Hi, I have a 20yr+ old Vaillant Turbomax VUW 282 with a magaclean (on the flow side) and connected to Hive system for a 4 bed house.
Had it serviced by British Gas engineers - but its a mixed bunch that come around and often depends on the engineer quality.
Recently had its diverter valve replaced (2018), PCB replaced (2021) and Air Pressure switch cleaned and rebuilt (2021)
At the moment its working but something weird is happening when the hot water tap is opened...
1 Central heating demand indicator comes on
2 Fan operation indicator comes on
3 Ignition indicator comes on
4 Burner indicator comes on
5 Water gets very hot within seconds
6 Boiler shuts off with Burner indicator going off
7 Water gets slightly cooler
8 Start-up cycle happens again
9 Water gets warmer slower
10 Boiler remains on second start-up and continues to provide stable hot water
Same thing happens when the central heating is on and hot water tap is opened - it cuts out the boiler on hot water demand, and then comes back on again moments later and stays on.
This can't be good for the Boiler? Its old thing, but I hear they have some life in them if looked after.
Anyone any ideas what's going on??
