We see objects as black because they do not reflect any of the wavelengths of light that shine on them. A matte surface is matte precisely because it isn't shiny - in other words, because it doesn't reflect the light very well. Matte black is least prone to reflect energy and best at absorbing it. In the case of hot water panels, it is the solar energy that is absorbed that heats the water so the more efficient the panels are at absorbing it, the better it does at heating up the water.

MaxineThe pipes of solar heaters and containers of solar cookers are painted black because black surfaces are good at absorbing solar radiation and converting it into heat. This helps the devices to heat up more efficiently, making them more effective at harnessing solar energy for heating water or cooking food.

Wiring diagram electric baseboard heater?
An electric baseboard heater usually requires a dedicated 240-volt circuit with a double-pole thermostat. The wiring involves connecting the heater to the power supply by matching the colors of the wires (black to black, white to white, and green/bare to ground). It's important to follow the manufacturer's instructions and all applicable electrical codes when installing the heater.
Why do you have black soot with electric baseboard heat?
Black soot with electric baseboard heat could be a sign of dust or debris burning on the heating element. Ensure the baseboard heater is clean and free from any obstructions. If the issue persists, have a professional inspect the heater for any potential malfunctions.
How do you connect a 240 volt electric heater It is a baseboard unit the has a black and red internal wire for connection Do you use 12 2 wire or 12 3 wire The thermostat has 2 red 2 black wire?
For a 240-volt electric heater with black and red internal wires, you will need to use a 12/2 wire for the connection. The black wire should connect to one of the internal wires (e.g., black), the red wire to the other internal wire (e.g., red), and the white wire to the heater's grounding wire or terminal. The thermostat's red and black wires should be connected to their corresponding wires on the heater. Make sure to follow all local electrical codes and consult a professional if needed.
