Electric heating - A kilowatt is the same 3415 BTU

!±8± Electric heating - A kilowatt is the same 3415 BTU

Electric heating can be used as an electrical device that converts electrical energy into heat set. The only thing that drives me crazy is that I see a couple of electric heaters up to 20% more efficient than other electric heating advertised. The bottom line in all this is that the amount of BTU, one kilowatt of energy can be produced by the laws of physics is defined.

Take each kilowatt electric heat and convert it to 3415 Btu per kW is achieved. This fact can notaltered or modified. So to all the demands of their electric heating is more efficient than the next person is totally wrong.

There are several ways to provide heat and can make a difference in the way of feeling the heat of delivery to be done. Can use electric heaters, infrared technology, but they are warmer, without actually heating the air around you. Heaters that keep the oil or to use ceramics to keep the heat can radiate to heat even if the item is notDo you feel welcome, even if the item does not generate more heat. There are several popular ways of heat, but the bottom line is that the BTU is the amount produced by each on a base equal to 3415 BTU per KW.

The exception is the modern heat pump. A heat pump is a device that uses an electrically powered compressor to power a refrigeration cycle that extracts heat from outside air or the soil or groundwater. The heat is then transferredthe room is heated. Heat pumps can be many times more efficient than electric resistance heating.

Another possibility is to save a bit 'of a storage heating system that combines the advantages of cheaper electricity prices. They use electrical building during periods of low demand as the accumulation of heat during the night in a stone or water. This heat is then removed from the stone or water during the day when electricity costs more extracts.

Imagine if you consider electric heater to always remember that with fossil fuelsCentral may be issued only there for 4 units of electricity for every 10 units of fuel energy. Even if you use a 100% efficient electric heating, the amount of fuel needed to make the amount of heat than if the fuel is burned in a furnace or boiler to heat the building. The amount of electricity that is lost through substation transformers and cables is almost 2 / 3 thirds of what was originally produced at the plant.

Electric heating is in goodsome cases, but in many situations, is not a responsible use of our resources. Also, I do not think the accusations that the electrical resistance heater is more efficient than any other. A kilowatt hour of electricity will only convert a 3415 BTU's of heat.

This report was created for global strategic planners who cannot be content with traditional methods of segmenting world markets. With the advent of a “borderless world”, cities become a more important criteria in prioritizing markets, as opposed to regions, continents, or countries. This report covers the top 2000 cities in over 200 countries. It does so by reporting the estimated market size (in terms of latent demand) for each major city of the world. It then ranks these cities and reports them in terms of their size as a percent of the country where they are located, their geographic region (e.g. Africa, Asia, Europe, Middle East, North America, Latin America), and the total world market. In performing various economic analyses for its clients, I have been occasionally asked to investigate the market potential for various products and services across cities. The purpose of the studies is to understand the density of demand within a country and the extent to which a city might be used as a point of distribution within its region. From an economic perspective, however, a city does not represent a population within rigid geographical boundaries. To an economist or strategic planner, a city represents an area of dominant influence over markets in adjacent areas. This influence varies from one industry to another, but also from one period of time to another. In what follows, I summarize the economic potential for the world's major cities for "oil-, solid fuel-, and electric-powered boilers" for the year 2007. The goal of this report is to report my findings on the real economic potential, or what an economist calls the latent demand, represented by a city when defined as an area of dominant influence. The reader needs to realize that latent demand may or may not represent real sales. For many items, latent demand is clearly observable in sales, as in the case for food or housing items. Consider, however, the category "satellite launch vehicles". Clearly, there are no launch pads in most cities of the world. However, the core benefit of the vehicles (e.g. telecommunications, etc.) is "consumed" by residents or industries within the world's cities. Without certain cities, in other words, the market for satellite launch vehicles would be lower for the world in general. One needs to allocate, therefore, a portion of the worldwide economic demand for launch vehicles to both regions and cities. This report takes the broader definition and considers, therefore, a city as a part of the global market.
