How To Heat A Pool: Technologies Compared

Heating your pool offers more than just a warm swim. By maintaining a consistent pool temperature, you can enjoy your pool for more months each year, benefit from the fitness and therapeutic uses, and create a relaxing and inviting environment all year round. 

There are various options for heating your pool, each with different levels of energy efficiency and cost.

While it might seem like an expensive endeavour, installing a pool heater is essential in most Australian climates – some say even more important in Tasmania, if you want to maximise your pool's use.

We’re going to take a look at the top pool heating technologies and explore the pros and cons of each to help you make an informed decision.

1. Solar Pool Heating

 How It Works: Solar pool heating systems use solar collectors, typically installed on your roof, to harness the sun’s energy. Water is pumped through these collectors, heated by the sun, and then circulated back into your pool.

 

Pros:

●       Free Energy: Utilises solar energy, resulting in minimal running costs.

●       Environmentally Friendly: Reduces your carbon footprint using renewable energy.

●       Long Lifespan: Solar systems are durable and require little maintenance.

Cons:

●       Weather Dependent: Efficiency drops on cloudy days and during the night.

●       Slower Heating: It can take longer to heat the pool compared to other methods.

●       Initial Cost: Higher installation cost due to solar matting and setup.

 

Solar heating is perfect for those who live in sunny areas and want an eco-friendly, cost-effective solution. However, it might not be the best choice if you need reliable heating on demand.

2. Heat Pumps

How It Works: Heat pumps draw in warm air from the environment, which is then used to heat the pool water. They work similarly to reverse-cycle air conditioners.

 

Pros:

●       Energy Efficient: For every unit of electricity, heat pumps can generate several units of heat.

●       Year-Round Use: Can heat the pool even in cooler weather.

 

Cons:

●       Higher Initial Cost: More expensive to purchase and install than gas heaters.

●       Relies on Air Temperature: Less effective in very cold weather.

Ongoing Costs: Though more efficient than gas heaters, they still incur electricity costs.

3. Electric Heaters

How It Works: Electric pool heaters use electric resistance elements to heat the water directly, similar to how a kettle heats water.

Pros:

●       Simple to Install: Easier and cheaper to install than other systems.

●       Ideal for Small Pools: Effective for heating smaller pools and spas.

Cons:

●       High Operating Costs: Electric heaters are less energy-efficient and more costly to run.

●       Less Eco-Friendly: Higher electricity consumption can be less sustainable.

●       Slower Heating: Takes longer to heat the pool compared to gas heaters.

 

Electric heaters are best suited for small pools or spas where other heating systems may not be practical. They are

are easy to install but come with higher operational costs.

Key Takeaway for Tasmanians

For Tasmanians, where sustainability and efficiency are key considerations, heat pumps particularly when coupled with solar are the best options.

 

Both systems offer environmentally friendly heating solutions, with solar heating being virtually free to run once installed and heat pumps providing efficient heating even in cooler weather.

 

Don’t Forget Pool Covers: Regardless of the heating system you choose, using a pool cover is essential. Pool covers help retain heat, reduce evaporation, and minimise heating costs. Keeping your pool covered when not in use can significantly improve the efficiency of your heating system.
