Reverse Return Piping Diagram Geothermal. Each circuit displays a distinctive voltage condition. You are able to easily step up the voltage to the necessary level utilizing an inexpensive buck boost transformer and steer clear of such issues. The voltage is the sum of electrical power produced by the battery.
Reverse return piping was developed to help achieve this goal. Figure 1 shows a simple representation of reverse return piping through two identical components, each in its own branch piping. . . . When — and when not — to use reverse return piping.
Perfect example of Reverse Return Geothermal Piping. This feature is not available right now. Please try again later.

Most of the required heat in a heat pump system comes from other heat pumps on the loop operating in cooling. The actual number of hours a Boiler Tower loop requires supplemental heat is very small. In the example in Figure 1, the boiler actually ran only 1506 hours, mostly on weekends.
*A borehole is a narrow shaft bored in the ground. **Closed loop systems are typically more expensive to build and less energy efficient than Standing Column Well systems. Here is a diagram of a typical Closed Loop Well geothermal system utilizing a reverse return piping layout.
If the discussion is that or reverse return, I would say close header is your answer. The only time we do RR is if it is engineered that way, or I can not meet IGSHPA's reccomendation for the plus or minus 10% on total loop length for balancing. We have modified our thinking and pricing over time due...
A direct return system requires less main piping, but because flow will be uneven (favoring the front terminals), the system will require manual or automatic balancing valves. Reverse Return. A reverse return system is routed to be the opposite of a direct return: the first terminal in the supply is the last terminal on the main and vice versa.
A vertical closed loop geothermal wellfield typically consists of multiple vertical heat exchangers (VHEs). VHEs are constructed by drilling holes generally ranging from 50to 400 feet deep in the earth and then inserting two pipes with a fitting joining the two pipe ends at the bottom (called a u bend pipe assembly).
