Comparing pressurized and non pressurized flow centers

geothermal_home_installationOne of the most difficult things to do is choose the right method with which to heat water in your home. This is because there are a variety of techniques to choose from which could even confuse you. From the outset, you could use heaters that use electricity to warm water. They are available in large numbers. There are other people who use propane to heat their water. That could also be an option. Apart from that, there are methods that use solar energy to heat water. Now that one sounds more effective. However, one option that is effective and is being used by many people is geothermal power. With geothermal power, there are two kinds, those that are pressurized and the non pressurized flow centers.

Even from the term geothermal, you can already guess how this system functions. Naturally, it uses heat emanating from the earth to heat water. Actually, the process is unique, simple and complex at the same time. It is simple in the sense that it employs natural resources to heat up water. One may not need to spend so much in terms of paying electricity bills or buying propane to heat water. The process begins when water flows into the earth. In other cases, it is pumped into the earth from where magma which is always molten rocks below the earth will heat up the water. The water is then transferred into your home for your personal use. You can get this water under pressure or non-pressurized. Whether you want the pressurized or the non-pressurized system installed, it is still possible. It all depends on your needs. However, it is important you understand both of them before you choose on one. One thing remains constant for these two systems. They are very efficient in use of energy.

If you decide to install the non-pressurized loop, there are several advantages attached to it. Firstly, it is less costly to fix it in comparison to the pressurized system. Furthermore, you may have all the loops installed inside your mechanical room! This may not ring a bell to you but it is very helpful. You will suffer less from blockages that come as a result of valves shutting down. The loops in this system are normally open. Again this is an advantage to you as the homeowner as you can add extra fluid without calling for experts to help you. Its design is also much simpler making it easy to modify.

Having looked at the several advantages associated with the non-pressurized system, it is now time to look the other way. Let us focus on some of the reasons you may now want to install the system in the first place. The method is prone to leaks. The first reason as to why the leaks could take place is when the pipes are made out of PVC. They are so easy to leak out which could mean constant repairs and high maintenance costs. This system may also call for constant checking of the fluid levels. This requirement is another reason that causes leaks to occur.

We all know about the hazardous chemicals. For instance, methanol and antifreeze feature among the list of dangerous chemicals. Unfortunately, they are very essential in the running of this system. This means that in case of any negligence, so much damage could occur. The system is naturally slow for the reason that there is no pressure pushing the liquids. As much as it is cost saving, it has its own disadvantages. For instance, the slow movement of fluids allows for bacteria to grow. This means that you will have to constantly clean the system. As if that is not enough, the low pressure system cannot take water in high buildings. This implies that the system is limited to some extent. Only those who live in short buildings can use it. Another disadvantage with the system is that it is not aesthetic. The picture of exposed pipes is not very appealing.

Those who advocate for the pressurized system refer to it as being more organized and being neat. The first thing about this method is that it employs a two connection system instead of three. One could think the more the connections the better the method. But that is not the case here. With two connections, there are less chances of complications coming up. In case the system gets dirty, it is very easy to clean. It has a pressurized flush system that automatically gets rid of the dirt. This means that the method is time saving since it does not require too much manual work. By reducing the amount of manual work on the system, it is less likely to have it getting destroyed. The more people handle any system, the more it gets prone to spoiling. Again, one is less exposed to methanol or antifreeze which are dangerous to humans.

However, just like any other system, it also has its own flaws. Maybe it is the reason why some people prefer its sister system. The first disadvantage with this system is that it is very costly to install. Apart from the installation costs, this system is more likely to become faulty. This time it is not due to human faulting but due to the heating. Heating results into natural expansion while cooling causes contraction. Therefore, continuous heating and cooling can cause it to falter. However, the technicality to solving that issue is re-pressurizing the entire system. Again, it is not easy to detect where a problem has occurred until an interior manifold is used.

When you are choosing the geothermal flow center to heat up water in your home, you will have two options. You may choose the non-pressurized systems since they are less costly and easier to maintain but prone to leaks and growth of bacteria on the other hand. Choosing the pressurized systems would mean you are choosing a more expensive system. However, they are organized and are not prone to complications.

Flow Centers For Your Geothermal Heating & Cooling System

single unit flow centersHome heating and cooling have been found to constitute a significant percentage of the energy costs you incur in any given period. It is for this reason that you should consider the installation of geothermal heating and cooling to reduce heating and cooling costs, in addition to, numerous other advantages.

Geothermal home heating and cooling is the use of the thermal energy that is tapped by burying fluid filled pipes into the ground where the heated liquid is brought up to your home by flow centers or pumps that have been mounted close to furnaces that you have mounted in your home. This liquid is transferred to the home’s heat exchanger which is located inside the refrigeration system of the geothermal system to warm the air inside your home. The geothermal system then distributes the heated air to other sections of your home.

