The next generation water system solution

Uponor Combi Port E-Hybrid

Hot water on demand - without compromises

Next generation electronic heat interface units for low temperature systems

More comfort, less water waste: no more waiting for hot water

As buildings transition from gas to heat pumps, ensuring efficient and hygienic hot water delivery is more crucial than ever. Combining heat pumps with on-demand domestic hot water systems, such as electronic Heat Interface Units (HIU), can reduce flow rates, leading to user discomfort and increased energy consumption.
What if we could optimize tap water flow rates and boost energy efficiency at the same time?

The Uponor Combi Port E-Hybrid is the first flat station electronic heat interface unit (HIU) with an integrated electric booster on the heating side. Designed for modern, energy-efficient buildings, it delivers instant hot water, significantly higher flow rates without pressure loss, and enhanced hygiene without the need for additional booster pumps. Engineered for sustainability, comfort, and simplicity, it sets the new standard in on-demand water solutions for electronic heat interface units.

FAQs for Uponor Combi Port-E Hybrid - redefines hot water delivery for modern buildings.

Filter FAQs:

The Combi Port E-Hybrid is designed for low temperature heating systems because the electric booster increases the supply temperature to a useable level for domestic hot water generation.

The E-Hybrid boosts the low temperature heating supply to a higher temperature to provide enough heat for heating up the drinking water. Designed for low temperature heating systems like heat pumps no additional heat source or loss of efficiency will be needed for domestic hot water. Thanks to placing the electric Booster on the primary side the pressure losses on the drinking water side are reduced to a minimum and increases the maximum tapping rate.The electronic control increases the efficiency of the HIU and enables a remote access vie building management system.

High comfort - Booster on the heating side reduce the pressure losses on the drinking water side to a minimum
High tapping rate - The new heater is not limiting the flow rate anymore. Two bathrooms at the same time can be in use
Energy Efficiency - The energy efficiency of a heat pumps increases 1,5% for every degree the supply temperature can be reduced
Cost Savings - The maximum electric power can be limited during installation to reduce the connection charges
Low unit depth - With a depth of only 150mm it can be mounted inside common walls
Building management system - Integration is possible with Modbus and allows remote control and monitoring

Main benefits by audience:

Installers: Low pressure losses makes it suitable for even low supply pressure
Planners: The new Hybrid has a higher tapping rate. One HIU for two bathrooms is enough and thus saves costs.
Wholesalers: Simple and easy compact portfolio that coverage market needs in terms of low temperature heating systems.
Architects: Small cabinet allows installation inside walls
Investors: Limiting the electric power reduces the electric connection size. This reduces connection charges
End-user/Homeowner: Low pressure losses increase the comfort during tapping water

Uponor pioneered the first Hybrid Heat Interface Unit and now sets a new benchmark with the electronic Combi Port E-Hybrid, delivering instant hot water, enhanced hygiene, and superior efficiency for energy-conscious buildings.
