Renewable heat is an application of renewable energy. It refers to the renewable generation of heat, rather than electrical power.
Many colder countries consume more energy for heating than electrical power. For example, in 2005 the United Kingdom consumed 354 TWh of electric power, but had a heat requirement of 907 TWh, the majority of which (81%) was met using gas. The residential sector alone consumed a massive 550 TWh of energy for heating, mainly in the form of gas. Almost half of the final energy consumed in the UK (49%) was in the form of heat, of which 70% was used by households and in commercial and public buildings. Households used heat for mainly for space heating (69%) and heating water.
Renewable electric power is becoming cheap and convenient enough to place it, in many cases, within reach of the average consumer. By contrast, the market for renewable heat is mostly inaccessible to domestic consumers due to inconvenience of supply, and high capital costs. Heating accounts for a large proportion of energy consumption, however a universally accessible market is still in its early stages.
As a biomass fuel, wood pellets become more and more popular all over the world to produce renewable heat, they can produce heat by burning in pellet stove, or produce heat by burning in pellet boiler and make the water to become hot steam.
Advantages of wood pellets:
Reduce our dependence on oil and gas.
Pellet fuel cost is not dictated by world events; therefore cost is more affordable and predictable.
Since pellet stove emissions are so low they can be burned in most areas even those with burning restrictions.
Pellet fuel has been proven to provide the cleanest burn of any solid fuel.
One ton of wood pellets has the heat value of about one and a half cords of wood and stacks easily in one third the space! This makes it possible to easily store fuel for the entire season.
Wood pellets are a clean, environmentally friendly, natural, renewable fuel resource
