The innovative design and cutting-edge technology of the Electro In-Line+ pool heater offers superior performance, accuracy and reliability.
All Elecro electric heaters feature our unique and proven coiled heating element technology whereby a turbulent vortex is created in the water flow. This delivers outstanding efficiency and extended life expectancy by preventing the build up of mineral deposits on the heating element.
The Elecro In-Line+ is an enhanced version of the tried and tested Elecro Evolution pool heater, offering all the proven benefits of the Evolution model with even greater accuracy using a digital control that features a ‘Priority Heating’ facility. This ensures the pool water temperature remains constant. When activated, the control system starts both the pool circulation pump and heating process if necessary.
Actual and required pool temperatures are displayed on a LCD screen. The heater is either wall or floor-mountable. The water inlet and outlet fittings can facilitate connection to either metric or imperial standard pipes. The inlet moulding has been designed to eliminate the risk of air locking.
