TwoRelax supplies Wellis hot tubs that are compatible with UV sanitation systems and salt chlorination as alternatives to traditional chlorine dosing. These systems reduce chemical loading by 60–80%, making the water gentler on skin, eyes, and hair — while maintaining full sanitation compliance. Contact TwoRelax to discuss UV or salt system integration with your Wellis model.
What Is a UV Sanitation System and How Does It Work?
A UV-C sanitation system passes circulated water through a UV light chamber (typically 25–30 mAh) that destroys bacteria, viruses, and algae at the DNA level — without adding chemicals. UV systems reduce chlorine demand by 70–80%, meaning the water requires only minimal residual chlorine (0.5–1.0 ppm vs. the standard 3–5 ppm). The result is water that is odour-free, non-irritating, and gentle for daily use.
What Is a Salt Chlorination System?
A salt chlorinator passes low-salinity water (3,000–4,000 ppm — similar to human tear ducts) over an electrolytic cell that continuously converts salt into hypochlorous acid (the active sanitiser). This auto-generates chlorine on demand, eliminating the need for manual dosing. The water feels soft and skin-friendly rather than chemically harsh, and chloramine odour (the "swimming pool smell") is absent.
How Do UV and Salt Systems Compare to Traditional Chlorine?
| Factor | UV System | Salt System | Traditional Chlorine |
|---|---|---|---|
| Chemical feel on skin | Minimal | Very gentle (soft water) | Can cause irritation |
| Odour | None | None | Chloramine smell |
| Manual dosing needed | Low (residual only) | Minimal (pH balance only) | Weekly/bi-weekly |
| Annual running cost | ~€80–€150 (lamp + minimal chemicals) | ~€50–€100 (salt + pH) | ~€200–€350 (chemicals) |
| Best for | Sensitive skin, allergy sufferers | Daily use, families | Standard use |
Are UV and Salt Systems Compatible With All Wellis Models?
UV systems can be retrofitted to most Wellis models via the existing circulation system plumbing. Salt chlorinators require a compatible cell fitting — TwoRelax can confirm compatibility with specific models before order. Both systems work with the Wellis control panel (Easy4, Easy7, or SmartTouch) and do not affect warranty coverage when installed by a qualified technician.
What Are the Benefits of Gentle Water Care for Family Use?
- Children have more sensitive skin and eyes — lower chemical exposure reduces irritation risk
- Older users or those with skin conditions (eczema, psoriasis) benefit from reduced chloramine contact
- Hair and swimwear are less damaged by low-chlorine water
- Water chemistry stays stable longer, reducing maintenance frequency
- Soft salt water is more comfortable for extended daily sessions
