Incinerating toilets burn waste to a small amount of ash using electricity or gas. They suit cold sites, permafrost or places with no soil for treatment, but need a reliable energy supply.
How
- Get the manufacturer's technical data for energy use per cycle, venting, clearances and daily capacity, then check it against your power or gas budget.
- Plan a dedicated flue or vent exactly as the manufacturer and your building code require.
- Ask your authority whether the model is approved and whether a certification such as NSF/ANSI 41 is required where you live.
- Plan for greywater separately, as incinerating toilets only take toilet waste.
- Budget for servicing and spare parts, as these are mechanical and heating appliances.
Safety: Hot surfaces, flue gases and fire risk. Follow the manufacturer's clearances and fit a carbon monoxide alarm if gas-fired (see the safety module).
