Viessmann boilers and a Viessmann CHP unit have been specified for 101 George Street in Croydon. The project is the tallest modular building in the world.

The equipment will provide space heating and domestic hot water to 546 apartments. George Street is a high-quality development of private rental and build-to-rent units comprised of two towers - one 38 storeys tall and the other reaching 44 storeys. The apartments are connected to a district heating system which integrates the six Vitocrossal 200 CM2 620 kW gas-condensing boilers and a single Viessmann Vitobloc EM70 CHP (combined heat and power) unit.

Each apartment draws what it needs from the district heating system via a heat interface unit (HIU). The main plantroom is located two floors below ground-level, but to accurately regulate heating-provision at the upper levels, some equipment is also located in a mini-plantroom on the roof.

101 George Street’s developer specified that the boilers should be capable of providing double the forecast peak heat demand, so that if one set of equipment should ever have to go offline to fix a fault, an identical set can immediately take over.
