The water in Bristol harbour looks chilly. But it holds ambient heat due to latent energy from the sun. When the Castle Park Energy Centre is humming, it sucks up 133 litres of the stuff each second. Once filtered, the water passes through a dense network of pipes in the pump room.That ambient heat turns a refrigerant, in this case ammonia, from liquid into gas. The gas is then compressed, raising its temperature, and pumped through a heat exchanger which warms a separate supply of water ready to be used in homes. Its job done, the initial load goes back into the harbour some four degrees Celsius cooler.
