#### **Cons**

1. **Higher Upfront Cost**

The PBN2001-M9 is **more expensive to purchase and install** than traditional cast iron or basic condensing boilers. The premium price reflects its advanced technology, but it may not be justified for homeowners on a tight budget.

2. **Installation Complexity**

Condensing boilers require **proper venting and drainage systems** to handle condensate. If your home lacks the necessary **PVC drain lines and sealed combustion air supply**, additional modifications may be needed, increasing installation costs.

3. **Limited Fuel Flexibility (Natural Gas Focus)**

While the PBN2001-M9 is primarily designed for **natural gas**, it may not be as efficient or compatible with **propane or oil** without additional conversions. If you re in a region with limited gas access, this could be a drawback.

4. **Potential Condensate Drain Issues**

Condensing boilers produce **water condensate**, which must be properly drained. If the drainage system is not installed correctly, **leaks or freezing** can occur in colder climates, leading to maintenance headaches.

5. **Dependence on Water Quality**

While the stainless steel heat exchanger resists corrosion, **hard water can still cause mineral buildup** over time. Regular **descaling and maintenance** are necessary to prevent reduced efficiency.

6. **Limited Availability of Parts and Service**

Lochinvar is a reputable brand, but **parts and certified technicians** may be harder to find in some rural or less developed areas. Ensuring long-term serviceability is important before purchase.

7. **Not Ideal for Very Large Homes (Without Upgrades)**

The PBN2001-M9 is a **medium-sized boiler (200,000 BTU input)**, which may not be sufficient for **very large homes or those with extreme heating demands**. A **larger model (e.g., PBN3000 series)** or **multiple boilers in a cascade system** might be needed.

8. **Potential Learning Curve for Installation**

If your HVAC contractor is not experienced with **condensing boilers or hydronic systems**, they may struggle with proper setup, leading to inefficiencies or warranty issues.
