Managing Your HomeBiogas 

Congratulations! You are now officially a HomeBiogas system owner.

Cheers for choosing to take part in the world’s revolution of using self-made renewable energy. Now that you have your HomeBiogas up and running, here are few pieces of valuable information to help you maximize your system.

What to feed your system?

Everything! Food scraps such as rice, cheese, vegetables and fruits, peels, meat, bones, eggshells, cooking oil, and any other “wet” food waste.

Citrus fruits – The daily allowed amount is up to 50 ml (1 fruit per day). Large amounts of citrus peels, contain antibacterial oils, that can affect system performance. 

Frying oil – The daily allowed amount is up to 50 ml. Large amounts of cooking oil can lower the pH level in the system and slow digestion down.


Feeding food scraps to Homebiogas system



Initial operation

After the activation, you should wait for the production of gas and the swelling of the gas bag. 

Once the gas is flammable, you can start feeding with half the daily recommended for the first two weeks. 

After this, you can daily feed according to what’s listed in the table below:



Operation during winter time

  • A temperature below an average of 22C, requires the addition of an electric water heater
  • When the temperatures reach below 18C, no feeding is allowed (unless there a heating element is added)



Handling your system

If the gas is not flammable, the gas in the bag must be emptied by opening a system tap and detaching the pipe from the side facing the house pipe. It is important to stay away from the place while the gas is being removed. When the gas bag is empty, close the system tap, connect the pipe and wait again for a few more days for the gas to form and inflate the gas bag. When flammable, feeding begins. If not flammable, contact the company’s customer service.

The system must be full of water at all times, so that the liquids flow through the fertilizer outlet all the time. 

If the flame is not stable, the system pipe must be closed, a pipe leading to the house should be disconnected and liquids drained by the shake of both pipes. If a fluid discharge point is installed (in a bucket) – open the T connector piping to drain the liquids for about 5 seconds, and close it again.

Bio- Fertilizer – the liquid that comes out of the system. The fertilizer should be diluted before use at a ratio 1:5 to water. For mature trees the bio-fertilizer can be poured directly.

The gas filter located in the Over-flow unit should be replaced: 


HBG 2 - Once every 6 months or when there is a bad smell; HBG 4 - Once every 3 months or when there is a bad smell; HBG 7 - Once every 1.5 months or when there is a bad smell



For Your Safety

Do not light a fire in the system area within a 5-meter radius, do not climb the system, do not drink the bio-fertilizer coming out of the system, do not use sharp objects that may damage the system, do not breathe the gas emitted from the system when unloading, the system should be used according to the instructions only. Product warranty is approximately 2 years; one year on the stove. (provided on proper use)
