Choosing the Right Heat Pump

Heat Pumps aren’t a new technology, or even one which has recently undergone a scientific breakthrough which has catapulted them into the spot light! In fact, Heat Pumps have been around for many years. What has brought them back into the spot light is the increasing awareness of the way our lives have an impact on the environment and the ways we can change our homes to reduce this impact.

Heat Pumps offer today’s home and business owners a sustainable alternative to gas, oil and electric heating; all of which use non-renewable fossil fuels to generate heat for the home. Instead of this, Heat Pumps use the natural heat which exists within the atmosphere and ground to generate the same heat. As a result we can now heat our home and water supply from a completely self-sufficient and an in-exhaustible supply of fuel!

So, how does a Heat Pump work? Well, the three main types of Heat Pump are: Air Source Heat Pumps Ground Source Heat Pumps Geothermal Heat Pumps

Lets break them down…

The Air Source Heat Pumps

The Air Source Heat Pump is possibly the hardest of the three to figure out. Basically, it steals heat from the air! That’s it! In the opposite way to how a refrigerator steals heat from the interior of the fridge and expels it out of the back; an Air Source Heat Pump steals latent heat from the air outside your home, compresses it and transfers that heat to your water and central heating supply.

One question that I can hear everyone asking is “but what happens when its cold outside” — which is the time when you really need a Heat Pump to work!? Well to explain that we need to think about the way particles behave. At Absolute Zero (-273.15°C or 0 Kelvin) a particle is perfectly still but when we start to increase the temperature the particle starts to vibrate, as we increase the temperature further the particle vibrates more and so on. This vibration is energy and it is this energy which can be used to create heat for your home. In fact, high quality Air Source Heat Pumps can extract perfectly usable heat from temperatures as low as -22°C.

The Ground Source Heat Pump

Boiling away under our feet is a furnace of molten rock so vast it is hard for our minds to comprehend! It is an almost infinite supply of energy and it is what our very existence depends on. Within this molten rock there is a huge amount of un-tapped heat energy and this is projected up through the Earth and into the ground we walk upon.

As the name suggests, a Ground Source Heat Pump uses coiled tubing, laid deep in the ground to extract the natural heat energy from the Earth. This heat is then compressed and transferred into the home as a usable form of heat for your central heating and water supply.

The Geothermal Heat Pump

A Geothermal Heat Pumps works in a similar way to a Ground Source Heat Pump; in that it extracts heat energy from the ground. But instead of burying a closed loop of piping within the ground Geothermal Heat Pumps make use of very deep bore holes which drill straight down into the Earth. Pipe systems can then be buried as near to the hotter depths as possible and in exactly the same way.

In Summary

The three varieties of Heat Pump are right for different situations and scenarios. But one fact rings true for all three… Once you have paid for the Heat Pump you will have an in-exhaustible supply of heat for your home for many, many, many years to come!

How To Earn Some Extra Income

You don’t have to be deeply in debt to want to know how to increase your income. You might want to increase income so that you can take a dream vacation to Fiji, buy a car or redecorate your house.

Maybe the easiest way to increase income is to take a second job. This doesn’t mean you need to find another job where you would work 30 to 40 hours a week. Just working several evenings a week or one evening and Saturday might get you that increase in income you need. I walked into a nearby restaurant recently and discovered that one of the bartenders was my personal banker. He explained that his wife was in school and he was working Friday evenings and Saturdays to make up for the income that was lost because she was unable to work.

Make money at home

Thousands of people today are increasing their incomes by making money at home. Some are doing this through Internet marketing. You could do the same thing by using the free program WordPress to develop a website and do what’s called affiliate marketing–where you promote the products of other companies and receive a commission for doing so. I know of people who have been able to quit their regular jobs and work at home full-time as affiliate marketers. Alternately, you might develop your own information product such as an e-book and sell it online so that you would be able to keep the entire sale, instead of receiving only a portion of it as an affiliate marketer.

Do you do arts or crafts?

If you have a talent for arts or crafts, you might sell them on the website Etsy. Last year alone, people earned more than $9 million selling their homemade crafts or artwork on this website.

Don’t forget eBay

Some of that “trash” sitting in your basement or attic might be someone else’s treasure. Put it up for auction on eBay, you might be surprised what it fetches. When you run out of your own stuff to sell, you can do as many others and start hitting garage and estate sales on weekends. However, before you do this you need to spend some time researching eBay to see what stuff sells for. If you just go out and start buying stuff willy-nilly, you may find that you can’t sell it on eBay and just end up with more stuff sitting in your basement or attic.

