Upgrading Campus Infrastructure: Commercial Boiler Project in Nashua, NH

Supporting Reliable Hot Water for a University Campus

Reliable domestic hot water is critical for any university campus. From academic buildings and residence halls to athletic facilities and administrative spaces, hot water systems must perform consistently, efficiently, and safely—often under heavy daily demand.

Recently, Denommee Plumbing, HVAC & Electric (DPHE) completed a commercial water heater replacement project for a university in Nashua, New Hampshire, upgrading aging infrastructure with a modern, high-performance solution designed to support long-term campus operations.

This project reflects Denommee’s strength in delivering commercial plumbing and HVAC upgrades that prioritize reliability, efficiency, and clear coordination—qualities that matter most to facility managers and property owners responsible for mission-critical buildings.

Project Overview: Commercial Water Heater Replacement

The existing domestic hot water system included an aging stone-lined tank that had reached the end of its useful life. These older tanks are known for their durability in earlier decades, but they often present challenges today, including reduced efficiency, maintenance concerns, and limited parts availability.

The university needed a replacement solution that would:

• Integrate with the existing boiler system

• Deliver reliable hot water under fluctuating demand

• Reduce long-term maintenance concerns

• Meet current code and safety requirements

Denommee was selected to complete the project based on its proven experience working in occupied, institutional environments and its ability to manage both plumbing and electrical scopes under one coordinated contract.

Expanded Scope of Work

Denommee Plumbing, HVAC & Electric provided all labor, equipment, materials, and coordination necessary to complete the commercial water heater installation safely and efficiently.

Demolition & Removal

• Complete demolition of the existing stone-lined water heater tank

• Proper hauling and disposal of removed materials

• Site preparation for new equipment installation

Careful planning ensured demolition work was completed with minimal disruption to campus operations.

New Water Heater Installation

• Supply and installation of one Turbomax indirect water heater

• Integration with the existing boiler system for efficient heat transfer

• Proper positioning to allow for service access and future maintenance

Turbomax indirect water heaters are well-suited for institutional environments due to their high recovery rates, corrosion resistance, and long service life.

Piping & Mechanical Integration

• Installation of new copper piping from the boiler to the water heater

• Proper sizing and routing of supply and return piping

• Installation of circulator pumps and recirculation components

All piping was installed to align with engineered best practices and current mechanical codes.

Insulation & Energy Efficiency

• Insulation of all new piping with 1” fiberglass insulation

• Reduced standby heat loss

• Improved system efficiency and occupant safety

This step is often overlooked, but it plays a critical role in long-term energy performance and system longevity.

Controls & Electrical Scope

• Installation of a new aquastat for accurate temperature control

• Electrical wiring and final hookup provided by Denommee’s in-house team

• Verification of proper system operation and safety controls

By handling both plumbing and electrical work, Denommee eliminated coordination gaps and ensured a smooth startup process.

Equipment Installed

• 1× Turbomax Indirect Water Heater

• 1× Circulator Pump

• Grundfos (or equivalent) Recirculation Pump

• 1× Aquastat

• Copper pipe and fittings throughout

The water heater includes a standard 10-year warranty, providing additional peace of mind for the facility team.

Why Turbomax Was the Right Choice for a University Setting

University facilities place unique demands on domestic hot water systems. Usage patterns fluctuate daily and seasonally, and downtime is not an option.

Turbomax indirect water heaters offer several advantages:

• High recovery rates ideal for variable demand

• Stainless steel construction for corrosion resistance

• Long service life compared to traditional tanks

• Efficient integration with boiler systems

For facility managers, this means fewer service calls, predictable performance, and improved lifecycle value.

Commercial water heater systems are often overlooked—until they fail. For campuses and large commercial properties, proactive replacement and modernization:

• Reduces emergency repairs

• Improves energy efficiency

• Extends equipment life

• Enhances occupant comfort and safety

By addressing this upgrade before failure, the university minimized risk and gained a system designed for the future.
