COMPLETE DESIGN TOOLS IN A SMALL PACKAGE
The RadPad Sizing Calculator is a powerful tool for quickly and easily answering complex "what if" questions to radiant floor heating system design problems.
SIDE 1 - Answers these questions
- What floor Surface Temperature will be required to heat my space?
- What Water Temperature will be required at design loads?
- What is the maximum Floor Covering R-Value I can use on the floor?
- What happens if I increase the Floor Covering R-Value?
- What happens if I increase the water temperature?
- How can I get more output from the floor?
SIDE 2 - Answers these questions
- What Tube Size should I use?
- What Tube Length is best?
- What Tube Spacing will give the best output?
- What will be the Flow and Head Pressure for pump sizing?
- What happens if I use longer tube circuit lengths?
- How can I reduce head pressure?
- What happens if I use a larger tube?
- How does changing tube spacing affect floor output?
Our Excel Spreadsheet Workbook allows you to input your design information step by step and does some of the calculations for you.
