Decapitated – Post Organic
dont have to write huh? lyrics: Sodium sunrise burns my eyes Electric charged reanimation I must recombine my (scattered) mind After techno-crucifixion Growling engines Transmitting praise Audio sensors detecting wavs The factory Reanimates me As a post organic form of life Vacuum breath on the surface Of my positron skin Covered by the barbed wire And life-proof membrane I’m the factory’s newest product Son of serialized destruction Perfect body – perfect soul Reborn in a post organic form of life Oxygen – no longer needed Brain – lobotomized Heart – pumping cyanide Arms – mechanized Eyes – throwing x-rays Tissues – mummified Erased – my memory All the rest is vaporized Baptized in a lake of acid tears I am resurrected in a toxic soul Hardware body – software soul In post organic form Appeared I’ve seen the android god preaching Radiating his nuclear love I’ve seen the world around Bewitched in a pill of mescaline.

Advice for DIY plumbers
Cleaning up your tap water
Our country’s water is something we take for granted is pure, safe and reliable. You might be surprised to discover that the water is not as pure as you have thought. But there are solutions to this problem. Technology has developed ways to guarantee that what comes out of the faucet is wholesome. Nowadays water treatment comes in two configurations: “point-of-entry” and “point-of-use”.
Point-of-entry water treatment devices are an excellent choice when your water issues will impact your homes pipes. In regions with very hard water (that is, water that contains a lot of dissolved metals), a water softener is essential to prevent the scale and other mineral build-up from clogging the pipes. Water softeners will be a good choice if you have hard water which contains too much iron, manganese, cadmium, or radium. A reverse osmosis water treatment system can be an excellent choice to handle a broader range of water problems. Lead, mercury, copper, chromium, arsenic, pesticides, and chloride can be eliminated utilizing this process.Point-of-use water purification systems are installed at an individual faucet to purify only the water coming out of that tap. Carbon filters have been utilized for years to remove impurities that impact the flavor and assure that the water is safe for drinking and cooking. They are highly successful in improving the color and taste of your water along with eliminating pesticides and chlorine.
Upgrading your decor with gourmet kitchen and bathroom faucets
More and more people are replacing their drab old plumbing fixtures with attractive, sleek gourmet faucets which add immeasurably to the look of your kitchen or bathroom. There is a nice range of designs and materials from which to select, and faucets these days are made of materials such as nickel, brass, copper, stainless steel, porcelain, and chrome. The material and style you choose depends on the interior decor scheme you have settled on, as some materials like stainless steel or polished chrome are better matched with a modern decor, while bronze or porcelain look better with a more traditional decor. Gourmet faucets are not overly expensive compared with other decor accents, and if you don’t have the tools or aptitude to install them yourself, it only a professional plumber about 15 minutes to complete the job. In regards to decorative impact, the kind of finish the new faucets feature can range from polished, weathered, brushed, natural and even black, depending on the material you like and the look you prefer. The least costly plumbing fixture, polished chrome, is also a more popular material, but it is usually not the best choice in terms of decorative value. Hunting for gourmet faucets on the Internet is a great idea, but you ought to visit a plumbing or home improvement store so you can see and feel how these fixtures look and perform. Gourmet faucets are so advanced that you can buy them with water filters built into the faucet itself, and also buy anti-scalding valves that will not let the water get too hot.
Water heaters for the home
A house is not a home without hot water, and if you are in the market to get one you can find plenty of options from which to select. The traditional hot water heater uses a tank that contains from 20 to 120 gallons of water and is continuously kept hot 24 hours a day. The disadvantages to tank hot water heaters are that they generally cost more than tankless alternatives since you have to keep the water hot constantly, and when the tank runs out you have no hot water until the tank re-fills and re-heats. A tankless hot water heater will preclude these problems by conserving energy, incurring lower heating costs, and maintaining a steady supply of hot water that won’t run out in the middle of a shower. Tank heaters and tankless heaters are both available in electric and gas models, so you will need to figure out which one fits your needs the best. If you already have a gas line connected to your residence, a gas powered model is likely your best option as long as you can make sure the heater is properly vented. The biggest drawback to any electric appliance is the threat of the power going out, otherwise they make a safer option than gas heaters. Make sure you study the owner’s manual thoroughly and follow all maintenance recommendations, and never delay calling an expert in case something is not functioning adequately.
