Abstract

An innovative low temperature district heating (LTDH) local network is developed in Nottingham, supported by the REMOURBAN project, part of the H2020 Smart City and Community Lighthouse scheme. It was proposed that a branch emanating from the return pipe of the existing district heating system in Nottingham would be created to use low temperature heating for the first time on such scale in the UK. The development is aimed to extract unused heat from existing district heating system and to make it more efficient and profitable. The 94 low-raised flats in four maisonette blocks in Nottingham demo site have been selected to be connected to this new LTDH system. The scheme will provide a primary supply of space heating and hot water at approximately 50°C to 60°C. Innovated solutions have been put forward to overcome certain barriers, such as legionella related risks and peak loads during extreme heating seasons and occasional maintenance.
