There are always questions surrounding new or improved technology and there's always an answer. Some of the most important questions are "why?". Why should you purchase a portable air conditioning unit, when you can have a stationary window mounted unit instead? Portable A.C. units are desirable for many reason, for example what if you live in an apartment and a window mount A.C. unit is not allowed? Do you ask the owner to install several ceiling fans for each room just to keep the area's mildly cool? You could just purchase a portable air conditioning unit and save yourself the hassle. Instead of having every fan on to keep the area cool, the A.C. unit moves with you so you don't have to waste the extra energy on the unoccupied rooms. The A.C. unit cools much faster and sustains the temperature, whereas a ceiling fan can't keep the room cool if warm air keeps siphoning in. Though the A.C. units need to be vented, they're much more efficient than a ceiling fan in keeping the room cool.

Why not pick a portable air cooler, or a swamp cooler instead of a portable air conditioner? An air cooler and swamp cooler both use evaporation to cool the air when most Portable A.C. units use freon or a compressor which helps keep humidity low, making them optimal for an electronics room. Though some people may argue that freon in large amounts is unsafe, most A.C. units use compressors or very small amounts of freon, making them non-threatening for homes or the environment. As the air passes through the compressor area, it's dehydrated and the liquid is collected in a small reservoir. This condensation collected can grow tiny microorganisms such as Legionella pneumophila which can lead to Legionnaires disease. When properly maintained and cleaned the unit poses no threat of creating any such incident. Most Portable air conditioner units have the capacity of 1,800 to 18,000 watts an hour of output, making them fairly energy efficient for what they give in return. All portable A.C. units come with hoses for the venting system, which usually have extensions as well. So if you're using the unit in an office, in your computer room, in your bedroom or on an enclosed porch, the vent can be routed out of range. Because Portable Air Conditioning units don't require any installation and use a simple three pronged outlet plug, they're so efficient and effective for anywhere you want to go.

Renting Portable A.C. units can be much more effecient and much cheaper than purchasing one. Portable air conditioners can range from very large, for a group event, and very small for just one person. The prices will also vary greatly depending on the size, brand and type. Large Portable Air Conditioning units that use Freon tend to be more expensive than ones that use compressors. Many companys will rent the units out from one day to up to two weeks, without renewing the contract, depending on your needs. To get price quoting, the company goes through many specific steps to help you get the right unit for your needs. They'll ask what the event or need is, the amount of space that needs to be cooled, how long the unit is needed and the location the unit is being used in, which is mostly to help them identify whether a more powerful unit will be needed. Many of the smaller rental units are fairly light weight, 80-120 pounds, but most come with free set up/installation so you don't have to worry about straining your back.

So whether you want a Protable Air Conditioner for your home, office, at an indoor event or even an outdoor event, Rental companies will help you get the unit that's perfect for your needs and then set it up for you.

The main advantage of portable air conditioners is their flexibility which allows you to move them from one place to the other hence many people have resorted to using them nowadays. Portable air conditioners also come in handy in places where you are not allowed to use the standard window air conditioners or when you cannot afford the more expensive central unit air conditioners.

Most people looking for portable air conditioners have to choose between a single hose and dual hose portable air conditioner. Both of these air conditioners have the same functioning mechanisms with slight variations. The dual hose can be said to be much better since it has two hoses rather than one. One of the hose takes in the air for cooling from the outside while the hose air comes out through the other hose.

A dual hose portable air conditioner is more efficient since it operates much faster compared to a single hose. Most of them come with two fans which make the cooling process faster. The only drawback is that there is more energy usage with the dual hose system as a result. It can also operate as a single hose if you want by simply removing one of the hoses hence getting a dual hose is more economical than the single hose. With a dual hose, there is a reduced chance of impurities being brought into the room which happens mostly with the single hose systems due to their mode of operation with one hose.

Your dual hose air conditioner needs proper maintenance just like others and you do this by draining the water collected, replacing filters, venting and cleaning the AC exterior among others. Maintenance is meant to keep the system in good condition always especially during the summer when you really need it. This also helps it to last longer.

There are many online companies selling dual hose air conditioners at different prices depending on the specifications. You can compare the prices against the specifications and get to order the most suitable one. They also come in different sizes that can suit different rooms hence you should buy according to your room size.

When buying a dual hose system some of the things to consider are the cooling power, technology used, dehumidifier rates, hose, length, restart function, drainage system, power consumption, window installation accessories, noise, fan speeds, handles and casters among others. These specifications are usually given by the manufacturers. The hose length of the dual hose system is important since you have to ensure that it is long enough to get to the window or ceiling.

The dual hose air conditioner may not be among the highly rated air conditioners but it no doubt performs better than other non standard air conditioners. The main comparison would be the single hose but with the two hoses most of the limitations of the single hose can be overcome. If you are set on a portable air conditioner, then go for the dual hose.

Hot tub covers are a must for hot tubs or spas that are installed outdoors. The cover will protect the tub during summer time so dirt or leaves don’t fall into the water. In winter, when you’re not using your outdoor spa, the cover will keep it protected from rain, snow or dirt. Hot tub covers can also be used indoors, especially if you don’t want to empty the tub every day or if you want to keep the water hot for a longer time. This is the case of some day spa centers, where water needs to be hot when the first clients arrive.

