Yes, many factors determine the heat loss. What you are saying is that a larger surface area will emit more heat (at the same temp), and so if one wants more heat output, one might use a larger pipe or radiator. This is correct. However, what I am saying is that the amount of heat loss is...

For a given volume, pipe size will affect the flow rate in metres/second (and other things like the head loss etc), but for the heat calc all you need is volume of water per unit time and the temperature change. In other words, if you joined a 22mm copper pipe to a 10mm plastic pipe (so they...

pappasmurf, the heat output of a pipe, like any other radiator, depends on the insulation around it and the temperature difference between the pipe and the surrounding materials. When you buy a radiator, the quoted BTU is an approximation based on assumptions of water temperature, the air...
