Gents I hope that you are both well :) I have been in touch with McCombi to arrange a full service, and he is going to get back to me when he can as he is very busy, however in the mean time I have another Vokera Excell 80SP question which I would like ask you. With the CH running normally, I...

Ian Many many thanks - you are a star :):)

Hi Ian I just wanted to say thank you once again - you were spot on about the pin on the flow switch. In the short term I applied some silicone lube to it and it is fine for now. I have been in touch with McCombi regarding getting a full service done. In the mean time I have another quick...

Ian you are a star :) :):) many thanks

Hi I am in Aberdeen

Hi Ianmcd I think that you could be spot on ! When I first switched on the boiler ( after changing the pump ) I do remember hearing the fan running on the slow speed, but I just had a listen now and I do not think that I can hear it. Would this be sorted as part of a full service ? Is there...

Hi I believe that need to have my Vokera Excel 80SP combi boiler serviced. It is providing plenty of hot water and the central heating is fine, it is just that after a period of not being used ( i.e. through the night ) it makes a brief loud mechanical notice whereupon the pressure gauge drops...

Hi DP I was wondering if you could help me ? I note that you are very experienced with Vokera boilers – I have a Vokera Excell 80SP. Q1. The boiler seems to be fine, however it does a couple of peculiar things which I was hoping that you would be able to explain :) I have recently noted...

Morning I was wondering if someone could help ? I have Myson Premier Compact Radiators to fit. I note that there are numbers stamped on the wings of the galvanised brackets. On the narrower wing is stamped “Type 11/21/22”, while on the other wider wing is stamped “Type 11 Only”. I have...

Hi I have a similar issue. I note that there are 2 vertical marks at the top and bottom of the isolation valves under my Vokera Excell 80SP boiler. Is it just a matter of backing off the phillips screw and turning the valve head through 90 degrees to close it ? I have heard that these isolation...

Many thanks - it's a pain when something is not black or white :)

Hi Endecotp What did you do in the end as regards your pressure testing ?

Dan thanks - the basic rule of PVT - pressure, volume and temperature. Any comments about how best to apply Loctite 55 to radiator tails ? Cheers

Evening I was wondering if any one can help. I wanted to carry out a wet pressure test using Loctite 55 to see how good it was. I took a brand new radiator - to each of the four outlets / inlets I fitted the following : 1. bleed off port 2. radiator tail with a stop end cap 3. radiator...

James - many many thanks - one very last question - when I said the lower half, sorry, I meant the first of the threads up to half way. I understand that the fitting on the radiator is 1/2" BSP, while the radiator tails are 1/2" Taper Thread. My logic for applying it to the first of the...

James - Many thanks - much appreciated. Did you find that the Loctite 55 was water tight on the first attempt ? Did you apply the Loctite 55 to the lower half of the radiator tail ? I am also confused as to how the radiator tail distorted as the end was free to rotate ?? I look forward to...

James many thanks - how many turns of Loctite 55 would you recommend ? Would 5 be sufficient ?

John many thanks

Hi Jeff - thanks - I appreciate that you can not see the tails, but from your experience should I replace these ?

Hi I was wondering if anyone could help ? I am in the process of fitting Danfoss RAS-C2 TRVs and lockshield valves to my Myson radiators. With the radiator removed from the wall, I cleaned out the 1/2" BSP tails on the radiators using a round wire brush. This allowed me to remove the old...
