Inta HPHOSE500 2 Pack 500mm Pre Insulated Hoses 1" Female Swivel X 28mm

2 Pack 500mm Primary Pro pre-insulated hoses 1˝ female swivel x 28mm. 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.
