Popular Pennco Boiler Models Reviewed
Pennco 15 Series Boiler
The 15 Series is a compact, budget-friendly boiler that offers 82% to 85% AFUE efficiency with gas or oil fuel. It’s ideal for smaller homes and easy to install in utility closets or basements. Homeowners often cite its quiet operation and minimal maintenance as strengths. However, it lacks advanced controls for zone systems.
Pennco 16 Series Boiler
This model offers an 84% AFUE rating and is known for reliability and electronic ignition. It comes with flexible venting, allowing for both natural and power-vent options. It is a popular choice among mid-sized homeowners who value straightforward performance over frills.
Pennco 30B Series Boiler
The 30B’s 85% efficiency and atmospheric venting make it suitable for retrofits or light commercial applications. Its higher output options (up to 299 MBH) are praised for large homes or small apartment buildings. Users highlight its ease of repair but note it is less efficient than condensing models.
Pennco Keystone KSWB Series (Condensing, Wall Hung)
Engineered for efficiency, the KSWB series delivers a remarkable 95% AFUE, qualifying for many utility rebates. It’s a wall-hung, space-saving design with a stainless-steel heat exchanger and modulating gas burner for precise comfort. It stands out for low operating costs, whisper-quiet function, and modern controls but typically costs more upfront.
Installation Guidelines And Best Practices
Professional installation is crucial for Pennco boilers to ensure optimal efficiency, safe operation, and full warranty coverage. Installers must size the boiler based on home heat loss calculations—not just previous equipment output.
- Proper Sizing: Avoid oversizing, which leads to short cycling and wasted energy.
- Venting Requirements: Follow the manufacturer’s venting guide for each series—direct vent, power vent, or standard chimney-sidewall setups.
- Condensate Drainage (For Condensing Models): Install correct drains and neutralizers to manage acidic condensate.
- System Controls: Set up compatible outdoor reset controllers or thermostats for efficient heating cycles.
- Permits And Inspections: Ensure compliance with local codes, which often require inspection by a city or county official.
Pennco offers a limited warranty—generally 10 years on heat exchangers and one to five years on other components depending on the model. Always register the boiler post-installation for full coverage.

Efficiency Ratings And Cost Savings
The Annual Fuel Utilization Efficiency (AFUE) rating measures a boiler’s fuel-to-heat conversion. Pennco models span from about 82% (basic cast iron) to 95% (condensing). Higher AFUE means less wasted energy—translating to lower utility bills. Condensing Keystone series models increase efficiency by reclaiming heat from exhaust gases.
| Model | AFUE Efficiency | Estimated Annual Fuel Savings* |
|---|---|---|
| 15 Series (Standard) | 82% | $300 vs. older, 70% efficiency boiler |
| Keystone KSWB (Condensing) | 95% | $600+ vs. older, 70% efficiency boiler |
*Estimated annual savings based on 1,500 sq. ft. home in Northern U.S., actual savings vary.
While the upfront investment is more for high-efficiency boilers, utility rebates and lower energy costs can offset the price within several years.
User Reviews And Customer Satisfaction
Most Pennco boiler owners highlight durability, straightforward maintenance, and quiet operation as major benefits. Many praise the ease of finding replacement parts and the competence of Pennco’s customer support. These boilers have a reputation for lasting over 20 years when properly maintained.
Some negative reviews relate to inexperienced installer errors causing maintenance issues, emphasizing the need for certified HVAC technicians. Others note that entry-level models (like the 15 Series) lack advanced controls, which may limit zoning options in larger homes.
- Positive Feedback: Reliable comfort, reasonable price, longevity.
- Criticisms: Basic control interface on lower-priced models; not as high-tech as European competitors; variable warranty terms.

Common Issues And Troubleshooting
Pennco boilers are generally low-maintenance, but like all boilers, they may face common issues over decades of use. Homeowners report:
- No Heat/Low Heat: Check the thermostat, circulator pump, and water level. Air in the lines can also reduce output—professional bleeding is recommended.
- Pilot Light Or Ignition Failures: Most Pennco models have electronic ignition; if not firing, check the fuse, flame sensor, or gas valve.
- Leaking: Look for failed gaskets, pressure valves, or corrosion near joints. Older cast iron may develop rust over time if maintenance is ignored.
- Noisy Operation: May be due to mineral buildup (“boiler kettling”) or trapped air. Have a professional flush the system annually.
Routine servicing and water quality checks prevent most issues and protect the heat exchanger for the long term.
Maintenance Tips For Long Pennco Boiler Life
- Annual Professional Inspection: Schedule check-ups each fall for cleaning, safety checks, and component assessment.
- Water Quality: Use corrosion inhibitors and test pH if you have hard water or an old iron system.
- System Flushing: Remove mineral deposits every few years to prevent kettling and maintain efficiency.
- Gasket And Valve Checks: Inspect for signs of leaks, cracks, or pressure fluctuations.
- Keep Vents Clear: Ensure external vents and combustion air intakes are unobstructed.
Regular care ensures a Pennco boiler can last two decades or more—maximizing your original investment.
