Bock Oil Fired Water Heaters

Bock Oil Water Heater

Providing quality in construction, efficiency in performance and durability in operation has earned Bock Oil-Fired Water Heaters a bit of a reputation: they're recognized as the leader in oil-fired water heaters.

  • 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. Read more about Turboflue® at the bottom of this page.
  • 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".

Bock Water Heater's TurboFlue® - Unique Design, Patented Results

TURBOFLUE® is the most advanced heat exchanger throughout the industry. This patented multi-finned heat exchanger minimizes waste heat, transferring it to water for greater efficiency and higher energy savings.

TURBOFLUE® has been in every gas and oil heater Bock Water Heaters has manufactured since it received its second patent in 1960. Bock uses C-GLASS, an exceptionally high-quality porcelain enamel lining that exceeds industry standards by 53% and two (or more) large magnesium anode rods in each heater.

Choosing a Bock water heater is easy. They make custom water heaters to meet your requirements. There are many sizes, features and options to choose from. They may also be installed in a series for high water demands.

TuboflueTURBOFLUE® - Only Bock Water Heaters have it! The Turboflue® transfers more than twice as much heat as a bare tube with baffle. Bock continues to be the leading manufacturer of water heaters because of this incredible invention. The patented Turboflue® fins extend two-thirds up the length of the flue from the lower end - the lower fins are placed in the flue, the better the heater will function. This multi-firmed configuration is tightly welded to perfection. It allows the water to heat much faster using less fuel. Because this is extremely efficient, the heat loss is minimal and the standby losses are reduced significantly: Lower exhaust temperature by 200° - 400° over competitors models of similar input. Bock uses heavy, 12 gauge steel in all waters heaters.

Bock's PowerPlus water heaters are installed with high efficiency burners and foam insulation providing ultimate performance when you need it. These are the highest efficiency ratings in the industry.

Balanced Combustion SystemBurner Field Setup and Adjustment Notice for Bock Water Heaters

Water heaters require field setup and adjustment using proper combustion testing equipment. Although the primary air for combustion is preset for the appropriate firing rate at the factory, this setting is only a starting point and fine-turning is required when the burner is placed into service. The combustion testing of all burners is essential at the time of startup in order to insure the equipment is operating in a safe and efficient manner. It should be noted that combustion testing is required under NFPA Standard 31 for oil-fired burners, and NFPA 54 for gar-fired units. This the responsibility of a licensed installer.

If these units are not properly set up and adjusted on startup, the customer can experience nuisance safety lockout conditions. Other conditions such as improper combustion can result in equipment damage, property damage, excessive levels of combustion by-products (CO- Carbon Monoxide, CO2 - Carbon Dioxide, NOX - Nitrous Oxide) as well as smoke and soot. All of which are both harmful to the occupants and the environment.

Should a customer require technical support or have a warranty issue with the fuel burning equipment, we suggest that they contact the burner manufacturer directly in order to save time in resolving any issues they may have.
