Renewable heating systems use energy sources that are naturally replenished, such as solar, wind, and biomass. These systems provide heating for residential and commercial buildings, reducing reliance on fossil fuels and lowering greenhouse gas emissions. Common types include solar thermal systems, which capture sunlight to heat water, and biomass boilers, which burn organic materials for heat. Another popular option is heat pumps, which transfer heat from the ground or air into buildings. These systems are efficient and can provide both heating and cooling. By utilizing renewable resources, these technologies contribute to a more sustainable energy future.
