Green Heating Systems Using Sustainable Resources
Wood pellet boilers and stoves are a cost-effective and environmentally friendly alternative to domestic heating systems powered by fossil fuels such as oil and gas. These multi fuel burning stoves in a variety of styles are available online.
The prices of oil and gas are predicted to rise dramatically in the coming years. Not only is their supply finite but there is increasing awareness of the environmental impact of burning fossil fuels. People looking to reduce their carbon footprint and retain control over their domestic fuel bills are seeking alternative sources of energy and one choice is a wood pellet boiler or stove.
How Wood Pellet Boilers Work
Many homes are heated by piping hot water around the building, either through a system of radiators or under floors. The water is heated by burning fossil fuel in a boiler.
Wood pellet boilers operate in a very similar way to oil or gas boilers with the main difference being the type of fuel used. Wood pellets, as the name implies, are small pieces of compressed wood which are specifically intended for use in a boiler.
Fossil fuel boilers are connected to a source of gas or oil. This might be a mains gas supply coming in from the street or it could be a private oil storage tank somewhere on the property. Which ever it is, the fuel is piped in liquid or gas form into the boiler.
Wood pellet boilers burn solid fuel. This requires a store of pellets to be kept nearby and to be delivered to the boiler in a consistent and automated manner. This supply usually comes from a large hopper which is linked to the boiler by an automated feeder system. The hopper itself must be manually topped-up from time to time.
Advantages of Wood Pellet Boilers
Solid fuel heating using wood pellets offers the following benefits:
- Reduced carbon footprint as pellets are usually from sustainable sources.
- Lower fuel costs when compared to oil and gas and the cost difference will increase in the coming years.
Disadvantages of Wood Pellet Boilers
No technology is perfect and wood pellet heating systems do have some drawbacks:
- Higher set up costs because the technology is relatively new and demand is low. However, these will be recovered through lower running costs.
- More space is required to house the boiler and pellet hopper, along with the large bags of pellets.
- Hopper must be refilled manually from time to time.
Despite these disadvantages the use of wood pellet boilers is increasing and improvements in the technology can be expected.
Wood pellets are a renewable source of energy made from biological material, otherwise known as biomass. Other types of biomass include alternative wood-burning systems, animal waste and alcohol.
It is anticipated that in the coming years more and more house-holders will consider changing their domestic heating systems to be fuelled by biomass or other renewal energy sources, such as solar power.
