When is this calculator suitable?

This calculator is very easy to use and also very handy at the same time. You can resolve basic heat power requirement tasks in a few seconds.

You can use the calculator for hot water boilers, water and air heat exchangers, hot water radiators, water chillers, air heaters, and other heat power generation and consumption units.

What has to be known for a calculation?

You can select between two calculation scenarios. The first is heat power calculation, and the other one is the flow rate calculation.

In both scenarios, you have to insert the specific heat of a fluid as well as temperatures on the start and the end of the heat exchanger.

You can also select between volume and mass flow rate, for a known density of the fluid. The calculator displays the velocity of the fluid for entered pipe internal diameter.
