All Cinderella toilet models are constructed from highly durable parts. A correctly installed toilet with regular maintenance the toilet has a life span of 10+ years. Cinderella Incineration toilets are covered for defects in materials or workmanship for the period of three years from the original date of purchase for domestic use and a 1 year warranty for commercial or semi commercial use. ECOASH holds readily available replacement parts in New Zealand.

The Cinderella toilets are a hygienic toileting system that reduces faeces, urine and cotton sanitary products to an inert ash. The ash chamber heats up to 550 - 600 degrees Celsius killing all bacteria and viruses. There is no risk of coming into contact with live components. The waste material is incinerated after every use. The toilet exterior, seat and hatch are easily cleaned with general cleaning products.

This clause relates to sanitary fixtures and sanitary appliances using water-borne waste disposal. The Cinderella toilet is a waterless toilet. Our toilets are a hygienic alternative to conventional toilets. Please refer to the above paragraph under Building Code Clause G1.

Requires the safe use and distribution of electricity. The electric powered Comfort toilet is supplied with a NZ approved 10 amp, 250 V AC, 2 Pole 3 Wire Grounding Type I plug with a 2.5m cable length. The toilet can be plugged into an existing approved 220 – 240V AC 10amp household plug. If there is no power point available, one should be installed by a certified Electrician.

The Freedom and Travel toilets use a 12V DC battery instead of mains power.

Clause G4 aims to protect people from illness or discomfort caused by inadequate ventilation.

The toilet features an internal fan that activates automatically when the seat is lifted. This extractor fan removes fumes from the incineration chamber, directing them through a catalytic converter that filters out any remaining odours and emissions. All waste is heated to 550°C, reducing it to inert ash within the chamber. The internal fan will run until the toilet has cooled down.

Cinderella Comfort and Cinderella Travel are based on a closed air system. This system with a controlled intake and exhaust system ensures optimal incineration and energy consumption.

All Cinderella toilets are supplied with their own ventilation system. The ventilation pipes and installation instructions are supplied with every toilet and the instructions can be downloaded from our website https://www.ecoash.co.nz/installation

The Cinderella Freedom toilets are supplied with their own ventilation system including a room ventilation terminal/duct, exhaust pipes to ensure optimal incineration and ventilation. If you have a Freedom toilet and have an extractor fan in a bathroom where the toilet is located simply do not turn on the extractor fan when the toilet is in use. The reason for this is not that it will cause illness or discomfort to people, but this toilet draws in oxygen under the toilet to help with the burning process and a bathroom fan extracts oxygen from the room. This could result in the toilet pausing until it is reset with good oxygen flow.

Objectives of clauses within Clause C is to protect from a fire.

The Cinderella toilets have the following built in safety features to prevent a fire or hazard:

• The incineration process is inactive while the toilet lid is open. The incineration will not start until the seat and lid are closed.
• The hatch to the incineration chamber CANNOT remain open while the toilet is still hot (e.g. during cleaning).
• This is only possible when the toilet has cooled down and the fan has stopped.
• Should a ventilation problem arise and the internal temperature of the toilet increases to more than 105 °C, incineration will be interrupted and a warning message displayed. This is secured by a mechanical cut-off switch directly connected to the power supply. This situation requires a manual reset to ensure the ventilation issue is addressed before the toilet can be used again.
• If the ash container is improperly positioned after emptying, incineration will not start and a warning light and message will be displayed.
• If the combustion chamber hatch mechanism gets jammed or is prevented from closing properly, incineration will not start and an error message will be displayed.
• The Cinderella smart software includes a ’’watchdog’’ function that monitors the temperature while incineration is taking place. If any deviations from the normal temperature range are detected, this will immediately result in the incineration stopping and a warning message being displayed.

Section 12 prohibits the operation of a high-temperature hazardous waste incinerator.

However, high temperature is classed as >850 degrees. Our toilets operate ‘up to 600 degrees’ it wouldn’t qualify as a ‘high temperature’ system.

Cinderella Comfort and Cinderella Travel are based on a closed air system. This system has a controlled intake and exhaust system and ensures optimal incineration and energy consumption.

Cinderella Freedom has the same exhaust system but it uses an air inlet vent. This vent has an adjustable lid on the opening that can be closed ONLY when the toilet is not in use.

The Norwegian energy commission has tested the flue emissions from the toilets and emissions are well below international standards.

At ground level, carbon monoxide (CO), sulphur dioxide (SOs) and hydrogen flourid (HF) are significantly lower than environmental quality standards for air. Nitrogen dioxide emissions (NO2) may temporarily exceed the Norwegian air quality standard in adverse dispersion conditions, but the concentration at ground level is probably on par with emissions from a modern wood boiler. Greenhouse gas emissions co2 (CO2) and methane (CH4) are very low. Emissions of hydrochloric acid (HCl ́-) and ammonia (NH3) are low and is not considered to have any adverse health or environmental effects. (Test Report available on request)

The catalytic converter is the primary air duct between the incineration chamber and the appliance flue terminal and stops any bad odours. We give detailed information on the toilet maintenance on our website and in manuals supplied with the toilet, along with the ability to book a service as required.

a) From a cold start the toilet will use 180 grams per incineration.

b) If the toilet is used while it is still hot it uses less gas. For example, 2 or 3 consecutive flushes will use 150 grams per incineration and 4 -5 flushes will use 130 grams per flush.

a) Based on NZ power pricing average, $.21 cents per kWh and one incineration from cold uses 1.41kWh the cost would be $0.29 cents per flush.

b) If the toilet is used while it is still hot it uses less power. For example, 3 consecutive flushes will use 2.72kWh (.90 kWh on average per flush) $0.19 cents per flush.

