People often measure the comfort in a building by the indoor temperature. Therefore it is important to know if enough heat is generated and if too much heat is not lost. Henco has developed a handy tool to calculate the heat loss. Please fill in the requested data below. Then fill in your email address and press the Send button. The result will also be sent to your mailbox so that you can consult the result at a later time. If the heat loss is too high, adjust the values in the fields and calculate the heat loss again.

Heat loss/gain tool

Calculations are made based on ISO 12241:1998, for horizontal or vertical pipes inside a building (laminar free convection).
Outer layer of the insulation has high emmisivity = 0.90
Always take into account a large safety margin as practical circumstances may deviate from calculation assumptions.
