Hello everybody.
I am just about to install an unvented cylinder. 2 heating zones, one hot water zone. It's an S-Plan system, with an auto bypass.
I remember reading about a rule of thumb when connecting my returns back to the boiler, but can't quite remember exactly what it was talking about and why.
I think you need to connect Heating return, hot water coil return then bypass, then filter, then boiler. Is that the right order?
I think the idea is to make sure your rads are not heating up in summer when you've only running DHW coil.
Can anyone let me know what the best order is and if there's a rule to remember please?
