Bock - Water Heaters

Bock Water Heaters are engineered to handle a wide range of heating loads while using minimal energy inputs. They are more robustly engineered than those in their class—the walls are thicker and it has a corrosion protection system. Bock products are designed to last a long time while minimizing expenses.”

These water heaters have features in four key areas, including:

  • Greater Energy Savings – modulating pre-mix blue flame burner reduces fuel consumption by 15% to 25% compared to non-modulating condensing or conventional water heaters
  • Reliability and Durability – heat exchanger-to-tank weld joints are overlapped and double-wall reinforced
  • Less Maintenance – automated cathodic corrosion protection system with no sacrificial anode rods
  • Higher ROI – up to 97% thermal efficiency and minimal maintenance

Founded in 1929, Bock Water Heaters is North America’s largest manufacturer of oil-fired water heaters and a leading producer of commercial gas water heaters. Today, Bock Water Heaters manufactures water heaters designed to operate on any fuel (solar, geothermal, natural gas, propane, oil and electricity) and offers a large portfolio of indirect water heaters and storage tanks.
