On January 1, 2026, Con Edison's $2.1 billion energy efficiency and building electrification program went into effect, authorized by the NY Public Service Commission for 2026-2030.

The mandate is clear: Electric utilities must spend 67% of their non-LMI efficiency budgets on building electrification. Heat pumps are the primary beneficiary.
"Energy efficiency is a go-to resource, is the first step to decarbonizing the buildings sector and will drive longer-term energy burden reductions for lower-income New Yorkers."
Con Ed pays for heat pump installation. They do not pay for long-term maintenance. The efficiency numbers on the box assume clean equipment—but scale doesn't wait.
Heat pumps are 3-4x more efficient than fossil fuel systems—when clean. Every heat pump relies on heat exchangers to transfer thermal energy. These surfaces are vulnerable to mineral scale.
1/16" 12% efficiency loss — Heat pump runs longer, uses more electricity
1/8" 25% efficiency loss — COP drops significantly
1/4" 40%+ efficiency loss — System operates far below design
The math is simple: A heat pump rated at COP 3.0 with 25% scale loss effectively becomes COP 2.25. That 86% savings NYCHA celebrated? Scale could reduce it to 68%.
Efficiency Loss Example
Design COP (Coefficient of Performance) | 3.5 |
1/8" scale = 25% loss | -0.875 |
Actual operating COP | 2.625 |
Additional electricity cost | +25% |
That 25% shows up on every electric bill—for the life of the system.
Heat pumps operate at lower temperatures than boilers. Cooler water holds more dissolved minerals, which precipitate out when heated.
Heat pump systems circulate water constantly. More flow = more mineral deposition = faster scale buildup.
Heat pump heat exchangers have narrow passages. Even thin scale layers significantly restrict flow and reduce efficiency.
Without scale prevention, the efficiency you paid for slowly disappears.
Location: Laiyuan, China
Property Type: Lakeside Hotel with heat pump system
The hotel's heat pump system—responsible for both space heating and domestic hot water—was vulnerable to mineral scale. Without protection, efficiency would decline, energy costs would rise, and guest comfort would suffer.
Vulcan mineral descaler installed on the heat pump system. For hotel applications, the Vulcan S25 or S50 provide ideal capacity.
"The heat pump has been running efficiently."
"The pipes are staying clean."
"No new scale has formed on the shower heads or hot water faucets in the guest rooms."
"The eco-friendly Vulcan descaler has completely replaced their water softener."
Why This Matters for NYC Buildings: If a hotel in China can protect its heat pump investment with Vulcan, the same technology can protect the thousands of heat pumps being installed across New York City with Con Ed incentives.

Con Ed's $2.1 billion program pays for installation. It does not pay for long-term performance.
Heat pump equipment purchase
Installation labor
Permitting and engineering
Initial commissioning
Long-term maintenance
Scale prevention
Efficiency preservation
5-year performance guarantees
The result: Building owners receive thousands in incentives for installation, then watch efficiency erode year by year as scale builds up.

System Size | Typical Application | Recommended Model | Pipe Size | Flow Rate |
|---|---|---|---|---|
Small commercial | Restaurant, small office, retail | Up to 3" | 65 GPM | |
Mid-size commercial | Hotel, school, multifamily | Vulcan S25 or S50 | 4-5" | 130-300 GPM |
Large commercial | Hospital, university, district system | Vulcan S100 or S150 | 6-8" | 530-790 GPM |
Heat pumps are the primary path to LL97 compliance for most buildings. But here is what the law actually measures: actual emissions, not design efficiency.
Maintain design COP
Meet emissions projections
Avoid $268/ton fines
Gradual efficiency decline
Higher-than-expected emissions
Unexpected fines
Scale prevention isn't optional—it's essential to meeting the emissions reductions LL97 requires.
About Vulcan Mineral Descaling Technology
All Vulcan units are secured via our specialized anchor mounting system, providing a permanent, vibration-resistant fit for industrial pipes. As a mineral descaler, Vulcan uses custom-tailored impulse bands to treat water flow electronically, preventing calcium and magnesium from forming hard deposits while leaving the water's chemical composition unchanged.
Pipe diameters from ½ inch to 40 inch
Works on every pipe material: iron, inox, copper, stainless steel, galvanized iron, plastic, PVC, PE-x, hose, compound pipes
Fully cast in acrylic for optimal quality endurance
Do-it-Yourself installation without cutting pipes
Zero salt, zero chemicals, zero maintenance
Apply for Con Ed incentives before installing new heat pumps.
Include scale prevention in your project scope from the start.
Document baseline efficiency to measure long-term performance.
Monitor delta-T annually to catch scale buildup early.
Model your LL97 emissions with and without scale prevention.