The following is a look at its advantages and the factors you should consider before installation in order to maximize on its benefits.

One of the greatest advantages of installing a geothermal home heating and cooling system is its energy efficiency. It has been found to offer between 70 to 80 percent reduction in energy costs when compared to your conventional heating and cooling system. Its installation can offer you instantaneous savings in cost because it can be included in your mortgage. You may also benefit from reduced rates from your utility company after the installation of a geothermal heating and cooling system.

The Contractors involved in the installation of geothermal heating and cooling systems offer warranties of up to 25 to 50 years due to the durability of the systems. There are measures taken to protect its components from damage brought by contact with the earth, and due to the fact that the components are placed underground, you do not have to worry about vandalism of your investment. There is no comparable home heating and cooling system that can give you such a high return on investment.

Geothermal heating and cooling systems are virtually noiseless unlike your conventional systems that necessitate the installation of condenser units outside your home to reduce noise levels. It is no surprise that you may mistakenly contact a technician to check out the system thinking that it is faulty because it’s zero noise emissions.

Unlike conventional heating and cooling systems that require constant maintenance, geothermal heating and cooling systems require minimal maintenance especially where they have been properly installed. Their reduced maintenance costs and tasks also result from the fact that the mechanical components are installed in your home where they are highly accessible by technicians. The only maintenance task you will be involved in as a homeowner is changing the filter in its heat pump.

It has been found that most of the sun’s energy is absorbed by the earth which accounts for more that we use in any known way. This results to the use of geothermal heating and cooling all year round because of the renewable nature of its energy source. This is regardless of whether its winter or summer.

Geothermal systems can also be fitted with innovative features that provide cooling and humidity control in your home to ensure maximum comfort in their use.

You will be an active contributor to environmental conservation efforts when you install a geothermal heating and cooling system. This is because it does not require fossil fuels or greenhouse emissions. There is a resultant increase in your indoor air quality because there are no poisonous gases such as carbon dioxide and carbon monoxide produced by the system.

A geothermal home heating and cooling system is very effective and this results to even heating of every room in your home. This is in contrast to conventional heating and cooling systems that create hot and cold spots in your home.

The installation of a geothermal heating and cooling system will get you a tax credit offered by the federal government on homeowners who opt to use renewable energy in their homes. This tax credit constitutes 30 percent of all costs incurred in the installation of the system.

Before the installation of a geothermal heating and cooling system, the following factors should be considered.

You should consider using flow centers instead of geothermal heat pumps. This is because flow centers offer considerable savings in heating and cooling costs, require less maintenance, are environmentally friendly and very durable.

A geologist should be hired to study the origin, structure, history and composition of the soil around your property. This is to determine if the installation will be efficient in transferring heat to your home because if it is found that the soils are desirable, you may benefit from massive savings during installation due to the reduced number of pipes required. The geological examination will also determine whether the piping network will be installed vertically or horizontally due to the presence of hard rocks that may present difficulties when digging in either direction.

The installation of a geothermal heating and cooling system is dependent on the size of your land. This is because it determines whether the piping will be done horizontally or vertically. Accessibility to the excavation site also determines whether the contractor will use the horizontal-loop or the vertical-loop system. It is important to note that the horizontal-loop system is cheaper, faster and simpler because it does not require the use of highly specialized equipment when compared to the vertical-loop system.

You may also want to preserve some aspects of your landscape during the installation. The existing structures above the ground may need to be removed before activities such as trenching and drilling can take place. These include telephone and electrical lines, trees and buildings.

Hydrology is the presence of water on your property and its depth. It is also an important factor that needs to be considered before the installation because it determines the type of loop to be used in the installation between the open-loop and the closed-loop.

You should also ask the contractor involved in the installation if the existing electrical installation in your home is capable of powering the geothermal installation or if an upgrade is necessary.

A geothermal flow center for your home – geothermal heating systems

geothermal_flow_centerGeothermal heating system is a modern money-saving way to regulate home temperature. The best part about installing such a system in your house is its Eco-friendliness. Can there be anything better than combing Eco-friendliness along with in-expensiveness. Some people say that the initial cost for setting up such a system is very high. Although this is true up to some extent, there is a lot more to know in this context. The houses installing this system avail a great deal of tax credits from the governments for saving energy and participating in the Eco-friendly drive. Moreover the cost of heating is considerably lower than the other ways. This makes the initial investment worth it. Stay assured a geothermal heating system will save you a considerable sum of money. A geothermal flow center is a very important component of the whole system.

Some basic knowledge about the geothermal heating system -

These work by harnessing the earth’s heat. It keeps the house comfortable and warm without causing any kind of harm to the environment as the traditional methods did. During the warmer days of the year, the earth accumulates heat through absorption that remains there even during the colder periods. The heat absorbed by the earth is more than 500 times than that we can use.Not just the absorbed heat but the earth itself also generates a considerable amount of heat through decay of minerals, etc.

