The Elecro Optima Compact Plus comes with corrosion resistant titanium heating elemts as standard, marking it highly roburt and durable.

The Optima Compact Plus is designed and manufacturered to the highest specifications at the Elecro facility in Hertfordshire, England.  Compact in design, robust and ultra reliable, this heater is made to last, providing you the perfect water temperature with easy to use controls.

All Elecro electric heaters feature our unique and proven coiled heating element technology, whereby a turbulent vortex is created in the water flow. This deliveres outstanding efficiency and extended life expectancy by preventing the buildup of mineral and debris deposits on the heating elements.


The Optima Compact Plus can be easily operated using the touch screen digital thermostat.  The inlet moulding has weir chambers which induce a vortexing action eliminating the risk of air locking and reducing encrustation build up on the heating elements; while the outlet moulding accommodates a flow switch with gold tipped reed, for ultimate reliability and safety.  Over heating is prevented by a thermal safety cut out which can be manually rest. 

The heater can be vertically wall mounted using the supplied bracket, or free standing.
