasks include:
Flushing the boiler to remove sediment or limescale buildup
Bleeding radiators to eliminate trapped air
Checking boiler pressure and topping up as needed
Inspecting for signs of corrosion or wear
Testing thermostats, valves, and safety controls
For landlords or homeowners with multi-unit properties, these steps are especially important to avoid tenant complaints and higher utility costs.
Special Considerations for Older Homes in Temple Hills
Homes in neighborhoods like Hillcrest Heights or Marlow Heights often have older plumbing and boiler systems. If your home was built before 1980, you should also look for:
Outdated expansion tanks that no longer maintain proper pressure
Uninsulated piping, which can lead to heat loss
Original radiators that may be partially clogged with sludge or rust
Asbestos insulation around older boiler components (must be handled professionally)
When Is Boiler Replacement Better Than Repair?
While this article focuses on repair, it’s helpful to recognize when a boiler is nearing the end of its life. Consider replacing your boiler if:
It’s over 20 years old and frequently breaks down
You notice rising utility bills with no change in usage
Replacement parts are hard to find
You’re looking to improve energy efficiency and reduce maintenance
That said, many Temple Hills boilers can last for decades with basic upkeep and occasional repairs.
Final Thoughts
Boilers remain a reliable and efficient way to heat homes in Temple Hills, Maryland. Understanding how your system works—and staying alert to early warning signs—can help you avoid bigger issues during the winter months.
Whether you're located near Branch Avenue, Iverson Mall, or tucked in a quiet cul-de-sac, taking a proactive approach to boiler care will keep your property warm, safe, and energy-efficient for years to come.
