NEWS | HEATING Zeroth ambient network installed in Poole loft apartments A Zeroth Energy System, featuring an ambient network of water-to-water heat pumps, has been installed in the Harbour Lofts apartment scheme in Poole, Dorset. The central loop of the Zeroth Energy System, designed by GDHV, runs at 25C, rather than the 80C of a traditional hightemperature system. GDHV claims this reduces heat loss by up to 90%. The design features an air source heat pump and buffer tank in the plantroom, and individual air source heat pumps in the apartments. GDHV worked with Thermal & Acoustic Solutions to design the system, which uses wet emitters and Floating thermal stores win energy challenge Hot Hearts system of sea-water basins functions like a giant thermal battery heat-distribution channels during the the national energy grid in light of The Hot Heart team, coordinated by CRA-Carlo Ratti Associati, included Schneider Electric, Ramboll, Transsolar The international Helsinki Energy Hot Heart concept proposes creating giant off-shore batteries that double up as thermal baths heating, with the aim of decarbonising the The other three winners were Hive, A carbon-neutral heating solution that uses water reservoirs as thermal batteries is one of four schemes to win the Helsinki Energy Challenge, and a GSHPs are underestimated Ground source heat pumps (GSHPs) should be treated like a new type of utility, according to energy analysts Regen. Its research claimed that the potential of GSHP technology to meet the challenge of decarbonising heat had been underestimated, and that giving it the same access to existing infrastructure as utilities such as water and gas would help reduce installation costs and make it more economically attractive. Policymakers and industry analysts have often focused on air source heat pumps because of their lower capital costs and perceived easier installation. But new installation approaches that share ground array infrastructure could unlock the advantages of GSHPs for more consumers and the electricity system, says the report. Regen argues that GSHPs could reduce peak electricity demand for heat by at least 10%. With a new system design based on shared infrastructure, and GSHPs could revolutionise how we heat our homes and businesses, said Regen director Johnny Gowdy. needs from the sea, and using solar an energy-transition management model based on investments in clean heating 3 of thermal battery: renewable energy is converted into heat, stored in the basins, and withdrawn through the citys Smart Salt Citys solution is an energy system with a novel thermochemical energy-storage technology charged by Hydrogen boilers to be installed in demonstration homes The semi-detached pilot homes near Gateshead involved in a number of trials, including 46 April 2021 www.cibsejournal.com CIBSE April 21 pp46 Heating news.indd 46 26/03/2021 14:43
