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?
