A space heater.
In an electrical space heater, electrical current dissipates energy into heat, and the heat radiates from the element. In a fuel powered space heater, an orifice throttles the fuel feed (resistance to flow), which controls the heating rate. In a steam powered space heater, an orifice throttles the steam (resistance to flow), which controls the heating rate.
since every home appliance has its own rating on which they run.your heater will burn out or become faulty after sometime
It would be P=VI, so 29A*120V=3480Watts
The heater should have a wattage rating (very few list amps). Calculate the amps using the wattage and voltage. Amps = Watts/Volts(480).
It is safe to have a space heater, but it does have risks like anything else. If someone wants to use a space heater, they should be very careful.
Valco Infrared heater can be used as a space heater. The can save you lots of money on energy costs.
An oil filled electric space heater produces a more "even" heating without the hotspots that standard electric space heaters can produce. Also it is not possible for something poked into the oil filled electric space heater to touch the electrical heating element wires as is possible in standard electric space heaters (which would shock you).
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
The local hardware store, or online at various stores. Just google "space heater".
