Increased Efficiency For Multi-Occupancy Residential Buildings

Sirius SAT from Potterton Commercial is a range of Heat Interface Units (HIU) for the provision and control of heating and hot water within each dwelling of a residential block of flats that is served by a centralised plant room. Suitable for use in local authority building stock, a centralised system removes the necessity for individual boilers within each dwelling, allowing quick and easy access for maintenance. This method of heating also results in reduced installation costs, no flues or visible plumage and reduced annual appliance service charges. Furthermore, it is easier to integrate Low/ Zero Carbon (LZC) energy solutions, like the Andrews SOLARflo solar thermal system, the benefits of which can be distributed to all the residents.


The Sirius SAT HIU range includes eight models, depending on the size of the residential block and whether domestic hot water is required in addition to heating. No matter what size they are, the units are all compact and can be installed where space is limited, ensuring ease of installation.


For dwellings with larger hot water loads, HIU models are also available for integration with hot water cylinders.


One of the technologically advanced benefits of this product is its heat consumption meters that have the option of being able to transmit data by wireless, allowing the local metering of heating and hot water consumption in each dwelling to take place from one single position. This reduces meter reading costs and avoids possible reading mistakes. The direct consumption reading is also shown via the clear, digital display on the HIU, which helps to encourage efficient use of heating and hot water by individual residents. 


Sirius SAT comes with a range of optional extras, including a programmable room thermostat, aerial/ receiver, radio modules, weather compensation module and DHW/ cold water meter and pipework loop. With a selection of three different climatic curves and the possibility to control two different heating zones, as well as an outdoor sensor connection option, the Sirius SAT offers the very latest in energy efficiency, management and control for residential buildings.
