One of the defining characteristics of the Victorian climate is the significant drop in temperature once the sun goes down. In November, we often enjoy beautiful, sunny days followed by single-digit overnight lows. For pool owners, this creates a frustrating cycle: your heat pump works effectively to warm the water during the day, only for that heat to escape into the cold night air. This phenomenon, known as evaporation, is responsible for most of the heat loss in swimming pools. To run an efficient and cost-effective heated pool in Victoria, you must address heat retention.
The Role of Pool Blankets
The most effective weapon against overnight heat loss is a high-quality pool blanket. Think of it as putting a lid on a saucepan; it traps the energy inside. At Sunlover, we often explain that installing a heater without a blanket is like running your home ducted heating with the windows open. A pool blanket acts as an insulating barrier, significantly reducing evaporation and locking in the warmth generated by your heat pump. By using a blanket overnight, you can wake up to a pool that has retained most of its temperature, meaning your heat pump has to do far less work the next day to get it back to swimming conditions.
Saving Water and Chemicals
Beyond temperature control, heat retention strategies offer broader environmental and financial benefits. Evaporation doesn’t just steal heat; it steals water and expensive chemicals. In a climate where water conservation is always a priority, a pool blanket can stop thousands of litres of water from evaporating over a single season. This means less time topping up the pool with the garden hose and less money spent rebalancing your salt or chlorine levels. It is a holistic solution that protects your pool’s health while amplifying the performance of your heating system.
A System That Works Together
To get the most out of your pool this November, you need to view your heating and retention as a single system. Pairing a sleek new inverter heat pump with the right cover is the key to efficiency. At Sunlover, we can assess your specific pool setup and recommend a tailored solution that keeps the heat in and the running costs down. Don’t let the Melbourne nights steal your daytime warmth; invest in a complete heating solution and enjoy a warmer pool every morning.
