With rising energy costs, maintaining water temperature in your heated koi ponds or swimming pools through the colder months can be expensive. Euro-Matic’s Pool Insulation Balls offer a proven, cost-effective solution — ideal for reducing heat loss, evaporation, and keeping your fish healthy and active all year round. These covers are low-maintenance, reusable season after season, and eliminate the need for bulky winter structures or costly heating systems, offering an eco-friendly alternative that works with nature instead of against it.
Our insulation balls are made from durable, UV-stabilised plastic and float on the surface of your pond or pool to create a self-forming, flexible thermal cover. By covering over 91% of the water surface, they dramatically reduce heat loss, lower evaporation, and prevent ice formation — all while allowing light and oxygen exchange to keep the water healthy. Their translucent design ensures natural light reaches the water, promoting a more balanced aquatic environment for fish and plants while also maintaining visibility and ease of access.
Cold water below 4°C can be fatal for koi carp. Fortunately, Euro-Matic’s translucent pond balls let sunlight through, keeping the environment well-lit and warm.
This helps koi stay active, feed normally, and grow during winter. As a result, it prevents dormancy and reduces illness risk.
Even insulated pools can lose 70% of heat from the open surface. But with our pool insulation balls, that heat loss drops by up to 75%. Evaporation is also reduced by up to 90%, saving energy and money.
For instance, a 6m x 10m pool heated to 25°C can lose 30,000 BTUs per hour without cover. Our insulation balls help prevent that loss effectively.

Customer Feedback
“My fish are now more active and feeding as the water temperature is stabilising around 13°C. This means they will feed and therefore grow and will be saved from viral infections.”
