Frequently asked questions
1. What is an inverter pool heater, and is it suitable for inground pools?
An inverter pool heater is a high-efficiency pool heating system that uses variable-speed technology to adjust its power output based on the pool’s temperature needs. It consumes far less energy than traditional heaters, maintains a consistent water temperature, and operates more quietly.
Inverter pool heaters are the ideal choice for inground pools. They efficiently heat larger water volumes, maintain stable temperatures, and work well in various climates, making them perfect for year-round inground pool use.
2. What are the differences between the Flow Pro 48 and 58, and the Flow Max 80 and 107?
The primary differences between these models are their heating capacity (BTU) and the pool size they are designed for.
Flow Pro series: Designed for small to medium-sized pools
Flow Max series: Designed for larger pools and higher heating demand
Higher model numbers = higher BTU output and faster heating performance
Choosing a higher-capacity model ensures faster heating and more stable temperature control, especially in cooler climates or for larger pools. You can refer to this machine comparison.
3. Is the inground pool heater quiet during operation?
Yes. The Blueplenum pool heater operates at approximately 52 dB at 33 feet, which is considered very quiet for pool heating equipment.
