Are heating appliances compatible with salt water chlorination?

For the last 20 years, Zodiac has been using a patented technology associating polyamides and titanium, both of which are totally free from the effects of corrosion. Today over 120,000 appliances have been installed without any corrosion defects. If a salt water chlorination method is being used, it may be important to install a check valve between the heater outlet and the salt water chlorinator, to prevent high concentrations of chlorinated water from back siphoning into the heater.

Must my pool be covered (cover, rolling shutter...) or sheltered if it is to be heated?

No, it is perfectly possible to heat an "open air" pool without a cover or a shelter. The power and fuel requirements is similiar to heating a house with the windows open! This is why we recommend the use of an insulating cover to limit heat loss to the open air when the pool is being heated. A covered or sheltered pool will reduce the heater power and fuel costs.
