	This paper examines the viability of using a radiant panel in lightweight low-height floor heating. In this structure, a dry screed with high thermal resistance is replaced by a low-resistance adhesive layer with reinforcement mesh. The absence of the radiant panel results in a reduction in heat output of 5%–17% for floor finishes with a thermal resistance of 0.001 m2K/W, 50%–54% for 0.05 m2K/W and 60%–62% for 0.1 m2K/W. A structure with a panel is characterised by a lower surface temperature amplitude (maximum 2.4 K) compared to a structure without it (8.8 K), which improves the comfort of floor users. The annual heating cost in a building equipped with the analysed structures was determined. The absence of the panel resulted in a cost increase of 13%, 37% and 79% for floor finish resistances of 0.001, 0.05 and 0.1 m2K/W, respectively. The SPBT for the purchase of radiant panels is 40 years for a floor resistance of 0.001 m2K/W, demonstrating the unprofitability of this solution. For resistances of 0.05 and 0.1 m2K/W, SPBT was 14 and 6 years, respectively. The choice of floor heating system should take into account the required heat output, thermal comfort and economic aspects.
