Inverter Swimming Pool Heat Pumps VS Non-Inverter Heat Pumps

When it comes to swimming pool heat pumps, one of the main considerations is whether to opt for an inverter or non-inverter heat pump model.

While both can do the job of keeping your pool warm year-round, inverter technology provides enhanced performance and efficiency advantages worth exploring.

Let’s break down the key differences between inverter and non-inverter heat pumps for swimming pools to help determine the best choice for your needs.

What is an Inverter Heat Pump?

An inverter heat pump contains an internal variable-speed compressor controlled by an inverter drive. This allows the compressor to adjust its speed and output based on the needs of your pool and its current temperature. The heat pump can run at partial or full capacity as needed.

Non-inverter heat pumps operate at either full speed or not at all. They do not have the inverter drive that allows the compressor to adjust speeds according to water temperature requirements.

Efficiency and Heating Control

By varying compressor speeds, inverter heat pumps maintain a more consistent supply of heated water while expending less energy. This allows near-constant temperature control for comfortable swimming.

Non-inverter models must run at full power even during mild temperature changes. They are less efficient and potentially overheat the water at times and are generally much less precise with temperature maintenance. 

Operating Costs

Due to their variable-speed design, inverter heat pumps are much more efficient for each kilowatt of electricity used than non-inverter models. This results in dramatically lower running costs year after year. However, non-inverter heat pumps do have a cheaper upfront cost. 

Energy Star ratings also favour inverter heat pumps for their eco-friendly performance. BWT’s Pearl range, for example, can maintain optimal pool temperatures while slashing cost off your ever-increasing energy bills.

Noise Levels

Perhaps surprisingly, inverter heat pumps operate significantly quieter than non-inverter alternatives. Their ability to fine-tune speeds means smooth, consistent operation without intrusive cycling of compressors.

BWT’s Pearl models offer whisper-quiet performance. Neighbours will appreciate the peace and quiet afforded by inverter tech.

Durability and Lifespan

With fewer internal components prone to wear and tear from frequent starting/stopping cycles, inverter heat pumps last substantially longer.

BWT goes one step further by backing the vital heat exchanger in their Pearl range with an unprecedented 25-year warranty for complete long-term protection of investment. Buyers can feel secure in their choice.

So Which Heat Pump Should You Opt For?

Given the empirical benefits of greater efficiency, convenience and lower running expenses, inverter heat pumps prove the smarter investment for pool heating. 

When coupled with many other features when purchasing from an industry-leading brand like BWT such as a 25-year inverter warranty, access to support and data from your smartphone and much more, Australian pool owners can relax knowing opting for an inverter gives total flexibility, savings and satisfaction for years to come.
