I need to import data from a csv file, which contains hourly temperature data in a year (8760 values in one column), in order to create a 24x365 matrix to make a heatmap like the image

Try this —
T1 = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1088620/results.csv', 'VariableNamingRule','preserve')
Hours = reshape(T1.Hour, 24, []);
T_del_C = reshape(T1.('T delivered (C)'), 24, []);
xv = datetime(2021,1,0, 'Format','MMM') + days(1:size(T_del_C,2));
yv = Hours(:,1);
figure
surf(xv,yv,T_del_C, 'EdgeColor','none')
colormap(turbo)
view(0,90)
axis('tight')
It comes reasonably close to the plot image in the original post.
Make approopriate changes to get the result you want.
