LSHTM-2021-11 - Solar Thermal Project

Tender description

LSHTM-2021-11 - Solar Thermal Project Recommission an existing Solar Thermal heat recovery system based at Tavistock Place, London. There are three existing Domestic Hot Water (DHW) Storage Cylinders (total capacity 2.4m³) located within one of the basement plantrooms that are to be reused following inspection and possible internal descaling. The existing DHW pre-heat Storage Cylinder is to be converted to a Thermal Store that shall primarily supply thermal heat from the proposed recommissioned Solar Thermal heat recovery system at a storage temperature ceiling of nominally 65°C to be then transferred on demand indirectly to the remaining two DHW Storage Cylinders as a priority heat supply source and independently of the existing NG Boiler(s). The existing NG fired Boiler(s) shall be configured to augment any remaining DHW thermal heat requirements in order to meet the combined delivery temperature of DHW outside of the useful prioritisation of the Solar Thermal heat recovery system. It is proposed to reconfigure the existing primary hydraulic heating and DHW supply to the deployed three DHW Storage Cylinders.
