Keep your pool or spa water clean with Bestway’s range of Heater Pumps and Filter Cartridges. An integral part of any setup, they play a vital part in ensuring your pool or spa water remains comfortable and clear, allowing you to enjoy it at a moment’s notice. Some pumps now include the new Freeze Shield™ technology, allowing you to set the pump to run at a low temperature in a power saving mode for long periods of time. This uses minimal energy whilst ensuring that the water does not freeze (the pump must be powered at all times).
