Discuss Bypass Valve on S-Plan Installation CH system in the USA area at PlumbersForums.net
Ok. I will check. ThanksDepends on boiler manufacturers instructions.
There is no explicit mention of bypass exclusion. There is an arrow on the pump that indicates flow from right to left from the boiler. But that boiler connection at the rear of the boiler that the pump is connected to is described as the Heating Return which would suggest the opposite flow. Confusing. So there doesn't appear to be a bypass valve. I'm guessing that the gate between the white Reliance valve and the HW tank is just an isolator.Depends on boiler manufacturers instructions.
It does have pump overrun.If it has pump overrun yes should have an auto bypass
