Features

• Spacious cabinet allows full access to all critical parts that are strategically positioned
• Durable, high-grade stainless steel firetube primary heat exchanger maximizes heat transfer, and its vertical design promotes self-rinsing during operation
• Corrosion-resistant polypropylene heat exchanger base protects against acidic condensate
• Sound-dampening air silencer for whisper-quiet operation
• Insulated heat exchanger and DHW pipes further reduce heat loss and noise
• Sealed cabinet preheats incoming air for smooth starting, and does not pull any potential outside debris directly into blower and burner
• Removable, unique control terminal blocks eliminate potential field wiring errors
• Built-in, variable speed ECM circulator saves electrical energy and installation time
• 3-in-1 universal air and vent adapters readily accept different types of pipe materials along with built-in test ports to aid combustion testing

What Our Experts Think

• High‑efficiency condensing design: The Weil‑McLain ECO‑Tec 110‑H 110,000 BTU Heat‑Only Condensing Gas Boiler delivers strong energy savings by capturing extra heat from exhaust gases, boosting efficiency compared to traditional boilers.

• Heat‑only focus: Designed exclusively for space heating, this model pairs well with separate domestic hot‑water systems or indirect tanks.

• Quiet, reliable operation: Smooth combustion and advanced controls provide consistent hydronic heat with low operational noise and dependable performance.

• Durable construction: Engineered for long service life with corrosion‑resistant heat exchangers and service‑accessible components — a solid choice for homes or light commercial systems.

Product Q&A

• What does “heat‑only” mean?
  It only provides space heating — domestic hot water is handled by a separate water heater or indirect tank.

• What fuel does it use?
  Natural gas; propane conversion kits are available through qualified technicians if needed.

• What heating distribution systems work with this?
  Compatible with hydronic baseboards, radiant floor systems, and fan coils tied into a hot‑water loop.

• Is this high efficiency?
  Yes — condensing technology extracts more heat from the combustion process, increasing efficiency and lowering fuel costs.

Maintenance Tips

• Annual professional service: Have a licensed HVAC technician inspect and tune the boiler before each heating season — checking burner, heat exchanger, and controls.

• Check condensate drain: Ensure condensate lines and traps remain clear and properly pitched to avoid clogs or freeze issues.

• Monitor pressure & water level: Maintain correct boiler pressure and expansion tank condition.

• Clean intake & exhaust terminations: Keep vent openings and combustion air paths free of debris and obstruction.

• Inspect for leaks: Periodically check around valves, fittings, and piping for signs of water or gas leaks.

• Water quality: Use recommended corrosion inhibitors and schedule periodic flushing to reduce scale and preserve efficiency.
