The robust and durable construction of the Elecro Flow Line provides efficient, safe and reliable performance.
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 Flow Line pool heater is designed and manufactured to the highest specification to effortlessly heat your pool to the desired temperature.
Construction consists of a flow tube which is fitted with Inlet and Outlet mouldings manufactured from specially formulated polymer alloy material.
The outlet moulding accommodates a reversible flow switch with a gold tipped reed, and Titanium fulcrum pin.
The heater is supported on two swivel feet; these can be rotated to permit either wall or floor mounting. The heater control components are positioned on the top face of the casing.
The inlet moulding has been designed to ensure full immersion of the elements, greatly reducing the risks of air locking.
The Flow Line model is non-wired and must be connected to an external contactor to switch the power to and from the heating elements.
For fully Pre-Wired options please see our Evolution or Optima Compact ranges.
