No component is more critical in hydronic heating than the boiler. Whether working on a residential retrofit, a new commercial build, or a light commercial replacement, choosing the right unit can improve the system’s efficiency, reliability, and longevity.
At Sales, Marketing & Service, Inc. (SMS), we support plumbing and HVAC contractors across New England by helping them specify the best products for every job. With years of experience representing top boiler manufacturers, we know how to help you avoid common mistakes and ensure your next install goes smoothly.
Boiler Selection Basics: 5 Key Factors to Consider
- Proper Sizing
Oversizing a boiler may seem safe, but it can lead to short-cycling, reduced lifespan, and higher fuel bills. SMS can help you size your boiler based on accurate heat load calculations, not guesswork. - System Type Compatibility
Is the system hot water or steam? High-temp baseboard or radiant floor heat? Condensing boilers offer excellent efficiency, but only when matched to the correct system return temperatures. We’ll help you choose the best model for the application. - Venting & Fuel Type
Ensure the selected boiler works with your jobsite’s available fuel (gas, propane, or oil) and that the venting method matches site conditions. SMS will help you check clearances, flue material, and venting codes before installation day. - Control Integration
Many modern boilers have built-in smart logic or require external control packages. We’ll confirm that your selection works with your zoning setup or building automation system and help you choose matched accessories if needed. - Long-Term Serviceability
Contractors often face service calls on units they didn’t install. We help you spec efficient boilers, easy to maintain, and supported by accessible parts and strong warranties.
Common Pitfalls to Avoid
- Choosing a condensing boiler for a high-temp system
- Skipping water quality requirements or treatment steps
- Ignoring the vent length or clearance specs
- Forgetting to verify DHW needs (combi vs. dedicated tank)
- Going it alone without confirming specs with the rep
