The heat loss diagrams below is based on metal pipes with fiber glass insulation with thermal conductivity 0.25 Btu/h ^oF ft²/in, outdoor condition with moderate wind 20 mph. A safety factor of 10% is included.

indoor location - reduce values with 10%
mineral wool insulation - increase values with 6%
rigid cellular polyurethane - reduce values by 30%
