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.Pre-insulated to reduce system heat loss preserving system efficiencyAvailable with 1? female x 28mm or 1 1/4? Female x 35mm connectionsSupplied in pairs to suit the flow and return of your heat pumpDesigned to connect directly to the heat pumpAvailable with a straight or bent heat pump connection to suit a variety of units and installationsAdditional piece of insulation provided to insulate the connectionsFull range of ASHP control valves including magnetic filters, antifreeze valves, balancing valves etc availableThe Primary Pro insulation is water and UV resistant making it suitable for all weather conditions.
