Product background
Compost, mix and evaporate within the toilet
The EcoLet™ 240 Automatic 25a is a self-contained toilet that receives both urine and solids into the same composting process.
Internal heating supports moisture evaporation, while the automatic mixer turns the composting material after use to support aeration and decomposition.
The system is designed as a zero-leachate toilet, with liquid managed through the heated composting and evaporation process rather than through a separate routine blackwater discharge.

Automatic compost management after use
Step 1 CollectUrine and solids enter the self-contained composting chamber together.

Purchase context
What to plan for with the 25a
The 25a is a powered composting toilet. Correct ventilation, electrical supply and operating settings form part of the complete installation.
The system uses automatic mixing and internal heating, so it should be selected where the available power supply and expected use suit this operating pathway.
Good to know before purchase

Nature Quick microbes referenced in some overseas EcoLet™ material are not available in New Zealand.
