    • An apparatus operable to recover heat in an ablutionary or plumbing system comprising a first pipe for carrying fluid having a first temperature and a second pipe for carrying fluid having a second temperature, the second temperature being different from the first temperature such that there exists, in use, a temperature differential between the fluid in the first pipe and the fluid in the second pipe, the apparatus comprising: a first heat transfer element configured to be thermally coupled to the first pipe and comprising an elongate portion extending in a direction away from the first pipe; a second heat transfer element configured to be thermally coupled to the second pipe and comprising an elongate portion extending in a direction away from the second pipe, wherein the elongate portions of the first and second heat transfer elements at least partially overlap; and a thermoelectric device, the thermoelectric device comprising one or more thermoelectric elements located between the elongate portions, the thermoelectric element(s) being in thermal communication with the elongate portion of the first heat transfer element and the elongate portion of the second heat transfer element and being arranged to generate electricity from a temperature differential between the elongate portions of the first and second heat transfer elements.
