Can I plant trees over my geothermal loops?
Can you plant trees over the area where ground loops are installed? We would not recommend planting trees over where ground loops are installed for 2 primary reasons: Tree root systems can grow into the loops. It may be difficult to repair or add to the piping system without damaging the tree.
Can you build on top of geothermal lines?
Yes. But it requires some foresight. Keep the footings away from any freeze/thaw basically.
What can go wrong with geothermal heating?
Leaks. The refrigerant or water can leak from the underground or underwater pipes in geothermal heat pumps. This is similar to the way refrigerant can leak from the coils of a conventional heat pump. Your home could feel less comfortable, and you may notice ice or frost on the above-ground part of your unit.
What are bad things about geothermal?
There also some *cons* when it comes to geothermal energy: High costs to construct geothermal plants. Sites must be located in prime areas, requiring long distance transmission, which is often costly. The introduction of water is considered wasteful and possibly harmful to the environment.
How do you install a ground loop geothermal system?
Horizontal Ground Loop Installation To install a horizontal system, workers utilize trenchers or backhoes to dig trenches 5-10 feet below ground and then install a series of plastic pipes that comprise the geothermal heat exchanger. They will then backfill the trench, taking care not to allow sharp rocks or debris to damage the pipes.
What is the best material for a closed loop geothermal system?
High-density polyethylene (HDPE) and crosslinked polyethylene (PEXa) are the only materials formally approved for closed-loop geothermal systems by the International Ground Source Heat Pump Association (IGSHPA).
What are the different types of geothermal systems?
There are several types of ground loop designs that can be made, but they all fall under two basic categories: closed loop and open loop. There are 3 types of closed loop geothermal systems: vertical, horizontal, and pond / lake.
What are the disadvantages of geothermal energy?
Geothermal energy has high initial capital costs. May release harmful gases. Suited to a particular region. Geothermal heat pumps have to be powered. Geothermal sites may experience a dry spell. Sustainability issues. Can cause surface instability. Extremely high temperatures required.
