Heating and Domestic Water Pipe MX-4-Flex 2x25x2,3/28x4,0+22x3,0/160
Insulated heating and domestic water pipe for combination installations
MX-4-Flex is a four-pipe, pre-insulated combination pipe designed to transfer both heating and domestic water in the same structure. The pipe contains two PEX pipes for the heating network (supply and return) as well as two PEX pipes for domestic water installations (hot and cold). All pipes are pre-insulated and protected with a weather-resistant protective sleeve – a quick and cost-effective solution for underground installations. The corrugated polyethylene (PE) protective pipe in the MX-4-flex system offers high ring stiffness while maintaining a flexible structure.
MX-4-flex can be cut to the desired length without any cutting fee.
Pipe construction:
-
2 x 25 x 2,3 mm PEX – Heating pipes (e.g. floor heating, radiators)
-
28x4,0+22x3,0 mm PEX – Domestic water pipes (hot and cold water)
-
Outer casing: Ø 160 mm flexible, mechanically durable corrugated pipe (Polyethylene, PE)
-
Thermal insulation: PEX foam (0,037 W/mk) – prevents freezing and reduces heat loss
Technical specifications:
-
Operating pressure: PN6 / PN10
-
Operating temperature: Heating water pipe 90°C and domestic water pipe 75°C (temporarily 95°C)
-
Installation: Directly underground or in structures, does not require a separate protective pipe
-
Roll lengths: Available in desired quantities
Applications:
-
Combined pipelines between buildings (heating + domestic water)
-
Single-family houses, carports, storage buildings, sauna buildings
-
Agricultural buildings and industrial halls
-
Connections for geothermal and hybrid systems
Benefits:
-
One trench – four lines: saves time, excavation work, and installation costs
-
Efficient insulation ensures reliable operation year-round
-
Domestic quality – designed for northern conditions
MX-4-Flex – when you want to bring heat and water in one go, efficiently and safely.
