Green wood chips or dry wood chips, what is the best fuel for heating boilers? Generally the answer depends upon scale. Green wood chip boilers and fuel handling systems require more infrastructure, which means both a larger investment and larger requirements for floor space. Green wood chips do not require as much processing and handling […]
All Solid fuel hot water boilers must be installed with an ability to shed heat with or without the benefit of electrical power. In the unusual event a boiler exceeds its set-point temperature and the temperature is continuing to climb, an over-heat dump zone may be the only means for preventing the boiler from making […]
Storing renewable energy is one of the great challenges of the current age. Until renewable energy can be stored reliably and in massive quantities, we are not able to relinquish our use of fossil and nuclear fuels. There is no single energy storage method that can solve all of our needs, though electric batteries hold […]
What is a “Modern Wood Boiler”? Modern wood boilers use sensors, such as oxygen sensors like those found in modern automobile engines, to provide real-time combustion adjustment with separate primary and secondary air controls. Sometimes these boilers are called “lambda controlled wood boilers”. Modern wood boilers almost always use induced draft fans rather than forced […]
When it comes to wood boiler efficiency, there is no end to the number of wood boilers advertised as being “high efficiency” boilers. How could practically all wood boilers be considered highly efficient? Is the term meaningless? Buyers, even those who are well informed, must find the landscape very confusing. One might think that a […]
