Because silicones have a high viscosity and low heat capacities, they require more energy to pump. Silicones also leak easily, even through microscopic holes in a solar loop. Other types of heat transfer fluids include synthetic, mineral, or aromatic hydrocarbon fluids; refrigerants such as found in heat-pump systems; methyl alcohol; and Ammonia.
A fluid with low viscosity and high specific heat is easier to pump, because it is less resistant to flow and transfers more heat. Other properties that help determine the effectiveness of a fluid are stability and replacement lifetime. Illustration of a solar water heater.
