What heating is healthy? Radiant heat

Especially in the cold season, we yearn for a warm and cozy home. But what is most heating healthiest?
 
We humans spend two thirds of our lives in enclosed spaces, which need to be warmed. Heat sources, there are many. What must, however, especially allergies to look out for? Which source of heat is good for us?

To do this, once we see our history. All life on Earth has in the radiant heat of the sun developed. The heat radiation (infrared) of the sun penetrate virtually without impact the Earth’s atmosphere. Only when striking objects creates heat. This heat is used by these objects is also stored. Without these beams would be no life on Earth. This kind of heat is also called radiant heat.

Radiant heat is healthy

The skin of the human absorbs heat rays. The longwave infrared radiation from the skin surface is absorbed and the shortwave infrared rays penetrate up to 7 cm into the fabric. Around a quarter of the quantity of blood circulating in the skin. This carries the warm blood in the heat all parts of the body. With radiant heat can lack the enzymes to perform tasks adequately. Acute and chronic diseases are then mapped out. In order to eliminate these diseases, there are medical treatments, with radiant heat. Therefore, our heating these have radiant heat.

Heating with radiant heat

Originally, the man with radiant heat from the cold protected. The beginning was an open fire. This resulted in a wide variety of fireplaces. All had a common: They gave their heat as radiant heat Sustainable Furniture.

Even in the Roman Empire people had the beneficial effect of the thermal radiation detected. They moved into the walls of pipes in which hot water circulated or had in the walls of cavities in the hot air was hineingeleitet. It created the Tepidarien. The Tepidarien, however, are not an invention of the Romans. The first Tepidarien well the Chinese have already built much earlier. Later, our ancestors developed ovens. The development ended in the stove. Some old houses in a few heating stove in operation.

What did all these heaters together with the sun? The radiation of the sun and the rays of the heaters do not heat the air but the body and objects to which this radiation hits.

Heating with convection

With the invention of steam engines wanted our ancestors in the near past, the steam for heating use. The wall heating as the ancient Romans had been forgotten. Towards the end of the 19th Century came the Green Insulation on as it still is widespread. First, in cast iron radiators, then much later today standard sheet metal radiator. These heaters have the disadvantage that the air is heated and the walls remain cool. This is also a quick uncomfortable atmosphere.

In the summer disturb us 18 ° Celsius room temperature barely, but in the winter, we feel at 21 ° Celsius fröstelig. This is because in summer the walls are warm, and although the air is relatively cool, do not bother us. In winter, however, the air warmer than the walls.

The Solar Attic Fans lets the warm air rising and cold air sinks back to the ground. This creates a temperature difference between floor and ceiling of housing more than 15 degrees Celsius. These constantly rising and sinking air, of course, also the fine dusts. This is very unfortunate, especially for allergy sufferers. Many suffer in winter under dry cough and other similar malaise, without a cold to be. The cause of the dust, which repeatedly inhaled.

What heating is healthy?

Our heating should warm us, but it should be energy saving and environmentally friendly work. Another very important requirement is: You should create a healthy indoor climate. But what is a healthy indoor climate? Mean temperatures and cool, unmoving, as well as dust-free air. Baubiologen recommend radiant heat as the healthiest type of space heating. Radiant heat as the man feels very pleasant. Heating, with radiant heat work, create a uniform and dust-free air, that is, a comfortable climate.

The usual central heating, warm the air. This creates a convection. Through this, our air interlacing dried mucous. By circulating air, the fine dust swirled, fungal spores and the droppings of house dust mites as well Composters. Even fine dust is the topic of high current, and also awareness of the. The extent of health damage caused by the particulate matter can now only be guessed at. Experts say that during the heating in homes in some fine dust loads are higher than on a busy street intersection.

