Gasification is achieved in wood burning when gases released from the combusting wood are mixed with a regulated supply of oxygen to create a complete oxidation process.
This results in extremely high combustion efficencies and minimal of ash waste.
What fuels can I burn? Only wood or wood briquettes with a maximum humidity of 20% can be burnt in the Bio-Tec boiler. And the lower the humidity the better the combustion efficiency.

High efficiency
Due to the gasification process and unique heat exchanger design the Bio-tec achieves extremely high efficiencies; up to 91% on some models. So even if your wood comes for free you’ll be storing and burning a lot less than with a traditional wood-burning boiler, stove or range.
Easy to load The large combustion chamber and access door means that logs up to 500 mm in length can be used on standard domestic boilers. Log sizes of up to 700mm and 930mm can be used on higher capacity models.
Simple to start All you’ll need to start the Bio-Tec is a fire lighter and some light sticks. The Bio-Tec controller manages the rest of the start-up procedure making sure that the fire builds up as quickly and efficiently as possible.
Minimum of cleaning In wood gasification most of the wood is combusted so that very little ash remains in the combustion chamber or flue. If the boiler ran at full power continuously it would only need to be cleaned every three to four days. In most cases the boiler will only be fired-up every few days so that cleaning will only be required every few weeks

Modern, user-friendly controller The Bio-Tec boiler comes with an easy-to-use controller which manages the complete combustion process and regulates supply to the central heating system and hot water storage tank. An LCD screen on the controller displays key system information.

CAS 2000 Accumulation tank
An accumulation tank must always be used in conjunction with the Bio-Tec wood gasification boiler to allow the boiler to operate in the most efficient manner.
The official recommended sizing of accumulation tanks for solid fuel heating is a minimum of 50 liters of water storage for every 1 kW of rated boiler output. Hence for a 35kW boiler a minimum accumulation tank size of 1750 litres is need. To provide an additional safety level Firebird will be supplying a 2000 litre accumulation tank with the 35kW Bio-Tec boiler.
The Firebird CAS 2000 Accumulation Tank has been engineered to ensure highly efficient storage of the boilers thermal energy with the minimum of heat loss.
