This supports stable comfort, improved seasonal efficiency and reduced noise during normal running, especially when used together with a pool cover.<\/p>\n<h3>Heating and cooling for season control<\/h3>\n<p>Because the UX21Csi32 is reversible, it can heat the pool in cooler months and cool the water during hot periods.
