Thanks Oilhead for your reply, the new box is the one recommended as a direct replacement for the original.I have moved one of the terminals in the base to suit the new control box and it's now working.Thanks again for replying. Cheers.

Hi, Quick question,I have a Danfoss BHO 64 control box which needed replacing as it was not bringing in the solenoid,everything else is working (spark etc) I have had a equivalent replacement part but when fitted the opposite happens i.e no spark but the solenoid kicks in.My question is re...

Hi got a small problem ,been called to a house with a system boiler which is part of a sealed central heating system which indirectly heats a dual coil cylinder the second coil is from a solar panel.The hot water is gravity fed.There is a twin channel programmer but no other controls in the...

Hi i,ve got a small problem with a Worcester heatslave 18/25. Control box is a dk 970 and its a bentone burner.The burner goes through all the proper sequences oil pressure is right and the burner fires for about 5 to 10 seconds then goes to lockout.It all points to the photocell but the old one...

I have a problem with a Worcester camray 25/32 utility oil boiler it has a riello burner.The problem is there is excessive smoke coming from the flue even though the combustion tests and smoke test are spot on,the smoke is white.I did notice that the smoke test had some moisture on the paper...

Thanks Boilerman2 you were absolutly right the diaphrams from both boilers are the same,picked one up yesterday from local Plumb Center and fitted it this morning jobs a good un :D

Hi I need a little help, I need a new diaphram for a diverter valve on a Eurocal exterior 90/115 oil boiler .I cannot find any spares list in the installation manual or anything on the net,any help in tracking down this part would be very welcome. :(

Hi vicvapour and boilerman 2,Ihave been back to the heatslave 12/18 boiler and tried out your suggestions but no luck there.But I decided to trace the pipework to the first rad to see if I could find a blockage or airlock in the system,as I did this I noticed some new boxing in and paintwork...

Thanks vicvapour and boilerman 2 for your replies I will try out your suggestions and let you know how I get on.

Hi ,called out to a heatslave 12/18 which has been idle for many months.To cut a long story short I got the boiler working.The problem is it is only heating up the hot water.The diverter valve is working as is the pump.All the wiring has been checked all the valves are open everything is...

Thanks Tony for your reply the filling loop is disconnected but the pressure is still creeping up and it does drop when the hot water tap is run I think you may be right that the secondary heat exchanger is the problem .Can these be fixed or will it have to be replaced?.

Thanks MrGassafe for your reply,I know that the pressure rises when the boiler is working but it,s the amount it rises that worries me.It keeps going up until it blows off through the pressure relief valve which leads me to believe that it is getting mains pressure somehow which is why I think...

I have a worcester heatslave 15/19 oil boiler which has a rising pressure problem.The pressure gauge rises slowly when in use and then drops when not in use.I have disconnected the filling loop and checked the expansion tank which seems to be fine ie correct pressure and no water showing .The...

Thanks Oilhead for your reply, the boiler is well insulated and I think the mixer valve is set to maximum I also think the boiler is set to 60 deg.Do you think the flow will increase if I drop the temperature by say 5 deg?.Iwill try and get these settings changed and see if the flow increases...

Re Thermsaver 70/90 external boiler. The boiler is working fine on the heating side but the dhw flow/pressure is very poor(approx 40 mins to fill a bath).Can anyone suggest a reason for this .The mains feed to the boiler is 3 bar with a flow rate of approximately 17litres / min which seems more...
