Radiant and Snowmelt Applications

1. Determine the heat load for the application

2. Determine the supply temperature and flow for your system

3. Using the charts below, determine what domestic temperature and top coil flow combination will

satisfy the space heat demand.

4. Choose either the DC-80 or DC-120 based on the domestic hot water load. Specify double-wall

heat exchanger if required by code.

Example: Radiant loop for large addition

80-gallon unit selected to handle large bathtub

120°F desired supply temp

45,000 BTU anticipated heat load

In this example, a domestic water setting of approximately 138°F will provide a

consistent 120°F output at 4GPM.
