On balance, greater effi ciency | Frequently, the real level of energy<br />
effi ciency is only discovered at the end of the year. Only then do the<br />
many cost factors, such as the domestic hot water circulation pump<br />
used in centralised systems, appear in the year-end bill. These are<br />
seldom marked down as domestic hot water costs. If you also take<br />

into account hidden cost factors, electrical domestic hot water systems<br />
often fair better than centralised oil or gas fi red systems. In particular,<br />
decentralised electric domestic hot water systems offer even more<br />
benefi ts – they are practically maintenance-free and enable you to<br />
make simple, consumption-based cost calculations.<br />
