So, when you say 30C (86F) max temp, you are talking about 30C being the temperature of the water going into the hydronic floor, right?
I agree that this would be a highly desirable temperature as regards your ASHP efficiency.
I wonder if you could go into some detail regarding what your understanding is of the house insulation and tubing requirements to make this happen.
Also when you say that the COP would then be acceptable, what in your opinion would be an acceptable COP in this case.
Thanks,
