Commercial Water Heater Services

Commercial Water Heaters & Boilers

Elge Plumbing Company installs and integrates commercial-grade water heating and boiler systems as part of new construction, tenant improvements, and renovation projects. With more than a century of plumbing expertise, we provide full-service installation, from sizing and equipment selection to final inspection and system commissioning.

Our teams handle everything from high-efficiency water heaters and condensing boilers to hot water recirculation and hybrid systems. We work closely with restaurants, grocery stores, retail stores, apartment complexes, senior living and other commercial facilities to ensure that hot water delivery meets both usage demands and schedule requirements. These systems are often critical-path components tied to inspections, so we prioritize performance, compliance, and timely delivery at every step.

From single-unit tankless systems to fully redundant boiler arrays, Elge brings the technical know-how and field coordination to deliver systems that work as designed and pass on the first inspection.

Full-Service Water Heater & Boiler Installation

We support commercial and institutional clients with end-to-end water heating system installation. From bid phase to final testing, Elge’s team integrates with your project schedule and coordinates closely with other trades to avoid delays.

• Accurate system sizing based on fixture counts, occupancy, and usage
• Assistance selecting the right technology: tank-style, tankless, or hybrid
• Code-compliant installations with local inspection familiarity
• Hot water recirculation design for large or multi-wing buildings
• Venting and flue piping, including combustion air and clearance requirements
• Expansion tanks, isolation valves, mixing valves, and temperature controls
• Layout planning for equipment rooms and maintenance access
• Controls integration with building automation systems
• inal inspections, startup, and commissioning for immediate use

We work from construction documents or design-assist partnerships to ensure hot water systems are not only built to spec but fully operational and inspection-ready on day one.

Built for Commercial Demands

Commercial and institutional facilities rely on consistent, efficient hot water. In multi-family complexes, surgical centers, or foodservice operations, we install systems matched to peak demand and long-term performance expectations.

• High-volume delivery with storage and recirculation strategies
• Seamless integration with HVAC, controls, and domestic piping systems
• Gas, electric, and hybrid energy sources available
• Tankless and storage-style options for flexible design
• Redundant system planning for critical facilities
• Lead-lag sequencing and control wiring support
• Combustion air, venting, and make-up air coordination
• Support for safety systems and compliance with energy codes

Since these systems are often tied to occupancy permits, health inspections, or regulatory sign-off, our teams ensure every install meets both technical and scheduling expectations.
