Comfort Systems has found over the years that people have a lot of questions about geothermal heating and has created a list of FAQs of the most commonly asked questions.
Let’s start by explaining what geothermal heating is and the two different types. There is high-grade and low-grade.
High-Grade Geothermal Heating
The heat of the earth’s pressure that transforms water into steam is known as high-grade geothermal energy.
Low-Grade Geothermal Heating
The heat within the earth’s crust is known as low-grade geothermal energy. The heat is solar energy that has been stored.
Q – What Does It Mean to Have an Enhanced Geothermal System?
A – A man-made water source called an enhanced geothermal structure is built when hot rock exists, but natural conductivity or water saturation is insufficient or minimal. Conductivity is created in the subsurface by injecting fluid into previously closed cracks under precisely controlled circumstances.
Q – Can a Geothermal Reservoir be Depleted?
A – For decades, geothermal energy output has been examined and evaluated for its long-term environmental viability. As reservoir pressure drops, operators have started re-injecting water to keep reservoir pressure stable.
Q – What are the Environmental Benefits of Geothermal Energy?
A – Emissions are low. In geothermal flash plants, just the surplus steam is discharged. Binary geothermal factories, which are expected to overtake existing technologies in the near future, emit no gases or liquids.
There are several ways that salts, and minerals dissolved in geothermal fluids can be pumped back into the reservoir. The reservoir gets replenished because of this process.
The Geysers power plants in Santa Rosa, California, employ reinjection fluid from the city’s treated wastewater. To extend the reservoir’s life span, this technology recycles the disinfected wastewater.
Some geothermal facilities do create solid wastes, or sludges, that must be disposed of in designated locations. Sulfur, silica, and Zinc sulfur, for example, are some of the lucrative and ecologically favorable solids that are increasingly being removed for sale.
Q – What Makes Geothermal Energy Renewable?
A – Because it comes from the Earth’s core, which generates a near-infinite quantity of heat. It is possible to use geothermal energy in locations that rely on a pool of hot water, making it a renewable source of energy.
Q – This is due to the fact that the Earth’s core produces a virtually infinite quantity of heat. It is possible to use geothermal energy in locations that rely on a pool of hot water, making it a renewable source of energy.
Q – What Type of Upkeep Can I Expect?
A – As long as the air blower and air blower filter component are routinely serviced, a correctly fitted closed-loop pump needs little to no maintenance. Open-loop heat exchangers require regular water coil maintenance since water quality can have a significant impact on the heat exchanger’s performance.
Q – Does it Improve the Air Quality?
A – Yes. All-electric heat pumps emit no combustion products; thus, they do not pose a threat to the interior air quality. The dangerous carbon monoxide and other harmful gases must be vented from conventional gas and propane systems through chimneys.
Q – Is It Possible to Heat My Home’s Hot Water Using a Geothermal Heat Pump?
A – A heat pump may provide domestic hot water for as little as a few cents a day or even for free. Hot water desuperheaters are meant to extract heat from the coolant gases that are contained in a heat pump’s condenser.
When it comes to home water demands, a basic hot water desuperheater can deliver up to 120 degrees Fahrenheit water. These heat pumps can save money on hot water for industrial buildings with substantial hot water needs.
Q – Does My Electric Service Need to Be Increased?
A – The majority of residences currently have ample power. It is appropriate both residential development as well as retrofitting installations because of its low energy consumption.
Q – Where Will the Pump Be Located?
A – Heat pumps are found within buildings. For a variety of reasons, this is enticing. Allowing for improved building and yard utilization, inside installations free up outside space. the electric controllers and heat transfer coils are shielded from the weather, the outdoor condensers have a longer life expectancy.
Q – Does it Melt Snow?
A – Yes. An increasingly popular feature is the ability to use geothermal energy to melt snow from driveways and walkways.
Q – How Long Should I Expect the System to Last?
A – Ground-source heat pumps are likely to last between 18 and 23 years, according to experts. As compared to traditional systems, this is approximately twice as much.
