Lex Pools: Trusted by Over 50 Swimming Schools

For schools, colleges, aquatic centres and learn-to-swim facilities, maintaining the correct swimming pool temperature isn’t simply about comfort—it directly impacts training schedules, swimming lessons, competitions and facility utilisation throughout the year.

Choosing the right commercial pool heating system is therefore one of the most important investments a school can make.

Lex Pools has specialised in commercial swimming pool heating systems since 1998 and has become one of Gauteng’s most experienced installers of commercial heat pump and solar heating solutions.

Today, more than 50 swimming schools across Gauteng trust Lex Pools to design, install and support reliable, energy-efficient pool heating systems that keep their facilities operating year-round.

Why Schools Invest in Commercial Pool Heating

Unlike residential swimming pools, school and training pools experience continuous daily use and require consistent water temperatures for swimming lessons, squad training and competitive events.

Without an efficient heating system, colder winter temperatures can reduce pool usage, interrupt swimming programmes and create an uncomfortable environment for learners.

A professionally designed commercial pool heating system allows schools to:

• Maintain comfortable swimming temperatures throughout the year
• Extend the swimming season
• Support learn-to-swim programmes during winter
• Improve comfort for students and coaches
• Reduce operating costs through energy-efficient technology
• Maximise the value of existing aquatic facilities

For many schools, reliable pool heating has become an essential part of their sports and aquatics programme.

Commercial Pool Heating Solutions

Commercial Inverter Heat Pumps

Modern inverter heat pump technology offers one of the most energy-efficient ways to heat large commercial swimming pools.

Unlike older fixed-speed systems, inverter heat pumps automatically adjust compressor speed according to heating demand. This reduces electricity consumption, improves temperature stability and significantly lowers operating costs over time.

Benefits include:

• Exceptional energy efficiency
• Reduced running costs
• Quiet operation
• Intelligent temperature control
• Reliable year-round performance
• Remote monitoring capabilities on selected systems

Commercial Solar Pool Heating

For facilities with sufficient roof space, commercial solar pool heating provides an environmentally friendly way to reduce heating costs while extending the swimming season.

Lex Pools designs and installs commercial solar heating systems for schools, sports facilities and resorts throughout South Africa.

Heating is only one part of an efficient commercial swimming pool.

Lex Pools also supplies, installs and services:

Project Spotlight: Jeppe High School for Boys

Lex Pools recently completed a major heating upgrade at Jeppe High School for Boys, replacing outdated fixed-speed heating equipment with four new 65 kW commercial inverter heat pumps.

The new system delivers:

• Improved energy efficiency
• Significantly quieter operation
• Reliable year-round pool heating
• Lower long-term operating costs
• Modern inverter technology designed for continuous commercial use

The project demonstrates how upgrading ageing heating infrastructure can dramatically improve both performance and operating efficiency.

Project Spotlight: St Benedict’s College

For St Benedict’s College, Lex Pools designed and installed a high-capacity commercial heating system comprising six 65 kW commercial inverter heat pumps.

To maximise system performance, our installation included:

• Purpose-built reinforced concrete equipment plinths
• Balanced 160 mm commercial pipework
• Hydraulic flow balancing to ensure equal water distribution across every heat pump
• Secure Clearview fencing around the plant area
• Professional commissioning and optimisation

Correct hydraulic balancing is critical in commercial installations and ensures every heat pump operates at maximum efficiency while extending equipment lifespan.

Project Spotlight: Curro Rivonia High School

Lex Pools installed four 65 kW commercial inverter heat pumps at Curro Rivonia High School to provide dependable swimming pool heating throughout the year.

One of the standout features of this installation is the integrated Data Terminal Unit (DTU), allowing authorised staff to remotely monitor and manage the heating system via the internet.

Using a smartphone or computer, facility managers can:

• Check current pool temperatures
• Adjust target water temperatures
• Configure heating schedules
• Monitor system performance remotely

This level of control helps schools improve energy management while reducing unnecessary operating costs.

Frequently Asked Questions

What is the best heating system for a school swimming pool?

For most schools, commercial inverter heat pumps provide the best combination of energy efficiency, reliable performance and long-term operating cost savings. Solar heating can also be an excellent solution where suitable roof space is available.

How warm should a school swimming pool be?

The ideal temperature depends on how the pool is used. Learn-to-swim programmes generally require warmer water than competitive training pools. Lex Pools designs each heating system around the facility’s operational requirements.

Can an older commercial pool heating system be upgraded?

Yes. Many schools replace ageing fixed-speed heat pumps with modern inverter systems, significantly improving efficiency, reducing electricity consumption and lowering maintenance costs.

Does Lex Pools provide maintenance and servicing?

Yes. We offer ongoing maintenance, servicing, system upgrades and after-sales support for commercial swimming pool heating systems, pumps, filtration and water treatment equipment.
