Also ich habe einen Biomeiler mit 8 IBCs (4 fuurs BioGas und 4 zur Aufnahme des Wassers) gebaut und der normnale zweiflammige...
Biomeiler are extracting heat from a special compost heap and are therefore also known as "Compost Heating". Their function are based on the principal of composting. During this process aerobic bacteria are converting organic matter (in this case wood chips) into heat, carbon dioxide and ammonium. This process occurs everywhere around us on the ground and in the soil:
Composting is the one key natural cycle turning organic matter back into its useful components. Compost can also be used to generate biogas through anaerobic digestion.
A biomeiler is a very simple system using just pipes, water and the compost heap from shredded shrubs. The only moving part is a standard central heating circulation pump. This simple construction reduces maintenance cost and the risks of failure.
A biomeiler "runs" for a year to 18 months producing enough heat for a house and the water. In the warmer parts of the year there will be more heat than required and it could be stored for the winter or one might share it with neighbours to help them reduce their energy bill and CO2 footprint.
Biomeilers are not the solution for everyone. A biomeiler needs some space in the garden or a back yard. Often biomeilers are shown as large round heaps, but they can be equally square or rectangular and more compact to fit into corners and be hidden away.
Biomeilers are certainly one of the most economic solutions to generate clean heating energy.
A biomeiler with 4 kW output generates around 35,000 kWh in 12 months.
This is a comparison for systems and fuel cost in the UK. In the table below we have compared the total cost of different types of heating systems (note - the investment and labour only includes installation of the boiler, water tank if needed & direct accessories):

You can build your own or you can order one from one one of our certified partners.
For both ways there is an add-on option - you could organise the building of your biomeiler as a workshop and reduce the cost of building it in several ways.
If you want to build your own you can find all the parts needed in our on-line shop.
