What are the drawbacks to closed loop systems?
Cost is the main drawback to closed loop systems. Drilling can be expensive in some areas of the country. What about using an open loop instead of a closed loop? Open loop geothermal systems have been used for years. Many areas no longer allow open loop geothermal systems saying they are bad for the environment since they may delete water supplies. Open loops are actually a great source of heat transfer since ground water stays relatively the same temperature year round. What are the drawbacks to open loop systems? The main drawbacks are the amount of wasted water since 6 – 9 gallons is normal for an open loop system. Possible mineral deposits can ruin a geothermal system causing major repair bills. How hard is it to install a geothermal system? The difficulty varies from home to home. New construction is the easiest as long as there is coordination between the homeowner, the builder, and the mechanical contractor. Space is the only real drawback to installing geothermal equipment sinc
