All connections are plug and play, so no electrician is required. The Aestiva Pump station housing are UV stabilized for outdoor use.

The Aestiva controller and the Grundfos pump are widely used in OEM supplied solar hot water heater brands such as Solargain, Neopower, Aussiewide, Leda, SolarEast and Solarpower. 

The fitment of the Aestiva controller also makes it a direct swap and replacement for Senztek and Resol controllers used by Apricus, Edson and Others. 

The pump station assembly make it ideal to swap any solar systems, such as Rheem Lo-line, Rinnai, Aquamax and Chromagen. Technical support available, just give us a ring or message.

Pump solar kits include: 

Pump unions (Pump's 25mm BSP thread to half inch male thread) 

+ Solar rated non return valve solar rated for both Flat plate and Evacuated tube applications

+ 15MI Hex Nipple

+ 15FI x 15C Hex Union

+ 15MI x 15C Hex Union

+ flow meter/regulator with inbuilt ball valve 

(the flow meter allows 5L/min plus of flow. However, the gauge only reads up to 3L/min. When the pump is operating at a higher flow, the flow meter is not restricting the flow, but just not readable above 3. Most manufacturers recommend flow setting at 1-2L/min for the best system stratification and in compliance with Clean Energy Regulator CER STC rules

Notes

When compared to Resol and Senztek controllers, the Aestiva controller is newer and feature more technology. The end user is not limited to just 1 tank sensor, but can add additoinal ones if required. The Resol unit is not sealed and not weather proof, meaning it is prone to water ingress and insects infestation. Senztek controller has no SHM mode to address the overheating/stagnation problems.
