Hot Water - Low Flow Rate

Avro_Driver

I have a Saunier Duval F30e which seems to be working fine. Cold water inlet pressure is 1 Bar and both domestic hot water and central heating is working as advertised.

Cold water is coming through in a healthy flow but as soon as a hot water tap is used, the flow is there but only at only fraction of the cold water. It's could be best described as an 'enhanced' trickle.

Any ideas as to what could be causing the poor delivery of hot water?

Thanks

Hi.

Inlet filter blocking or plate heat exchanger blocking.

I think you are refering to the sealed system pressure of 1 bar not the cold water mains pressure, which should be higher than that.
