Thanks Poxi. Just re-posted in CC

Recently did a LLGS at a property with said boiler. All ok on gas check and results as expected. All nice and as per the book. Tenants neighbour collared me on way out and told me that boiler sometimes makes noises like a chugging train. No common thread times of day etc. whilst I was there I...

If its an existing property and not new build why worrying about building regs?

No real answer to this as we all have our own preferences. Personally would choose Vaillant over Worcester all day long. However if it was for my own house then would opt for Viessmann.

Also make sure you get either a battery or mains operated unit and not one of those stick on patches that change colour! Also need to bear in mind that some units have an expiry date (sensors don't always last forever and may need changing after 2 years)

If you've recently moved into the property wasn't a HETAS Certificate mentioned in the survey? Sounds like you need to employ the services of a HETAS registered engineer who will come and check the installation. If everything is ok and in order the the engineer can them issue report stating all...

Thanks spraggo Do you know what an equivalent of the BG badges pump is?? CP53 is what parts centre advised! Thanks

Went to a Potterton Promax 24HE heat only boiler yesterday where owner had reported "loud noises" and boiler lock outs. Anyway tracked noises down to the pump. Isolated and removed pump head only and sure enough several cracks on vanes and bits missing. The old pump head was badged as BG Multi...

Any idea what my chances are if I go with the idea of up front honesty and request permission?? Along the same lines do I also need permission to build a shed or greenhouse? not that I plan to, but just trying to understand the justification... dont you just love red tape!!

Should be straight forward enough unless something untoward has/is happening. Try looking at this video on you tube and try again. Failing that call someone out! http://www.youtube.com/watch?v=1Ea7czrQmsY

depends on number of factures. Needs correct pipe sizing calculations doing to ensure sufficient flow of gas to appliances. To answer your question all installs are different so no definitive answer unless viewed and calculated.

Have seen similar Vaillant combis with only one valve for filling. Sounds possible that the first time you opened and heard water, this way actually filling system up. Along the same line of thought if that pressure gauge was faulty you didnt hear anything the second time as system full or at...

Got a nice big tree in garden not overlooking any neighbours and have started building a small tree house for kids, only to hear nasty story about someone getting visit from local council saying permission was needed to continue his tree house! Have already put floor and 2 sides up and now bit...

Got a Linea 28 with no hot water. CH all OK. Thing is I get no water at the hot tap! Checked pipework and no freezes. Boiler fitted to 1st floor. When hot tap in kitchen downstairs trned on, get slight trickle then stops! If I turn the hot off, wait 10 mins and turn on again, same small trickle...

Yep, tried both and BBU still didnt fire up! Checked hot water tank hour or so later after I'd relayed some of the laminate flooring and water was hot again. Could the tank be heating the hot water on its own? Had looked everywhere when looking for the pump and didnt come across any zone valves...

Tried suggestions today Glasgowgas Located pump - all working OK Ran off hotwater until tank cold Turned on demand for hot water via controller BBU still failed to fire up! Any ideas? Could it be a component of the multi function gas valve (solenoid?) not sure how to test Thanks...

Thanks for your patience glasgowgas. Decided that I'm going back tomorrow to see if I can resolve. Does it sound reasonable that the 1 pipe I cant see much of as it goes down under the floor (the one from the bottom of the BBU) is the one with the pump on? anything else worth checking whilst I'm...

Cheers for the quick response glasgowgas. If I can hear the pump do I still need to expose to check it? Also would the pump stop the bbu comin upto full flame?oh and one last thing! All but one pipe from the bbu go up to the 1st floor to the tank, the other goes down under the floor. Have...
