Salt water hot tubs produce chlorine through a technique known as electrolysis. In a nutshell, rather than adding chlorine right to the spa, you include salt that the system uses to make chlorine. While the mechanism may differ, the outcome would be the same — chlorine from the water, killing bacteria and algae.In reality, salt water systems can also be referred to as salt water chlorinators or salt water chlorine generators. If you do not observe these terms much, it’s likely because manufacturers do not like to market the fact that chlorine is demanded.
Salt water hot tubs are a great but jarring alternate. The hot tubs themselves are identical – only the method of sanitation differs. So what is the difference, you wonder? Keep reading to discover more about the advantages and disadvantage
Saltwater hot tub pros
- Increased comfort – Saltwater hot tubs contain less chlorine, resulting in a more comfy soaking experience. The huge majority of people who opt for saltwater tubs do this for the higher comfort.
- Less Odor – Chlorine tablets smell bad from the bucket, and bad in the spa. Bromine is a little bit better, but I can still smell it on my skin and on my own hair, hours. Have you ever opened up your spa cover and discovered the strong smell of chlorine? That is the smell of combined genes, chloramines or bromamines. Salt systems are not as inclined to create those dirty smelling mutations of chlorine, since after a chlorine molecule is consumed, it reverts back to salt, or sodium chloride!
- But to be honest, a great deal of the bad experiences people have with chlorine-treated swimming pools and spas are likely because of poor maintenance — not the chemicals themselves.
- No chlorine to buy – The generators in saltwater hot tubs produce their very own chlorine, which means you will not ever have buy, lug or add chlorine to the tub
- Maybe the best advantage of a saltwater hot tub, is that you no longer need to store bromine or chlorine tablets, which might be dangerous. You should still shock the spa, so maintain a cohesive oxidizer on hand, but you also can utilize chlorine free MPS if you prefer. Spa salt systems make their own chlorine, therefore it is still a chlorinated health club, but it is created naturally, and is without binders or additives — pure chlorine.
Saltwater hot tub cons
- Warm Water Just – Salt systems, for pools or spas, have trouble generating chlorine in low water temperatures. When water temperatures drop into the 60’s, hardly any chlorine result is generated, despite the fact that your salt cell is working overtime. Many salt systems will shut down, in a self-protection mode, when low water temps are felt. This of course, isn’t a major deal for spas and hot tubs — so long as you maintain the water 65° or higher, you’ll have no issues.
- Expensive. Whether we are talking standalone components or built-in systems, salt water chlorinators are expensive ($500 or more). Having said this, you are going to save money on spa chemicals, which offsets the initial cost to some extent.
- Saltwater Corrosion – Salt is corrosive to steel fixtures — a specific issue for salt water hot tubs when compared with swimming pools. This generally is not a problem if the system is used at appropriate levels, but in the actual world, things don’t always happen properly.
- The mobile has to be cleaned occasionally which is a bit of a messy job
