FreshWater Pool Systems FAQ
Frequently Asked Questions
1. Can a freshwater ozone system work with a heated pool?
Yes. Freshwater ozone systems, including those with twin corona discharge and low-level chlorine cells, are fully compatible with heated pools. Heated water increases chemical activity, so correct setup and ongoing monitoring are important to maintain water clarity and equipment longevity.
2. How is a freshwater ozone system different from a saltwater pool?
Unlike saltwater systems, freshwater ozone systems operate at low TDS (~1200), produce only a small amount of chlorine, and rely on ozone oxidation for sanitisation. This reduces corrosion risk, equipment wear, and ongoing chemical costs.
3. Do I still need chlorine with a freshwater ozone system?
Yes, but only a small amount. The integrated chlorine cell provides residual sanitisation, while the ozone system does the heavy lifting to reduce chemical reliance. This keeps water clean and safe without excessive chemical use.
4. What are the benefits over competitors like Naked or Enviroswim?
Many competitors rely on high-cost consumables or intensive chemical top-ups, which are rarely highlighted upfront. Freeheat systems minimise consumables, operate efficiently at low TDS, and reduce long-term maintenance and running costs.
5. Can I upgrade my existing pool to a freshwater ozone system?
Absolutely. Existing pools, whether saltwater, chlorine, or older ozone setups, can often be upgraded. Proper design ensures compatibility with your current heating and circulation systems, improving water quality and performance.
6. How long do freshwater ozone systems last?
With correct installation, maintenance, and water balance, the equipment can last for many years. Operating at low TDS reduces corrosion and wear, particularly when integrated with heating systems. We use a twin corona discharge patented technology with a ten year warranty.
7. How much maintenance is required?
Freshwater ozone systems regular water balance checks are recommended, routine inspections every 2 years, and occasional cell replacement in maybe 6 to 8 years. Compared to traditional salt systems, maintenance is typically simpler and less costly over time.
8. Is this system safe for swimmers?
Yes. Ozone is fully dissolved in the water and leaves no harmful residues. The small amount of chlorine generated by the cell provides additional protection, keeping water safe and comfortable for swimming.
9. Will this system reduce my pool’s running costs?
Yes. Reduced chemical use, lower TDS, and minimized equipment wear contribute to lower ongoing costs, particularly when compared with high-consumable chlorine only, fresh water ionised systems or saltwater pools.
10. How do I know if a freshwater ozone system is right for me?
If you want a heated pool with clear, low-chemical water, longer-lasting equipment, and lower maintenance costs, a freshwater ozone system is an excellent choice. Freeheat can assess your current pool setup and recommend the best configuration.
