Indoor Pool Solutions

Indoor pools offer year-round swimming in a controlled environment, shielded from weather, UV exposure, and outdoor debris. They’re ideal for fitness, therapy, and leisure—especially in colder climates or urban settings where outdoor space is limited.

Advantages:

• 🌡️ Climate control allows consistent water temperature and comfort.
• 🧼 Easier to maintain cleanliness and water chemistry.
• 🕒 Extended usability—day or night, rain or shine.
• 🧘‍♀️ Enhanced privacy and noise reduction.

Disadvantages:

• 💧 High humidity levels can lead to condensation, mold, and structural damage if not properly managed.
• 🌬️ Ventilation systems must be carefully designed to remove chloramine-laden air and maintain air quality.
• 💸 Higher upfront and operational costs due to HVAC, dehumidification, and insulation requirements.
• 🛠️ Maintenance complexity increases with enclosed environments.

Proper ventilation and humidity control are critical—not just for swimmer comfort, but to protect the building envelope and indoor air quality. Systems like energy recovery ventilators (ERVs), dehumidifiers, and corrosion-resistant ductwork are often essential.

Indoor pools are a versatile solution for a wide range of users, offering controlled environments that support safety, comfort, and year-round access.

Ideal for:

• 🏢 Commercial Facilities: Hotels, resorts, and wellness centers use indoor pools to elevate guest experience and extend seasonal offerings.
• 🏫 Swim Schools & Aquatic Training: Consistent water temperature and weather-proof scheduling make them perfect for lessons, rehabilitation, and competitive training.
• 🏠 Domestic Installations: Homeowners seeking privacy, convenience, and lifestyle enhancement enjoy indoor pools as a personal retreat or fitness hub.
• 🏥 Therapy & Rehab Centers: Warm-water therapy pools support recovery, mobility, and pain management in a controlled setting.
• 🏛️ Community & Council Pools: Indoor designs allow for inclusive programming, from toddler splash zones to senior aqua aerobics, regardless of climate.

Whether for leisure, learning, or legacy, indoor pools offer unmatched flexibility—but require thoughtful planning around ventilation, humidity control, and long-term maintenance.

The first thing you need to understand is that the heat off the pool is in the form of warm moisture-laden air (evaporation), and is the single biggest heat loss from a pool. This will heat the pool room area as well as directly increase the humidity levels of the indoor space.

Humidity and heat can cause a very uncomfortable sweat-box feeling for non-swimmers. It can also produce moisture build up on windows, walls, ceilings and cause on-going damage of rusting, mildew and rotting to occur.

Air Conditioning & Space Air Heating

To counter the heat and humidity issues the purchase of air-conditioning systems are considered. By providing heat to the pool room close to the pool temperature provides the best results.

Space Heating

Space heating systems are usually gas or electric-based systems. These days they also use a process known as preheating air. Used to remove any humidity from outside air prior to pushing the warm air into the space. This can be a very effective but expensive method.

Ventilation

Unlike Air-conditioning ventilation is a critical requirement of indoor pools, not just for fresh air, it also helps to passively reduce chlorimides, heat and humidity.

Australian Standards state that indoor pools require a certain degree of fresh air and ventilation. please see your state regulations as it varies state to state.

Ventilation can come from either passive or active forms.

• Passive: Windows and doors, vents and whirly Birds
• Active:   Air Fans, Ventilation systems and Extraction fans.

Although ventilation is crucial to good pool room heath, there is a trade-off between standards requirements, people’s creature comfort and what is affordable.

As you increase ventilation levels to improve comfort for swimmers & non-swimmers, you also increase evaporation levels of the pool which directly increases the heat energy demand on the pool.

Dehumidification

Even though air-conditioning and ventilation go a long way to remove heat and humidity form the pool environment, they are often not effective enough at removing latent moisture in the air and the use of a dehumidifier is engaged.

These work by drawing air through an evaporator – condenser circuit system. The act of evaporation and condensing causes moisture to come out of the air in the form of condensate.

Toyesi has spent much research in developing a system to battle these indoor pool issues, but at the same time help reduce running costs, and significantly reduce wasted energy losses, yet provide a system with significantly lower capital equipment costs than buying a multitude of equipment to achieve the same results.

When you consider these capital costs.

• Pool heater $5000 to $20,000 +
• Air-conditioner $5000 to $20,000 +
• Ventilation $1000 to $10,000 +
• Dehumidifier $5000 to $20,000 +

Using the coupling of a heat pump with dehumidification technology, we can draw air from the pool room, remove some of the latent moisture from the air, and create significant airflow by venting back the cooler drier air.

At the same time, we capture the heat load that was lost from the pool utilising our heat pump technology and apply it directly back into the pool where it belongs. This process also increases our heat pump efficiencies, which also adds to reducing overall running costs.

Utilising our efficient PCVER system to do the work of a pool heater, as well as for ventilation, dehumidification, energy recovery and pool room temperature manager, we can significantly reduce the overall capital equipment outlay. Also, overall running costs will be much lower due to only having to run one efficient system.
