Boiler Water Treatment Services in New Hampshire
New Hampshire’s cold winters, hard groundwater, and older infrastructure present persistent challenges for boiler systems. Without proper treatment, scale, corrosion, and poor condensate return can reduce system efficiency, drive up fuel costs, and shorten equipment life. EAI Water delivers tailored boiler water treatment solutions across New Hampshire — from Manchester to Concord — to help facilities improve performance, extend system life, and meet ASME and local regulatory standards.
With targeted chemical treatment, responsive service, and compliance-driven support, EAI Water helps New Hampshire facilities run clean, efficient, and dependable boiler systems.

Low Dose Boiler Water Treatment Chemicals
EAI Water offers a full line of custom formulated boiler chemicals designed for low doses, saving costs while minimizing our ecological footprint. Our optimized chemistry formulations hold in sparingly soluble salts well beyond their saturation limits, reducing water use.
Removing boiler water hardness and damaging deposits requires a unique solution for each setting and water source. Our optimized oxygen scavengers provide corrosion control for different temperatures, while our polymer blends provide the right internal chemical inhibitor for scale and corrosion causing minerals.
Boiler Treatment Chemicals Include:
- Phosphates and/or Phosphonates to remove and prevent Scale (scale inhibitors)
- Corrosion Inhibitors to protect internal surfaces
- Polymers to resist particulate accumulation
- Scavengers to remove oxygen (such as sodium sulfite)
- Anti-foam to prevent carry-over
- Dispersants to loosen surface tension and allow active chemistries to circulate
- pH and alkalinity balancers
Steam Boiler Water Treatment Plans with EAI Water Include:
- Producing highest quality feedwater
- Equipment monitoring– Including chemical pumps, drums, controllers, conductivity meters, and filter replacements
- Balancing pH and alkalinity
- Chemicals Added, including oxygen scavenger, antiscalant and defoamer
- Water analysis and report with recommendations
- Remote monitoring and notification alerts
Remote Monitoring for Boiler Water Systems
Production downtime is sometimes unavoidable, but never has to be the result of fouling due to boiler maintenance. Problems resulting from water temperature, pressure, leaks and chemical dosing are not inevitable. A remote monitoring system calibrated by EAI Water will ensure production is never compromised and productivity is always up. We offer training and support so every alert receives the right response.


High Pressure and High Purity Boiler Applications
High purity boiler applications require constant monitoring since they are used to generate reliable power. EAI Water services cogeneration plants which use steam to drive a turbine that generates electricity for large university campuses and medical centers.
