Hi all.
1)If the heat leak of a CH system is provided by a rad in the bathroom fitted with 2 lockshield valves so that you can not shut it inadvertently, would you still need to fit an automatic by pass valve to your combi if it does not come with it?.......or you only need to have one or the other??
2)When you close the hot water tap, would the pump over run of a combi push the secondary circuit hot water towards the heat leak rad or elsewhere within the combi case?? Thank u 4 your time.
