The
heating rod is one of the most commonly used equipment for fish
farmers. There must be many problems and precautions in the process of
use. The following explanations are given to everyone.
There
are too many brands of heating rods, and now the quality of domestic
production is also relatively high, such as innovation, silver, and so
on. Imports are like wolfs and interplanets. Heating rods have a useful life, usually no more than two winter months. For a long time, the wires are aged and the contacts are oxidized and may malfunction. Even if imported heating rods, the stated life expectancy in the brochure is within 1-2 years. To be on the safe side, you can use a heating rod in combination with a thermostat. Domestic thermostats have a lot of brands and prices are not high. Set
the temperature of the heating rod slightly higher than the thermostat
by 2°C. This double insurance can avoid the tragedy of burning fish
soup.
Heating
rod power selection problem: Generally calculated according to the
volume of the cylinder, there should be 2W heating power per liter of
water. If there is 300 liters of water in a cylinder, then the total
power of the heating rod is at least 600W. Winter heating may be the most expensive one. I strongly recommend that you keep your cylinder warm. Buy
a few pieces of 2 cm thick foam board, stick the back and side of the
tank, and at the same time make a well-closed lid for the tank, which
can greatly reduce the energy loss. It only takes time and a small amount of money, but it can save a lot of electricity, why not? We must know that every penny we pay is our own labor remuneration. Why can't it make life easier with your own wallet?
Placement
of hot rods: For large fish, the heating rods should be fixed securely,
because some large fish can easily hit the cylinder wall and smash it
by dropping off the tail. Heaters should not be buried in the sand, nor should they be in direct contact with the glass. Once there was an aquarium because the heating rods directly contacted the glass and caused the glass to be heated and broken. Tilting or flattening the heating rods results in better heat dissipation, although this may not look good. Because
the heated water rises, the vertical rods, the hot water produced in
the lower part of the rod and the upper part of the rod have a
relatively small temperature difference, and the heat conduction will be
slower. This undoubtedly reduces the heating efficiency, prolongs the
heating time, and wastes time. energy. For clumsy fish such as Rainbow, it is best to add a sleeve to the heater to prevent fish from getting burned. If there are two heating rods inside the cylinder, try to divide them on both sides of the cylinder and heat evenly. The
thermometer should be placed farthest from the heating rod. This
ensures that the water temperature obtained is not from the hot water
that has just been heated......
