Reduced pipe sizes
Increasing the ∆T across the system results in lower flow rates and hence smaller pipework.
Small bore terminal unit pipes
The internal diameter of the smallest traditional copper pipework is still too large for efficient performance of ultra-low flow systems. The solution is to make use of micro-bore, flexible metal piping such as AluFlex. This can be supplied pre-insulated, which makes it a very cost-effective solution.
AluFlex is ideal for lower flow rates:
There are also a number of other benefits of AluFlex pipe systems for district heating networks:
- Reduced pressure drop due to avoidance of angled bends
- Reduced installation times
- Available with mechanical compression or pressfit connections
- Resistant to rough handling
- Rated for temperatures up to 95ºC and a working pressure of 12 bar
- Life expectancy of 50 years, full guarantee for 10
- Contains a gas tight boundary.
SAV have put together a CIBSE-accredited CPD Seminar, which explores the main issues arising from a 70/40 approach to design. The agenda for this is given under the CPD Seminars tab further along this website. The 70/40 method can be expected to have far-reaching implications, and discussions which are a normal part of each Seminar will sharpen your insight into developments in this field.
If you would like to explore the potential offered by the 70/40 method to any building services project, please feel free to provide some information via the Contact Us page, or by phone / e-mail. We would then assess how best to develop the ideas further, either by CPD Seminar, round table discussion, site visit or other communication.
We look forward to hearing from you.
