Hi,
Just installed U/F heating in my extension so put S plan in with 2 valves on the return.
When the valves close the boiler carries on for a little while (orange connected to boiler heat demand).
The manual says 'The boiler utilises the primary side of the DHW plate heat exchanger as an automatic integral bypass' but to my ears it sounds pressured when the valves close.
Is it worth fitting an external bypass to be on the safe side or let the internals deal with it?
Thanks.
