Berekening Verwarmingscapaciteit

With the table below, you can easily make a calculation for heating a standard production hall.

Starting points and points for attention:
  • Daylight in wall and/or roof approx. 15%. Floor construction concrete on sand.
  • Take into account extraction systems, scaffolding and crane gantries.
  • Consider the number and position of service doors.
  • Note any heat gains from machinery and lighting.
  • All capacities (in kW) apply at an indoor temperature of 15°C and an outdoor temperature of -10°C.
  • For each degree Celsius more or less, the output must be corrected by 4.0%.

Richtlijnen Opstookprotocol

This warm-up and cool-down protocol should preferably be carried out several times before installing a floor covering or finish (plastic floor, tiles, flagstones, parquet, laminate, marmoleum, etc.).
In this warm-up and cool-down protocol, underfloor heating means a hot water pipe embedded in a floor. The floor should be at least 25 mm thick above the water pipe.  

Cracks can appear in screeds with underfloor heating due to thermal length changes. To minimise this risk, the underfloor heating should be warmed up slowly and regularly. It is advisable to apply the warm-up and cool-down protocol below. A warm-up and cool-down protocol for underfloor heating is based on the water temperature of the heating system and not on any thermostat temperature in the room in question.


The Mollier diagram (also called enthalpy-entropy diagram, h-s diagram or psychrometric diagram) is a diagram designed by Richard Mollier in 1904 in which enthalpy and entropy are plotted. Such diagrams are used in steam turbine design, refrigeration engineering, weather forecasting and air drying systems for the food industry, cold store and freezer cell calculations, among others.
