  • 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.
  • 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”.
  • Dual 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.
  • Center flue design – reduces tank flex for longer life.
  • Fiberglass insulation – 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.
  • Hand-cast refractory lined combustion chamber – Only one in the industry – better heat retention, warmer starts, better combustion, reduces noxious emissions.
  • Externally mounted burner – provides easy installation and maintenance.
  • 5 year limited warranty – on steel tank (single family residential installations).
  • 3 year limited warranty – on steel tank (commercial installations).
