Thanks for all the replies and advice. I'm going to get the boiler serviced soon enough so will talk to the engineer about cycling and see if the boiler can be turned down any more. Will also get them to connect up the PRV. New shower is coming on a pace now, so shortly we'll know for sure...

Yes I've seen the instructions - the UK section on installation and filling is quite detailed, the Irish section is very vague... 3A.6.6 FILLING POINT A method for initial filling of the system and replacing water lost during servicing etc. has been provided. You should ensure this method of...

Thanks for the replies. Have just done a run with the stopwatch with it heating up a fairly cool tank load. I started the stopwatch when the boiler fired for the first time. On: 0:00 Off: 3:35 Burn: 3:35 On: 6:40 Off: 8:36 Burn: 1:56 On: 11:42 Off: 13:17 Burn: 1:35 On: 16:23 Off: 17:50...

Thanks vulcancontinental, There is only the one tank in the loft - the main cold water storage one. This has two 3/4" pipes from it - one feeds the bottom of the cylinder, the other the taps and the heating system (via a non return valve in the airing cupboard) I've never seen the pressure...

Sorry I'm not getting the point of bypassing the pressure switch - the pump runs without any problem whenever heat is being called for anyway.

Yep I couldn't find a manual online for it - although the vokera website has one for the 14e, which is essentially the same: http://vokera.co.uk/wp-content/uploads/2009/04/mynute_10e_14e_20e_installation_and_servicing_instructions.pdf I found the manuals for ours stuck to the back of the...

Just checked - def no pump speed switch on the pump :-(

Maybe I missed it - will open the lower cover later and check all round the pump power box for a switch. Could it be a lack of system pressure? The pressure always reads at zero - as its filled by gravity from the loft, as opposed to a mains pressure filling loop, I dont see how it can ever...

System is closed, so no expansion pipe - boiler has an expansion vessel in it. Good idea re turning down the pump, but the pump is integral to the boiler and I don't believe it has a speed control - least I've not found mention of it in the installation manual, and there is no obvious control...

Thanks for the reply spraggo, The system doesn't have an expansion tank - it fills via a non-return valve that tees off from the loft tank cold feed to the house taps....not sure it's supposed to be like this, but that's how it's connected. There is an automatic air release valve as you...

Hi All, We have a Vokera Mynute 16e boiler in an s-plan system to give independent control of the hot water and heating. When the system is calling for heat for the hot water cylinder only we find that the boiler cycles rapidly - 30 seconds burn, couple of minutes rest, over and over again...