The working of the system is quite comparable to that of underground caves. It keeps the place cool during warm weather conditions and vice versa. A geothermal heating system uses a device known as the ground source heat pump that brings this heat to the house. It works at an efficiency of around 400% in the whole process which makes it quite effective. The whole installation process involves the digging of about two meters’ deep trenches around the house in which pipes are laid. The main purpose of these pipes is to let the water and antifreeze flow through them so as to absorb the heat of the ground. As soon as this water reaches the heat pump, the heat content in it is compressed which magnifies the heat produced. This heat is then circulated in the house. Usually and preferably an underground heating system is used.

Components –

There are 3 important components of this system. First – the loops of dense polyethylene pumps (pipes) that are buried underground. Second – an indoor heat compressor (motor pump) and heat exchanger that transfers the heat from the house to the ground and vice versa. Third – is a geothermal flow center that connects both of these. It is indeed one of the most important components of the whole system.There is a good heat distribution system which helps in even distribution of heat. These also act as heat absorbers during summer to transfer the heat to the ground and make the place cooler. Also, you can have some add-ons to the system to make it even more effective and efficient. These may include multiple speed compressors, variable speed blowers and so on. These two add-ons help in adjusting the time taken for house to heat or cool. Thus they function like regulators. Also, there can also be de-super-heaters installed in the system. These devices take advantage of the excess heat that is generated to heat up water in the house. This can prove to be very handy during the cold season as it helps in saving lots of fuel which is otherwise used up to heat water.

Benefits -

Taking into consideration the tax benefits that the government gives and all the fuel savings, it is a very good alternative for keeping the temperature of a house regulated. Also, it helps in preserving the vulnerable fossil fuels which are otherwise used for generating heat. The scarce electricity is also saved. Moreover, all these fuels are quite expensive. The geothermal heating is very cheap in comparison. It can save at least 75% of your energy bills that is consumed for the purpose of regulating the temperature of the house. This is indeed a great way to reduce the emission of carbon di oxide as fossil fuels are not burnt. So this is dual-benefiting cost wise and responsibility wise. It surely gives us an opportunity to contribute our part towards the environment.

One key benefit of this system is that it can be reversed and can be used to cool the home during the warmer months. Can there be anything better than this? This reduces the need for air conditioners considerably. Hence, works doubly throughout the year to save money and energy. The whole system is really very easy to maintain. It requires no annual servicing or checks. The size of the pump is very small. You can compare it with the size of a small refrigerator. Therefore not much space of your house is consumed by this system.The on-site emissions are the lowest in this case as compared to any other heating system.

Some other important facts -

There are some people who would ask – what about the energy that is required to run the motor? For them it’s worth knowing that the consumption is much lower than that which would have been used to heat up the entire house. Moreover, solar energy can be used by the installation of solar panels in the home to provide the required energy to the pump. The whole system will be much more cost-effective.

There are also questions regarding the initial investment. Yes, the initial outlay is reasonably large. However, looking at the savings that you are going to make through the installation, stay assured that this will be covered in a matter of five to seven years’ time. After this, all that you receive is just savings in your pocket. Additionally, you also get tax benefits from the government if you comply with all the regulations attached.


This system is a very effective one in keeping the temperature of a house regulated. It helps in saving a considerable sum of money on energy bills. Moreover, by the use of this system you can make your contribution towards a healthier environment. Also, there are not many worries with regard to its maintenance.

Choosing The Right Geothermal Flow Center

There are a variety of different ways to heat water for one’s home. One could do it via electricity, solar powered water heaters, or propane versions. One other kind of option is a geothermal flow center. Two different types exist, one relying on water pressure to operate and those that rely on natural forces.

Drawing up heat from the earth, this device then utilizes this energy to warm up water for the home. The magma below heats the above ground, and any pipes that have water flowing through them in the earth will become heated up. After this is done, the water is brought into the home, either being pumped or by using natural forces. This tends to be very energy efficient, and two different systems exist. Each has positive and negative factors.

Non-pressurized loops gain several benefits. One is that the cost of installation is small in comparison to pressurized ones. It can easily be installed inside a mechanical room, and shut off valves help to prevent any blockages from occurring. If fluid needs to be added, the system is fairly easy to access and modify.

Many negative factors come with this type of design. Leaks can occur if the pipes are PVC, or if a person constantly removes the lid to check the amount of fluid inside. Dangerous materials such as methanol and antifreeze are needed for this system, and bacteria can easily grow in the relatively slow moving water. It does not appeal to the eyes well, and it has limitations as to the height the water can be processed.