The healthiest source of heat is radiant heat

It is clear that the radiant heat is the healthiest heat. The sun makes it against us. In radiant heat with heated rooms have harmful bacteria, mold and moisture no chance Water Conservation. The radiant heating produces thermal radiation as the sun. Both operate on the same physical principle of longwave infrared radiation. Of course, we can not immediately Konvektionsheizungen all by radiation heaters replaced. Who is building new or reconstructed, but ruling out a radiant heating schedule. The most advantageous variant of a radiant heating is a hot-wall heating combined with a thermal solar system and large storage tanks. So that little or no nachgeheizt be.

Meanwhile, there are also stone-infrared heaters, which consume as little electricity as a heat pump would also consume. This is ideal for renovation or as a replacement for one heater. Also effective in the acquisition, as this stone heaters only about half the price of a standard hot water heaters. Furthermore, the heating costs about 50 percent lower than a gas or oil heating. In addition, these heaters produce no exhaust fumes. Good for us all.

Heating conversion, replacing the old heating system recommended

In older buildings are at some point the heater or parts thereof should be replaced. Here, the costs should be scrutinized. The replacement of a boiler is often higher in price than the purchase of a complete infrared heating stone.

For renters, however, is not so simple. But there are also some effective solutions. It should anyone have their own health to love, live in apartments with a radiant heating. Due to the constantly rising price of gas and oil will be a radiant heating also cheaper than a traditional Konvektionsheizung.

Solar energy: solar, evacuated tube collectors, collector

Solar Tubes produces energy collectors for heating and showers. The solar panel technology is environmentally friendly and helps to reduce heating costs.

Solar panels on the roof to collect the sunlight so that water and bring to boil. This allows direct heating can be saved. Solar energy is available in abundance and produces no pollutants. Therefore, providing a solar made a valuable contribution to reducing carbon dioxide emissions.

Solar energy, solar thermal: heat and electricity from the sun

More and more households in Germany use the sun as an energy source. Thermal solar systems produce hot water that, for heating assistance and showers can be used. Photovoltaic systems provide contrast with the help of the solar sun.

How does a solar thermal?

The most important element is the solar collector. There are flat-plate and evacuated tube collectors. The collector absorbs the sunlight and converts it into heat. The heat is then thin copper tubes, with a special liquid filled, forwarded. These solar line with the solar memory. The solar storage tank is a way in which the solar heat through a heat exchanger to the water is transferred. A pump keeps the cycle in motion.

Save energy with solar flat plate collectors

A flat collector from the outside looks like a thick, black glass. It is structured as follows: on the roof towards the rear of the collector, an approximately 7 cm thick insulating layer of rock for minimal heat loss. Over the insulating layer are the tubes, which are usually made of copper. They contain the liquid heat carrier. It is entirely the black absorber layer. To protect the collector against wind and weather, the entire element with a highly transparent glass sealed. An exterior aluminum frame ensures stability.

Solar tube collectors

The principle of heat production is at the tube collectors and flat collector equal: The sun heats the Solar Products. This gives the heat from the water. The difference between the two types of collector consists mainly in the insulation. For tube collectors, the insulating layer, a vacuum.

Construction of a collector tube

A Solar Attic Fans consists of many adjacent glass tubes, which are evacuated. That means they contain no air. So much like a modern glass window. In the tubes, the absorber layer. The absorber tubes are directly from the heat transfer fluid flows through. The individual collector elements lead above the collector in a collective leadership, with the memory is connected. The collector is effectively insulated.

Solar energy: the size of the collector surface

For a four-person household needs about five to six square meters of collector area for water heating. Then have a 300-liter water reservoir. If the solar heater to help increase the space on seven to nine square meters, depending on the Collector. Then the tank must also be greater: some 500 liters are needed.

Thermal solar system: targeting the collectors

The orientation of the Solar Lighting system on the roof is not as crucial as, for example, a photovoltaic system. Of course, the south side the best side, but also with east / west roofs can still be 80 percent of the maximum amount of heat generate.

A thermal solar installation

The collectors can be either mounted on the roof than integrate into the roof. On roof installation takes two days to complete. The installation of a Solar Panels system is only for historic homes authorization. For the construction of a solar system, there are government grants. Grant applications are at the Federal Office of Economics and Export Control (BAFA) asked.
