Warm tap water service

The flexible pre-insulated pipe for warm water transportation

The Uponor Ecoflex pre-insulated pipes are secure choices for any location for conveying domestic hot water from one building to the next. Their layered construction and corrugated casing makes the pipe elements flexible. The flexible pipes are easily installed along the ground. Obstacles and retained objects can easily be avoided. Thick, closed-cell insulation layer keeps heat loss minimal and enables low trenches. Heat is transferred from one building to the next and is not lost in the ground. This makes the solution environmentally friendly. The corrugated casing withstands soil pressure well and protects the pipe element from external sources of stress. In green areas, a minimum of 40 cm depth is required. There is no need for extensive earthworks.

An alternative solution for warm tap water service is our four-pipe Uponor Ecoflex Quattro, which is conveying heating water and domestic hot water. Two flow pipes are intended for domestic hot water and the other two for heating use.