No need to use harsh chemicals, the bowl/seat/outside of toilet can be cleaned with water or vinegar. Wet wipes can be used for an easy clean and incinerated after use.

We also offer a biological cleaner from URIMAT that is safe for your toilet and the environment.

If hygiene products are deposited into the toilet, they will burn with the next incineration cycle. Pure cotton products are okay, but sanitary liners containing plastic will potentially block up the catalytic converter.

We advise after every 50 liners used. Best practice would be for a 2 - 4 person household to empty the ash pan once per week, when doing the weekly cleaning.

Yes, if the waste sits in the liner without ‘flushing’ the moisture from the waste will soak through the liner within 20mins and this would make the liner stick to the bowl. The golden rule – one usage, one liner, one flush. The risk of over-filling is to great and wrong usage means warranty is void. When too much urine enters at once it can come very close to the rim of the container and boil up on to the heat element that then wears down much quicker.

The Cinderella incineration toilets operate at temperatures between 550°C and 600°C. This high heat ensures that all waste is thoroughly incinerated, leaving behind only a small amount of sterile ash.

No, you don’t need to separate urine and faeces. Our incineration toilets handle all waste together safely and easily.

Yes, it has passed all tests required for safety.

a) As soon as the first person has closed the lid and flushed the toilet, the 2nd person can use the toilet. The incineration process will pause when the lid is lifted and start again when flushed.

b) If more than 2 people use the toilet it would be good to leave it a few minutes between uses.

When the lid is lifted the incineration will stop and the fan will keep running, meaning that the bowl will be warm to touch. But will not burn you.

No, the fan will remove all odours from the room.

The average AMP consumption is 1.3 AMP and the incineration time is 1.17 hours. Based on this you will need 1.52 AMP hours per flush. (Calculation 1.3 x 1.17 = 1.52 AMP hours).

From cold it will use on average 250ml per incineration. If the toilet is used while it is still hot it uses less diesel.

Please refer to our "Regulation Q & A" section with the FAQ tab. Please ask your local council regarding your situation.

The pipe should be a minimum of 600mm above the intersecting roof line. Then the flue cap on top of the pipe.

For the Freedom LPG toilet the maximum height should be 5 metres and NO bends allowed.

For the Comfort toilet the maximum height should be 6m with NO bends or 5m with a bend no greater than 45 degrees.

The flue can be painted.

The Comfort toilet does not need to be secured to the floor.

The Freedom toilet needs to be screwed to the floor.

Ensure the toilet can be easily disconnected and taken outside for a deep clean or maintenance.

Our Travel models are secured permanently.

It’s made of parchment paper and a wax coating. They adhere to Cinderella strict demands for quality, environmental factors and production methods. These bags are the result of many years development and are designed to ensure a long life for your Cinderella toilet and the need for service to a minimum.

Box of 500 liners is $95 (0.19 cents per liner). However on subscription they reduce to $0.15 cents per liner ($76 per box)

The incineration process leaves an inert ash, no pathogen or bacterial/virus left behind.

From the time the lid is lifted, until the incineration has finished and the toilet has cooled down to ambient temperature (approx 1 – 2 hours)

450 litres for a household of 4 people.

Normally 40 - 70 minutes normal time range. Plus a cooling down period.

Occasionally a very faint burning scent may occasionally be noticed outside during operation - similar to the smell of a candle or a match being lit. The catalytic converter is designed to minimise odours, and following the recommended cleaning and maintenance guidelines helps ensure it continues to work effectively and keeps any smell to a minimum.

a) 4 people can use the toilet in an hour, any more people and the incineration chamber may overflow, as its capacity is 5 litres.

b) If the estimated number of users is 8-10 people per hour, 2 toilets would be needed.

Many Cinderella Comfort toilets have been installed in Air BnB homes but it’s important to note that the guests must be shown how to use the toilet. Contact us for more in depth instructions for Air BnB users. There is a 1 year warranty on toilets used in Air BnB or semi commercial situations.

A properly installed and maintained Cinderella incineration toilet is covered by a three-year warranty covering any defects in materials or workmanship.

For a semi-commercial situation like AirBnB there is a 1 year warranty

Based on a full bottle 9000 grams of gas, 180 grams per flush 50 flushes, 150 grams 60 flushes and 130 grams 69 flushes. This is an approximate guide only.

When the the toilet is warm it uses less gas to do any subsequent incinerations.

No, you will have to purchase your own 12V Deep Cycle lithium battery. This provides energy for the internal spark plug that ignites the gas. It also runs the fan and controls.

Alternatively to using a 12v Battery if you have 240v mains our solar power you can use a Converter 240v to DC 12v. It needs to be a quality converter.

No, a car battery is designed to create an initial short sharp burst in power, but the deep cycle battery is able to withstand many more charge and discharge cycles.

Alternatively to using a 12v Battery if you have 240v mains our solar power you can use a Converter 240v to DC 12v. It needs to be a quality converter.

Ideally for 2 persons regularly using a Freedom toilet you will need a 12V Deep Cycle Battery with 60AMP hours, connected to a 90Watt solar panel. If you have 4 people regularly using the toilet we suggest a 12V Deep Cycle Battery with 90AMP output, connected to a 120Watt solar panel. A solar panel charge controller should also be installed.
