Hi Delta®
Sealed Combustion Boilers & Water Heaters

Decades of expertise and technological innovations went into creating the Hi Delta boiler, a product which incorporates features sought after by engineers, installers and end-users alike. The patented burner “security blanket,” an ingenious enhancement that provides a perfected air-gas pathway for complete combustion, makes the Hi Delta the most adaptable sealed-combustion boiler on the market today. Adding to the Hi Delta’s ease of use is the Universal Diagnostic Board (UDB). This key enhancement allows a local technician to quickly review the unit’s entire fault history and make any necessary repairs or adjustments.

Every Hi Delta is factory-fire tested, assuring reliable start-up upon installation. When installed indoors, the Hi Delta’s versatility is revealed in smaller vent diameters, direct-venting and the convenience of stacking without an increased footprint.
