Abstract
A surfactant suitable for use as an additive in the heat transfer liquid of a heating and/or cooling system, wherein the surfactant comprises a coconut-derived surfactant, the preferred coconut-derived surfactant being a non-ionic, coco-glucoside. The surfactant can be used as an additive in a heat transfer fluid of a wet central heating system or a chiller circuit at a concentration of between 800 ppm and 1500 ppm, but preferably 1200 ppm, as this has surprisingly been found to yield an optimum reduction in the surface tension of the heat transfer fluid, whilst not significantly or appreciably increasing the specific heat capacity of the heat transfer fluid.
