Product Details

Available in lengths of 50m & 80m, our pipes have an outer diameter of 12mm, while it is also one of the most reliable fixtures available on the market. The pipes are designed to provide maximum efficiency with both a durable and flexible solution in your water underfloor heating system.

Their unique triple-layered design incorporates a rugged interior sheathed by an inner layer of high-conductivity aluminium, with a pliable exterior sheath making installation straightforward.

We are so confident in the resilience of our pipes that we back them with a 50-year warranty, meaning you can purchase with confidence.

Underfloor Heating Direct


Being 100% air tight and able to function efficiently at temperatures of up to 60°C and pressures of up to six bar, our multi-layered pipe from Varm Haus is a versatile and flexible component of our high-quality water underfloor heating systems.

The inner and outer layers are constructed using PEX (cross-linked polyethylene) and are resistant to scale, while it does not corrode nor develop pinholes, making your underfloor system more resilient. The inner layer of aluminium offers efficient heating performance and, when installed with high-quality floor insulation, will keep your home warm.

Suitable for use in low-temperature hot water systems, our 12mm pipe can facilitate a flow rate of 0.061L per hour and weighs less than 0.09kg per metre.
