The Ekolet YV indoors composting toilet is a stylish, environmentally friendly and odor-free indoor toilet designed for continuous year-round use. There is sufficient capacity for continual use by 1–7 people. The use of a hand shower is possible and its installation in the bathroom is even desirable because it makes cleaning particularly easy. The toilet is made up of a porcelain toilet seat in the washroom itself plus a rotating, four-compartment composting tank beneath the floor. Therefore, the final product is 100% composted soil, because the after-composting is done in the system. The electrically assisted air circulation through the ventilation pipe keeps the toilet completely odor-free. A large part of the liquids evaporates with the air flow that is ensured by small electric fan. The rest of the liquid can be led into a gray water system of the house, among the washing water. The external appearance of the toilet is just like that of an ordinary water toilet. No additives are needed, and no sewerage pipes or water for flushing.
New compartment rotated into position
When one compartment in the composting tank is full, a thin layer of soil or turf is sprinkled over the top, and a new compartment rotated into position. This happens at intervals of about a year. When all four compartments are full, the compartment with the oldest compost will be taken out through a hatch on the side. The four compartments allow sufficiently long, natural composting and the end product is ready to be used as a fertilizer directly to plants. The biologically cleansed liquids, can be led to a gray water system of the house, among the washing water.
Simple and reliable in construction
The Ekolet indoors composting toilet is simple and reliable in construction, and can also be used during prolonged power shortages. It contains no parts that could break or become blocked and prevent the use of the toilet. The need for floor space is small due to the vertical design. The Ekolet also effectively reduces the amount of the carcinogenic radon gas by improving the ventilation in the foundations of the house. The material is polythene plastic reinforced by steel and can be recycled.
Check with the local municipal authorities whether or not you need a permit to install a composting toilet.
Underneath the toilet-room one must have a space for the composting tank of at least 130 cm x 130 cm square (125 cm x 125 cm when extremely tight) with a minimum height of 220 cm. This space should be warm and have a floor drain.
The composter is installed on a floor supported by four steel posts. The maximum weight of the composter is 1,400 kg. The weight under normal usage is 700–800 kg. All parts of the composter can be carried in through an opening of 60 cm x 130 cm.
The composter has an electric fan (8 W) that fans air into the 160 mm wide ventilation pipe attached to the lid of the composter at a rate of 15-30 cubic meters per hour. The ventilation pipe starting from the centre of the lid can be positioned according to the demands of the space. The ventilation pipe must always be directed upwards in such a manner that the ventilation may function naturally during electric shortages. It is advisable to insulate the ventilation pipe. The fan can be powered also by an electric solar panel. Most of the liquid will evaporate with the ventilation and rest of the pre-cleansed liquids are extracted from the composter via an exhaust hose (ø 19 mm) and can be mixed with the other household waste water (grey water).
One side of the composter must be accessible for emptying of the composter. A full composting compartment provides you with 150–200 litres of composted soil (three wheelbarrows). One 230 V 50/60 Hz electric outlet (or connection to solar power) located indoors near the composter is needed for the electric fan.
Porcelain toilet seat
In the picture a toilet seat made from porcelain above the composter. The diameter of the composter is 1230 mm. The centre of sewage pipe (inner diameter ø 200 mm, outer diameter ø 206 mm) is 350 mm from the centre of the composter, 230 mm from the rear edge of the seat, and 290 mm from the front edge of the seat. The width of the white porcelain seat is 357 mm and the height 400 mm. Sitting height is 440mm.
If two seats are connected to one composter, the distance of the centers of the sewage pipes is 700 mm (when opposite to each other) or 485 mm (when next to each other).
Dimensions of the composter
Total volume 2000 litraa
Installation height 215 cm
Diameter 123 cm
Weight 160 kg (when empty)
The ventilation of the toilet room is effected via the toilet seat. If you want to install additional ventilation to the ceiling, it is possible to connect the additional ventilation pipe ø 100 mm to the composter that is situated under the floor. This is important if you have shower in the same room with the toilet.
The composter comes complete with all the necessary parts and instructions excluding the 160 mm diameter ventilation pipe. The assembly of the EKOLET toilet is easy and one doesn’t need to have any special skills in electric installations or sewage assembly.
