Generate Biomass boiler
A Biomass boiler burns logs, pellets or chips and works in the same way as a conventional gas or oil boiler which powers a central heating and hot water system.
If you choose to burn logs, you will normally have to light and fill your stove or boiler by hand. Pellets are an easier option than logs as a pellet boiler can light itself and run automatically in much the same way as a gas or oil boiler. Wood chips are not suitable for heating a single house, but can be used to heat commercial buildings or groups of houses.
A Biomass boiler that provides central heating and hot water and has an automatically fed pellet boiler will cost between £7,000 and £13,000 including installation. A manually fed log boiler system that provides central heating and hot water will cost around £11500 including installation.
Logs normally work out cheaper to buy than wood pellets, but costs are dependent on wood supplies. They are normally delivered by the truck load and a dry space is required to store them in. An average truck load cost somewhere in the region of £200 but you can save money by buying unseasoned logs and letting them season for at least a year if space is not limited.
Wood Pellets can vary as the price will depend mainly on the amount of pellets ordered and the method of delivery. Buying a few bags at a time makes this an expensive option so the most cost effective way of using this type of fuel, is to have a large fuel store that will accept several tonnes of pellets at a time. These will be delivered by a tanker and will cost somewhere in the region of £190.
Biomass boiler Advantages
- Biomass makes less impact on the environment and has much lower emissions than burning fossil fuels because wood emits the same amount of carbon dioxide when it is burned, as it absorbs whilst it is growing. This makes the biomass process very sustainable as new plants can be planted and grown whilst older plants are felled and used for fuel.
- Although biomass most commonly uses wood, it can also use animal waste and industrial by-products which helps to reduce the amount of waste disposed of, at landfill sites.
- If you live in a rural area which is not connected to the mains gas network, a wood fired heating system could provide a good option for your central heating and hot water requirements.
- Using biomass reduces dependency on fossil fuels and due to global dependency; prices of fossil fuels are likely to keep increasing.
Biomass boiler Disadvantages
- The initial cost of a biomass boiler and heating system can be high.
- Biomass boilers are suitable for any type of home but you will need space to store your fuel and if you are using pellets, you will need space for a hopper for automatic loading.
- Biomass fuel costs can vary depending on your location and the distance you are from your supplier Biomass fuel is always cheaper if you buy it in large quantities but the financial outlay is greater, if you choose to do this.
- Wood fired boiler stoves require manual lighting and loading.
