HIUs eliminate individual boilers in each flat, reducing capital costs and freeing up valuable space. With no gas supply infrastructure or flues required, construction is simpler and more cost-effective for apartment blocks and residential developments. At just 600 x 500 x 312mm, our MTA HIUs fit neatly into a cupboard. Centralised heating means one efficient plant room instead of servicing hundreds of individual boilers—ideal for social housing, student accommodation, and new build projects.

Residents enjoy instant domestic hot water (DHW) without waiting, plus precise space heating control for underfloor heating (30-45°C) or radiators (45-80°C). Our twin plate HIU design operates quietly with no combustion in dwellings—eliminating gas pipes and carbon monoxide risks. Advanced diagnostics with remote monitoring enable quick issue resolution, often without site visits.

District heating networks with HIUs enable efficient heat generation from combined heat and power (CHP), renewable sources, or heat recovery systems. Modern HIUs are specifically heat pump optimised for low temperature heat networks, ensuring exceptional return temperature performance for maximum efficiency and reduced operational costs. Our MTA Plus achieved the lowest VWART (Volume Weighted Average Return Temperature) scores in BESA testing—26°C (high) and 24°C (low)—confirming it as the UK's best performing heat interface unit for fourth-generation heat networks. As the grid transitions to renewable energy, your entire building benefits automatically.

Integrated heat metering ensures residents pay only for the energy they use, promoting fairness and energy-conscious behaviour in apartment complexes. Optional remote connectivity and building management system (BMS) integration provide real-time performance data for continuous heat network optimisation whilst reducing maintenance visits—perfect for managing communal heating across residential buildings.
