Designing Boiler Systems for Absolute Continuity
For public entities like hospitals that operate around the clock, losing hot water or heating is simply not an option. Our design-build teams prioritize rock-solid boiler infrastructure, engineering and installing high-efficiency systems that never quit.
The Risks of Operating Antiquated Boilers
Aging cast-iron boilers represent a massive failure risk and a continuous drain on maintenance resources. As these outdated systems degrade, they consume massive amounts of energy and frequently trigger expensive emergency service calls during the winter months.
Flawless Execution of Complex Mechanical Replacements
Upgrading a central boiler room requires seamless coordination to keep the facility running during construction. By completely eliminating the handoffs between separate engineering and contracting firms, we ensure a safe, efficient transition to modern heating technology.
Reinvesting Energy Savings Into Facility Health
Modern condensing boilers drastically cut natural gas consumption, immediately freeing up operational dollars. We often help clients leverage these exact savings, alongside SECO grants, to fund the mechanical upgrades without draining their capital reserves.

Frequently Asked Questions
How long does a commercial chiller or RTU replacement project take?
On-site mechanical equipment swap-outs are scheduled during school breaks or low-occupancy windows (1 to 2 weeks). Pre-construction engineering, manufacturing lead times, and structural analysis take 3 to 6 months of advance planning. E3 guarantees zero disruption to active instructional terms.
Can E3 integrate new VRF and RTU equipment into our existing building automation?
Yes. E3 installs open-protocol BACnet IP communication gateways that integrate new HVAC units directly into your central web dashboard, providing unified control over room setpoints, schedules, and alarm notifications.
How does E3 guarantee the energy savings for mechanical upgrades?
E3 conducts an Investment Grade Audit (IGA) to baseline historical utility bills. Post-installation, savings are measured and verified per IPMVP Option C protocols. If verified savings ever fall short, E3 pays the difference.
