Whether water is heated by electricity or gas, the temperature of the water is controlled by a thermostat that "senses" temperature. As water heat reaches a preset temperature, the thermostat responds by closing the switch that allows the electric current to flow. When water falls below the pre...
Gas is more efficient for generating electricity and heat. Mass production of technically superior and less expensive batteries will finally send the internal-combustion engines of automobiles to the "dustbin of history." Widespread use of electrical transport will increase energy efficiency, and this ...

Both electric and gas geysers are good if you take the necessary precautions. If you have a very large family of adults, a gas geyser is good. It’s because a gas geyser is fast and can heat a large amount of water within no time. Also, if adults handle it, there’s no chance of...

Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion (转化) of other sources of energy, l___ coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. The energy sou...
This is why you see an “aux heat” light on it. If your heat pump does not have aux heating, it is up to you to determine how to obtain backup heating. Adding auxiliary heat. Using a duel fuel system that includes a heat pump and a gas furnace. Buying one or more space heaters...
D Crass-powered gas is set to heat thousands of homes for the first time in the coming weeks. Energy firm Eeotricity is expected to begin supplying gas to 5. 300 homes frum its plant near Reading through the distribution company Southerm Gas Networks in April. Research has estimated that ...
Because the heat from a glass-ceramic induction hob is transferred directly to the cooking vessel, most of it (85 to 90 percent) stays in the pan. Less heat is emitted into the kitchen compared to traditional gas or electric stovetops, reducing the need to use the exhaust hood and air-...
For example,people have for many years been using the reflected heat of the sun to cook by.Solar cookers have been built with several curved mirrors reflecting the sun and focusing its heat on the cooking element.This apparatus can be used just like a gas or electric stove; it is more ...
