Can I use it in warm water?

Yes! Spectra Watermakers will work in warm water.

Spectra Watermaker will work extremely well in warm water. The power consumption may even be lower than normal.  All of our systems are designed to be inherently self-balancing, so at the water temperature rises, there is no need to make any adjustments to your watermaker at all.  Just start the system up and enjoy the water at its full rated capacity.
