Experimental Comparison of Heating Emitters in Mediterranean Climate
Round 1
Reviewer 1 Report
This paper is overall interesting to investigate indoor temperature variations with the use of different heating methods. Overall, this paper is sound, but it can be improved in:
1 The introduction is too long to read. Authors have not presented a sound and scientific research aim and objectives
2 The title of this paper 'water emitter', should be revised. Moreover, authors have not directly indicated the comfort thing so that title should be improved.
3 How to consider the irregular value in Figure 11 and Figure 12?

Reviewer 2 Report
# Comment 1:
The paper is well written, however, it is suggested that a native English speaker checks the English of the paper. The contents of few paragraphs are unclear, and some terms like “the figures” are not correct.
# Comment 2:
Please revise the abstract. The stated problem and solutions are not connected to the findings of the paper. The research gap is not also clear.
# Comment 4:
The introduction is relatively long. The literature review is not satisfactory, as the unique contributions provided by the paper are unclear. The introduction is started with a very general problem. The research gap(s), general problems, specific problems, general solutions, specific solutions are not clear. Unfortunately, the gap that the authors mentioned does not represent a research gap in this context. Experiments with few days may not represent the Mediterranean climate conditions.
# Comment 6:
A critical point of the reviewer is the calculation of PMV for the case. It is highly suggested to justify the application of PMV based on reputed citations for the comparisons.
Additionally, a floor heating system directly influences local comfort/discomfort of the lower body and subsequently, it can also influence the overall thermal comfort perception of occupants. In contrast, the fan coil unit creates a layer of conditioned air aground the body. Therefore, it is not accurate to compare the two systems and their effect on the comfort level based on the operative temperature. This comparison would be valid if there would be subjective votes corresponding to these systems.
# Comment 7:
The quality of the building envelope influences the uniform condition and thermal comfort conditions. It is highly suggested that authors argue the building quality for the comparisons between the scenarios.
# Comment 8:
The effect influence of systems particularly the floor heating system on thermal comfort conditions can be explained by the surface temperatures. Are the surface temperatures available?