Pressurized loop systems tend to be a better organized design. Two flow connections exist as opposed to three. This can reduce the possibility of complications occurring. Removing dirt is much easier, as it comes with a flushing device, and thus damage is greatly reduced as well. Owners are also protected from dangerous chemicals, as methanol or antifreeze are not needed.

One disadvantage of this sort of system is that the cost is much more expensive. When temperature changes occur, the pipes tend to become warped, which can lead to the system obtaining some damages and possibly stop working. This can be solved by re-pressurizing the pipes. However, if something occurs, finding it becomes more difficult since there is no interior manifold.

A decision can be made between two different kinds of geothermal flow centers. Pressurized types are more organized and tend to have less complications, but are much more expensive. Non-pressurized kinds tend to be cheaper, but are more fragile and can leak more easily. Depending on one’s needs, considering these factors can help one make the right purchase for heating up their home’s water.

Available Geothermal Flow Center Options

Choosing a method to heat water in the home means looking at a variety of options. Electrically powered heaters exist, as well as propane and even solar powered. One option is a geothermal flow center. There are two different kinds, those that use high water pressure and those that do not.

A geothermal flow center is designed to use heat from the earth to heat up water. The water either flows or is pumped into the earth, and the natural heat sources from the magma below warm up the liquid. It is then processed into the home for use with or without pressure. This is a very energy efficient process, which can be installed in two different ways. The two different systems have their own advantages and disadvantages.

Having a non-pressurized loop has several advantages. It is cheaper to install, and all the loops can be installed inside the mechanical room. This prevents loop blockages due to shut off valves. Since the loops are open, the homeowner can add additional fluid by themselves without professional help, and the simpler design allows for modifications as needed.

Several disadvantages exist. If the pipes are made with PVC or if someone constantly checks the fluid levels, leaks could occur. Methanol and antifreeze are necessary for this system, which would be dangerous. Bacteria grows easier in the slower moving water, and it cannot go high into buildings. It is also not very aesthetically pleasing due to the pipes being generally exposed.

A pressurized loop system is a more organized and neater system. There are only two flow connections rather than three, which means less chance of complications. It is easier to remove dirt due to the pressurized flush system, and the chances of damage to the device is reduced. There is no unnecessary exposure to methanol or antifreeze, which protects the owners.

However, there are disadvantages to this type of system. It is more expensive to install. This type is also more likely to falter out due to temperature changes and the natural expansion and contraction of the pipes. This problem is normally solved by simply re-pressurizing the system. If a problem pops up, it is harder to discover it without an interior manifold.

When choosing a geothermal flow center, one has two options. Non-pressurized systems are cheaper and easier to maintain, but are more prone to leaks and bacterial growth. Pressurized systems are more expensive, but is better organized and less likely to have complications. By determining which one best suits one’s situation, one can make the right choice for their water heating systems.

How To Pick A Geothermal Flow Center

Heating the water for one’s home can be done in a variety of ways. Electrical heating systems, solar panel powered devices, and propane gas tanks are all different ways to do it. A different option is using a geothermal flow center, of which there are two different kinds. There are ones with water pressure and those without it.

Heat from beneath the earth is the source of energy from this water heating system. Magma below ground emits heat, which is transferred into water pipes beneath the ground, warming it up. Once this is done, the water is somehow moved into the home for use, whether via gravity or a mechanical pump. This energy efficient method comes in two different forms, each with their advantages and disadvantages.

The systems which are non-pressurized have various advantages. It is relatively cheap to buy and install, and can be put into an easy to access mechanical room. Shut off valves aid in controlling potential blockages, and if fluid or changes need to be added, it is very easy to modify.

However, there are also disadvantages to this type of device. If the pipes are made of PVC or if the owner continually opens the fluid valve to check the water levels, leaks may develop. Also, the way the system works means that antifreeze and methanol are needed to protect the water, but these substances are dangerous. It is also not very pleasing to the eyes, bacteria can grow in it more easily, and water can only be brought up to a certain height.

Systems that are pressurized are usually more organized and neater than non-pressurized versions. Two different flow connections are used rather than three, which can lower the chances of problems occurring. A flushing device prevents damage from happening due to dirt build up, and since antifreeze and other chemicals are not needed, rick. Poisoning from these is removed.

This system has several disadvantages. It is much more expensive and more complex. This mean that if it needs to maintained for some reason, it is more difficult to access the pipes. Temperature changes can cause the pipes to change size, which may cause the system to stop working or be damaged. This is normally solved by simply re-pressurizing the system.

Different kinds of geothermal flow centers exist, and one can decide between the two main types. Those which are pressurized are expensive, but they’re less likely to have complications and have a more organized operating system. Non-pressurized versions are cheaper, but tend to get leaks more often and are more fragile. If one wishes to have an efficient water heater, considering these facts can help them decide what is right for them.
