Centralised boiler system improves energy efficiencySuitable for integration with a wide range of renewable technologies, the latest Tenantherm space heating and hot water system for apartment blocks and social housing developments is a compact, fully integrated Heat Interface Unit which enables efficient heating and hot water to be supplied to each apartment from a centralised heat source.

As gas boilers are no longer required in individual apartments, Armstrong says that all problems and costs associated with mandatory annual gas safety inspections are eliminated. And as Tenantherm units fully separate each tenant’s system from the landlord’s system they also provide improved billing, energy efficiency and tenant comfort.

Individual metering — for both energy and water — is available, providing separate billing for each property. A range of meter reading options is available, including manual, GSM, radio or centralised/BMS reading using RS485 bus communication. And Tenantherm’s built-in technology also provides the building manager with the capability to offer the apartment occupant the use of a pay-as-you-go smart card. In addition it enables the tenant to control heating levels remotely, using SMS, for better management of their energy consumption and comfort.

By harnessing the greater energy efficiency opportunities of a centralised system, Armstrong says that Tenantherm can assist local authority and social housing landlords to achieve their carbon reduction objectives. Energy efficiency of the centralised system is made possible through Armstrong’s MBS heating solution which features integrated control of low carbon condensing boilers and variable speed pumps.

Design of the Tenantherm units ensures the appropriate return temperatures to enable boilers to operate in their most efficient condensing mode, offering overall carbon savings compared to individual gas boilers in each property. Tenantherm units can also integrate easily with other low and zero carbon renewable heating solutions such as solar thermal technology, heat pumps and CHP.
