Ground Source Heat Pumps: All You Wanted To Know
Ground Source Heat Pumps (GSHP) are in great demand for domestic and commercial use in the UK and other parts of the world. GSHP are energy efficient central heating systems. They use the heat inside the earth for heating/cooling living spaces. For this reason, Ground Source Heat Pumps are also called earth energy heat pumps, geo-exchange heat pumps, or earth coupled heat pumps.
Ground Source Heat Pumps have three major components: the ground loop, a heat pump, and the heat distribution system. The ground loop of the ground source heat pump consists of a pipe buried in the ground. The pipe is a kind of circuit which is filled with water and antifreeze. It helps the pipe absorb heat from the ground. The ground loop can be either in a borehole or a horizontal trench.
The heat pump comprises of an evaporator, compressor, and condenser. The evaporator takes the heat from the water which is inside the ground loop, the compressor compresses the refrigerant to bring it to the temperature required for the heat distribution, and the condenser gives up heat to water tank which is connected to the distribution system.
The heat distribution system of the ground source heat pump may consist of under floor heating or radiators or water storage tank. The design of the ground source heat pumps is such that they are able to use underground heat efficiently. Also, as ground temperatures are always higher than air temperatures in winter and less in summers, it further adds to the efficiency of the ground source heat pumps.
Although, the initial installation cost of Ground Source Heat Pumps is more than conventional heating systems, they offer low operational cost which makes them cost-effective in the long run. Co-efficient of Performance (the ratio of the amount of heat produced per unit of electricity) of a high quality GSHP is usually 3 to 4 which is much more compared to conventional electrical heating systems.
All in all ground source heat pumps are a great way to save both energy and your money. You can buy GSHP for your home or office from Ecovision Systems.

Buy Ground Source Heat Pump: Save Your Money & Planet
Are you confused to whether you should buy a Ground Source Heat Pump for your home or office or not? Did you know that a ground source heat pump can alleviate your electricity bill quite considerably? Ground source heat pumps are energy efficient heating systems. They have ergonomic design features that help them use the underground heat for heating the outside air and even water.
Although ground source heat pumps need electricity for running their compressors really quite high. Therefore by investing in Ground Source heat pump you can cut down your electricity bills to a very considerable extent.
Another reason why you should buy a Ground Source Heat Pump is that it allows you to add your bit to saving the planet. The Ground source heat pump is an environmentally-friendly energy system. It doesn’t add harmful carbon emissions back into the environment. Also, if you use solar power for running your ground source heat pump you help in energy conservation as well.
However, when buying a Ground Source Heat Pump keep a few important things in mind. You will need to choose a ground loop for your Ground Source Heat Pump, and there are quite a few choices. There is the borehole loop, a straight horizontal and a spiral horizontal loop to choose from. Your choice of ground loop really depends on the space you have available in the borehole or trench, the quality of ground, and of course your budget! A straight trench costs less than borehole trench, but needs more space.
For ground source heat pumps you also need to decide on a heat distribution system. You can of course use radiators or water tanks, but under floor heating is advisable as it works better.
Then you really need to decide whether you are looking for a complete renewable heating system. If so you can use solar power or other renewable forms of energy to power your ground source heat pump, other than using gas or electricity. Whatever you decide it’s good advise to keep a back up heating system.
The cost of installation of a ground source heat pump would also depend on whether it is for a new development or if it is to be incorporated with an existing heating systems. In the latter case the cost would be less. And, if you have proper wall and floor insulation, the heat demand would be less, further lowering the cost of ground heat pumps.
There are various places where you can buy Ground Source heat pumps.

