Mears - First Principles Calculator

[professorplumb]

Rad sizing i bought the first principles calculator and have lost the instructions within a few days of having them. Does anyone use it that can give me a run through seems a good bit of kit.

Also is there a list of U-values i can print off and keep with me for when i go along and size the rads. will need the values for walls, doors, windows etc

thanks

Simon

try going in to the shop you got it from and say if had no papers in side.
they may get the sheets from another box
that may work


good luck mate
