The use of electric hotbeds does not require electricity, but when calculating the electricity, it should be calculated according to the size and power of the resistor, in which the larger the size and power, the more power consumption and the smaller the power saving. The higher the temperature of the electric kang, the greater the power consumption. According to the above two preconditions, the electricity consumption of electric kang is about 5 degrees to 10 degrees a night, and electric kang is also a common heating method in today's life.

Features and functions

The invention is mainly used for raising seedlings of fruits and vegetables. The invention has the advantages of rapid temperature rise, high ground temperature, uniform temperature, sensitive adjustment, no seasonal restriction, little influence of external temperature on boundary temperature, automatic control and the like. It can shorten the seedling age and easily cultivate healthy seedlings of suitable age.

The electric hotbed consists of heating and temperature control equipment and seedbed, and consists of electric heating wire, temperature controller, relay, switch box and switchboard. Electric heating wire is a kind of conductor with high resistance. When the current passes through the heating wire, the electric energy can be converted into heat to heat the bed soil, and the appropriate temperature can be kept constant through the temperature control equipment.
