Lennox® Boiler FAQs
Straightforward answers to the most common hydronic questions our Upstate New York customers ask when selecting a new boiler.
Why is my boiler losing water pressure?
Usually a small weeping leak in radiator piping or valves, or a water-logged expansion tank bladder. Persistent pressure loss deserves prompt attention before cold dry-firing damages the cast-iron heat exchanger. Appolo technicians can diagnose and balance pressure in one visit.
What is the difference between Lennox GWB84-IE and GWB84-E Units?
The GWB84-IE features an induced-draft fan that mechanically pushes exhaust gases outside, making it ideal for homes with chimney draft restrictions. The GWB84-E is a standard chimney-vented boiler designed as a direct drop-in replacement into healthy existing masonry chimneys without electrical exhaust fan requirements.
How often should a hydronic boiler be serviced?
Hydronic heating systems must be serviced annually before the cold season. Cleaning the burners, testing the low-water cutoff safety control, and testing expansion tank charge keeps efficiency high and protects both the cast-iron assembly and your home.
Are there utility rebates available for boiler upgrades?
Yes! New York utilities like National Grid and Central Hudson, along with NYSERDA programs, frequently offer instant or mail-in rebates for qualifying high-efficiency boiler installations. Appolo Heating assists with all paperwork to maximize your return.
