Hi, can any one with trade experience tell me if i mix coloured trade vinyl matt with a little super matt (say 25/30%) white. A) will i have problems the with the paint? B) will the matt sheen still be relatively tough - ie for wiping etc ? The reason is we want to lighten the colour a...

Thanks fellas, This post is a year and a half old now. Ended up replacing pump with manufacturers part at customers expense, couldn't deal with going back again if things didn't work out. You try and save money for customers and it ends up costing you your time and money and then if...

Thanks Muggles, The pump heads are identical and the only differnce is the halstead one doesn't have the speed adjustment on the side. £72 inclusive from local guy and save bother of delivery. Might order the original as a stand by so its on the way if this doesn't work and I can cancel...

Nobody got an opinion on this subject? :cry:

Hi All, I need to change a pump in a halstead ace high/(wickes) 102 combi boiler. Does anyone know if I can get a compatible pump or even just the head rather than pay £148 for a halstead branded grundfos pump. It seems crazy that i can get a standard UPS 15-60 130 grundfos pump for...

The pump appears to be free and turning ok when I take off the cover screw.

Hi Mandate, That link seems to be broken and bethere.co.uk only takes me as far as a broadband supplier. Thanks anyway, Jon.

I agree, the boiler only fires for a about 2 seconds on heating and then fails - no sound of pump starting just fan and burner, no movement of primary flow pin (it stays in). Hot water has a little movement on pin but doesn't quite make the flow switch and so no pump no fan/ burner. Many...

Hi Tony, Thanks for your response. I did the link from conbustion chamber a week or so ago but haven't heard anything back - will do it as you have suggested though! I eliminated the thermistors as they read 18 k at very cold which apparently is within specs, the pump is getting 230 when...

I am, I was hoping you guys might be able to help a little. Being an Aussie in UK I'm still trying to get my head around all of the boilers over here and am struggling a bit on occasion and don't want to fork out for wrong parts because of wrong diagnosis. One halstead guy reckons its the...

Hi everyone, I'm getting around 18.5 k ohms on my multimeter for both dhw and heating thermistors. Does anyone know if that's about right or should it be a bit lower - the boiler is cold, cold, cold, two days cold. Customer getting no hot water and the heating fires and blocks out pretty well...

The one I'm working on has flow and return connection at top of boiler.

Did you ever figure it out?

I'd like to thank you guys very much for your input. I am going to have to power flush - especially on the conclusion i've come to from Mickygs advice. I was up in the loft and could see that at some stage a heating engineer had dosed the system with inhibitors (because they had left the...

Thanks fellas, I'm taking it all in! Jon.

What I mean though, is that if I just clean up the heat exchanger the customer will have a quiet and safer boiler for a time. I'll have a happy customer for a time as well. But that time will be restricted to as long as takes for the heat exchanger to sludge up again. I imagine the boiler...

I chose the gas analyser over the powerflush machine - it all starts to become very expensive - especially when a bloke thinks he might make it back to Aus one day (we don't have central heating). I get another plumber in the area to do an occasional flush for me around 260 quid - it also...

Thanks mickyg, Makes sense - would the circular heat exchanger give the impression of the noise i suggested and cause the boiler to modulate more intensely? - I think it modulates heavier than it should. I've flushed heat exchangers and descaled etc but not one of these suckers, is there...

Hi everyone, I'm new to your site and I am an rgi although most of my plumbing life has been in Australia. And the many boilers old and new over here leave me scratching my head on occassions. The problem I've encountered is the above mentioned boiler which is serving an openvented...
