Bock Oil Fired Residential Water Heater Review




Bock Water Heaters Inc. of Madison, Wisconsin is a quiet company that no one ever thinks about, yet they manage to have their oil fired residential water heaters installed in a vast majority of the homes that rely on oil for heat. Their high quality has earned them an almost legendary reputation for durability and operation along with a phenomenal output of seemingly endless hot water. Perhaps the reason they are so quiet is many owners experience a thirty year service life of their oil fired Bock water heaters.

Since Oscar Bock first designed and patented the Turboflue® which is a flue lined with spiraling thin fins that absorb much of the heat out of the flue gases transmitting it to the water in the tank giving Bock oil fired water heaters a high output and efficiency. The Turboflue® design is used on all of their water heaters that use a flame for heating. Bock uses heavy 12 gauge (7/64”) thick steel on all of its water heaters, lining the tanks and Turboflue with C-glass® which is a durable cobalt enriched porcelain enamel glass and is highly resistant to aggressive water. They also come with two magnesium anode rods to protect the tank from corrosion. Bock oil fired water heaters also have a fully welded tank skirt and a hand cast refractory lined combustion chamber for less fumes and better starts.


Bock oil fired residential water heaters come in sizes from 20 gallon up to 113 gallons, and have firing rates of 60,000 to 155,000 BTU. The 32E model water heater is an industry leader delivering 180 gallons of hot water in the first hour with an efficiency rating of .66 compared to an industry average of .58 efficiency. Oil fired water heaters 40 gallon and above are rated as commercial and use thermal efficiency as a measure, Bock oil fired water heaters measure 80% or, higher depending on the model. Bock oil fired residential water heaters come with a 5 year warrantee when used in residential service and a 3 year warrantee in commercial use. When you buy a Bock water heater you are not locked into buying it with a Bock burner you may also buy the water heater without a burner and use one that is on Bocks approved burner list made by Wayne, Carlin, Beckett, or Riello.

Your investment in a Bock Oil Fired Water Heater is a sizeable investment and it is very important that you have it serviced once a year by a qualified technician who will clean the burner and flue, service and adjust the burner, flush the sediment from the tank, and check the anodes replacing them if needed. Treated properly a Bock Oil Fired Water Heater should give you a very long service life.

If you by a Bock Residential Oil Fired Water Heater you will be joining the many quiet users who other than a yearly servicing by their oil company forget that they have a Bock in their home and just enjoy the benefits of one of the longest lasting water heaters on the market today and its seemingly endless supply of hot water.