Heat Pump Swimming Pool Heaters ? Quick Buyers Guide
Most likely, you decided to own a swimming pool for a number of reasons, including recreation, fitness and entertainment. Therapeutic reasons may have also played a part in your decision. However, if your pool is not heated you may find that the water is often not warm enough for you to be able to enjoy using your pool comfortably. This will likely be particularly true at the beginning and the end of the normal swimming season. By heating your swimming pool, however, you can significantly extend the swimming season, allowing you and your family to get far more use and enjoyment out of your pool.
One of the best and most efficient ways to heat swimming pools is with heat pump pool heaters. While they require electricity to operate, swimming pool heat pumps are actually a type of solar heater. These heaters work by capturing heat from the air, upgrading it and transferring it to the pool water. More specifically, heat pumps for swimming pools draw air in from the atmosphere with a fan, which then directs the air over an evaporator coil.
This coil contains liquid refrigerant which absorbs the heat from the air and transforms into a gas. The warm gas then moves into a compressor which increases the heat before sending the gas through a condenser. Once inside the condenser, the heat from the hot gas gets transferred to the cool pool water which circulates through the heating unit. As this occurs, the water temperature rises and the heated water passes back into the swimming pool. The hot gas is then transformed back into a liquid and returned to the evaporator coil, completing the cycle and allowing it to start anew.
Since heat pump pool heaters capture heat from the air rather than relying on direct rays from the sun to create heat, they are able to operate and heat pools even when the sun is not shining. In fact, swimming pool heat pumps will operate as long as the outside temperature is above 45°F. This is a great benefit, especially for people who want to be able to swim and enjoy their pool even during cloudy and slightly cooler weather. This characteristic of heat pumps for swimming pools will also allow you to start heating your pool before the warmest days of summer arrive, providing you with more days of swimming fun each year.
At the same time, heat pumps for pools also offer excellent efficiency and long-term affordability. As long as the outdoor air temperature stays above 45°F, heat pump pool heaters can easily maintain a pool temperature between 80 and 90°F and do so far more efficiently than even the most efficient gas pool heaters. Heat pumps for swimming pools will usually have a higher system unit cost than gas heaters, with heat pump units costing in the range of $1600 to $4600 and gas units costing in the range of $875 to $5,500. However, in the long run, heat pump pool heaters often turn out to be a better investment.
There are two main reasons why this is true. To begin with, despite the higher initial cost, swimming pool heat pumps have a far lower annual operating cost than gas heaters. This is because heat pumps use electricity to operate and do so very efficiently. In fact, it’s typical to receive approximately $1 worth of heat for every 20 cents of electric input. As compared to the efficiency and operating costs of gas pool heaters, this is very attractive. Furthermore, heat pumps for pools will generally last much longer than gas heaters. While gas heaters usually last for at least five years, heat pump pool heaters have an average lifespan of at least five to 10 years.
The size of heat pump that you will require will depend on the size of your pool. However, heat pumps for swimming pools will usually have an installation cost of approximately $350 to $950 which is similar to the installation cost for gas heaters. While handy pool owners may be able to install the unit on their own, it’s highly recommended to have all electrical hook-up work performed by a professional in order to ensure safety and proper, efficient operation of the heating unit.
All in all, swimming pool heat pumps provide an excellent option for keeping pool water comfortably warm and extending the swimming season. By operating even during cloudy weather and by offering efficient, affordable operation, heat pump pool heaters provide pool owners with many great benefits. Perhaps best of all, using a heat pump to keep your pool warm will allow you to get more days of enjoyment out of your pool so you can make the very most of your investment.

Those Dreadfully Wrong Myths About Heat Pumps
New technology will always get attacked and criticised by someone or another. Heat pumps and other eco-friendly have often been in the firing line just like other new technologies. In this article we will tackle three of the main myths about heat pumps and heat pump technology. To help you discover more about why these myths are wrong there are some links included right at the end.
If you are not familiar with heat pump systems it is a good idea to just give you a few interesting facts about the technology. Heat pumps are capabable of harvesting hidden energy that exists all around us. This energy can be found in the outside air, beneath the surface of bodies of water, and beneath the earths crust. This energy is then pumped into a home or property and can warm living spaces and hot water. For those people who want to break away from using depleting supplies of natural fossil fuels then heat pumps could be just the answer. The technology has been around for many years and is being used with great success across the world.
Now we know a little more about heat pumps let us address the first myth. Heat pumps only work well in those countries that have much milder and warmer climates all year round. A few decades back heat pump technology did only work well in those countries that experience a warmer climate but times have changed. The technology has gone through major development and heat pumps are different animals these days. This myth should now be archived away as heat pumps are now being reliably used across the globe to provide heat and hot water to homes and properties.
One other major myth about heat pumps is that they are only capable of generating heat for us. Heat pumps are indeed very competent at being able to harvest heat from natural resources and pump this heat into our homes and properties. However, many of these heat pump systems are also capable of extracting heat from a property during the warmer and months and help keep a house cool. There are heat pumps available that can be even more effective in providing coolness to your property. If keeping both warm and cool is something you would require from a heat pump system you need to make sure you choose the correct type of heat pump.
The next popular myth is that heat pumps are very costly. Yes, heat Pumps can be a lot more expensive to install than other traditional heating systems. Please remember that although the technology can be expensive to install, it will mean that you no longer have to pay exorbitant fuel bills every month. In fact fuel bill costs for your property could drop by up to 70%. So yes, people investing in heat pumps will need to initially pay out more for their systems, but over time this investment pays back through lower monthly fuel bills.
So that is just a handful of myths regarding heat pumps laid to rest. If this has interested you and you would like to read some more facts about heat pumps then it may be a good idea to visit EcoVision? EcoVision have been providing environmentally friendly technology solutions to homes and businesses across the UK, including heat pumps. The EcoVision website really is a great information portal concerning all types of green technology, not just heat pumps. The EcoVision website is good in that it also gives some great examples of houses across the UK who have had heat pumps installed. You will easily be able to find EcoVision Systems on the Internet.

