Heat interface units (HIU)

Connected to district heating grids, HIUs can supply hot water to residences on demand, utilizing the same energy source that generates indoor heat for buildings.

Responsive and energy efficient

HIUs are highly responsive and capable of providing hot water on-demand. By eliminating the need to maintain a constant on-site reserve supply of hot water, HIUs improve energy efficiency, reduce costs, and make it easier for residents to monitor their own energy consumption.

Energy from wastewater

In cities where the peak heating demand exceeds the generation-potential of fossil-fuel power plants and combined heat and power systems, low-grade heat recovered from wastewater can be channeled into the district energy network. Utilizing low-grade heat that is a by-product of industrial process cooling, data center cooling, and waste incineration makes it possible for a significant part of the energy consumed to heat tap water and homes to be fossil-free.

Harnessing the power of heat exchange

By utilizing SWEP heat exchange technology, HIUs can play a greater role in district heating and cooling systems – now and in the future.

Use low-grade heat to warm tap water

Use existing infrastructure to heat domestic water

Replace fossil-fuel-burning boilers

Why choose SWEP BPHEs for your HIUs?

Compact, efficient SWEP BPHEs are the vital components in any HIU that transfers heat from the district heating network to cold tap water. SWEP BPHEs are efficient. They provide low return-temperature to the grid and have a self-cleaning effect that ensures that the building’s heating system operates optimally.

HEAT RECOVERY

Energy from data centers

SWEP brazed plate heat exchangers are one the most efficient means of recovering waste heat from liquid-cooled data centers. Recovered heat can be returned to the district heating network.
