Heat Pump Insulated Hoses

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, our 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 efficiency. Available with 1" female x 28mm or 1.1/4" Female x 35mm connections. 

Supplied in pairs to suit the flow and return of your heat pump. Designed to connect directly to the heat pump. Available with a straight or bent heat pump connection to suit a variety of units and installations. Additional piece of insulation provided to insulate the connections. Full range of ASHP control valves including magnetic filters, antifreeze valves, balancing valves etc available. The Primary Pro insulation is water and UV resistant making it suitable for all weather conditions. Must be inspected annually and retreated, with joints resealed if necessary using Primary Pro Bond and Seal
