Heat generation by means of biomass combustion

Biomass understood as forest fuel used to provide heat.

Some relevant factors relating to this type of energy:

  • Renewable energy: this is renewed automatically, is infinite and also creates many jobs.
  • Economic savings: it costs much less than other energy sources such as diesel oil, gasoline or propane and also does not undergo major price fluctuations.
  • Local: energy obtained within national territory without the need to rely on foreign countries.
  • Abundant: Spain is the third European country in terms of raw material reserves.

A Red de Calor (District Heating) is a manufacturer of hot water for heating (steam for industrial processes) which supplies to different buildings (housing, industry, district of a city, etc..)

In this case, the size of the project makes the savings are even greater with biomass because of the investment/spend ratio in fuel is less, so that you can obtain much higher benefits.
