Mechanical, Hydronic and Process Heating Applications
For these applications, storage tanks are normally not required. Connect the water heaters and pumps
in accordance with the principles shown in the diagram below with the following in mind:
•
Install the water heaters according to Equa-flow® principles as shown in the diagrams on page 18.
•
A disconnection union must always be provided at the cold water inlet and hot water outlet on the
water heater to allow for disconnection of the water heater.
•
Each high point of the system should be fitted with an air bleed valve or automatic air eliminator.
•
On radiator or heating systems where thermostatic or zone valves will vary the water flow through
the load, a by-pass with a suitable control valve must be installed to control the system water flow
rate.
BY-PASS VALVES must be installed at the end of the system furthest from the water heater.
INSTALLLATION
Typical Installation two water heaters, two tanks
