Radiant

Radiant is the most popular form of hydronic heating, this method circulates hot water underneath the floor to maintain a comfortable temperature and eliminates drafts. Radiant heating can achieve very high efficiencies by consistently supplying a large mass with low temperature heat. Radiant can be described as:

• Quiet
• Consistent Tempurature
• Hypo-Allergenic
• Draft Free
• Comfortable

Radiant heating has a number of advantages: it is more efficient than baseboard heating and usually more efficient than forced-air heating because no energy is lost through ducts. The lack of moving air can also be advantageous to people with severe allergies. Hydronic (liquid-based) systems use little electricity, a benefit for homes off the power grid or in areas with high electricity prices. The hydronic systems can also be heated with a wide variety of energy sources, including ground source heat pumps, standard gas- or oil-fired boilers, wood-fired boilers,
solar water heaters, or some combination of these heat sources.

Biomass

Generally, wood pellets or other biomass products are placed into a chamber where an electric probe ignites the material. A microprocessor then monitors the combustion via thermostats in the flue gasses as a result adjustments are made automatically to the fuel supply and the fan speed. Hot flue gasses are then passed through a heat exchanger, so that heat is transferred from the combustion gasses to the water used in the central heating system. The hot water is then circulated around a standard central heating system. The use of biomass for energy causes no net increase in carbon dioxide emissions to the atmosphere.When plants die, the process of decay releases the energy stored in carbohydrates (made from photosynthesis) and releases carbon dioxide back into the atmosphere naturally.
