How to Choose the Right Chlorinator for Your Pool

How to Choose the Right Chlorinator for Your Pool

Choose a durable, 3-5 year lifespan chlorinator, compatible with your pool's flow rate, and with a 2-3 year warranty for salt or chlorine systems, ensuring efficiency and low maintenance.


When choosing a chlorinator, the capacity of the device is one of the primary factors that needs to be reasonably evaluated. Establishing a match between the pool size and the capacity output of the chlorinator in question is a necessary step towards guaranteeing good water sanitation.

  • The necessity of a powerful chlorinating system

Calculating your pool’s volume in litres or gallons

The first step is establishing the size of your swimming pool in terms of volume. The volume of the pool can be determined by multiplying its length by its width and then the result by the average depth. For example, with a rectangular swimming pool measuring 20 feet by 10 feet and with an average depth of 5 feet, the volume will calculate to be 20 * 10 * 5 = 1000 cubic feet. Since 1 cubic foot is approximately 7.48 gallons; given the average depth of the sample pool which is 5 feet, the pool volume will be 7.48 * 1000 = 7487 gallons or 28,317 litres.

Chlorinators: Size vs. Pool size compatibility

After measuring the approximated size volume of the pool, a capacity output which is equal to or exceeds the pool’s volume should be chosen. Most are capable of adjusting their output relative to the desired minimum levels either per hour or per day. In the example in which the pool approximated volumes for chlorine coverage were 10,000 gallons, a one-pound capacity chlorinator per day should be selected.

The necessity of a powerful chlorinating system

Having a strong chlorinating system is a desirable condition for any swimming pool owner. The capacity output is directly proportional to the amount of pool size or volume that gets covered, meaning that any device that lacks sufficient capacity will not amount to dependable water sanitation.

Choosing Durable and Low-Maintenance Chlorinator

When it comes to purchasing a chlorinator, its durability with low maintenance is essential. A high-quality and durable chlorinator, manufactured from a corrosion-resistant material, will serve you well for many years. Besides, it should feature a long cell lifespan and as much warranty as possible.

Why cell longevity and warranty coverage are important

The cell of your chlorinator is where the actual chlorination occurs. The lifespan of the cell should be no less than 3-5 years. Thus, when we talk about a durable product, we mean that it should withstand a significant period and require changing as infrequently as possible. Moreover, a warranty should be included for a chlorinator model that is up to 2-3 years of usage.

Self-cleaning chlorinator models: comparing different models

In contrast, you should focus on self-cleaning models for your swimming pool. Yes, they can be slightly more expensive than manually cleaned chlorinators, but they are easier to maintain. You will not have to scrape the plates now and then to avoid scale buildup. However, some models are better than others depending on the frequency of self-cleaning and whether this feature has any effect on overall performance.

Estimating the long term and maintenance chlorinator costs

People tend to choose cheaper chlorinators when it comes to home appliances. However, inexpensive chlorinators will inevitably lead to higher maintenance and fabrication costs in the long run. Yes, high-quality models are more expensive, but considering their durability and reliability, low maintenance, and changing costs that might occur in the next 20 years.

Ensuring that the chlorinator is compatible with my pool system

Lastly, check if the chlorinator is suitable for your pool system. This concerns the plumbing connections, the necessary amount of electricity, and whether a chlorinator can work in conjunction with the pool filtration system. To keep your product running, refer to the manual or a pool business representative.


The type of pool water, the material you used in the pool, and equipment you have can influence the type of chlorinator you should choose. For example, if you have a saltwater pool, using a salt chlorinator makes more sense since it doesn’t require additional chlorine addition as freshwater pools would need. Another feature to consider is the material and equipment. If you chose using aggressive chloride such as NaCl, better use a chlorinator that is not affected by it and goes well with all the other materials you used.

Experts and the local pool supply store

Even after providing answers to the questions, deciding on the chlorinator to use and managing the chlorinator for some time demanding. Most stuff you do with your chlorinator may sound simple for pool experts, cost, and drain you a lot. In case of doubt, don’t hesitate to ask the local pool supply store and explain the problem or pool conditions to them. It can provide you personalized assistance since they know more about the pool, equipment, materials you use.

Second alternative for chlorination: salt system

The alternative to regular chlorinations has been the use of a high-salt level that takes away the need to add extra chlorine. Many pool owners have been using this variation for a long time, and you can still check it. Even though a pool still uses chlorine, its taste and the feel are different. The main difference is that with a salt system, the chlorine is manufactured consistently by you so that it never runs out. The only level you can trust and control the amount of chlorine reacts in your pool is the salt chlorination system.


In conclusion, salt chlorinators are costly in the first place, and they help you save money in the long run. This is because you won’t be buying the expensive bottles of chlorine frequently, and you won’t burn gallons of gas mixing your hypochlorite every week. The only task you will be handling is salt, so you have to keep adding and balancing it. However, salt system cells need constant cleaning.

Overall, for cleaner, cheaper, and skin-friendly pools, having these alternatives is suitable. According to the financial capability, size of the pool, uses, and the accessibility to your pool, it’s your time to decide if you will adopt any of these alternatives. However, keep in mind if you have a big pool or a lot of bather pools that you can afford paying many dollars for chlorine, then the choice is different.

Considerations Regarding Installation and Professional Support

A professional installer can help you with the installation and provide you with advice on whether you need an additional inspection. Furthermore, keeping in touch with professionals and asking for their help could be invaluable. If you face any problems with the salt chlorinator, the experts who installed it could provide you with technical support. Some professionals also offer maintenance services for the salt chlorinator, which may ensure that your system operates optimally.

Role of Expert Advice Regarding Chlorinator Selection

Having the right equipment to provide you with expert advice on salt chlorinator selection is beneficial. Specialists can guide you through the process, explain technical data, and answer all your questions. Moreover, using expert advice helps you ensure that you will not regret your purchase because it was not suitable for your needs.

Installation Options: In-Line Versus Off-Line Chlorinators

In-line chlorinators are connected directly to the plumbing that connects to your pool and is run in parallel. Off-line chlorinators are independent devices, and you need to mix the feed with water before transferring it to the system. In terms of each option’s pros and cons, it would depend on your personal experience and knowledge, as well as the specific circumstances. Thus, your choice should be guided by the specific configuration of your pool.

Technical Support and Maintenance Services

Technical support and the ability to maintain the salt chlorinator are crucial. Experts can also help with the installation, should you choose to do it yourself. Various manufacturers and pool supply companies offer valuable technical assistance and maintenance services.

Long-Term Benefits and Cost-Effectiveness

When considering the investment and comparing it to potential savings over the long run, it is essential to realize how cost-effective the system is. High-end salt chlorinators can be expensive to install, but they are ultimately designed to save you money on chlorine and reduce maintenance costs.

Advantages of Switchable Installation Methods

This alternative allows you to switch between two systems – for instance, regular chlorine and ozone or salt and mineral purification. A competent professional can help you make the right choice and combine two compatible methods for improved performance on that system.

Reliable performance guaranteeing peace of mind
It is essential that any chlorinator is able to provide a safe and healthy environment for the pool. By choosing the right system and properly caring for the equipment associated with keeping the pool water clean, one will be able to maintain their pool without worry and enjoy a refreshing swimming experience.
