Cool air feels good, but high utility bills do not. Efficient air conditioners can save you serious money over the life of the system and keep you just as cool.

When you are considering the efficiency of an air conditioner, size is everything. Oversized and undersized can be equally bad. When a unit is oversized, it will cycle over and over. The constant starting and stopping of the unit will pull more energy, and the dehumidifying properties of the cooling coils will not have time to fully operate. This will result in moisture being blown into the duct works and the ambient air with each start up. If the unit is undersized it will not be able to generate enough cooled air to maintain the desired temperature, and will run constantly.

Air conditioners are rated on their efficiency using a measurement known as the Seasonal Energy Efficiency Ratio (SEER). This measurement is the cooling output divided by the energy consumption with climate and certain other variables factored in. The higher the SEER number, the more efficient the unit, is the general rule. Older units might have a SEER as low as 7 or 8. For a long time, The Department of Energy mandated a SEER of 10 as the minimum for all newly installed units. This figure has recently been raised to 13, and is a topic for debate currently. Some units are capable of SEER ratings as high as 17 or 18.

Window units use EER (Energy Efficient Ratio) rather than SEER, but the principle is basically the same. The principle of “bigger is not necessarily better” applies to window units also. Humidity plays such an important role in comfort, and is often more important than just mere temperature. Smaller units tend to remove more moisture because they have longer runs. When a unit first starts it actually blows a bit of moisture out of the unit. Once the cycle is running smoothly, the condensation of moisture on the cooling cools begins. Therefore, a longer running cycle is going to provide a more comfortable environment.

There are other factors that will increase the efficiency of an air conditioner and result in a reduction of operating expense. A programmable thermostat is one such idea. The thermostat can be set to automatically raise the ambient temperature at night during sleep or when the home is vacant during working hours. A ten degree raise in temperature setting during these time periods can result in a ten percent reduction in operating costs.

Properly maintaining your system will also result in increased efficiency. Routine changing of filters is one of the most important maintenance requirements. Efficiency of air conditioning is an issue that goes beyond savings to the owner of the home or building. It is an issue of national concern. The wide spread use of air conditioning has created a large strain on electrical power demand especially during heat waves. Power generation is struggling to keep up with demand and brown-outs have become frequent during periods of high demand. Air conditioning efficiency takes place on an individual level, but the air conditioning industry is working to improve efficiency with improved models and the development of new technology as well.

As any homeowner knows, there are a lot of things in a home that need to be repaired or assembled when you own a home. For new homeowners just transitioning out of apartment living, you may want to pay close attention to the list of power tools below. You can use the power tools below for remodeling work, assembling furniture and other jobs around the house. The list may be short, but these five power tools can help you get a lot accomplished.

Cordless Drill: A cordless drill is especially useful if you have holes to drill for an ongoing or upcoming project. It is great for making pivot holes for the screws, and you will like not needing to change out the screws between using the screwdriver and cordless drill. A cordless drill for home use is typically a three-eighth inch, while anything larger is usually considered commercial size.

Corded Drill: If you have a large number of holes to drill, you will want to use a corded drill since the cordless drill does have enough power to drill through certain material. Obviously, the attached cord takes away from the convenience found on any cordless tool, but extensions can be safely added to help compensate for the disadvantage and inconvenience of a cord.

Cordless Screwdriver: A cordless screwdriver can help you accomplish the small tasks that that need a good amount of power. For example, you can use it to screw furniture together or drill holes for picture frame hanging or hanging on heavy objects on walls. A great feature on most cordless screwdrivers is a reverse switch which allows you to remove the screw if you need to.

Power Circular Saw: Power circular saws cut more efficiently than regular hand saws and are much easier on the hands. If you need to cut large 2×4s or other lumber, such as particle board, this is a good tool to use. Usually, a power circular saw can cut up to three inches in depth without the need to cut twice.

Jig Saw: The jig saw is a good tool for more intricate work such as cutting around cabinet edges, for example. You will be glad you have it when you find you need to make a tough, tight cut.

Owning a home is a great feeling, but can be even more enjoyable when you have the proper tools to fix problems or more easily improve your home. Purchasing these five power tools will help you be prepared. There are, of course, additional tools you will need but you can gradually build up your tool collection.

