A biocide suitable for use as a heat pump flushing solution comprises: 75 to 98 % by weight water, 0.1 to 25% by weight hydroxide peroxide and 0.01 to 10% by weight particulate silver. The biocide is particularly effective for use in ground source heat pumps of the closed-loop or open-loop types. Also claimed is a method of commissioning a ground source heat pump comprising the steps of; flushing the heat pump with water, measuring the bacterial levels instantaneously using a bioluminescence technique and a luminometer, flushing the heat pump with a biocide of the present invention, measuring the bacterial levels again and introducing the thermal fluid into the ground source heat pump ground loop. |
