Specialist Pool Heating & Climate Control in Southampton, Hampshire. We design and install high-performance heating and environmental control systems for residential and commercial pools.
At HydroTech Pools, we design and install bespoke heating and environmental control systems for indoor and outdoor swimming pools. From air source heat pumps and gas boilers to full air handling units (AHUs) and heat recovery systems, our solutions are engineered for efficiency, comfort, and long-term reliability.
Every project begins with a detailed assessment of the pool environment — considering pool size, usage, construction type, and existing infrastructure — to determine the most suitable system.
Where a full AHU integration is possible, we deliver fully coordinated installations. Where this isn’t feasible, we apply the same principles through targeted retrofit options such as standalone dehumidifiers, smart ventilation enhancements, or integrated heat recovery systems. Our goal is to create the ideal swimming environment using the best-fit approach for your space, budget, and performance needs.
Air source heat pumps are a highly efficient solution for heating both indoor and outdoor swimming pools. At HydroTech Pools, we design and install systems that extract ambient heat from the air, significantly reducing energy consumption compared to traditional heating methods. With correct sizing, placement, and integration into your plant room setup, air source heat pumps provide reliable water heating with low running costs — ideal for clients seeking sustainable, future-ready solutions.
At HydroTech Pools, we install all air source heat pumps on purpose-built rubber-mounted feet to reduce vibration and ensure long-term stability. We also fully insulate all external pipework with weather-resistant lagging to minimise heat loss and protect against freezing. Each system is supplied with a bypass valve arrangement as standard, allowing for flow control, seasonal shutdowns, or future servicing without disrupting the rest of the pool plant. These installation details reflect our commitment to professional standards and ensure your heat pump operates efficiently from day one.
Gas boilers remain a robust choice for pool heating where rapid heat-up times or high thermal loads are required. Whether used as a primary heat source or as part of a hybrid system, our installations are specified to suit the demands of each project. We ensure correct sizing, safe flue routing, and integration with modern control systems — delivering efficient operation without compromising compliance or ease of maintenance.
Every gas boiler we install is specified to meet the heating demands of your pool, with a focus on long-term reliability and safe operation. At HydroTech Pools, we ensure each boiler is securely installed with appropriate flueing, adequate ventilation, and compliant gas connections — all in line with current regulations. We consider access for servicing, system efficiency, and future upgrade potential as part of every install. Whether you’re replacing an outdated unit or integrating a boiler into a hybrid heating system, our approach prioritises performance, safety, and ease of maintenance.
Dehumidifiers are essential for maintaining healthy humidity levels in indoor swimming pool environments. Left unchecked, high moisture levels can lead to condensation, mould, and long-term structural issues. At HydroTech Pools, we install high-performance dehumidifier units that are designed specifically for pool hall conditions, helping to protect your building fabric and create a more comfortable atmosphere.
In addition to extracting moisture from the air, many dehumidifiers can also support space heating functions. We offer units that are equipped with either low-pressure hot water (LPHW) coils — allowing them to receive heat from a central boiler system — or integrated electric heating elements for simpler standalone operation. Whether heating is needed as a primary or supplementary source, we specify systems that suit your project’s infrastructure and energy requirements, ensuring seamless integration with the rest of your plant equipment.
Our dehumidifier installations are tailored to the layout and construction of the pool space. Units can be either wall or floor mounted directly within the pool hall, or installed externally on an adjacent wall using a through-the-wall grille system. This setup allows airflow to pass efficiently between rooms without relying on extended ductwork, which these systems are not designed to support.
We ensure every unit is positioned for effective moisture control, with cleanly managed condensate drainage and connections that are secure, durable, and built for continuous use. The result is a discreet, quiet-running system that keeps your pool environment stable, efficient, and protected year-round.
We design and install bespoke air handling units (AHUs) tailored specifically for indoor swimming pools. These systems combine ventilation, heating, humidity control, and heat recovery in a single integrated solution, maintaining comfort while preserving building integrity. Traditionally, AHUs are powered by low-pressure hot water (LPHW) from gas or oil boilers, but at HydroTech Pools, we also offer systems that integrate with air source heat pumps — providing a more sustainable, energy-efficient approach to pool hall climate control. Each AHU is specified to suit the volume and usage of the space, and coordinated with your mechanical systems for reliable, long-term performance.
HydroTech Pools approaches every AHU installation with attention to airflow, energy source, and long-term serviceability. We determine the optimal unit size and positioning based on your building layout, acoustic requirements, and system integration needs. All ductwork is carefully planned to suit the site, whether overhead or underfloor, ensuring effective air distribution throughout the pool hall. We align each unit with either an LPHW or heat pump-fed heating circuit and ensure access for maintenance, safe condensate drainage, and compliance with ventilation standards. The result is a clean, efficient installation that supports comfort and performance all year round.
Well-designed ductwork is essential for delivering effective climate control in indoor swimming pool spaces. At HydroTech Pools, we design and install ducting systems that distribute conditioned air evenly throughout the pool hall, helping to prevent condensation on windows and cold surfaces while maintaining consistent temperatures and humidity levels. We offer both overhead and underfloor ducting layouts, tailored to the building structure, aesthetics, and ventilation strategy. Every system is specified to complement the connected air handling unit and maximise airflow efficiency with minimal noise or resistance.
Our ducting installations are carefully planned to suit the architectural layout and technical demands of each project. We select materials and routes that ensure durability, performance, and ease of access — whether routing through ceiling voids, service trenches, or exposed architectural features. All terminations are positioned to achieve balanced air distribution across the space, and our systems are sealed, supported, and commissioned in line with best practice. The result is a quiet, efficient airflow solution that integrates cleanly with your overall pool climate control system.
Heat recovery ventilation (HRV) systems are a smart way to reduce energy loss in indoor pool environments. These systems extract warm, moisture-laden air from the pool hall and use it to preheat incoming fresh air — significantly improving overall efficiency and reducing the demand on your primary heating source. At HydroTech Pools, we specify HRV units that suit both residential and commercial pool halls, helping to stabilise internal conditions while lowering operating costs. Whether installed as part of a complete air handling setup or used as a standalone ventilation enhancement, HRV systems contribute to a more sustainable and cost-effective pool environment.
Our HRV installations are designed around your pool hall layout, usage patterns, and existing ventilation strategy. We assess airflow paths and mounting positions to ensure optimal heat exchange performance, while maintaining clear access for servicing and filter changes. Systems are connected with precision to both intake and extract ducts, and balanced to prevent drafts or pressure imbalances. Where appropriate, we integrate HRVs with other climate control systems — ensuring they function as part of a unified, efficient solution for maintaining comfort and reducing waste.
