Insulated copper pipes
Copper pipe in insulation for air conditioners allows you to reduce the consumption of the working substance, and hence the electricity. At the same time, copper with thin walls, without proper insulation, significantly loses temperature.
TEN - Tubular Electric Heaters
TEN (tubular electric heaters) for a water heater is used to heat water in a storage tank. It is a hollow tube made of copper.
The ends of this tube are fixed to a flange. The nichrome thread inside serves as a conductor. It is covered with a thermally conductive electrical insulator, which is most often magnesium oxide.
As a result of the passage of an electric current, the filament heats up and transfers the generated heat to the tube, which, in turn, heats the water.
