40mm plumbing unions. 
Minimum flow rate of 67 LPM 
Maximum flow rate of 266 LPM 
Ideal flow rate of 167 LPM 
592mm long

Installation of these heaters requires:
Weather protection, water splash protection (away from cartridge filters, etc)
Horizontal upright mounting only either on the floor or wall mounted on a shelf. 
Outlet pipe must plumb vertically UP before it can go downwards (so that the heater is not the highest point in the adjoining plumbing)
Chemical injection MUST be installed downstream only AND a non-return check valve MUST be fitted between the heater outlet and any chemical injection point.

Digital thermostat controlled with overheat protection and flow switch protection.
3 year return to base warranty.

The Titan Optima heater is manufactured from top quality components and material at the Elecro works in Hertfordshire, England.

Construction consists of three flow tubes which are fitted to the uniquely designed manifold mouldings made from specially formulated polymer alloy material. Spiral wound titanium heating elements provide a 'Vortex' water flow, these are positioned equidistantly along each flow tube, providing ultra efficient performance. The low Watts density of these elements guarantees extended life and reliability. The outlet manifold accommodates a flow switch which provides a digital signal to the control board. The inlet manifold is fitted with a titanium temperature detection pocket, fitted with NTC temperature sensor.

The heater control panel is on the top of the enclosure containing the indication and fault lights as well as the digital touch control screen. The unit can be floor or wall mounted and is supplied complete with a bracket for vertical wall mounting .


The Titan Optima heater can be easily operated using the touch screen control panel. The inlet manifold has been designed to minimise flow imbalance between the flow tubes, greatly reducing the risks of air locking. Safety and equipment protection is provided by the highly reliable flow switch, over temperature protection is provided by the four safety thermal cut outs (auto-reset) and a safety thermal cut out (manual reset).

The digital control board allows accurate control of the pool water temperature thanks to its high precision. The blue digital characters on the touch screen are clearly legible, even in bright sunlight.

To reduce voltage drop on start-up, the heater element banks are energised in a staged cascaded sequence, with a time delay between energising each bank.