Being really passionate about power tools, Ray Walberg is editing countless publications on this particular topic. You can see his observations on ryobi cordless tools at http://www.insidewoodworking.com and various other sources for ryobi cordless tools news.

This article looks at the different types of hot tub heaters available on the market and why you might need a hot tub heater in order to help you make an informed decision.

There are different types of hot tub heaters to choose from, whether you want one for your indoor or outdoor hot tub or indeed for your home spa, you will need to decide which is the best type for you, for example if you use your hot tub a lot then a gas hot tub heater would be a wise investment.

With an outdoor hot tub you want to make sure that you have your hot tub at a lovely temperature all year round, there would be nothing worse than tepid water in the middle of winter!

So what are the different types of hot tub heaters?

The three most popular ones are:

> Wood burning hot tub heaters

> Gas or propane hot tub heaters

> Electric hot tub heaters

As each has its plus and minus points you will have to decide which would suit you best and therefore you will find a more detailed explanation below to help you:

Wood Burning Hot Tub Heaters

The big advantage of wood burning hot tub heaters is that you will not need a circulating pump or electricity for your hot tub. This is because the heating of the water creates a natural pumping action. Obviously using a wood burning heater requires a bit of preparation rather than just flicking the switch for the electricity but the water heats quickly and it is far more economical than using electricity or gas. These type of heaters need to be installed on a separate plinth next to your tub.

Gas and Propane Hot Tub Heaters

These type of hot tub heaters are cheaper to run than electric heaters and are your best choice if you do not have electricity available and you want instant heating. They will heat your tub much faster than an electric heater. If you need to heat your hot tub frequently during cold weather this would probably be your hot tub heater of choice.

Electric hot tub heaters

If you buy a hot tub package chances are that it will automatically come with an electric heater. However, as you have already read there are different hot tub heaters available and if you haven’t already purchased your hot tub you may want to shop around. Electric hot tub heaters hook up to your 110/220V domestic supply and are contained within the hot tub itself. So they are convenient and easy to fix if you have any problems, but you may find them expensive to use.

We have looked at three kinds of hot tub heaters and the advantages and disadvantages and you should now know which will be the best for you. Happy hot tubbing!

One of the tings to decide when building or remodeling a kitchen is the type of stove that will be fit in. The countertop stove is a popular choice to give the kitchen an integrated look. Depending on which type of countertop stove you choose, there are different considerations that you need to consider for your kitchen countertop.

Let us start with the countertop gas stove. Being a gas fed stove, you will need to have a connection to you gas line leading all the way up to the countertop. An electrical connection is also needed if your gas countertop uses electrical features such as automatic igniting sparks and digital timers. Be sure that the gas countertop stove has removable tops to make it easier to clean. A lot of heat is generated sideways from the source of the flame while cooking so it is worthwhile to keep this in mind when deciding on the placement of the gas countertop stove. Adequate insulation is advisable to avoid damaging your kitchen countertop.

Next up is the electrical countertop stove. This countertop stove type generates heat by feeding electricity into heating elements. The only thing to get used to with electric stoves is that it takes a while for the heat level to reach the desired level due to the heating up or cooling down of the elements. On the plus side, the electric countertop stove does not lose a lot of heat sideways compared to the gas countertop stove. Installation is straightforward in which you will need to pick a spot on your kitchen countertop and ensure that there is an electrical power source coming through.

Then there is the induction type countertop stove. This countertop stove uses magnetic induction to heat up you pan directly. There is no heating of any elements on the stove itself. Instead, heat for cooking is generated on the surface of the pot or pan. However, the pot or pan used with an induction type countertop stove must be made of metal that sticks to a magnet. If you a magnet sticks to your pan, then it will work with the induction type countertop stove. You will need to get used to the stove a bit as it is very efficient in generating heat since there is in heat loss to the environment. Water boils very quickly and you can burn your steak quite easily if you think that it fries like a gas or electric stove. Installing the induction type countertop stove is similar to installing the electric countertop stove.

Now more than ever because of the different types of cooking methods and the styles of ovens available people are becoming confused over which is the best oven option for them when redesigning or building a new kitchen in their homes. Hopefully the information provided below will help to make the decision on what is the right oven for your kitchen much easier.

Firstly we come to the conventional oven which normally uses either gas or electric (heating element) to provide heat to the oven for cooking food. Unfortunately with this style of oven there seems to be one problem which is that the heat does not always get dissipated evenly throughout the oven and you may find that you can only cook one dish at a time (even if you have the space for more).

