Objective
Nicholls were asked by the 180 bedroom Runnymede Hotel to design, supply and install an Open Loop heating and cooling system to support the hotel’s high heating/cooling and hot water demand. Phase One of the project to support the hot water system with the ability to expand the system in the future.
About the project
Due to the close proximity of the River Thames Nicholls designed a system to utilise the river water for the Ground Source Heat Pump system. The river pods were designed to move with the height of the river water. The abstraction pumps are capable of extracting enough water to support a 450kW Heat Pump system in the future.
