Thermal and hydraulic results improvement by adjusting structural and operating parameters of a radiant system heater.

PARAMETERS TAKEN INTO ACCOUNT WHEN DESIGNING A SYSTEM AND CONSTRUCTING
- Arrangement and size of radiant heaters - larger surface area of a Heating/Cooling Floor Zone enables lowering supply temperature.
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.
- Perimissible pipe spacing - has effect on mean surface temperature of radiant heater.
- Insulation thickness under radiant heater - has effect on Losses of radiant systems to outside of source feed area.
- Selection of proper Covering in rooms - has effect on radiant heater efficiency and on uniform temperature distribution on heater surface.

PARAMETERS THAT CAN BE SET/ADJUSTED IN COMPLETED SYSTEM
- Supply temperature, if a system with adjustable temperature is used (e.g. gas-fired water heater with a mixer or a mixing pump set)
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.