Advice for home heating and cooling
Radiant heating
Radiant heat can be the most efficient, safe, eco-friendly, and comfortable way to maintain the temperature in your home, and systems utilizing infrared energy have become quite popular. Depending on which radiant heat system one prefers, the floors, walls, and ceilings are warmed by hot liquid or electricity, which warms the items that are close by and then heats the air. Systems like these are in direct contrast to the more prevalent forced-air heating systems which consist of hot air being pushed into an area where it heats the ceiling while the floor remains colder. Depending on your needs you will be able to choose between liquid or electric radiant heating technologies. Hot liquid systems push hot oil or water through a series of pipes, whereas electric systems consist of a a series of cables which are heated when energized. Officially known as hydronic heating systems, hot liquid radiant systems involve a network of pipes laid out over cement floor slabs, or can be installed between plywood sheets. A third method, hot air radiant systems, was commonly used originally by the Romans, and is no longer around since the air just can not store large amounts of heat.
Using electric radiant flooring to heat your home
Widely regarded as the most efficient way to heat a home, electric radiant floor heating is a series of electrical wiring under the flooring. You get a far better distribution of heat with this system since the warmed up floor radiates energy directly to objects and people in a room evenly. You might see a reduction in heating expenses by as much as a third thanks to the steady temperatures and improved heat retention. Maintenance costs for this kind of heating are almost nothing and you won’t have to fret about changing filters, cleaning out ducts or replacing worn out valves. Heating systems using forced air frequently produce drafty, dusty environments, especially with floor vents which easily trap dirt and dust. This system is silent because you never have fans that buzz or radiators that rattle as is the case with conventional heating systems. Because radiant heat can change the moisture content of flooring you should stay away from hardwood floors and choose ceramics, porcelain, or stone instead.
Radiant home heating
Of the three possibilities of heat transfer, radiation, conduction, and convection, this article explains radiant heating, where people and objects are warmed by a separate heat source, and not by warm air currents. Essentially, there are three ways to use radiant floor heating, including systems that utilize electricity, those that use hot air, and those that use hot water. The Romans were the first to use hot air as a method of heating a room, but this application is obsolete nowadays since air is an inefficient way to transfer heat. Electric radiant heat is comparable to having an electric blanket installed underneath your floor since it involves a system of thin electric cables put under such flooring as hardwood, stone, tile or laminated materials. Undoubtedly, the most popular form of radiant heat generation is hydronics, which involves pumping hot water from a boiler through tubing loops installed under the floors. Hydronic radiant heat systems can give more options for room-to-room temperature control as long as you install a system that regulates the flow of hot water in the individual tubing loops in each room. Both electric and hydronic radiant heating systems use one of two installation procedures, either “dry” installation,in which the electric cables or water tubing are inserted between plywood sheets under the floor, or “wet” installations which embed the tubing or cables in concrete. Ceramic tiles are the most effective flooring materials to use with radiant floor heat systems, and non-laminated, solid wood flooring covered by carpeting will be the least effective.

Create a cozy patio during the cold months with a portable propane heater
Whether you place them out on the balcony, deck, or patio, portable propane heaters are cost-efficient sources of outdoor warmth, but propane is also a cause for critical safety concerns. The majority of portable propane heaters are designed strictly for outdoor operation, although ventless radiant propane heaters are available for interior applications, but always check the local safety codes and the manufacturers instructions before utilizing them. Because heater models vary widely, never assume that operating instructions for one model can work with other models, and never use non-propane fuel in a propane heater. If you follow the manufacturer instructions carefully you won’t go wrong, but any deviation from those instructions exposes you to significant safety risks. The questions you have to answer will be how much do you have to spend, what is the size of the area you intend to heat with a single heater, and whether or not you have a place for the heater on solid ground where it cannot be tipped over. There are always tipping risks related to portable heaters, which is why you have to prevent large pets and small children from making any direct contact with the heater. Portable heaters allow a lot of convenience and flexibility since they can be moved around at will, but this advantage also presents dangers as they are also readily knocked over. To be on the cautious side always maintain a clear space of at least three feet in front of the heaters, and never allow flammable material to get anywhere near it.
