The benefits of decentralised generation of domestic hot water

Securing decentralised water quality – hot water without the risk of legionella

A Comparison between a 2-pipe system with heat interface units and a conventional 4-pipe system with central hot water preparation.

Decentralised heating of domestic hot water

Decentralised flow heating giving security to residential development heat network operating companies.
Saving on domestic hot water and circulation pipes from the central heating system to the residential units.
Low system temperatures in the building pipe-work network, as hot water pipes and circulation pipes are not required.

Centralised domestic hot water storage

Large storage system subject to mandatory testing by residential development landlords and property owners.
Increased effort for pipe network, as hot water pipes and circulation pipes are required.
High temperatures in the building piping network in order to maintain drinking water hygiene and avoid the risk of legionella.
*58 % energy saving with 2-pipe systems compared to central domestic hot water systems*
