There must have been some way to control the hot water temp. There could be a Cytrol valve on the return from the cylinder.These are adjustable but are likely to leak after adjustment.

Check to see if the thermostat on the hot water cylinder is set at 60deg.If its not,set it to that temp.If that dose not work then you need a new cylinder stat.

The instructions that came with the Pump where not that good,mostly pictures.I took it that this pump adjusted its self to run as economically as possible depending on the varying demands of the system(trvs opening and closeing)so it would need to vary its speed or pulse

Fitted ups2 6 months ago,no problems at all.I expected it to pulse but it runs smoothly,pushes the water around 12 rads on setting 1.I don't have a sealed system

Why did I not think of that :?: O.K. read through the instructions again,on page 28 (specifications) it shows the smoke detector dose not emit any sound(no dBA).So if the C.U. siren is turned off you must be able to hear the outside siren,not easy if you sleep on the opposite side of the...

Hi,just fitted a smoke detector to my 5 year old 6400 alarm.Instructions not very good.When alarm is set off by pir or door contacts dose the smoke detectors built in siren sound as well.I am asking because I did not want to test it and have the alarm phone out.(c.u.siren set to on) Regards Bill.

The fan on this boiler has always run all the time.Now fan switches off when hot tap opened or central heating calling for heat.Flames visible through site glass then boiler shuts down.Any ideas please

Hi,thank you all for your comments.I think the words upside down are causing the confusion.The grundfos instructions on page 5 show the arrow on the pump body pointing upwards with a water flow symbol pointing upwards next to it.I took this to mean that the pump should only be used to pump...

Hi,No auto bypass.Potterton kingfisher 2 boiler,gravity H/W,Cytrol valve,Pumped heating.

Hi,old pump working O.K.Thought I would change it in the summer rather than winter.( I got the new pump cheap) will also have a working spare.

Hi all,Thanks for your speedy replys.But the question still is will the UPS2 work upside down,vertical on the return to the boiler.

Hi all,After looking on the grundfos web site for a replacement for my 15/60 pump I purchased a UPS2,it told me it was a direct replacement.I could use the old body and just change the motor.Looking at the instructions (page 5) it shoes the pump in a vertical position pumping upwards,i need it...

hi all, Its my second boiler in 40years.The first was a potterton c55/16,the current one is a potterton kingfisher 2,gravity hot water,pumped heating.The pump was a grundfos super 4-50 single speed.When I tried to adjust the variable adjustment arm it started to leak,so after 40years I fitted a...
