Hi all and thanks for reading..My problem with the Vaillant Turbomax 824E is that i have to reset the boiler (ie turning off) before i can get radiators to warm up...if then i use the tap(s) to demand hot water sometimes i get it and sometimes i dont and sometimes if i do then the radiators go cold when i cease demand..sometimes when i turn on hot taps i get no hot water unless again i reset and try again....Any help greatly appreciated...the boiler is 10 years old but want it to last through this winter before i can afford to buy another..

Sounds like a fulty diverter valve.

Look in the FAQ where I posted an explanation of how to diagnose that.
