Instead, biomass
Feb 05, 2020 · Above: Biomass is organic material from plants and animals that humans burn to produce energy. Homo erectus learned how to harness the flames of burning wood to provide warmth and heat food around 1.7 million years ago, but these days biomass consists of woody plants or herbaceous crops such as willow, poplar and elephant grass, and the biogas captured from rotting food and animal manure.
Biomass is also considered a viable source of renewable thermal energy for the commercial sector. A prime historical example of this application can be seen within the Commonwealth's Agricultural Community where fuel wood has been used to boil sap into maple syrup; a ubiquitous practice on early Massachusetts farms.
On combustion, the carbon from biomass is released into the atmosphere as carbon dioxide (CO 2). The amount of carbon stored in dry wood is approximately 50% by weight. When from agricultural sources, plant matter used as a fuel can be replaced by planting for new growth.
Generally, a correctly sized and installed biomass boiler system in a well-insulated property, combined with a good local and sustainable fuel source can definitely present a sound long term investment option when replacing an oil, LPG or electrical heating system and a great method of reducing your property's carbon footprint.
