Balfour beatty - damaged my boiler????

[beatts]

Hi

We have just had our gas mains changed from steel to plastic, balfour beatty have been doing this work (without problems and pretty efficiently i'd say). Anyway they turned off our gas for the day, to connect to the new pipes, and after reconnection everything seemed ok.

Their registered gas fitter came and purged our sytem? then reset the boiler and off he went, all was well.

That was three days ago, and now we can't get hot water.

Our boiler is a baxi 105e (not instant) and is 2.5 years old.

The heating works fine but no hot water, could any problems have arisen from the gas mains work do you think??? Everything was working for a couple of days after he left so it may just be coincidence.

There are no flashing neons to indicate a fault, the neon above the tap symbol does not illuminate on either CH/HW or just HW.

After reading into it, I had a look at the microswitch on the front of the valve, when I manually activate this switch the 'tap neon' then illuminates and the burner ignites but still no hot water. I didnt see any movement from the pin at the front of the valve.


any ideas anyone????????

many thanks in advance

Pure coincidence your diaphragm has gone nothing to do with gas side

HI

carrying out gas work should not affect this.
open hot tap then activate micro switch manually then you should get hot water. if this works then the DHW diaphragm could be split or damaged.

 

[beatts]

yeah, as I thought.

thanks I thought it may be the diaphragm,


does anybody know of where I can get hold of one in the north east (pref Teesside)


cheers

PTS , HRP etc not a hard part to get should be instock at no more than 20 quid

 

[beatts]

great thanks,

on another note, my pump was pretty hot, should it be?

 

[namsag]

yep it has water at 80c going through it

 

[beatts]

also f.a.o LUNAT,

when i activate the microswitch, i dont get hot water but like I mentioned previously neon above tap comes on and burner ignites but NO hot water.

thanks

 

[beatts]

When the diaphragm is completely failed then if you activate the DHW switch the heat will just go into the rads!
