Geothermal Energy - Green Heating and Cooling Solution

!: Geothermal Energy - Green Heating and Cooling Solution

You may be seeing more companies advertising Geothermal Heating and Cooling systems and be asking yourself what is Geothermal Energy and why should I be interested in it? A Geothermal heating and cooling system is something that has been below the radar for many years due the impact it could have on the fossil fuel industry; but if you're interested in saving money and doing something good for the environment, a Geothermal Heating and Cooling system is worth doing some research on.

What is Geothermal Energy?

Geothermal Energy is energy stored in the ground that we walk on every day. The ground absorbs the sun's energy everyday and stores it only a few feet below the surface. This energy can be extracted using a series of water pipe lines and then used to heat and cool your home all year round. Geothermal energy on large scale operations is very expensive to tap into through drilling and the ideal geographic areas are limited to supply large cities but systems to heat and cool individual homes have become more practical today than ever before. Due to the limitations Geothermal Energy has for large cities, it's extremely green energy benefits have been over shadowed by the usefulness of Wind Turbines and Solar panels but it's not to say your individual home can't get a lifetime of savings by choosing to install a system like this for your home.

Installing a Geothermal Heating and Cooling System

There are several different ways to install a Geothermal Heating and Cooling system, depending on several different factors. The first thing to consider is the amount of property you own and the second depends on if this system will be a retrofit for your home or something you are considering for a new construction. The most popular system installed in homes today is the Loop System. The Loop system consists of a series of trenches tug in your yard approximately six feet deep and 300 feet long. Obviously for a system like this that consists of anywhere between four to six lengths of pipe stretched 300 feet long requires you to own a piece of back yard free of any septic or well systems. Special underground piping is used to ensure the life of your geothermal system and it is connected to a pump system in your home to convert the water temperature to heat your home in the winter and remove the heat from your home in the summer.

Home Renovation Ideas for Geothermal Energy

If your home doesn't have the property required for a Geothermal Looping System, it doesn't mean you can't get all the benefits from all that geothermal energy can offer your home, it just means you need to consider different ways to tap into this green energy source. One other way is using Vertical loops. This can be done to homes with limited property during the construction of your new home. This method consists of drilling vertical holes in the ground ranging from 180 feet to 540 feet deep. Using the same water pumps that a horizontal looping system uses, you will extract the ground's heat in the winter time to heat your home and transfer your home's heat in the summer months back to the ground through water circulated with heat transfer pumps.

Does your home have an adequate water supply nearby in the form of a farm pond or lake that is at least 8 feet deep? A loop system can be submerged in the lake or pond with a single line trenched back to your home and circulated with water pumps to convert that energy into a green energy heating and cooling system.

Country homes that currently use a well system can take advantage with cost savings through geothermal heating and cooling by using an open loop system. This system requires a second well drilled near your current water supply. Water is drawn from your existing well to circulate through a heat transfer pump that converts the water's temperature into useful energy, then re-circulates the water back into the second well so your original well can draw it again to be continuously reused.

Pros and Cons of Geothermal Heating and Cooling

Pros

- The biggest pro of using Geothermal Energy is that it is renewable and as long as the water keeps circulating, the water will continue to draw and transfer energy.

- Geothermal energy reduces acid rain created by the burning of fossil fuels by 97%

- Geothermal energy will eliminate your heating and cooling expenses to only the expense of running a pump to circulate the water.

Cons

- Due to the expense of trenching water lines approximately six feet deep or drilling 500 feet deep with a vertical system, it could be a very high upfront expense of around ,000.

Geothermal Energy can save your home thousands of dollars in energy expenses and have absolutely no harmful effects on our environment in form of fumes and damage caused by the use of traditional fossil fuels and gases

Green Construction and Heating Systems

!: Green Construction and Heating Systems

Two of the bigger energy uses are cooling and heating. Green heating systems are designed to minimize such energy use during cooler periods.

There are several heating systems used in green homes. One type uses geothermal energy for heat. Geothermal refers to using the natural heat of the earth. Most systems work by running water from under the earth through a series of pipes called a loop. The loop takes the water to a heat exchanger where the heat is removed from the water and used for heating purposes. The most simple is the open loop. Since ground water generally maintains a constant temperature, water is pumped from one well through a heat exchange device, and deposited into a second well, usually at a distance from the first.

A closed loop geothermal system circulates the water through a series of pipes. The pipes are buried in the ground and the water picks up heat and the heat exchanger removes it. There are several arrangements of piping, but the general idea is the same. Although geothermal heat is very inexpensive, a system has to be fairly extensive to provide all of a homes heating requirements, and most systems are intended to supplement other heating sources.

A much better source of heat is sunlight. Solar power systems convert sunlight to heat for use in space heating and domestic water heating. Most solar power systems have a very high initial cost, but a very low operating cost. This low operating cost is often overlooked in the planning stages when more attention is being paid to the initial costs. In order to maximize the advantages of the low operating cost, it is important to make sure that the home is well insulated. In the case of water heating systems, all pipes must be heavily insulated.

Solar water heating systems can be either passive or active. Passive systems use natural convection to move water from the heat source to the heat exchange point. An active system uses pumps and controllers. The water is collected in a tank fitted with solar panels or heat absorbing materials where it is warmed by sunlight. The pumps move it to a heat exchanger where the heat is removed and circulated through the home. In the case of a water heater, the water can be used directly, and it is replaced by cold water from the existing water supply.