Heat a room with a propane space heater
Whenever you need efficiently heat a medium-sized room you should give some thought to a propane space heater, but be informed of all the safety instructions beforehand. Consult the operating instruction manual of any new propane heater you get, as there may be restrictions placed on them by landlords or other concerned people. Propane heaters are available in two basic types: radiant heaters, which heat the objects in a room prior to heating the air, and circulation heaters, which heat the air beforehand and then blow it into the room. Safety considerations while using propane heaters should lead you to mount the heater on a wall to prevent pets and small children from touching them, and many heaters have automatic shut-off features which activate once the room reaches a preset temperature. The capacity of the heater always needs to match the dimensions of the room, or else the room will overheat when the heater is too big, or have cold spots if the heater is under powered. Indoor heaters should be the only ones for indoors, and outdoor heaters must never be turned on indoors since they emit high levels of carbon monoxide. Bear in mind that safety is the primary concern, not comfort, therefore do not go to sleep with the heater unattended, and definitely do not put flammable liquids anywhere near it. Brand new propane heaters are always the best choice, as that used heater you acquired from your grandpa is undoubtedly in violation of modern safety requirements.
Enjoy your patio in cooler weather by utilizing a propane heater
Propane patio heaters are an excellent way to prolong the warmer season so you can make use of your garden, patio or deck. Those who have not used them before may be questioning if they are safe to use. As with a lot of the conveniences we keep in our lives, they are easy to use and safe as long as you follow some simple instructions. The least hazardous fuel source is most likely a conventional propane cylinder like the one you would use with your gas grill. Always inspect a tank before you connect it to be certain the collar and valve are intact and that there is no other damage. Always make sure that the tank is correctly hooked up as bad connections can cause gas leaks that can be dangerous near an open flame. These heaters are made to be used outdoors and do not provide ventilation of the gases produced by combustion, and so they are unsafe to use indoors.

Having heating or cooling difficulties? Here is some advice
Spray foam insulation kits
Insulating your residence is an valuable procedure in this day and age as a result of the high cost of energy as well as the desire to preserve our resources as much as possible. Saving money and eliminating insects, dirt, and dust is the reason using spray foam insulation is the only way to go, and as an additional bonus with the energy savings, foam will ultimately return the investment. Dirt isn’t simply an annoying mess but also brings in allergens, and along with bugs can enter a building through little cracks around pipes, cables, ceiling supports, base plates, door and window frames. Outside noise is also reduced, although the largest amount of noise comes through the windows and is best stopped by adding double or triple-pane glass, or more effectively, soundproof windows.
Four of the most popular types of insulation are rock wool, cellulose, fiberglass and foam (like polyurethane and polystyrene). Fiberglass has the benefits of being less expensive as well as easier to install, though there are more benefits to employing spray foam insulation instead. One of the biggest benefits of foam insulation is the ability to close up minor openings and cracks which might be undetectable by the naked eye, something that can not be said of both fiberglass and cellulose insulation. This can help stop insects and dust from getting in the house. The total seal created by foam very nearly eliminates most air infiltration into or out of a house.
One more big benefit of foam insulation is its high R-value, which is the measurement utilized to categorize insulation, and the higher the R-value the better the product. The R-value is the rating which indicates how successfully insulation prevents heat transfer between the inside and outside of the home. It helps prevent air flow since residences which are badly insulated tend be drafty and have cold and hot spots. You could get a more consistent temperature in most weather conditions using foam insulation which removes these drafts. Keep in mind that good insulation could also keep your house cooler in the summer time along with warmer in the winter due to less air movement out or in.
