FREE DELIVERY TO UK MAINLAND
Current stock: 10 packs
Inta's Pre insulated hoses are designed for external use to comply with building regulations Part L, reducing heat loss and maintaining the efficiency of Air Source Heat Pump Systems. With a water resistant finish to prevent absorption of moisture and heat loss, these hoses contribute to an efficient system and prevent unexpected costs. Properly bonding and sealing all joints is essential to prevent capillary traction, and annual inspections with Primary Pro Bond / Seal ensures continued product performance.

Building regulations Part L states that all external pipework on an Air Source Heat Pump System must be fully insulated to reduce heat loss and maintain system efficiency.
In systems where every watt counts, Inta’s Pre insulated hoses have been designed for external use to prevent heat losses and to help maintain the COP and SCOP of the system, preventing losses of energy, contributing to an efficient system and preventing higher costs to run than expected.
The water resistant finish prevents the insulation from absorbing water and moisture that could result in an unintended outcome of the insulation becoming a conductor for heat loss.
It’s essential that all joints are bonded and sealed correctly to prevent any capillary traction occurring. The surface finish must be re-treated, the joints and seals inspected and resealed if necessary using Primary Pro Bond / Seal during an annual inspection to maintain the product performance.