An Affordable Heat-pump Water-heater Retrofit
An Affordable Heat-Pump Water-Heater Retrofit
The engineers at AirGenerate (previously Beyond Pollution) appear to have done something remarkable: create an affordable, effective, heat-pump water heater that can be retrofit onto a conventional gas or electric water heater, more than doubling the energy performance compared with a standard electric water heater. The AirTap A7 water heater has a rated output of 7,000 Btu/hour (7.4 MJ/hour), a first-hour rating of 42.5 gallons (160 l), a maximum water temperature of 135°F (57°C), an efficiency of 240% (coefficient of performance of 2.4), and an energy factor of 2.11. (Energy factor is a standardized measure of performance of water heaters; the higher the number, the better.) All this is in a unit that measures only 18″ wide by 14″ deep by 14″ high (460 x 360 x 360 mm), weighs only 48 pounds (22 kg), and sits on top of a standard water heater. The list price is $499. The energy factor and first-hour rating of the AirTap are certified by GAMA (previously the Gas Appliance Manufacturers Association and now a broader association of appliance and equipment manufacturers).
Heat-pump(from: http://www.building-materials-china.com/buy-Heat%255Epump/) water heaters have always been a good idea, but most efforts to design, build, and market them have failed. With today’s high energy prices, however, consumers should be more receptive to heat-pump water heaters, according to Harvey Sachs, Ph.D., the buildings program director at the American Council for an Energy-Efficient Economy. “The economic savings potential is so much greater than before, with the run-up of energy prices,” Sachs told EBN.
AirGenerate initially produced its AirTap A7 water-heater(from: http://www.building-materials-china.com/buy-water%255Eheater/) kit in Houston, Texas. After selling a few hundred units in late 2007, the company began sourcing the product from an offshore supplier. The outsourcing of production will allow the company to significantly ramp up production. The first of the new (offshore-manufactured) AirTap units were received in January 2008, and about 200 had been sold through May 2008. Of 400 units scheduled to arrive in June, almost all were pre-sold by the end of May, according to Sunil Sinha, chief scientist at AirGenerate.

When a situation such as this occurs, it is really a difficult problem to deal with. Especially if it’s a furnace repair in bc that you are about to do to fix your home heating system. That is a task that you definitely need to hand over to an expert who knows how to do the job in no time. Or else, accidents might happen and you wouldn’t want those to occur, right?
In performing heat pump repair you must be very knowledgeable on how it should be treated. To fix an equipment, for example, you must know how it is used and how it works. Same with heat pumps, you must know its use and how it works for your whole household heating system. A tip that you can use when doing repair on your heat pumps is to check your air filter first. Dust and moist waste might have clogged the air pipes and when that happens a simple cleaning tip will do. In instances that you noticed the air pipes can no longer last, better replace them with new ones. Sometimes it is better to spend a little to save in return. Also, you can have the guarantee that it won’t break down again.
Another heat equipment that might break down anytime in the household is a hot water tank bc. Many house owners surely experience situations like this and to handle problems same with a malfunctioning hot water tank, the best way to deal with it is call your resident water system repair personnel. An incident like this is very complicated so better give it up to a professional who can complete the work with just a snap. And afterwards better ask for some guidance when malfunctioning happens again so that you know what to do next time.
But what about if it’s a fireplace repair bc that you need to get fixed as soon as possible. Well, that is quite more difficult this time. A fireplace repair can also be a very dirty task to handle. This kind of household problem also need some proper guidance. Fixing it yourself might somehow be dangerous for you so better get someone who can fix it for you. Some fireplace problems only require proper cleaning. There are times that your chimney and air passages within the household are just clogged with unwanted dirt.

