What is a fan coil?

Fan Coil - (FROM WIKIPEDIA) A fan coil unit (FCU) is a simple device consisting of a heating or cooling coil and fan. It is part of an HVAC system found in residential, commercial, and industrial buildings. Typically a fan coil unit is not connected to ductwork, and is used to control the temperature in the space where it is installed, or serve multiple spaces. It is controlled either by a manual on/off switch or by thermostat

I have always used 20 BTU/ft2, for designing; unless then house is obviously under-insulated or has excess load, but never designed to more than 35 BTU/ft2.
HOWEVER, if you look at SnowMelt application 150-200 BTU/ft2 is not uncommon

LittleJohn,

I use water to air heat exchangers 98 % of the time. I also use minimum of 45 btu's per sq. ft. and I do not have a unhappy customer.

Different applications, different BTU loads 

As long as the customer is happy I guess it must be working

A lot depends as well on your area of the country, I'm sure the frigid north is going to need more BTU's available for those -40 times than somebody living in Tennessee.

In Tennessee don't you just light a candle in every room to stay warm
