Vic, It's actually a new unit heater, only been in use for about 2 weeks,
coil looks good and clean. The heater seems to push out a good amount of
heat but not quite enough to overcome the heat loss from the building..

Before you start hackin and whacking

One question

Are the fins on the coil clean...you never indicated how old or how long
this
unit had been in service.

If the fan is running with your really low delta t between supply and
return
and lack of heat from the heater; a good cleaning may be in order

Or it could be one of maybe 48,345 things
but have fun
