Millones de hogares en el Reino Unido se podrían calentar utilizando un revolucionario sistema que obtiene la energía de ríos y lagos, reduciendo el coste en un 20%
Parece que es un sistema con bomba de calor que extrae el calor del fondo del rio. Me cuesta un poco entender el proceso.
"Water is drawn from two metres below the surface of the Thames, where latent heat from the sun is sustained at around 8C to 10C all year round. The water is filtered twice and fed through a pump, where the low-grade heat is harvested by heat exchangers, while the cooler water is pumped back into the river. The heat exchangers transfer the heat to a series of condensers, which boost the 8C to 10C heat to 45C hot water using a process of reverse refrigeration. This is used to heat domestic water piped into nearby homes. A small amount of electricity is used to power the system, but this is supplied by Ecotricity, which makes it technically zero carbon." #0
#1 Tampoco yo lo entiendo a la perfección, pero diría que es como en el aire acondicionado. Juegan con temperaturas y presiones (por los condensadores). En cualquier caso, si se ahorra todo el gas y un 20% en la factura, puede ser algo grande ¿no?
