Central Heating / Water Help Please

[theshrew]

Ive got a problem with my Central Heating system.

I cant switch the hot water on without the central heating system being on. The only way to stop it is to turn the radiators off. The one in the bathroom cant be turned off i presume this is a safety feature.

Anyone got any ideas why this could be ?

do you mean when only your hw is on your rads still get hot ?

 

[theshrew]

Well sort of.

On the controll pannel i have to puttons one for the HW one for CH

When i press the HW one it doesnt kick in the boiler or anything and we dont get hot water.

If i press the CH that works fine. And we get hot water even if the HW isnt shown as being on.

To me it sounds like its wired up wrong ? I would have thought you could have one with out the other ?

what boiler and type of system do you have ?

 

[gas4you]

What system/boiler do you have? A combi or a standard boiler and hot water cylinder with zone valves?

You haven't given us enough info to go on.

 

[theshrew]

Not sure what make the boiler is off the top of my head. Will check when i get in from work.

Not sure the name of it but its not a Combi system

take it then you have a copper cylinder, tanks in the loft etc

 

[theshrew]

Yes tank in the loft and one in a cuobard upstairs

 

[seco services]

have you got one of these in the airing cupboard ?

or two of these

 

[theshrew]

One above the boiler yes. Not noticed one anywhere else

 

[seco services]

what one top or bottom ?

 

[theshrew]

Im pretty sure its the top pick mate

Take it they are some kind of switch to divert the water to the CH or HW ?

 

[seco services]

has it always been like it or just started ?

 

[theshrew]

Not lived in the house long its always been like that
