• Turboflue® - Bock's patented design is the industry's most advanced and efficient heat exchanger. Simply put, it heats water faster and uses less fuel, which reduces energy costs.
• C-Glass®- Durable and exclusive porcelain enamel glass is used to line all tanks and Turboflues. Highly resistant to aggressive water. Fresh silica mixed daily to provide the highest quality.
• Built to last - Hand-crafted from heavy gauge steel. Longer life equals a higher "Return on Investment".
• Multiple magnesium anode rods - Inhibit corrosion and maximize tank life. Electrolysis attacks the anode rods, not the welded seams of the tank.
• Double pressure tested - Only Bock pressure tests its tanks twice.
• Fully welded tank skirt - prevents noxious flue gases from escaping between the tank and jacket.
• Insulation fiberglass (non CFC foam optional) - decreases standby heat loss.
• Accurate temperature control - Only Bock offers dual aquastats or operating and high limits, as standard.
• Spring loaded inspection door - Easy access for inspection and maintenance, also functions as a pressure relief valve.
• Brass drain valve - Accessible, tamper-proof.
• Factory installed T&P valve - CSA listed.
• Multiple large hand holes for easy inspection and maintenance.
• UL listed.
• ASME construction available.
• Integrated 2" steel skid - for safe and easy transfer.
• Wet leg design - surrounds the combustion chamber with water to capture heat from the refractory.
• Fan-assisted burner - facilitates proper system draft, provides clean, controlled combustion and higher efficiencies.
• Externally mounted burner - provides easy installation and maintenance.
• Direct spark ignition - with flame rod controls provides fail safe operation.
• Connects to standard chimney - or a power vented system.
