Principles
The principle of Equa-Flow
®
is to ensure the demand on each water heater, or storage cylinder in the
bank is the same as any other. To achieve this, the following is necessary:
1.
The
cold
water manifold (cold header assembly) must be designed to balance the flow to each
storage tank i.e. each branch line must be the same diameter and length and be fitted with
identical ball or gate valves (refer to diagram below).

2.
The
heating
water manifold (primary return header assembly) must be designed to balance the
flow from each water heater and/or storage tank i.e. each branch line must be the same diameter
and length and be fitted with identical ball or gate valves (refer to diagram below). Water must exit
from the opposite end to which it enters the manifold.
