Title was going to be "cold front warm rear" but sounds rude.
Anyway, I changed heat exchanger on Grant Combi 70 V3 as it was leaking . Fiddly, but all ok without leaks.
Now it's hot towards the back, cold at front. Flow from hot tap is lukewarm.
PV Schrader valve leaking too ... I thought pressure drop was due to leaking heat exchanger. Waiting for new one delivered.
Could there be airlock in heat exchanger? Shall I just wait until I replace PV then see if working?
Is there anything I need to do after a heat exchanger swap? I've got your PV depressurisation FAQ at the ready.
Thanks
