Can a low loss header be fitted horizontally?
Thou shalt avoid horizontal headers Horizontal Low loss headers are just as they sound. A low loss header turned on its side. They are great for saving room and often come with commercial boiler installation packs. However, it lacks the ability to separate air and dirt as efficiently.
When should I use a low loss header?
You would likely need a low loss header if you have a very large home or business premises and you’re using a low water content boiler. Your low loss header will need to be sized correctly depending on the flow rate of water around the building.
Can you oversize a low loss header?
Low loss headers are sized in cubic metres per hour. NB: It is better to oversize your low less header than undersize. There is a rule of thumb for sizing low loss headers based on the principles that: The higher the output of the boiler, the larger the header diameter and longer the header needed.
Why use close coupled tees?
Closely spaced tees are easier to insulate and cheaper to buy (can’t argue with that) but they don’t necessarily save installation labor compared to hydraulic separators. A system with closely spaced tees still requires air and dirt removal devices.
What is a distribution header?
A fluid distribution header is characterized by an inlet on one end, a drain on the other end, with multiple outlets on the sides. Typical fluid distribution headers are manufactured from a piece of pipe or bar and feature welded or threaded end connections.
When would you use a hydraulic separator?
The Hydraulic Separator is multi-purpose equipment that replaces several components in the system, simplifying piping and reducing installation time. BENEFITS, FEATURES AND FUNCTIONS: Hydraulically separates primary and secondary circuits. Separates and vents air from the system.
How do you pipe a low loss header?
We recommend installing your low loss header vertically as – at this orientation – they can help collect sludge from the system. Due to the low flow velocity through the low loss header, the debris from the system has time to fall to the bottom of the header and is trapped for safe removal via a drain valve.
What is the function of header in boiler?
A header transfers a heat transfer medium (water, steam, oil, etc.), typically via pipe(s), between (one or more) boilers and (one or more) points where the heat is required. A header can connect a single boiler to a single point where heat is needed.
What does a boiler shunt pump do?
The boiler shunt pump circulates the water from the flow pipe into the return pipe or directly into the boiler.
What is hydronic separation?
What is a CCT heating?
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.
What is instrument air header?
Air Header is a series of multiple valve assemblies that operate from one originating point. air header manufacturers in India designed these valves in a way that they can accommodate various valves. The inlet connection of the valve has multiple outlet connections.
