---

### **Pros of the Cleaver-Brooks 853-939**

1. **Reliability and Durability**

The 853 series is known for its robust construction, using high-quality materials and proven combustion technology. Cleaver-Brooks has a long-standing reputation for manufacturing durable boilers that require minimal maintenance over their lifespan.

2. **Efficiency and Compliance**

This model meets or exceeds modern efficiency standards, including those set by the **DOE (Department of Energy)** and **ASHRAE**. It is designed to operate efficiently across a range of loads, reducing fuel consumption compared to older, less optimized boilers.

3. **Modular Design**

The 853-939 can be configured in modular arrangements, allowing for easy expansion or reduction in capacity as demand changes. This flexibility is particularly useful for growing facilities or those with variable heating loads.

4. **Natural Gas Flexibility**

The boiler is designed for **natural gas firing**, which is widely available and generally more cost-effective than oil or propane in many regions. It also supports **dual-fuel capability** (natural gas and oil) in some configurations, providing backup fuel options.

5. **Low NOx Emissions**

The 853 series incorporates **low-NOx burner technology**, helping facilities comply with stricter environmental regulations while reducing operational costs associated with emissions fines.

6. **Automation and Control Options**

Cleaver-Brooks offers advanced control systems, including **modulating burners and digital controls**, which improve system efficiency and ease of operation. Integration with building management systems (BMS) is also possible.

7. **Warranty and Support**

Cleaver-Brooks provides a **standard warranty** (typically 1 2 years on parts, with extended options available) and a strong dealer network for maintenance and repairs. Their technical support is widely regarded as responsive.

8. **Space Efficiency**

The compact design of the 853 series allows for installation in tighter spaces compared to some larger industrial boilers, making it suitable for retrofits or facilities with limited boiler room space.

9. **Fuel Savings Through Modulation**

The boiler s modulating burner adjusts output based on demand, reducing fuel waste compared to on/off cycling boilers. This leads to lower operational costs over time.

10. **Proven Track Record**

Cleaver-Brooks has been a leader in boiler manufacturing for decades, and the 853 series is a well-tested model with a history of reliable performance in commercial and institutional settings.

### **Cons of the Cleaver-Brooks 853-939**

1. **Higher Upfront Cost**

Like many high-efficiency, modular boilers, the 853-939 has a **significant initial purchase and installation cost**. This can be a barrier for smaller businesses or facilities with limited capital budgets.

2. **Complex Installation and Commissioning**

Due to its advanced features (e.g., modulating burners, digital controls), installation requires **skilled technicians**. Poor installation can lead to inefficiencies, malfunctions, or voided warranties.

3. **Maintenance Requirements**

While durable, the boiler requires **regular maintenance** (e.g., burner inspections, heat exchanger cleaning, control system checks) to maintain efficiency and prevent failures. Neglecting maintenance can lead to costly repairs.

4. **Dependence on Natural Gas Supply**

If your facility is in a region with **volatile natural gas prices** or supply concerns, the operating costs could fluctuate unpredictably. Dual-fuel options help mitigate this but add complexity.

5. **Limited Lifespan Compared to Simpler Boilers**

High-efficiency, modular boilers typically have a **lifespan of 20 30 years** with proper maintenance, but they may require **upgrades or part replacements** before older, less sophisticated boilers reach the end of their useful life.

6. **Potential for Higher Operating Costs Initially**

While the boiler is efficient, the **initial energy savings may take time to offset the higher purchase price**, especially if the facility has low heating demands.

7. **Dealer Dependency for Service**

Cleaver-Brooks relies on a network of dealers for service, parts, and support. If there are **few local dealers**, response times for repairs or maintenance could be slower.

8. **Retrofit Challenges**

If the boiler is being installed in an older system, **retrofitting may require additional upgrades** (e.g., piping, controls, or ventilation modifications), increasing costs and complexity.

9. **Noise Levels**

Some users report that the 853 series can be **noisier than expected** during operation, particularly at higher loads. This may be a concern in noise-sensitive environments.

10. **Limited Customization for Extreme Conditions**

While versatile, the 853-939 may not be ideal for **extreme climates** (e.g., very cold regions requiring high-output boilers) or applications with **highly corrosive water conditions** without additional treatment.

---

### **Conclusion**

The **Cleaver-Brooks 853-939** is a **high-quality, efficient, and reliable boiler** well-suited for commercial and institutional applications where **modularity, low NOx emissions, and natural gas efficiency** are priorities. Its advanced features and durability make it a strong choice for facilities planning for long-term operation, provided they can justify the upfront cost and commit to proper maintenance.

However, the **higher initial investment, complexity of installation, and ongoing maintenance needs** may not be ideal for smaller budgets or facilities with limited technical resources. Additionally, its performance depends heavily on **proper installation and operational practices**, which can add to the total cost of ownership.

---

### **Recommendation**

- Your facility requires **modular, high-efficiency heating** with **natural gas flexibility**.

- You prioritize **low NOx emissions** and compliance with environmental regulations.

- You have a **long-term operational horizon** (15 years) and can justify the upfront cost.

- Your facility has **access to skilled technicians** for installation and maintenance.

- You operate in a **stable natural gas market** or have a backup fuel option.

- Your budget is **constrained**, and you can find a **simpler, lower-cost boiler** that meets your basic needs.

- Your facility has **limited space or complex plumbing**, making installation difficult.

- You are in a **region with unreliable natural gas supply** or extreme heating demands.

- You prefer **minimal maintenance** and are willing to accept slightly lower efficiency.

For facilities where **efficiency, reliability, and long-term performance** are critical, the **853-939 is an excellent choice**.
