⚠️no hot water Y plan system⚠️
Customer called to say they had no hot water but their heating was working fine, they said they had an old back boiler so they were a little worried it would be, to which I managed to explain that its not a boiler fault if the heating is fine…
when i arrived i found a Y plan system with a honeywell twin channel programmer and cylinder stat so to help me understand and diagnose the fault i whipped out the Breakdown Bible…
