random flushing of heating system
I actually started a new job,
They have alot of sediment/scale (what be it) in the heating system.
They insist on blowing down their Y strainers, ( and anything else with a blowdown valve) unit water runs clear.
I told them they are introducing un-needed fresh water into their heating system, which is in turn creating more sediment/scale.
The boiler plant is 12 Aerco boilers, a mix of steel pipe and copper.
Many heat pumps, which the y strainers plug up often, and require more blowing down.
I suggested some water treatment.
Any help is appreciated
