When will my HomeBiogas ship to me?
We will ship sometime in late June. We will keep you updated and notify you when we are preparing to ship, at which point you can modify your shipping speed.
Does HomeBiogas pay for itself?
The simpliest way to calculate this is based on the gas production. Over the course of several years, the value of the gas you produce will pay for the unit. But there is also the value of the liquid fertilizer, which is like rocket fuel (but all-natural!) for your plants. And you will also likely save some money on trash service, because you won't need as big a green bin anymore (or maybe none at all).
Do you have to add bacteria or enzymes to HomeBiogas for it to work?
No. The bacteria that produce biogas are naturally occurring, and will grow and thrive under the right conditions (no oxygen and warmth, mainly). In this way, making biogas is a bit like composting. But adding a bacteria starter can help speed the startup process.
How easy/ difficult is HomeBiogas to set up?
It's a bit like putting together a piece of Ikea furniture, and should take about the same amount of time.
Do you offer a set up service?
Yes, if you live within 50 miles of Oakland, one of our staff can come set it up for an extra $100. Please contact us to discuss this option.
What can I use the gas for?
We recommend you use the gas with the included biogas stove. The stove can go anywhere - in your kitchen, on your patio, near a fire pit, etc. It is possible to retrofit existing appliances to use biogas. Please contact our customer service for more information.
Can I connect the HomeBiogas pipe to my stove in my kitchen and cook on just biogas?
It is possible to pipe biogas into your natural gas stove, however this should be done by a trained gas professional. HomeBiogas produces about 3 hours per day of cooking gas for one burner, so it may or may not produce enough gas to replace all your usage on a four burner stove, and almost certainly not enough for an oven. Each burner will also need a simple retrofit to ensure the right flow rate. Please contact our customer service for more information.
Do you offer installation if I want to connect HomeBiogas to my kitchen stove?
We do in some cases. We will first conduct an over-the-phone assessment to determine whether it's feasible, and if it is, we will charge $80 per hour for the installation. Installation may take anywhere from one to several hours, depending on the complexity.
Can biogas replace propane?
Propane burns differently than natural gas and biogas, and so most propane appliances are not compatible. However, it is possible to retrofit the appliance to run on biogas.
Do you sell two burner biogas stoves?
We do not have them in stock, but can order one if you'd like. Please contact our sales department.
Once I set it up, how soon can I expect to start producing gas?
This depends on many factors. Biogas bacteria like heat, so the warmer, and more consistently warm you can keep it, the faster it will start. You can also speed the digestion process by chopping or grinding your food scraps into smaller pieces before feeding them to HomeBiogas. Typically however, it will take about 6-8 weeks for the process to really get going WITHOUT inoculating/ seeding the digester with slurry from another digester. See the next question for more information on this procedure.
Is there a way to get it to start faster?
Yes, it's called seeding or inoculating. It involves filling the HomeBiogas tank with at least 1/4th slurry from another active digester at startup, instead of just water. We can do this for an extra $150.
Does HomeBiogas need to be mixed somehow?
The short answer is no. While mixing would increase the efficiency of digestion, the process will work just fine without mixing, HomeBiogas was designed to be as simple and low maintenance as possible, so it does not including a mechanism for mixing.
Will HomeBiogas produce in the winter?
This mainly depends on where you put it, and whether or not you want to heat it (which you can do with a fish tank heater). Northern California winters can be cold enough to make the bacteria stop producing if HomeBiogas is outside. We recommend putting it in a place with lots of sun. If you want to keep it producing all year, put it in a well-ventilated, heated basement or garage, ideally with floor drainage. Or better yet, in a greenhouse.
Where should I put HomeBiogas?
One of the best places is in a greenhouse, as this will help keep it warm. You can even build a hoop house out of plastic and PVC pipes over your HomeBiogas. Otherwise, put it somewhere with lots of sun, or in a heated basement or garage.
Can you help me build a hoop house?
We can do this as part of setup for an extra $200.
What is in the liquid fertilizer? Is it like compost?
The "liquid fertilizer" that comes out of the digester is rich in macro and micronutrients, and is especially high in organic nitrogen. You can think of it like animal (especially cow) manure - it will have similar benefits for your plants.
Are tax and shipping included in the price?
No. Regular ground shipping will cost about $40. When we ship you can choose if you want to pay more for faster shipping. Tax will be calculated at checkout based on your location.
