But if a strange one this...
Oil fired boiler in a bungalow (all pipes run up through loft space and drop down to rads).
Boiler fires and runs. Pump seems to run and get hot water to all the rads but it doesn't flow through and return. This has all happened at the same time. No evidence of air in the rads and with bleed screw open there is water flowing.
To top it all off... Pump and 3 way valve relatively new and this all happened suddenly.
Any ideas?

Sludge in the system restricting flow ?

But a sudden stop? :-\
It was powerflushed to within an inch of its life 3.5 years ago too

I suspect a bit of air/debris in the pump as I've now got it running properly again (I think!) :-\
-
Tank getting low? Starting to rot away inside?
My gran had similar in her bungalow, former warm air system, replaced with boiler/rads fitted from above :D
-
Which tank? Oil is ok... Getting low but still plenty and a plastic tank. Besides, it was heating the water in the system, just not pumping properly. I think it was air/debris in the pump

Meant the oil tank ;) might be picking up a bit of air if it's a syphon connection rather than gravity fed as the level dropos. Plastic tank helps with crud (or lack of) but might still suffer from condensation inside :-\

If it's ok now, you're diagnosis is correct, stress not.

Oil and water systems are totally separate, surely?

Should be, maybe the head gasket's gone? :-\ ;D and don't call LD Shirly! :D ;) :)

They are, but you're right, if it's heating the water, then it isn't a fuel issue ;)

Haven't you got some teenagers to sort out somewhere? Wales, maybe? ;D

My mums bungalow is similar set up except gas boiler and does the same thing since its been fixed. The returns on the rads take absolutely ages to get warm but the rads are hot.
Ive put it down the 'intelligent' pump the plumber fitted Apart from its suppose detect air in it and will keep reversing the flow for 10 mins to try to shift the air up the expansion pipe, its also reduces the flow speed to what it thinks is needed. Some careful balancing of the system was needed to get all the rads hot.

No such cleverness here I'm afraid...

Ok, but are the rads balanced? if not more water will flow through the ones nearest the pump....

It was all fine and just stopped flowing (well, as fine as it gets with one rad that is a known sludgy mess and getting replaced this year). They need a bit of tweaking again now as I've been messing about trying to get it working.
As I said, I seem to have temporarily cured it so hopefully that's that sorted until the summer!

ok, good :y
Be worth considering fitting a magnaclean when you do the rad work.....further sludge will collect in that instead :)
Plumber fitted one on mums system after he had power flushed it :y
