Doesn water get warm around the pressure pump by sitting inside the machine?
Radonett has a built-in pump of the same type which lies in the lower region of the water in the boring hole (lower pump). Your boring hole pump doesn’t actually warm up the water and neither does the Radonett built-in lower pump. A built-in lower pump is significantly more effective than external ring pipes. An effective radon aerator has a shorter processing time and thus, does not warm up the water. Radonett is in operation only when the hydrofor/hydropress fills up, not the whole day.
