Boiler Installation & Replacement in Overland
Choosing a new boiler or replacing an aging one is a significant decision for any homeowner. Several factors indicate it might be time for a Boiler Replacement:
- Age: Boilers typically have a lifespan of 15-20 years. If your boiler is 20 years old or older, it's likely operating at significantly lower efficiency than modern units and may be prone to frequent, expensive repairs. While repairs might seem like a short-term fix, the cumulative cost can quickly outweigh the investment in a new, reliable system.
- Frequent Breakdowns: If your boiler requires multiple repairs each heating season, it's a clear sign it's nearing the end of its useful life.
- High Energy Bills: Older boilers are far less energy-efficient. A noticeable increase in your gas bill could indicate your boiler is wasting energy.
- Inconsistent Heating: Cold spots in your home or radiators that don't heat up properly suggest your boiler is no longer distributing heat effectively.
Investing in a new boiler offers numerous benefits, including improved energy efficiency, lower heating costs, consistent and reliable warmth, and enhanced safety features. When you choose Hely Heating for a Boiler Installation in Overland, we guide you through the process, helping you select the right system for your home's size, heating needs, and budget.
We focus on installing high-quality gas boilers, including those with 80% AFUE (Annual Fuel Utilization Efficiency) and higher. AFUE measures how efficiently a boiler converts fuel into heating energy. A higher AFUE rating means the boiler uses less fuel to produce the same amount of heat, directly translating into lower energy bills and reduced environmental impact for your Overland home. Modern boilers are designed to work seamlessly with hot water radiator systems, providing consistent, comfortable heat throughout your property. We ensure your new boiler is installed correctly and optimized for performance, maximizing its lifespan and efficiency.
Boiler Maintenance
Regular maintenance is the best way to keep your boiler running efficiently and reliably year after year. An annual boiler tune-up can help identify potential issues before they cause a breakdown, improve energy efficiency, extend the lifespan of your system, and ensure it operates safely. Our Maintenance Plan includes seasonal check-ups for your heating and cooling systems, providing peace of mind and preventing unexpected problems.

Boilers and Hot Water Radiator Systems
Many homes in Overland feature classic hot water radiator heating systems. These systems provide a unique, even, and quiet form of heat. Boilers are specifically designed to work with these systems, heating water that circulates through pipes to the radiators. Our technicians have extensive experience servicing, repairing, and installing boilers that are specifically compatible with and optimized for hot water radiator systems. We understand the nuances of maintaining these systems to ensure efficient heat distribution throughout your entire home.
Understanding Boiler Efficiency (AFUE)
As mentioned, AFUE is a critical factor when considering a new boiler. It represents the percentage of fuel that is converted into usable heat over the course of a typical year. An older boiler might have an AFUE rating significantly below 80%. By upgrading to a gas boiler with 80% AFUE or higher, you ensure that a greater portion of the fuel you pay for is actually used to heat your home, rather than being lost through the chimney or exhaust. This increased efficiency is not only better for your wallet but also contributes to lower energy consumption. We help you understand the AFUE ratings and choose a boiler that meets your efficiency goals and provides reliable heat.

Addressing Common Boiler Questions
Overland homeowners often have questions when considering boiler services. Here are answers to some common inquiries:
Is it worth replacing a boiler that is 20 years old?
In most cases, yes. A boiler of this age has likely outlived its expected lifespan. While repairs are possible, they often become more frequent and costly as components age. A new boiler offers significant improvements in energy efficiency (saving you money on utility bills), increased reliability, and peace of mind with a new warranty. The long-term savings and reduced hassle often make replacement a more economical and practical choice than continuing to repair an aging unit.
What's the cost difference between a boiler and a furnace?
Boilers and furnaces are different types of heating systems designed for different heat distribution methods. Furnaces heat air and distribute it via ductwork, while boilers heat water for systems like hot water radiators or radiant floors. The initial cost can vary based on type, size, and efficiency. It's not a simple comparison of furnace price vs. boiler price, as they serve fundamentally different home heating infrastructures.
How much does it cost to repair a boiler?
The cost of a boiler repair varies greatly depending on the nature and severity of the problem, the age of the boiler, and the cost of replacement parts. Minor issues like a faulty ignitor might be less expensive than major repairs involving heat exchangers or circulation pumps. The best way to determine the cost is to have a qualified technician diagnose the specific issue affecting your Overland home's boiler.
