Many thanks to everyone - very much appreciated :)

Hi Madrab Thanks. I was worried about doing that test as I had read that the Vokera isolating valves have a tendency to leak once they are rotated ? Have you found that they leaked once activated in your experience ?

Hi there I have a question that I would like to ask you both. I have a Vokera 80SP Excel combi boiler. Over the course of 24 hours with the CH off and no use of the HW, the pressure drops around 0.5 Bar ( 1.2 Bar to 0.7 Bar ). The system has recently been topped up with 1L of corrosion...

Hi I have typical radiators in my house. Whoever fitted the radiators mangled the compression nuts on all of the connections between the lockshields / trvs to the copper pipe. It looks as if they were tightened up using a set of badly fitting mole grips ?? When decorating I decided to replace...

Many thanks to everyone - my suspicion was an internal fault in the meter which created a short and tripped the RCD.

Thanks flameport, but I double checked that it was set to the 250V ac setting before I started to use it.

Hi thanks for your reply. The meter looked very similar to this picture. No I never use the meter to measure amps.

No I should have said that I also checked that, however I was under the impression when measuring ac that it did not matter, however as I say the black lead went to "-" and the red lead went to "+".

Hi I wanted to measure the mains voltage via the power lead that runs to my kettle. I set the meter to the 250V ac range. I inserted the black probe all the way into the Earth terminal so that no bare metal on the probe tip was visible, so as to be safe. When I inserted the red probe into...

Many thanks - much appreciated :):):)

Hi I need to have an Danfoss ATP Pipe Thermostat installed in my CH system. I can not find the installation instructions online. What I was wondering will this stat need 3 core ( 2 core plus earth ) or 2 core cable. I can not tell if is double insulated. As to the cable size I was planning on...

Thanks Oilhead ..... I guess that says it all :)

Hi Oilhead Many thanks for your reply. The boiler was installed in 2006 - it is a system boiler. The leak ( which is crystal clear water ) is appearing right at the bottom and is weeping forward in the bottom of the actual casing. I think that all the obvious potential leak points have been...

Hi can you possibly help ? :)

Hi there I was wondering if you could help me ? I have read your comments about corrosion inside oil fired condensing boilers when the return temperature is low. I have a Grant Vortex System Boiler 15/26kW and I think that the leak that I have, below the boiler, could possibly be due to...

Ianmcd - many thanks once again - assuming there is no hole in the disc might it still be worn and best changed ? Would you also recommend changing the spring as well ?

Hi Ianmcd I wanted to say many thanks for your help with my Vokera Excel 80SP boiler. I have another question which I would like to ask you. I had the boiler fully serviced the other day - At the same time the diverter was fully serviced using the T0019 service kit. However I am still finding...

Hi Jamie I was wondering if you would be able to help me with my Vokera boiler in Aberdeen. I sourced all the parts that you asked for. If you can not help I would appreciate it if you could please let me know. Thanks Ken 07720 882809.

ianmcd - many thanks - much appreciated.

Hi many thanks for your reply. I am having a problem in that the CH will not run at the high temperature - as a result the radiators are only warm to the touch, rather than hot. Sometimes they are hot, but not often. It just so happens that I found that the CH control knob was super sensitive...
