Reduce bills and sustain year- round heating with the highly efficient Dura Pro heat pump. Using inverter technology, Dura Pro can heat water to 40°C, and maintains the temperature while using a lower current — saving energy and electricity costs. It even operates in outside conditions as cold as -15°C. The unit’s unique ventilation structure means noise levels are kept extremely low so as not to disturb guests. Dura Pro is built to last, benefitting from titanium heat exchangers that are highly resistant to corrosion by salt, chlorine and bromine. The Dura Pro heat pump is available in 5 model sizes catering to a variety of pool and hot tub installations.
