As the industry shifts from refrigerants to water-based systems for energy distribution, the demand for cost-effective, durable, and efficient solutions is growing. With rising copper prices, increasing concerns about corrosion, and the need for faster installations, our Multitubo pipework emerges as a superior alternative—offering reliability, ease of installation, and long-term performance:
- Gas, Diesel or Pellet Boilers
- Air-to-Water and Ground-Source Heat Pumps
- Hydronic Underfloor Heating Systems
- Radiators
- Fan Coil Units and Chilled Beams
- Potable Water Applications
Concerns about adopting new technology, especially when used within boiler systems, are understandable. However, Multitubo delivers a durable and dependable solution for commercial heating and cooling networks, with a continuous operating temperature range of 20°C to 80°C (short-term up to 100°C) and a pressure rating of 10 bar. Multitubo provides a durable and reliable solution for commercial heating and cooling networks. Manufactured to the ISO21003 standard, all components undergo rigorous quality assurance testing to ensure long-term performance. Our Multitubo systems are backed by a 25-year warranty and have a service life of 40–50 years under typical operating conditions.
Multitubo Composite Pipe: A Proven Technology
Multilayer composite pipes (MLCP) were first developed in Finland in the early 1990s and quickly revolutionised the European plumbing market. By combining polyethylene raised temperature (PE-RT) with an aluminium core, it combines the flexibility of plastic with the strength and durability of aluminium. These pipes offer a lightweight, corrosion-resistant solution for plumbing, heating, and mechanical services making them the logical solution when designing the heating and cooling system in our new building. In an addition to the pipework for our heating and cooling system, Multitubo pipework has also been used for our new working products room and training centre delivering water to our full range of appliances including our commercial gas boilers.
Since being introduced to New Zealand in the early 2000s, our BRANZ Appraised (740) Multitubo pipework has become a leading pipe system in the NZ market. Distributed by Central Heating New Zealand, widely used in residential central heating systems, its versatility and range of available dimensions have led to increasing adoption in commercial plumbing and mechanical applications.
An Alternative to Copper Without Compromise
While copper remains a well-established choice for commercial plumbing and mechanical services, Multitubo PERT-AL-PERT pipework presents a compelling alternative. Offering faster installation, reduced costs, corrosion resistance, and compatibility with modern chilled water and low-temperature heating systems, it is an increasingly preferred solution for contractors and engineers looking to optimise project efficiency.
By adopting press fittings for sizes up to 50mm and fusion welding for larger diameters, Multitubo pipework provides a seamless and adaptable installation method without the constraints of traditional copper systems. Whether for heating, chilled water, or potable plumbing, this MLCP technology continues to prove its value across commercial applications in New Zealand and beyond.
Key Benefits of Multitubo PERT-AL-PERT Pipework
- Faster Installation & Lower Costs
Press fittings (up to 40mm OD) eliminate soldering, reducing labour and site disruption. Fusion welding (>50mm OD) ensures strong joints while being faster than copper welding or brazing, cutting costs on large projects. - Corrosion Resistance & Longevity
Unlike copper, Multitubo resists chemical degradation. Its aluminium layer prevents oxygen ingress, making it ideal for LTHW systems using boilers and heat pumps. - Flexible & Easy to Install
Pipes (≤40mm) can be hand-bent or shaped with tools, reducing fittings, and improving hydraulic efficiency. - Pre-Insulated for Efficiency
pre-insulated coils minimize heat loss in hot water systems and prevent condensation in chilled water lines, further cutting installation time. - Lower Material Costs
PERT-AL-PERT is more cost-stable than copper, offering a budget-friendly solution for commercial installations.
