US02 - Plumbing: Internal system

An efficient Domestic hot water system (ACS) is fundamental for avoiding energy loss so the hot water system is designed to have the shortest distance possible from the heating of the water to the point of use.


The maximum distance cannot be more than 11 metres. The Vivienda Verde has a maximum distance of just 9.96 metres a considerably shorter distance than what is required for sustainable home approval.
