just to finish this one off... I've found the culprit or rather culprits... I took the front off the pump to get to the pump impeller and found it crudded up with sludge and all of this (see pic) . They're a little like crusty carbon pieces that catch n block up the veins and so reduced it's...

Thanks will take a look

Hurrah so its resolved! BG came and the engineer removed the pump... turns out the impeller was sludged up with a coating of crud. She cleaned it off reinstalled and it now runs sweet and like a dream... Full speed on all settings without any of the noise that I had before. Go figure...

So BG are gonna come out tomorrow... Had a frost last night so it was quite cold when I turned the heating on to monitor it.. it took about 30 minutes before all the rads were feeling some heat. about 50 mins before they were all hot. Any idea how long it should take to heat to this point...

Hey thanks for that detailed info, yes it defo looks as though the current flow is weirdly on the zero..:unsure: so strange.. I've turned it off for now and will see what BG say first thing in the morning. They came out pretty quick last time.... will post back when I get further along..(y)

Thanks... i'll probs ring em on Monday, but what confusing me is the rads still heat up ok, if a valve was left closed would the rads heat up? NB hot water also heating fine

Hoping someone might have an answer here.... Moved into the house last year so don't have any installation service/history... I had an additional rad fitted about 8-9 months ago the pump ran at 45W (way too noisy) when on III and 19W (Quiet) when on II. Just recently British Gas came out to...

lol....:LOL: the battery that's shown to fit the Excel (on the website I looked at) shows a different battery type with a different amp rating so I figured that the electric specs might have been different for the Excel despite the casing being the same... Will check out the bell box too...

OK Thanks for all the help folks... You've been amazingly helpful (y)(y)(y)(y)(y) I've learnt such a great deal. Am gonna take another look at the panel tomorrow just to make sure there are only four zones wired and if so I might well look at getting a panel upgrade (Excel) as all the...

Thanks for the info... wonder if I can get another model that uses a similar PCB... The EXCEL looks like it might be similar and would give me an LCD on the small panel. That way I could almost refit the wiring like for like if the board is similar. Any suggests on this?

Thanks 'The Pars' fuse is ok... Could it be the transformer unit? or defo the panel? I see the transformer units are available and look an easy replacement.

I cant seem to get an event log to show... :confused: So the power (and tamper) thing is still a mystery The battery is fully charged - The battery fuse is good - but it just doesn't run from the battery :cool: So next question is the voltage on the battery leads (3 to 4 volts enough? Just...

Ok so the voltage on the battery leads varies between 3 & 4 volts... would that be what you'd expect?

Hmmm:confused: curiouser and curiouser...:cool: firstly I appreciate all the previous comments.. thanks (y) So.... I Disconnected the power supply and expected the panel to stay on from the new battery... but it didn't o_O So the battery still isn't powering the panel when the powers off...

Thanks secureiam will take a look at that tomorrow (y)
