Solution
PARAMETERS TAKEN INTO ACCOUNT WHEN DESIGNING A SYSTEM AND CONSTRUCTING
- Arrangement and size of radiant heaters - larger surface area of a 地面供热/供冷区 enables lowering supply temperature.
1. Size of 地面供热/供冷区
更多信息，见： 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.最大长度 - Perimissible pipe spacing - has effect on mean surface temperature of radiant heater.
3. Pipe spacing - Insulation thickness under radiant heater - has effect on 辐射供热的热损失（向建筑之外）.
4. Insulation layer - Selection of proper 装饰层 in rooms - has effect on radiant heater efficiency and on uniform temperature distribution on heater surface.
5.装饰层

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)
6. Supply temperature
更多信息，见： Modifying system parameters to adapt attained output to required output - Maximum flow rate in floor heating loops - possible by adjusting Δθ 最小 内区, Δθ 最大 内区, Δθ 最小 外区 and Δθ 最大 外区 or by specifying 供回水温差.
7. Parameters that have effect on maximum flow rate in floor heating loops