Next we come to the convection oven, which uses a fan inside to move the hot air around the oven and this results in a more even heat being dissipated around the whole oven, which means that all the shelves can be used effectively. Another advantage of a convection oven is that they are more energy efficient, not only do they reach the required temperature faster, but they can also be used for cooking at lower temperatures as well. As previously mentioned these styles of ovens have either a fan assisted or fan forced delivery system for dissipating the heat more evenly around the oven. For those ovens that are fan assisted you will find that the heating element/gas flame and fan are separate usually the heating source is at the bottom of the oven and the fan at the back. Whilst if you have a fan forced oven then you will find that both the heating element/gas flame is surrounded by the fan. In some cases you may even find that your oven is a combination oven meaning it is both a conventional and convection oven. Then there are some combination ovens that are both a microwave and convection oven as well and this has a number of advantages over a normal convection oven, not only can food be cooked quicker in it but you will discover that even less energy is used than a normal convection oven.

Another thing that needs to be considered when looking to purchase an oven for your kitchen is the space where it will be located. Some ovens can be installed in a wall, others under a counter and there are those that are part of a traditional stove/oven combination unit. Then other people will look at just how easy the oven will be to clean. A standard oven will have to be cleaned the old fashioned way (using oven cleaner, scrubbing pad and a good deal of elbow grease). However, if you want you could purchase self cleaning ovens which are provided with a super high temperature setting which is used when the oven is empty and the door is locked. This style of oven will burn off any food left in the oven until it turns to ash and all you have to do is wipe it out using a damp sponge or cloth. But if you don’t want to get dirty, and then consider using your vacuum cleaner to get rid of the ash and dust that has been made. Or it may be you decide to purchase a continuous cleaning oven which has a special surface that helps to absorb and spread out any spills that appear during cooking which can be burned off at a lower temperature. These styles of ovens can be cleaned periodically with just either a damp sponge or cloth just like the self cleaning oven. Unfortunately any larger spills that occur in this type of oven will have to be removed using the traditional method of using oven cleaner and elbow grease. It is wise to clean up any spills as soon as possible else if left too long they will become a permanent feature of the oven.

Vacuum cleaners are devices that use an air pump to create a partial vacuum to suck up dirt and dust, normally from carpeted loors. Most homes that have carpet floors have a vacuum for cleaning. The dirt that is pulled up from the carpet is collected by a filtering system or even a cyclone for later disposal.

There are several type of configurations possible for vacuum cleaners.

Upright vacuums have the pump mounted directly above the suction intake, with the bag mounted directly on the handle, which will rise to waist height or so. The upright type designs normally employ mechanical beaters which often rotate brushes, to help disturb dust enough to be vacuumed up. These beaters are normally driven by a belt that is attached to the vacuum motor.

Also known as cylinder vacuums, the canister type designs have the motor and bag in a seperate canister unit that connects to the vacuum head by a flexible hose. Even though upright units have been tested as being more effective, the lighter and more maneuverable heads of the canister models are quite popular. Some models have power heads, which contain the same type of mechanical beaters found it upright units, although they are driven by a seperate electric motor.

Wet vacs/dry vacs, these types a specialized form of the canister vacuum and they can be used to clean up wet or liquid spills as well. They will commonly accomodate both wet and dry soilage, with some being equipped with a switch or exhaust port that reverses the flow of air. This is a very useful function for everything from clearing clogged hoses to blowing dust into a corner for easy collecting.

Back pack vacuums are commonly used for commercial cleaning, as they allow you to move about quickly and efficiently in a large area. They are basically canister vacuum cleaners, except for the fact that straps are used to carry the canister on your back.

Built in or central types of vacuum cleaners will move the suction motor and bag to a central location in the building and provide vacuum inlets at strategic places throughout the entire building. You only need to carry the hose and pickup head from room to room, while the hose is normally 25 foot long and allows a large range of movement without changing vacuum inlets.

The plastic piping will connect vacuum inlets to the central unit. The vacuum can either be unpowered or have beaters that are operated by an electric motor or an air driven motor. The bag in the central vacuum system is normally so big that emptying it or changing needs to be done less as often, sometimes only once a year.
