e-stoves for residential properties
The e-stove uses logs to produce electricity, heat and hot water for living areas via the wood gasification technique, and via thermoelectric means in the form of maintenance-free and noiseless thermoelectric generators (TEG).
The exhaust gases from the combustion chamber are not directly fed to the stack (as in conventional furnaces), but are instead diverted into a second combustion chamber for post-combustion. Thus energy utilization from the wood is increased to > 90%.
Using maintenance-free and noise-free thermoelectric generators in the furnace.

The e-stove can be combined with any other heating technologies.
Self-sufficiency through power generation
How much power should be generated in order to be energy self-sufficient?
A family of four in a conventional single-family house consumes an average of 4,200 kWh per year.
11.5 kWh per day and 0.48 kWh per hour is expected to be generated.

To be self-sufficient, it would make sense to use a mix of electricity generators that can cover twice the daily requirement. In addition, there should be storage available capable of holding at least three times the daily requirement.
Advantage – heating with wood
Wood is considered by many to be a productive fuel, under the motto "properly utilising heat".
2.5 kg wood can replace 1 litre of fuel oil or 1m3 of gas.
Via a wood gasifier, approximately 5.2 m3 of beech wood can replace 1000 litres of heating oil or 1000 m3 of gas.
Average heating requirement
A family of four consumes about 22,000 kWh in an older home (estimated at about 200 heating days).
The requirement therefore is 110 kWh per day's heating. The e-stove generates this power within 6 hours.
Average power demand
This family consumes an annual average of 4200 kWh – 11.5 kWh per day, i.e. 0.48 kWh per hour.
The e-stove can provide this hourly requirement when in operation.
Astronautics and thermoelectrics
Thermoelectric materials are materials which generate electricity due to a temperature difference. Thomas Johann Seebeck discovered the effect in 1822 (Seebeck effect). The first technical applications using thermoelectric generators following in the mid-20th century in space probes researching regions in space distant from the sun. The generators require no moving parts, unlike many other conversion mechanisms, and therefore operate in a noiseless and maintenance-free manner, and are extremely reliable.
