New pump wasn't much help either. My plumber did ring but can't get to me until Monday. The old relay is a tf 830.2 the new one is tf 830.3 but I do not see that a problem. However the new one does not like the situation. I have decided to give up for today, thanks for everyone's help. I will...

I have put another pump on and that doesn't help. I think I try a sludge hammer next.

No water in the oil. Just about to change the pump to see if that helps.

No Gem outlet fitted, l'm afraid.

Thanks awoken for your suggestions. I have a look at that. No it's not a balanced flue system.

Thanks Slapper for the suggestions. I have just replaced both the nozzle and the coil but neither has helped. I tested the photocell earlier which appeared to be ok and from my limited experience fuel appears to be ok.. Whatever the problem the relay doesn't like it.....I'm getting some...

Hi all l need some help with an oil fired boiler problem. I have txt the plumber who services it in the meantime we have had no heat since last night. Iam a spark by trade,so l have a little understanding what I'm doing. I have replaced the ignition tx and the relay which I believe to be faulty...

No ricicle. The supply voltage for the boiler comes from a 400-24 transformer. 240v (L & N) is for the blow motor only.

Yes Spark123 you are correct. The neutral is needed to control a blow motor for a boiler, but only after the motor is running I'm at odds with my Boss who thinks taking a neutral from the boiler is not a problem. Is there anything I can quote to strengthen my case. Regards

I have a 3 phase motor and controls supplied by a 3P+N supply. I need to relocated the cabinet to another area which has only a 3 phase supply. Can I use the motor to to give me that neutral in the new location. Many thanks, in advance

I have part rewired my house (to be completed in the near future) to a different position to the old consumer unit. The rewire when finished will have 1x cooker, 2x sockets, 1x electric shower, 2x lights, 1x external supply for small compressor for septic tank, 1x external supply for oil fired...

Many thanks Dum Spiro Spero. Keep up the good fight

But does it apply to rewires ?

I know the min. and max. mounting heights for sockets and switches within a domestic premises, but am I compelled to to stick to these measurements ?

I have a 70 watt discharge light, controlled by a 13 amp time switch via a 240V 10 amp relay. The coil on the relay has failed, Do I put the fault down to a faulty relay or do I need to change the relay to a different type ?

Also, Many thanks to oilhead for your posts.

Thanks Mike for the offer, but I had a good look at it yesterday and I have now got the system running as it should. It was the valve drive that was at fault, I don't know what I had done the first time I replaced it, but every thing is OK now. Many thanks for your input.

Mike2007.....With the CH on, the pump won't run until the lever of the drive for the diverter value is moved to the manual position. This movement of the lever depresses a micro switch or contact (call it what you may) and I would guess moves the brass valve into another position. Only with the...

Oilhead..The drive is a honeywell. With brass, as opposed, to plastic

Oilhead..Both HW and CH stats are cutting in and out. The drive itself is moving, but then it appears to slip and I get this clicking noise. I'm thinking is the brass valve itself faulty! But then again the system works if I put the drive to manual and depress the mirco switch.
