Answer the following statement(s) true (T) or false (F)
1. The heat output of a fan-coil is approximately proportional to the temperature difference between the entering air and entering water. 2. The rate of heat transfer depends on either the temperature difference or the flow rate. 3. Panel radiators typically require much more wall space than fin-tube baseboard sized for equivalent heat output and operating conditions. 4. Reverse return piping encourages equal flow rates and equal supply temperature to each radiator. 5. A rule of thumb is to allow twice the linear footage of radiant baseboard compared to typical residential finned-tube baseboard.