Ground Source Heat Pumps (geothermal) – Heat and Cool Your Home Without Gas or Oil
Ground source heat pumps (GSHPs), often called geothermal heat pumps, tap into the heat naturally generated many meters below the surface of the earth. Just a little ways down, the earth’s temperature is warm and relatively stable, so these systems can bring controllable and effective heating, cooling, and hot water to residential and commercial buildings. Best of all, they allow people to do all this without having to use expensive and carbon-producing fossil fuels such as oil and gas.
There are two types of ground source heat pump systems: those with closed loops and those with open loops. In closed loop systems, liquid (usually with some sort of antifreezing/antiboiling agent mixed in) circulates through pipes buried beneath the earth’s surface. During the winter, when the goal is warming a house, the fluid absorbs heat from the earth and carries back to the building. This very hot liquid can be effectively used to heat a home, and also quite obviously becomes a free-flowing source of useable hot water. During the summer, the system is designed to actually draw heat out of the building, and either use it to heat water for household use or deliver it back into the ground. Open looped systems are similar, except that the water supply within the pipes is continually refreshed.
The bulk of geothermal (GSHP) systems are the pipes that are buried far underground, so what is needed in your home is a unit likely no bigger than your current hot water heater and furnace. If you currently use oil, you may be able to get rid of or at least substantially downsize the size of your oil tank. Many people worry about the longevity and upkeep costs of this type of system because the bulk of the cost goes into burying the pipe underground. Recently however many companies have been offering 40-75 year warranties on the parts of the system that is buried.
If you already have a forced air oil or gas-fed furnace system it may be easy for you to convert to what is called a “dual system”. In this case you would choose which heating and cooling system would be primary at any particular time – most likely the geothermal system – and the other system will only work when needed, such as during an extremely cold spell in the winter.
GSHPs are quiet and safe. There are no exposed parts, fans, storage tanks, etc. that can hurt kids or pets. Nothing is burned so there is no flame. The heating source is the earth so there is nothing to wear out. They are also quiet because the earth is doing the work of the motors in your current furnace.
The initial cost for ground source heat pumps is greater than that of a conventional oil or gas system. However, that initial cost is often made up in three to six years depending on the cost of fuel and the temperature in your area. The greatest benefit of these systems is that you no longer have to use oil or gas at all, so not only are you not subject to the price fluctuations and uncertainty of these fuels, but you also reduce your own “carbon footprint” in the process.
Ground source systems are easy to install, particularly when they are replacing another forced-air system. In this case it is as simple as a retrofit after the pipes are placed. However, they can also be installed to completely replace the system you already have. If you don’t already have central air conditioning, that can be an automatic and immediate benefit of these systems. Contact an experienced installer and he or she can tell you exactly what would be involved in installing a geothermal heat pump in your home.

Air Source Heat Pumps & Domestic Heating
A big favourite with the green crowd are air source heat pumps. The concept behind an air source heat pump is simple to grasp however the technology behind them is devilishly complicated!
Firstly, air source heat pumps can extract heat for domestic purposes from outside air at temperatures which would seem completely devoid of any heat to me and you. But to an air source heat pump, any temperature above absolute zero is a source of un-tapped energy waiting to be harnessed and transferred to your domestic heating system.
You see, heat is energy and what energy results in are vibrations. The more a particle vibrates the more energy it has and therefore the more heat is has. The reason why boiling water is so volatile is because the molecules that make up that water are being heated and are vibrating like crazy. When water boils we can see the result of these vibrations but when that water cools to below boiling we see water that appears to be still. In reality those water particles are still vibration but we don’t have the vision to be able to see that.
In actual fact everything vibrates, from the chair you’re sat on to the food you eat. It is only when a substance’s temperature reaches absolute zero that it stops vibrating. So using this theory it becomes perfectly reasonable to think that heat energy is available from air temperatures below freezing.
Of course, the heat energy available within the air gets less as the air cools so the efficiency of an air source heat pump is reduced but modern air source heat pumps are known to extract usable heat for domestic heating from temperatures as low as -12 degrees. So for the green crowd, air source heat pumps are an excellent addition to any green homes domestic heating system.

The Lowdown on Mini Split Heat Pumps
Mini split heat pumps will make very good retrofit additions to houses with the “non-ducted” heating systems, like radiant panels, hydronic, and space heaters. They can as well be a very good choice for the room additions, where installing or extending ductwork is not possible.
Just like the standard air source heat pumps, the mini splits have two main components: outdoor compressor or condenser, and indoor air handling unit. The conduit that houses the power cable, suction tubing, refrigerant tubing, and condensate drain links outdoor and indoor units.
Today you may have a central air conditioner that does not matter how your house is at present heated, also you do not need to change and tear down the current system. Mini split heat pumps systems are as calm as a breeze, as well as use very less energy than the other systems also they cover your entire house, and have numerous thermostats thus you can control the temperature in the different parts of the house.
The mini split heat pump system is almost invisible. In fact, small holes are situated high on the walls, low to ground, or else anywhere in between. In addition, your installer can give you suggestions about where you can put them to make sure of utmost system efficiency. The rest of this system is installed partially in the crawl space or else basement, and partly outside. There are not any visible features in your house except small holes.
The main benefits of the mini split heat pumps are their size and flexibility for heating and cooling rooms. Many models will have around four-indoor air handling units connected to one outdoor unit. The number will depend on how much cooling or heating is needed for the building or zone. All zones could have their own thermostat. This can save time, energy and money.
Mini-split heat pumps are often simpler to install than some other kinds of space air conditioning systems. For instance, hook up between outdoor and indoor components generally needs only a three-inch hole through wall for the conduit. The majority of the manufacturers of this kind of system will provide a range of lengths of linking conduits. If essential, you can place the outdoor element as far away as fifty feet from the indoor evaporator.
