A prime example of controls not being explained properly
Its a vaillant system boiler, how can it not have vaillant controls?
Would very much appreciate a detailed explanation.
Thanks in advance

By Vaillant controls Alec means your programmer thermostat wiring centre etc
If you use their controls then the dials do as u are expecting
If third party controls are used the boiler is only told to fire not if it is for heating or hot water and is then diverted to whichever the controls are telling it.
I prefer to use vaillants own controls but this doesn't mean yours is wrong

A clock that u put times into for heating and hot water maybe in airing cupboard
OMG...
Alec - I thought you said your customers all loved the simplicity of this stuff Just kidding.
OP... The boiler is designed to have an inbuilt (or at least connected) controller that it can talk to. this has a sensor on your hot water tank that tells the controller how hot things are. The Tap knob on the boiler then has the ability to control the water temperature.
Your installer has (as Alec likes to put it) used numpty controls. I.e., simple. There is a thermostat on the side of the cylinder that controls the hot water temperature, and a clock that sets the times. the Tap dial on the boiler does nadda.
The radiator knob sets the boiler's running temperature, so you need to leave it at 70 - 80 degrees to get you water hot enough quick enough.
It is not worth loosing sleep over though.

Dan - thank you for your reply. I suppose it doesn't help matters that there is no clock. Anyway, the fact that it hasn't been setup properly, is this significant? Am i going to incur extra heating costs? Or be energy inefficient?
I.e. is it worth getting it fixed?
