Radiant heating systems - how to improve thermal and hydraulic results

Problem description

Thermal and hydraulic results improvement by adjusting structural and operating parameters of a radiant system heater.
For more information, see: Design of radiant heating floor and wall installation

Arrangement and size of radiant heaters - larger surface area of a Heating/Cooling Floor Zone enables lowering supply temperature.

1. Size of Heating/Cooling Floor Zone

For more information, see: Heating/cooling_zone
Maximum attainable supply temperature when heat pump is the source.
Maximum loop length - has effect on flow resistance and manifold size, and thereby also on operating and capital costs.

2.Max. L
Perimissible pipe spacing - has effect on mean surface temperature of radiant heater.

3. Pipe spacing
Insulation thickness under radiant heater - has effect on Losses of radiant systems to outside of source feed area.

4. Insulation layer
Selection of proper Covering in rooms - has effect on radiant heater efficiency and on uniform temperature distribution on heater surface.

5.Covering

Supply temperature, if a system with adjustable temperature is used (e.g. gas-fired water heater with a mixer or a mixing pump set)

6. Supply temperature

For more information, see: Modifying system parameters to adapt attained output to required output
Maximum flow rate in floor heating loops - possible by adjusting Δθ min OZ, Δθ max OZ, Δθ min PZ and Δθ max PZ or by specifying Temp. diff. supply-return.

7. Parameters that have effect on maximum flow rate in floor heating loops
