Seasonal efficiency at the expense of more complexity - total waste of time IMHO. Anyway the customer (referal from John Brooks!) reported intermittent and then no DHW from boiler. The boiler is in a new build (3 years old).

On inspection the property was built by a roque developer (owner fully aware) and many building regs. Have been contravened eg the staircase. There are no TRV's, no room stat, the boiler timeclock was not wired in.

W'head caps on all valves, all rad valves cheap and nasty and pipes jammed in the skirting, no air vent on towell rail etc. No sleeve sealing. Fused spurs directly below boiler (the boiler drainoff is inacessible presure switch blocks it!). There was no proper flashing on the vertical flue through the flat roof. Water had leaked from roof and penetrated the boiler. The DHW thermister pins and connector had corroded so replaced.

The Range Linea 24 Linea 28. 2.3.5 An overrun is incorporated in the boiler in both c/h & dhw modes. The fan overruns until the boiler water cools to approximately. 726 Linea 730 Linea 735 Linea 726. * plus flue terminal. Title: Vokera Linea_7_Series_Standard_Efficiency_Combi Boiler Manual.

The boiler all appeared to work although modulation was not perfect especially at the lower DHW temperature settings. The boiler modulates the burner down, burner then goes off and there is a significant delay before re-ignition and hence water temperature cycling - classic blocked plate heat ex. The primary flow and return temp. Across the plate appeared OK but I removed and descaled the plate anyway just to be sure and surpisingly all very clean.

The non return valve rattled but I think this is normal for these boilers - I assume it is fitted to prevent gravity heat loss (boiler has preheat function) back up to the primary heat exchanger.
