In this week’s #FridayTech, we’re highlighting a smart, space-saving solution for hot water storage for heat pumps: the Sunamp Thermino X Plus, now fully compatible with Tongyi’s R290 air-to-water heat pumps.

This integration offers more than just convenience—it brings high performance, compact design, and long-term sustainability to your domestic hot water system.

💡 The Problem with Traditional Cylinders

Hot water cylinders are often the weak link in efficient heating systems. They take up too much space, lose heat over time, and aren’t ideal for modern homes—especially where space is tight.

That’s why forward-thinking homeowners and developers are looking for hot water storage for heat pumps that’s compact, responsive, and energy-efficient.

🌡️ The Smart Solution: PCM Technology

The Sunamp Thermino X Plus replaces the need for a bulky cylinder. Inside is a Phase Change Material (PCM) that absorbs and releases heat as it melts and solidifies—similar to a gel handwarmer, but far more advanced.

It stores up to 4× more energy than water, delivering hot water instantly, at mains pressure, and with very low heat loss.

🔗 Perfect Pairing: Tongyi R290 + Thermino X Plus

Together, Tongyi’s R290 heat pump and Thermino X Plus form an ultra-efficient, low-maintenance hot water system:

  • High-Temp Ready: Tongyi delivers water up to 75°C, perfect for fully charging the PCM unit.
  • Compact Design: Thermino is up to 4x smaller than traditional hot water tanks.
  • Energy-Saving: With a COP up to 5.33 and A+ efficiency, the system can save up to 1000 kWh/year.
  • Quick Installation: No venting, discharge pipes, or annual inspections required.
  • Long-Lasting: The PCM core is tested for 40,000+ cycles—that’s over 50 years of use.

If you’re searching for reliable, modern hot water storage for heat pumps, this is the setup you’ve been waiting for.

🌱 Built for a Sustainable Future

Both components support low-carbon living:

  • Tongyi’s R290 refrigerant has an ultra-low Global Warming Potential (GWP) of 3
  • Sunamp’s PCM is non-toxic, fully recyclable, and comes with a 10-year warranty
  • The system is compatible with solar PV and smart energy diverters, allowing you to store surplus electricity as heat

This makes it an ideal solution for net-zero homes and energy-conscious households.
