One way to correct excessively long hydronic circuits.
One of the classic blunders of hydronic design is to create excessively long series piping circuits. Over the years, I've noticed that many new designers have a predisposition to connect devices like radiators, boilers, valves and piping into series circuits. There's something fundamentally appealing about making an “unbroken chain” out of such components. Unfortunately, this can quickly lead to problems with both thermal and hydraulic performance.