To give you an idea of a few common R-values, unpainted cement commonly is about an R-1 whereas the insulation in the attic of a lot of newer residences is often around R-44. Although thicker insulation usually has a higher R-value, this can differ depending on the kind of material used. Materials which include enclosed air pockets frequently exhibit higher R-values. You will appreciate how this happens when looking at the assorted R-values of several insulating materials. Fiberglass has an R-value per inch of 2.2 to 2.7, rock wool is 3.0 to 3.3 per inch, while cellulose is 3.2 to 3.8 per inch. Foam, on the other hand, has R values which range from 4.0 to 8.0. This additional R-value per inch makes it possible for home builders to use two-by-fours for the outer walls instead of the usual 2×6 construction that is considered necessary for different insulation types. Using this smaller framing has the advantage of providing the owner extra living area, as much as 35 square feet within a 1,500 square foot residence. This is comparable to acquiring an extra linen closet! Other benefits of foam insulation include the fact that it is both fire and insect repellent, helps to restrict condensation of moisture, and it won’t shrink or settle.
But the principal benefit is reducing energy costs since as much as 70% of a house’s usage is the fault of air conditioners and heaters, so it is wise to prevent air gaps. Fiberglass insulation, which can be very useful for certain areas, permits openings around vents, pipes, window frames and door jambs. Foam insulation plugs all these gaps and makes for a more effective seal throughout your home than fiberglass will. The final result is foam insulation can help to save you money on your energy expenses while contributing to the worth of your house.
How does foam insulation work? Polyurethane foam, which has been utilized by appliance companies for many years to insulate water heaters, refrigerators and freezers, is the stuff utilized for spray-on insulation. The expanding foam is sprayed on the surface of the attic or within the walls to produce an unbroken solid mass of insulation. This foam is created by means of liquid polyurethane, which is installed employing special pressurized spray nozzles.
However, as with all chemical products, there are drawbacks to utilizing foam. One of the major drawbacks of foam insulation is that it should be installed by a specialized contractor. This is definitely not a job for the average do-it-yourselfer. This insulation works best during the building phase as it will be especially messy to apply. There could also be problems while working with plumbing or electrical contractors who are not comfortable working around the product if it has already been installed.
Fiberglass insulation
The most common type of insulation used in residential applications is fiberglass rolls, which are usually sold in widths perfect for fitting into the spaces between joists and between wall studs. The large, pink rolls of fiberglass insulation are a common sight. Blown in insulation is used for spaces where accessibility is too difficult, such as eaves and irregular crawl spaces. With this kind of insulation, small pieces of fiber are literally blown into the space using specialized machines. To help protect against settling, which might diminish its effectiveness, a lot of these products are coated with a special adhesive that keeps everything in place. Another possible difficulty with blow-in fiberglass is the mess. Whenever you rile up the stuff, it might wind up everywhere, like on the floor and in your lungs and down your shirt. Therefore, if you plan on using your attic as a storage room, it might be advisable to use the pink rolls and then place plywood on top of the joists. This will give you the added benefit of providing even more insulation for the house. You may also cover the blow-in fiberglass, but managing the rolls is really a lot easier, time-saving, and less expensive.
Insulating your home
Radiant barrier technology has matured to the point where you will be able to enjoy an even temperature in your home in summer and winter and save money at the same time. In the summertime, the first thing that heats up is your roof, which then heats the attic. There will be two approaches to dealing with this, normal insulation (those pink rolls) or radiant barrier insulation. A home gets hot in the summertime when it only has fiberglass insulation to absorb the heat in the attic. Having a reflective side, the radiant barrier sends 97% of the heat back to the roof, so you can avoid turning on the air conditioner. When things get cold in the winter the radiant barrier reflects the heat away from the attic so it stays inside the house, saving on energy costs. A supporting material such as kraft paper, plywood, or cardboard is given a thin coating of aluminum, and the result is radiant barrier insulation. In order to get additional strength look for radiant barrier strengthened with fiber, which also makes the stuff simpler to deal with. A form of insulation you want to always avoid employs a bubble material sandwiched between metal plates, however the metal plates will touch once the bubbles deflate.
