Bock's patented C-GLASS porcelain enamel is simply the finest tank lining available in the industry. Extra large magnesium anode rods provide additional protection against tank corrosion.

• 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.
  
• Spare the rod . . . spoil the heater. Corrosion-inhibiting magnesium anode rods provide maximum protection for tank interior. Accessible from the top to make inspection and replacement easy.
  
• Patented C-Glass Tank Lining outperforms industry standards by 53%! Tough, lightweight porcelain enamel is bonded to steel at 1600F and is highly resistant to aggressive water.
  
• Two inch thick fiberglass insulation with R-value of 6.66 keeps in heat.
  
• Optional foam insulation provides increased heat retention.
  
• Large handhole cleanouts are standard on all large heaters, simplifying inspection and cleaning of tank interior.
  
• The combustion chamber is surrounded by water on all sides for cool, continuous operation.
  
• Advanced-designed high-speed flame retention burners for gas, oil and dual fuel.
  
• Dual-bulb immersion control ensures constant water temperature without excessive buildup. Immersion-type high-limit control is provided for "over temperature" protection. Combustion safety controls are equipped with a cadmiumsulfide flame detector on oil models; flame rode or ultraviolet detector for gas and dual fuel models.
  
• All models are available in ASME construction and provided with National Board stamping.
