How SunFlow® Works

sunflow works

The perfect heating solution for new builds

Heated water flows through purpose designed multi-layer PEXb-AL-PEXb heating pipes that are either cast into a concrete slab or placed under an existing floor making it the perfect heating solution for new builds.

The water is reticulated and kept at a warm temperature via a single energy source or combination of energy sources. These include gas boilers, air to water heat pumps, diesel, wood burning or electric boilers. You can even use geothermal energy or back up with solar or wetbacks.

As the system is sealed, it doesn't require water storage cylinders. In addition water for underfloor heating is always kept separate from domestic hot water.
