What is the Best Material for Air Source Heat Pump Connecting Pipe?

When choosing the material of the air source heat pump connecting pipe, it is recommended to use aluminum-plastic pipe or PB pipe.

1. Aluminum-plastic pipe

Aluminum-plastic pipe is a composite pipe composed of aluminum layer and plastic layer. It has good corrosion resistance, high temperature resistance and long service life (up to 50 years), and is easy to install and not easy to rust. In addition, aluminum-plastic pipe also has good thermal insulation performance and pressure resistance, and is currently an ideal material for household heating pipes.

2. PB pipe

PB pipe (polybutylene) is known as "plastic gold". It has extremely high temperature resistance, pressure resistance and chemical stability. It is suitable for a temperature range of -30℃ to 100℃ and has a service life of up to 50-100 years. PB pipe is light in weight, flexible, non-toxic and odorless, environmentally friendly and safe. However, the price of PB pipe is higher, but its excellent performance makes it a high-end choice.

Comprehensive consideration, when installing an air source heat pump, PB pipe is the best choice if the budget allows. If your budget is limited, aluminum-plastic pipes are a cost-effective alternative.
