Manifold system versus hot return system
I like the look of a manifold type water system, however I have some reasonable long runs for the hot water.
Is there a way of calculating how long it will take hot water to reach the tap from a cylinder.
I will have a measure up today to see what you all think
I understand you can change pipe size to certain things.
But it would like to be able to do a mock up to see if it will work before I dismiss a manifold and start thinking about hot returns.
@Russdl That’s not a cast body - it’s a resin body by the looks of it so I would query the model number on the front as a resin body pump is suitable for potable water instead of a bronze body (and Wilo confirm this)
And Hep2O can be used as a hot water return circuit. You have (incorrectly) read the guidance and don’t understand the BS/ EN definitions and I have had this confirmed by Wavin.
For info the below is the definition they (Wavin) use for a hot water return circuit whi
