Thanks for your interest in purchasing a Homebiogas system from Quality Solar and Plumbing.
I have had a system operating at home since August 2018 and can personally testify that;
- The gas burns odourlessly – (6 monthly replacement of the activated carbon filter is recommended)
- The operation and maintenance is exceedingly simple
- It is a very rewarding feeling to be producing home-made cooking gas
Although the technology and operation is very simple, there are a few things worth knowing before completing your purchase.
1. In order to fill and activate the system, you will need 1200 litres of water and 100 litres of fresh animal manure from grass eating animals (cows, goats, sheep, horses or pigs)
2. The gas is considered a “wet” gas so the pipe running from the Homebiogas unit to your cooking appliance will need to be run at a continual grade with the ability to occasionally drain the condensate. If the cooker is uphill from the system then this can easily be achieved with the supplied fittings. If the cooker is down-hill then some extra fittings may be required. These are easily available from most rural or irrigation store. 20 m of piping is included.
3. The system comes with a Biogas burner. Conventional burners will need to be modified. Information on this is available if required.
4. Initial activation temperature is ideally 25 deg or more. If you are activating in winter in some areas a 300W aquarium heater is required just for the initial activation. (about 3-4 weeks) Once activated, an average of 20 deg is OK for continued operation. In colder areas the aquarium heater may be required, and is an excellent use of surplus solar power if available.
5. I keep an LP gas bottle and burner as a standby, using Biogas whenever there is gas in the system. In the event of a big cook-up, or, if I have been away and was unable to feed the system then I have a back-up. Sometimes also, multiple burners are required. The Homebiogas system is recommended as an additional supplement gas supply.
6. The amount of gas production is subject to variable such as ambient temperature, and the type and quantity of feed you put in to the system. No absolute guarantees can be made about the quantity of gas produced. The hourly cooking time will depend on if the burner is flat out, medium or low etc…