Hot Tub Covers Types

Depending on their features, there are several types of hot tub covers:

• Seasonal hot tub covers: they cover the whole tub, not only the top and they are suitable for outdoor tubs, to keep away the snow from falling and thawing inside the tub.
• Double hinged hot tub covers: they offer the best protection because they are rigid, but they are difficult to maneuver because of their weight. The middle hinge allows to lift only half of the tub cover, so if there’s only one person willing to use the tub, you won’t need to completely remove the cover.
• Rolling covers: these covers are flexible and very easy to put on and remove, because they are simply rolled over the tub top. They can be made of vinyl or thin foam and they don’t take too much storage space when not in use.

High quality hot tub covers have several layers made of different materials, each of them playing a special role. For instance, fiberglass panels would give strength to the cover, the breathable underside layer would allow water to dissipate, while the vapor heat sealed foam insulation would help keeping the water hot. The vinyl coating can have various colors, the most common being brown, burgundy or charcoal. If you choose a top quality hot tub cover, then it’s most probably that one single person won’t be able to handle it. There’s nothing to worry about, though, because you can buy a cover lifter, which is a mechanism that would enable the easy lifting of the spa cover.

How To Measure For Hot Tub Covers

When buying a hot tub cover, you have to take care of how you measure your tub, because you can’t afford to make a mistake here. If the cover is too small you won’t be able to use it, and if it’s too big it won’t fit on the tub top. Large hot tubs or spas can have multiple shapes, so don’t forget to specify which shape is yours when you go to buy a cover for it. You’ll have to make sure the cover will go over the tub lips you can make a lip to lip measurement, but don’t forget to mention that to the shop assistant. Maybe it would be better to go talk to her before purchasing anything, so you can then follow the advice for correct measurement. As a general rule, it’s better to buy the cover a bit bigger rather than buying it smaller. A small cover won’t fit well on the tub and it won’t be able to keep your water hot.

If you have children, you’d better buy a hot tub cover with childproof locks. Most models feature such locks, but don’t forget to make sure they are really hard to unlock by a child. It’s always better to be safe than sorry and you know how curious children can be. You surely don’t want your little one to fall into the hot tub.

In case of hot tub covers that are exposed to direct sunlight, you may want to buy some maintenance and conditioning products, in order to delay discoloration from UV rays which will inevitably occur.

Radiant floor heating systems are among the best energy savers in modern homes. Hot air is lighter than cold air, so it’s always going towards the upper part of the room, therefore, in many cases of typical heating systems, people still end up with cold feet, because the heating source is placed at a higher level. Or, if you don’t end up with cold feet, you are surely paying more for energy bills. With radiant floors, heating becomes more efficient because energy losses are minimized and the heat will be evenly spread across the entire surface. As these system don’t need to move the air for heating, they don’t generate air drafts that can be daunting to sensitive people or to allergy sufferers. Besides, a home with radiant floor heating will look less cluttered, because you’d get rid of all those radiators which are not the best pieces of interior decor, no matter how fancy or expensive they may be. Such heating systems aren’t new: Romans, for example, were using radiant floors to warm their rooms. Actually, they had slaves maintaining fires under the floors, thus preserving their temperature constant inside their rooms.

Types of Radiant Floor Heating Systems

Although they all look alike, there are three types of radiant floors:

• electric
• hydronic
• air-heated

Electric radiant floor heating systems are using a resistance wire that goes in loops under the floor. As electricity passes through the wires, they generate heat. Installation is easier than for other systems, because the system can be bought as a complete unit and not as separate parts which need to be put together. This system is suitable for small surfaces only, because electricity is usually expensive.

Hydronic systems are based on hot water circulating through looping tubes, also placed under the flooring. The water is pumped from a boiler through the polyethylene tubes and usually the temperature can be easily controlled and adjusted for each room separately. While it seems like an ideal solution, radiant heating comes with a drawback: not all flooring types are suitable. For instance, thick carpets may reduce the efficiency of the heating system, thus more energy consumption being needed to maintain the same temperature as in other rooms which have ceramic tiles or hardwood flooring. This is why many people choose to install such systems only in bathrooms or kitchens, where the flooring is not very well insulated.

Air-heated radiant floors aren’t too common, because they are not as effective as the other two types of in-floor heating. This is obvious if we think that air can’t store heat like water does. There were some attempts from various manufacturers to install them in combination with stone plates meant to conserve the heat, but it seems those weren’t too efficient either.

Depending on the mounting method, radiant floor heating systems can be in slab, in screed or under tile.

If building new, in slab and in screed heating are both great. When renovating, installing in screed floor heating is possible only if you apply a new concrete screed. Prices of radiant floor heating installation are about 20% - 30% bigger than conventional heating systems. However, the comfort offered by these systems and their efficiency are determining more and more people who build or renovate houses to choose them.

Those of you who think it would be nice to install radiant floor heating should strongly consider to avoid using it under solid wood floors, because wood might get cracked because of the heat. Laminated flooring is more suitable, because it’s more resistant to high temperature.
