boiler issues

[Guest wantthatone]

have a combi boiler, heating good but no hot water! any ideas peeps

[johnny g]

Exactly the same here. The mains feed outside has frozen. i.e. the feed to the house

I'm guessing you have a drip every now and again from a tap?

Outside? Hmmm... I think mine's underground. Will check!

if its a worcester 240 it could be the diverter valve has broken .if the boiler won't work at all the extraction fan may be gone.

Hold on, wouldn't it use the large water tank in the loft to feed the boiler, or is that already empty.

 

As above, I'd go with diverter valve, give it a tap.... (That said I'm no plumber and I have stuck a screwdriver into a hot water tank and then in a moment of stupidity, pulled it back out)

May not necessarily have a large water tank in the loft

 

I'd guess the supply is frozen too, had this in a few of our properties at work.

[Guest wantthatone]

is there a tank?

[Guest wantthatone]

oops! delayed again, shit!

Its actually my boiler guys. I dont think the feeds frozen as the cold taps are working okay and all water to the house comes in in one big blue pipe. There is no water tank in the loft, and the vaillant boiler heats hot water as the taps are turned on. The hots taps aren't even giving a drip at the moment.

 

It maybe the diverter valve as someone suggested, but ive no idea what this looks like!

As you say, could be the diverter then if you have cold taps running okay. IIRC it's like a diaphragm which moves when your hot taps are turned on...it's not that uncommon for it to wear out so while it may move, it's not getting quite far enough or with the necessary pressure to engage the hot water?

 

I'm sure an engineer-type person will be along to help soon. I employ contractors to deal with things for me I'm afraid

[2soops]

Id gladly employ someone myself but didnt have chance to phone around today and i suspect most plumbers would charge an arm and a leg in this weather

[JustGav]

Does your hot water have an electric element as well? If so, given the weather and the fact you have heating, don't mess with it till you get a qualified guy out... you might end up without heating and that is probably worse (or is that just my luck? )

You get me all wrong, sir. I don't pay for them, I work for a Housing Association

Mine does the same thing occasionally, a swift tap of the diverter valve with the handle of a screwdriver(while you have a hot tap open) normally sorts it, have a look on the net for your model of boiler and you should find some pictures of parts inside the boiler.

Can we add my house to your association temporarily, then you can send someone round with a big bag of spanners

I have thought about that but dont fancy ending up with no heating as well as water, tempting though

Combi will be off the mains.

Where is the boiler located?

[2soops]

Shes sat on the wall in the kitchen

If your heating works get that on for a while and maybe a hair dryer underneath it.

Alot of customers have been having issues with some overflow thing freezing. I'm not a boiler engineer so don't know the correct term.

[Soop Dogg]

This happened to my boiler a few weeks back.

 

The diverter valve may be known as a 3-way valve (radiators/water heating/by-pass) but this was ok. The fault was in the same area though - the diverter/3-way valve actuator which is an electronic device that operates the mechanical valve. Could be worth getting this checked out if you get someone round too.

 

Hope you get it sorted!

[2soops]

The heatings been on for two months now (missus is always cold even though she's in short sleeves still) so id be suprised if its frozen indoors. Do you mean the overflow that goes outside freezing, that may be possible

[j_jza80]

Combi boilers don't have external tanks of any kind, and don't have electric heaters in them. I'd guess the diverter valve (should be located within the boiler casing) is faulty, or if there's a flow of water from the overflow, the safety relief valve will probably be faulty.

 

Could also be a PCB board, but I would think this unlikely.
