The Heating Revolution Needs the Right Pipe As Europe and North America
accelerate the shift to heat pumps, one question determines system performance:
which pipe carries the low-temperature water efficiently and reliably for
decades? The answer, increasingly, is PEX pipe — and the physics explain
why.
Why Heat Pumps and PEX Belong Together:
Low-Temperature Optimization: Heat pumps perform best with low supply
temperatures (35–45°C) — exactly the range where PEX-based radiant and emitter
systems are designed to operate. The lower the flow temperature, the higher the
heat pump's COP (efficiency), and PEX systems enable precisely that.
Minimal Heat Loss: PEX has far lower thermal conductivity than metal pipe,
reducing distribution losses in the low-temperature circuits that heat pumps
feed.
Corrosion-Free Closed Circuits: Heat pump systems use treated water in
closed circuits; PEX's total corrosion resistance protects both the pipe and the
expensive heat pump equipment from sludge and degradation.
Fast, Flexible Installation: Coil-fed PEX with Easy Expansion cold
connections installs quickly around existing structures — critical for heat pump
retrofits in older buildings.
The Retrofit Opportunity Millions of existing buildings are candidates for
heat pump conversion. Replacing radiators with low-temperature emitters or
adding radiant circuits — supplied in PEX — unlocks the efficiency gains that
make heat pump economics work.
Choose the Right PEX for Heat Pump Systems
PE-Xa Series Pipe — the reference choice: shape memory, cold expansion
connections, oxygen barrier options.
PE-RT Series Pipe — cost-efficient, flexible, ideal for emitter
circuits.
Multilayer Series Pipe — the aluminum layer adds extra oxygen protection
and shape retention for exposed runs.
A Future-Proof Investment Energy policy across Europe and North America
increasingly favors heat pump technology. Specifying Ritable PEX today means
building heating systems that are ready for the low-carbon future — efficient,
durable, and compliant with tomorrow's standards.
