Low Loss Header Vs Close Coupled Tees

Traditionally Close Coupled Tees (CCT’s) have be used in the Commercial Heating sector, they do work very well, But there is now a new trend of fitting low loss headers (LLH’s) instead of CCT’s.

Let’s have a look at some facts about these Low Loss Headers, Close Coupled Tees and also Buffer Tanks:

Any component, or combination of components, that has very low head loss, and is common to two or more hydronic circuits, can provide hydraulic separation between those circuits.

A LLH reduces the flow velocity, in the vessel, which allows for two secondary functions, air and dirt removal in one device. 3-in-1 hydraulic separators (LLH) make air removal and dirt removal primary functions, along with hydraulic separation, with no added piping connections or installation costs. Magnetic dirt removal adds a fourth function to the above. Magnetic separation is especially effective for older system retrofits which can contain a high amount of magnetic iron and steel particles.

LLH’s tend to make a neater and more compact job of the pipework.

CCT’s are easier to insulate and cheaper to buy, but they don’t necessarily save installation labor compared to hydraulic separators.

A system with CCT’s still requires air and dirt removal devices and may require more wall space.

Locating a Buffer Tank (Thermal Storage Tank) between primary and secondary piping offers the added advantage of hydraulic separation, in addition to having a buffer, Separate air and dirt removal devices are still required.
