Pool Heaters: How to Choose the Right One for Your Pool

Ultimate Guide to Pool Heaters: Choose the Right Solution for Your Pool

A pool heater is an excellent investment, allowing you to extend your swimming season and enjoy precise temperature control for a comfortable swimming experience. This guide covers pool heater basics, various heating technologies, and essential considerations to help you choose the best pool heater for your needs.

Understanding Pool Heaters

How Do Pool Heaters Work?
Pool heaters warm your pool water by transferring heat through a heat exchanger. As water passes through the exchanger, it absorbs heat from the heater’s energy source—whether gas, electricity, or a hybrid system.

Are Pool Heaters Costly to Operate?
While adding a pool heater is a significant investment, its operational costs depend on energy efficiency. Higher efficiency means lower energy costs. For instance, a heater with 96% efficiency (like the Pentair ETi® 400) converts $0.96 of every $1.00 of gas into heat for your pool. Choosing an efficient heater saves money in the long run.

Key Factors to Consider When Choosing a Pool Heater

1. Heater Size
   Pool heaters are rated by their heating capacity in British Thermal Units (BTUs). Gas heaters typically deliver 175,000–400,000 BTUs, while heat pumps range from 100,000–150,000 BTUs. Your pool size and heating needs determine the optimal BTU rating.
2. Climate and Energy Costs
• Mild to Warm Climates: Heat pumps perform best where electricity costs are moderate.
• Cooler Climates: Gas heaters are ideal in areas with affordable natural gas or propane.
3. Pool Features
   Unique pool features like spas or waterfalls may influence your heating requirements. Consult a pool professional to ensure you choose the right solution.

Maximizing Pool Heater Efficiency

• Maintain Water Chemistry: Improper pool chemistry can damage your heater. Weekly testing is crucial to ensure proper pH and chemical balance.
• Winterize Equipment: If you experience seasonal weather changes, schedule a professional winterization service to protect your heater from freezing conditions.
• Use Pool Automation: Automating your pool system allows you to schedule heater run times, ensuring energy-efficient operation and cost savings.
