The Elecro G2 is the perfect choice for all applications including gas or oil fired boiler circuits, solar panels, heat pumps or chillers. The G2 is manufactured to the highest specification, using the strongest and most durable materials.
The shell is constructed from BS 316L stainless steel (EN 1.4432) and enclosed by a rigid thermal casing for enhanced insulation of the primary water flow, ensuring maximum efficiency.
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 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” non-return valve
• Titanium thermostat pocket
Fully equipped upgrade kits are available with the G2 model and offer either analogue or digital thermostat controls for temperature accuracy and display. These are easy to fit or retro-fit and are supplied complete with:
Digital Kit
• Digital control thermostat 0~45°C (0.5˚C differential)
• Grundfos booster pump • Flow switch
• 1” female/female brass fitting
• NTC temperature sensor
Analogue Kit
• Analogue control thermostat: 0~40°C (1˚C differential)
•Grundfos booster pump
• Flow switch
• 1” female/female brass fitting

ΔT = Temperature difference between Primary (HOT) and Secondary (POOL)
To calculate BTU multiply kW x 3412
kW x 3412 = BTU Output
