The unique design and robust construction of the Elecro G2 Heat Exchanger offers an unrivalled heat transfer surface area, making it one of the most efficient products on the market.
They feature a densely packed tubular bundle in a thermally insulated, uniquely designed polyamide-rubber tube, primary chamber. The relatively small volume of the chamber and large surface area of the internal tubing provides superb heat transfer efficiency and minimal energy loss, making the G2 the perfect choice for all applications including gas or oil fired boiler circuits, solar panels, heat pumps or chillers.
The G2 is designed and manufactured in Hertfordshire, England to the highest specification, using the strongest and most durable materials. The heat exchanger shell is constructed from BS 316L stainless steel (EN 1.4432) and enclosed by a rigid thermal casing for enhanced insulation of the primary (hot) water flow, ensuring greater heat transfer; this is capped at each end with primary and secondary moulded fittings manufactured from specially formulated polymer alloy material.
It has been designed to allow the installation engineer to select which way to plumb the primary and secondary water to achieve maximum thermal gain. This is achieved by routing the primary (hot) flow in an opposing direction to the secondary (pool) water.
The standard G2 heat exchanger is supplied complete with:

  • 2 x 1" male/male Brass primary connections
  • 1 x 1" Brass Non-return valve
  • 1 x Titanium thermostat pocket
  • 1 x Blanking cap & coin gasket (for non-thermostat side)


The Elecro G2 heat exchanger is installed in the pool filtration circuit from which water passes through the tube side of the exchanger. Water from the primary heating circuit flows counter current through the shell side of the exchanger, heating the swimming pool water.
