Biomass Heating Installation and maintenance
Exothermic Installations Ltd professional installation and maintenance of all types of Biomass heating systems in the Swindon, Newbury and surrounding areas.
The term Biomass encompasses many types of organically derived energy. In this particular case we refer to woody biomass in the form of log gasification, wood pellet and wood chip fuels. Wood in all its forms is probably the lowest carbon of all the fuels. When burnt, wood releases the same amount of carbon as it does it it were left to decay naturally.
Wood burning technology has come along way since the days of the log stove. Modern boilers are microprocessor controlled with lambda sensors, weather compensation, ash compactors, automatic feed, automatic ignition etc. They are fully automatic in operation, burn extremely cleanly and require minimal user involvement. They can also be integrated perfectly with other technologies like solar thermal.
Biomass - Log Gasification boilers
Where a large quantity or "batch" of well seasoned logs (typically 20% moisture) are loaded into a boiler and fired. Once fired, it is completely automatic. In the first phase the logs are burned thus heated, giving off gasses which are then secondary burned to give off more heat, as well as cleaner flue emissions. As the logs are burned with such a high degree of control there is little ash remaining. What there is can be spread on the garden as it contains many beneficial trace elements. The heat generated by the batch burn is more than is required. So the heat energy is collected and stored in a buffer or thermal store unit, where it provides hot water and heating as required. The boiler may only need firing every few days, even during the winter months. A tonne of logs cost approximately £80 will provide around 4,100 kWh (depending on wood used) of heat or about 2 pence/kWh. Get in touch today for installation or maintenance of your log gasification boiler.
Biomass - Wood Chip boilers
Semi dry wood chips (typically 30% moisture) are fed from the fuel storage area via an auger to fuel the boiler. Here they are automatically ignited and burned. The boiler modulates or varies its output to suit demand. The heat produced is best stored in a thermal store or buffer unit where it provides hot water and heating as required. Wood chip boilers are normally used for larger installations typically 25kW plus. A tonne of wood chips cost approximately £110 and will provide 3,500 kWh of heat or about 3.1 pence/kWh. Contact us today for installation or maintenance of your wood pellet system.
Biomass - Wood Pellet boilers
Very dry compressed wood pellets (typically 10%moisture) are fed from the fuel storage area via vacuum tube to fuel the boiler. Here they are automatically ignited and burned. The boiler modulates or varies its output to suit demand and also varies the flow temperature of the water produced for the heating depending on weather conditions, known as weather compensation. Because these units are so controllable they can be connected directly to a conventional hot water cylinder and heating system. There is also the option of manual fill hoppers for fuel storage, where by small bags of pellets are tipped into a storage hopper and only requires refilling every 2-3 days during heating season because the pellets are so pure and burn so cleanly, very little ash is produced typically about 1% of initial pellet volume. This can also be automatically compacted and therefore only needs to be emptied every 3 months or so. A tonne of wood pellets cost approximately £210 and will provide 4,800kWh of heat or about 4.4 pence/kWh. Contact us today for installation or maintenance of your wood pellet system.
