Heat Interface Units

DOMESTIC heat networks

Altecnic SmartSat electronic heat interface units (HIU) are the UK's most efficient HIU, form a volume producer, offering a number of market-leading features including floor drying setting, integral pre-payment and digital commissioning. Read more

If your goal is a lean and efficient heat network then Altecnic's SmartSat electronically controlled HIUs are really the only option.

With traditional mechanical heat interface units, there is a definite limit to what can be achieved with a mechanically operated control valve. You can play around with sensor locations, to improve things slightly, but in the end, the valve cannot act with any ‘intelligence’. Electronically controlled HIUs run sophisticated controllers that have many inputs, such as temperatures, pressures, flow rates etc. The firmware then calculates the most efficient operating parameters for the control valve. The net result is improved performance and efficiency.

Having a network with a low return temperature and therefore, wide operating delta-T, is absolutely critical to ensuring network efficiency. This has now been recognised by CIBSE in their CP1 Code of Practice for heat networks in the UK and by BSRIA in their HIU guide. The Altecnic SmartSat® HIU complies with these documents and produces primary return temperatures below 25°C when on hot water demand.

SmartSat is fast to install, easy to use and with Altecnic's renowned system design advice, can deliver the lowest capital cost with on-going operational savings.

The Altecnic SmartSat® range has compensated heating flow temperatures. If it ‘sees’ the space heating return temperature increasing, it will automatically lower the heating flow temperature. This not only saves energy, but it also ensures that the primary return stays as low as possible.

In independent tests, Altecnic SmartSat heat interface units achieved a VWART of just 29.4°C. Compared to results achieved by other HIUs on the market , we can see a major difference and therefore a major reduction in lifetime running costs with SmartSat installed within a building.
