central heating vaillant boiler

aggi

Hello all. I have moved to new home and all of the things are wrong, now even heating is gone. 
So the boiler is not combi. it is couple years old vaillant boiler. did work in the morning, then fuse for cental heating has popped. We have switched it back on. Now the boiler control panel seems to be fine, the thermostat keeps clicking ( asking for heat). then boiler sounds like it fires up for 30 sec and then off again. 

any idea? is there any pumps etc that could have burned when fuse has gone?

also , sorry for stupid question but how does this work?

I think your best bet is call out a heating engineer and ask them to investigate your problem, give you a price to fix it AND explain how your heating system works. It is information that is worth paying for.

Vaillants (at least you got the spelling right, rare on here) normally have a useful error code when they go wrong easily googleable.  
That looks like a pressurised cylinder but I'm a random internet person. You possibly have a system boiler with pressurised cylinder (google megaflo), if your hot water comes out at decent mains pressure the same as cold from all your taps then that's what this setup is.

Do you have something like a Honeywell motorised valve. Google to see what it looks like. They can be problematic so I found out. They get stuck and burn out. It's an easy and cheap job to replace if that's what it is.

It could be anything, it will all want checking.

That looks like its just a shower pump, And the red thing is the heating pump.

It blew the 3A Fuse in the airing cupboard, in a spur box somewhere on the left in that picture?
Can you get the error code from the boiler, and the model.

Thank you for all replies, that cylinder is still producing hot water and the switches on left were off when we moved in, so guessing the fuses burnt or not will not affect the issue ( ?). I do have honeywell thermostat, and boiler is ecotech plus 418, and no faults are displayed, only egg timer keeps coming on which prevents boiler from trying on all the time. 
the water pressure upstairs is almost non existent.

I think I will call  some one on Monday and ask for visit.

The switches on left that were off may be for the electric immersion heater, you don't want to leave that on 24/7, 1hr in the morn and 1hr in the evening will do for hot water.

Trace the wire from the top of the tank to the switch.

Its a vented system. Best get a heating engineer if you haven't been able to resolve the problem.