Sell stuff on Craigslist

As an alternative to selling stuff on eBay, you may find you can do even better selling locally on Craigslist.com. The advantages of selling on Craigslist.com are that you don’t have to charge for or worry about shipping costs and you don’t have to pay eBay a commission. However, you do need to be careful about who you sell to, as there can be some real jerks out there.

Get out of debt

If you’re a typical family, you’re probably carrying way too much debt. You may not have thought of this but another way to make extra money is to get rid of that debt. Suppose, for example, that you could cut your credit card debt in half. Wouldn’t that make your life a lot easier? There is a company that could probably help you do just that. Go to the site NationalDebtRelief.com and fill out its free debt analysis form to get started. It could be the best thing you do today.

What Is A Computer Monitor?

A computer monitor is the device that is used to display images generated by the computer. There’s only two main types of computer monitors, LCD (Liquid Crystal Display) computer monitors, and CRT (Cathode Ray Tube) monitors. CRT monitors have been around for a very long, long time. The first CRT monitors have were created around the early 80s. They’ve been in main stream use for at least 35 years, and have definitely seen better days, with LCD TVs taking over 50% of the market share for 2008. LCD computer monitors have only really been popular for the last 5-6 years as they’ve become more affordable for the average user. Now it’s not uncommon to find a good 22″ LCD monitor for around $200, and that’s starting to get up into the premium models.

The monitor’s screen size is measured diagonally, CRT monitor’s screen size is usually smaller than the labeled size by 1.5-2 inches, so a 19 inch CRT monitor has the same screen size as a 17 inch LCD computer monitor. In the older days computer monitors aspect ratio were always 4:3, but now that we’ve discovered wide screen technology the aspect ratio has changed to 16:9 or 16:10, because it allows for more screen space sideways to get an improved picture. CRT monitors typically don’t come in wide screen sizes. That is something you need to be careful of when buying a CRT monitor, because it may seem like it’s bigger, but that’s mostly because of the cathode ray tube, circuitry and the enclosure.

CRT Monitors

CRT monitors contain the display device (which is the cathode ray tube), the circuitry to generate the pictures from the computer’s electronic signals, and the enclosure, this may not seem like much, but the bulk of it is the cathode ray tube. And that’s why CRT monitors are becoming so uncommon due to their heavy weight, and bulky size.

CRT monitors generate their screen images by using a cathode (heated filament) inside a vacuum sealed glass tube. The electron gun fires off electrons at the cathode and they come into contact with the phosphor coated screen that glows when it is struck by the electron beam.

LCD Computer Monitors

The LCD computer monitor, when compared to a CRT display is a major improvement in appearance and size. LCD computer monitors screen size is a much more accurate representation of the screen size. LCD computer monitors are only as thick as the circuitry and the LCD screen inside the case. This means the average thickness varies from 1-2 inches, if that, though the bigger you go the thicker the size gets. I have a 32 inch LCD TV whose thickness is about 3 inches. I know, but that extra inch makes a huge difference.

LCD computer monitors are made up of two pieces of polarized glass that hold a liquid crystal material between them. The backlight creates light that passes through the first piece of glass, while this is happening electrical currents force liquid crystal molecules to align; that allows varying levels of light to pass through to the second piece of glass to create the colors and images on the screen.

CRT Monitors vs. LCD Computer Monitors

CRT Monitors

Pros:

High contrast ratio
High response speed
Full range light output level
Displays natively at almost any resolution
Cheap cost due to the rise in popularity of LCD computer monitors

Cons:

Heavy weight
Bulky and Large size
High power consumption

LCD Computer Monitors

Pros:

Decent contrast ratio
Response rates vary, but are very fast on higher end LCDs
Small size
Small weight
Low power consumption

Cons:

Only one native resolution
More expensive than CRT

So Which Should You Buy?

Go with the LCD computer monitor, you will not regret it. CRT monitors are only cheaper than LCD monitors, because LCD computer monitors haven’t been around for 30 years. It’s year 2008, reward yourself by a getting a nice new LCD flat panel monitor. You won’t notice anything missing, and if you already have a CRT monitor, it’s probably old, and it’s probably going to die, the quality probably isn’t all that good, you’ll notice a huge improvement over your old CRT monitor.
