Crest Condensing Boiler
With a BTU range of 750,000 to 6 million, CREST boilers have the power and installation flexibility to provide space heat in any commercial application—all while operating at up to 96.2% thermal efficiency.
The First Name in Efficiency
CREST boilers are equipped with a top-mounted micro-metal fiber burner, engineered specifically for fire-tube technology. The system is designed to ensure smooth, quiet modulating combustion with up to 25:1 turndown. CREST is designed for efficiency to reduce your customer’s fuel bills.
Reduce Installation Cost with Variable Flow Technology
Installation is streamlined, without the time and materials cost of primary-secondary system/boiler piping.High Efficiency with Minimum Supply Pressure
CREST operates reliably with supply gas pressure as low as 4 inches water column. Negative regulation (neg/reg) technology draws gas into a pre-mix combustion system instead of relying on utility pressure through the gas valve. Operation is steady in low gas pressure systems or when peak gas supply demand occurs.Peace of Mind When It Matters Most
Cascade redundancy provides peace of mind because it helps ensure that a CREST boiler system will always deliver reliable performance with no downtime. Cascade sequencing can be programmed for Lead-Lag or Efficiency Optimized operation.
Flexible Venting Options
CREST offers 6 venting options, and it permits direct-vent air intake and exhaust runs up to 100 equivalent feet using PVC, CPVC, polypropylene or stainless steel pipe. Plus, multiple units can be common-vented to reduce time and materials cost.Superior Fire-Tube Heat Exchanger Design
The patented Wave™ configuration creates turbulence as flue gas products flow down the tube, scrubbing the energy from the flue products. The Wave design enhances the life of the heat exchanger by allowing the tubes to flex so they operate stress free with none of the adverse effects suffered by traditional fire-tube boilers.

Control From Anywhere
From wherever you are, the CON·X·US option lets you use any Internet-capable device to link up with any SMART SYSTEM branded control on an unlimited number of applicable units. With CON·X·US, you’re always in touch and in control. Do regular CON·X·US checks for all your customers, and let them know you’re monitoring their unit’s performance.
- Adjust setpoints, domestic hot water, reset curves, pump delays and more, using the CON·X·US interactive display.
- Status alerts via text or e-mail let you know when equipment needs attention.
Smart Touch
This ultimate control gives installers and facility managers access to all of the information they need to set up, troubleshoot and monitor all equipment functions with a multi-color touchscreen interface. Diagnostic information and system status are presented in real words, not codes.
