Boiler ignition

David.G · 22 Sep 2006

I have a rather old glow worm fuel saver 40-50. Wether it is heating the hot water or central heating it only operates for about a minute then turns off for the same amount of time then refires. It keeps doing this for the duration of the programmed time?
Is this normal for this type of boiler?
Cheers

Check if the pump is working. Have a listen to it through a screwdriver (that's the tool, not the drink), blade on pump, ear on handle.

mind you have enough of the drink and your pump will sound like mozart

Could be tired pump, sludgy system, or the boiler not getting hot enough.

If you turn the thermostat on the boiler, up, the pipe coming out should get too hot to touch.

Thanks for all the ideas.
The pump is new about 6 months old , the system has been flushed thoroughly and has inhibitor added and OH yes the pipes are good and hot! . Any other ideas?
possibly a boiler thermostat?

It may well be correct!

A boiler engineer would check the flow and return temperatures and the gas burner pressure.

Based on the results obtained he would make a judgement on the situation.

Just because a pump is six months/days/hours/minutes old does not alter the fact that it needs to be checked to confirm that its operating correctly and the valves are open!

You never know what's lurking in pump valves if you don't change them.

Then there's pipes
