Right-Loop

Residential Geothermal Loop Design

Right-Loop™

Requirements

Either Right-J®, or Right-F280™

Geothermal Design Worksheets:

Right-Loop™ provides quick, easy and accurate geothermal loop designs that comply with all industry standards. Based on methods developed by the OSU Design Manual for the general method, ASHRAE Design Manual for fundamental calculations, Cavanaugh/Alabama for lake/pond calculations, and NRECA/OSU/EPRI for Slinky calculations. Right-Loop™ supports multiple single pipe and multi-pipe applications for trenches and wells, and supports a variety of antifreeze options including Propylene Glycol, Methanol, Ethanol and Potassium Acetate (Cryotech GS4 or equivalent).  View overview video.

Features:

Right-Loop™ is the digital version of the geothermal design worksheet. This program will design your geothermal system instantly, once the data set is completed. Right-Loop™ requires you to set your bin data and earth temperature cities, select your ground-source heat pump equipment and circulating pump, and set your equipment configuration and loop characteristics. (Right-Loop™ contains diffusivity and conductivity numbers for both ASHRAE and EPRI earth types, and supports custom diffusivity and conductivity from soil testing.) Once this is done, the program will do the calculations automatically.

Use Right-Loop™ to:

Size ground loops for residential geothermal systems.

Design the loop to meet the rated capacity or a targeted entering water temperature.

See the effects of using different loop lengths.

Maintain a customizable Reynolds Number minimum.

Utilize a built-in pump sizing worksheet.

Additional Technical Features

  • Handles parallel, series, horizontal and vertical loops, slinky and pond configurations
  • Computes water and anti-freeze volumes with Reynolds number (and a customized Reynolds number warning) for easy mixing for Propylene Glycol, Methanol, Potassium Acetate (GS4 or equivalent), water, and more.
  • Load calculations from Right-J® and Right-Draw® are read into Right-Loop automatically
  • Select equipment from a library, then pick the loop type and configuration
  • Extensive built-in library of tabular data, such as bin weather, earth temperature, and soil types (with those selected, Right-Loop calculates the remaining factors instantly)
  • Everything you need is built-in with Right-Loop
  • Full multi-zone capability allows one loop per zone or combined equipment on loops
  • Calculates the pump head and freezing temperatures for variable antifreeze percentages
  • Extensive picture library of loop configurations
  • Includes ground source equipment
  • Graphic display of loop length vs. EWT

Benefits:

Right-Loop™ is a fast, easy and accurate way to design your geothermal system, without the mental gymnastics of a manual Geothermal Design Worksheet.

Testimonials

What Our Customers Are Saying

"As a business owner, one of the things I like is that Right-Draw gives us a level of professionalism whether it’s a specialty home or a basic starter home. Within the past year, we have actually picked up new accounts because our customers were so impressed by the professionalism of our designs, particularly when we go up against contractors who are giving them what amounts to a crayon rendition on a napkin."

Mike Douglas

from Advent Air Conditioning

"I’ve always been a proponent of proper sizing of air conditioning equipment. For a standard 3,000 square foot, 4 bedroom house, doing the load calculations manually would take many hours. Then I found Wrightsoft, and by using their Right-J and Right-D, I was able to produce load calculations and duct design in about an hour."

Bob Pietrangelo

from Comfort Solution

“Hands down, the best tool for the job. Our HVAC partners love the 2-line mode drawings, and the export to REM/Rate module saves me at least 2 hours per project! That's a real game changer for us in terms of billable hours and revenue. Mike (sales) and Donald (tech support) have been there for us for over 10 years! Keep up the good work and thanks again guys. - Just another loyal happy customer.”

Mike Truitt

Resnet Rater from This Efficient House

“We are primarily a residential replacement air conditioning and heating company in Clearwater, Florida.  We found a serious issue with improperly sized air conditioning systems in existing homes that was causing issues with humidity, or lack of cooling.  We have used Manual J for over 30 years, but due to the time-consuming process of entering information manually, it was not done unless we had a consumer complaint.  We partnered with Wrightsoft over 15 years ago and can now do a Manual J Load Calculation in less than 30 minutes. Wrightsoft is always there for us, with tech support staff that answers the phone quickly, and offer advice when needed.  There is also a library of how to videos available 24 hours a day on their website. Wrightsoft has continued to be the best option for us for Manual J load calculations.”

Jim Heinz

President of Heinz Air Conditioning and Heating, Inc.

“I reached out to technical support [to complete an advanced task].  [Technical support] responded within an hour or two, guided me through the process, and even QC’d my spreadsheet (making corrections needed).  I was really impressed… I’ve found that my questions are always answered, usually within hours, and there’s never an attempt to dodge an issue. Wrightsoft’s responsiveness on the support side is what truly sets you apart.  Your team has made my life easier and using RSU has become an integral cornerstone to the work I do guiding our teams in the design and construction of high performance, soon to be ZNE affordable housing.”

Tim Kohut

Director of Sustainable Design National Community Renaissance

“I've been using Wrightsoft since the late 80’s. Public Service Company in Oklahoma's "Good Cents" program required an ACCA Manual J load calculation and ACCA Manual D duct design to qualify as a "Good Cents" structure. As long as the information is entered correctly, Wrightsoft takes all of the guesswork out of the equation. It has given me peace of mind and keeps our quality of installation above the rest. I can't imagine doing an install without it, it's as important to us as the rest of the tools on our trucks.”

Steve Paxton

from Air-Dynamics

“The Wrightsoft experience has been great from the beginning to end.  Their support staff are patient and professional.  Proper equipment sizing is imperative regarding our customers comfort. We have been able to provide our customers with accurate professional data to backup our proposals awarding us multiple projects over our competitors. Well worth the investment of time and money.”

Tom Tumminelli

from Brothers Plumbing, Air & Electric

"If you're a Wrightsoft user and have been wanting to go to the next level, Right-CAD is it. I'm not conversant with CAD but I was up and running with 3D almost immediately, importing some of my more complex duct designs already created with RSU, and amazed at seeing what I could only imagine before. The 3rd dimension takes the guesswork out of interstitial duct runs, navigating dropped ceiling areas, dropped girders, etc. Learning curve is simplified by utilizing the familiar tools & tabs already within RSU, and yet with lots of bells and whistles for rainy day exploration and further fine tuning of design presentation. I see this as the future of professional & field ready HVAC design, without the cost and lengthy learning curve of Revit."
