That’s why we’ve introduced a level of standardisation to external heat pump pipe insulation systems. From pre-insulated flexi-pipes and rubber-lined clips, to levelling grinder heads and sealing rings for a seamless connection to the building - every detail has been designed to make installs cleaner, smarter and more reliable.

We understand how tough it can be working against the elements while trying to deliver a professional finish. That’s why our products are ready to use, easy to maintain, and designed to eradicate messy, improvised methods that cause issues down the line.

Our goal is simple: to give professionals and homeowners a product that makes every installation easier, smarter and longer-lasting.

External pipework on air source heat pumps (ASHP) can lose significant heat if it is not properly insulated. High-quality heat pump pipe insulation protects the system from weather, prevents heat loss and helps maintain COP and SCOP performance.

Primary Pro provides a complete insulation solution designed specifically for external ASHP pipework, ensuring long-term durability and a professional finish.
