[b]Boiler:[/b] Alpha Ocean eco240
When a tap/shower is turned on the Central Heating comes on [b][color=red]RED HOT[/color][/b]. Even though all the central heating controls indicate that the CH is not on. When the tap/shower is off the CH goes off.
ie. No light is on (only water), manual switch (inside timer) is set to '0' or 'auto'.
The CH is supposed to turn [b]off[/b] when the any water is run, but i get normal temperature water and red hot heating
Any ideas anyone, i have never had a problem with this boiler since installation in 1996. Please do not diss this boiler as many engineers do not like them.
