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.