Geothermal and Solar heating systems are two examples of green construction types of alternative sources for heat and energy. The advantage is the reducing of the reliance on fossil fuel generated heat or energy. The technology for utilizing these sources of heat is still in its infancy. It is expected that the rise in green construction philosophy will encourage further experimentation in this area.

An Informational Guide To Radiant Hydronic Heating premise And Maintenance

!: An Informational Guide To Radiant Hydronic Heating premise And Maintenance

The radiant hydronic heating law is used in both new and remodeled homes to supply supplementary warmth to rooms and, in some instances, whole homes. This law incorporates a series of tubes into the floor that provides a pathway for heated water to flow through. The heated water generates a warming corollary similar to that of a radiator heater system.

Before beginning the installation it is highly recommended that a certified installer observe the area where the law is to be installed to verify that the sub floor can maintain the new materials which will be added. This inspection helps the establish team to create a practice establish for the area to ensure the tubes will be properly installed for maximum efficiency. It is also recommended that the owner fetch a copy of the installation designs in the event repairs are required.

Two of the more base methods used for installing are slab-on-grade and thin slab. Using the slab-on-grade method, insulation is installed onto the sub floor to supply supplementary energy saving qualities. Next a mesh wiring or mesh lathe is installed over the top of the insulation to supply a skeletal base for the tubing. After using zip ties to attach tubing to the mesh frame, concrete is poured in a depth of four to six inches, constantly securing the warming system.

Another installation type is a thin slab establish that uses two separate methods. The first involves attaching the warming law to the sub floor and then laying a thin layer of concrete over it to supply supplementary security in the middle of the sub floor and the floor covering. The second formula installs the warming in the middle of the sub floor and floor outside creating a sandwich effect. This formula requires supplementary materials for securing the law in place.

Installing the floor outside is the next part of the process; there are two base coverings used for this type of system. Wood flooring is the most sufficient when installing a law of this type as it is easier for the heat to penetrate through the wood than it is to penetrate through the carpet. Carpet, a less expensive option, can be used but requires high conductive aluminum. This type of material provides adequate heat to penetrate through the floor and carpet itself. Using specially designed carpet padding can help to increase the efficiency of the warming from the pipes in the floor.

The maintain law consists of a boiler and pump units. The pump uses the water to keep its bearings and other needful parts lubricated which allows for the device to have an midpoint lifespan of ten years. The boiler unit requires each year maintenance for which programs are generally offered through the installer to program quarterly work to allow the law functioning at a maximum capability. Another thing to watch out for is loss of pressure within the water loop. Most systems are installed with a pressure gauge as this gauge can Monitor the law to see if there are any drops in overall pressure. Loss of pressure can indicate a leak somewhere in the piping; at that point a expert should be notified for repairs.

Geothermal Heating

!: Geothermal Heating

Geothermal heating is a process that has been used since the Roman times. It is a way of heating buildings/spas by utilising sources of hot water that already exist near the earth's surface. In places where Geothermal resources are available it is potential to distribute hot water to multiple buildings. The Geothermal Heating process is seen frequently in countries such as; Reykjavik, Iceland, Idaho and the Usa.

In more new years Geothermal Heating has been done through the use of a Geothermal heat pump. This heating and air conditioning principles uses the earth's ability to store heat in the ground and in water thermal masses. These masses suck up and hold heat. During sunny days when heat is not needed, this thermal mass shop the heat and then releases it when the weather becomes overcast or During night time when the climate has cooled down.

A Geothermal Heat Pump uses land mass as a heat exchanger and operates on the ground. It will stay at the temperature of 50 °F (10 °C) all year round, with a water-source heat pump using the available heat in winter and putting it back into the ground in the summer.

Electricity produced from renewable sources such as solar and wind power can also be used by a Geothermal Heat Pump to heat spaces and water. This renewable vigor can be more sufficient than an galvanic heater at heating spaces and water.

By using this renewable vigor through a Geothermal Heat Pump it heats buildings without the need to converyance and burn biomass on the site. Geothermal Heat Pumps are also uncomplicated and do not wish a high knowledge of technology.

A Geothermal Heat Pump differs from a furnace or boiler as it can replacement heat and not just produce it. Although it does cost more to setup a Geothermal Heat Pump; having one to heat your home and or business is cost sufficient as it will save you on mean in the middle of 35 and 70% on your heating and air conditioning costs. The think behind the height of the premise cost is because the age, the geology of the area, location of your property and quadrilateral footage of living area has to be taken into consideration.

There are three Components that are required for a Geothermal Heat Pump:

o A loop Field - this can be either horizontal or vertical. A loop field is a series of looped tubes that carry heated water from the ground to the heat pump. The distance and capacity of the loop fields vary, the bigger the buildings the bigger the distance and capacity of the geothermal heating component. Also based on the geothermal unit, the liquid in the loops could be in direct experience or indirect experience with the heat source.

o Liquid Pump Pack - This sends water through the loop field and the water source heat pump

o Water Source Heat Pump - This heat pump replaces the furnace or boiler. The heat from the loop field is transferred via this pump to heat the property.

A Geothermal Heat Pump is environmentally friendly, a renewable source of energy, non polluting and becoming one of the most sufficient heating and cooling systems that are available
