Halstead boilers have always been cheap and not very reliable.

Sounds like the lockout is the boiler over-heating - because the gas valve is not modulating.

The modureg (modulation regulator) on the gas valve controls the flame, if the flame is excessive the boiler will over-heat.

A modureg if available or a new gas valve should solve the problem.

but theres one problem the boiler does that only when is not used for lets say 8 hours or more then when its time to use it its on lockout
in other words you dont use it and she goes in to lockout on its one!!!!

the gas company is doing mains gas work up the road from me since then the pop pop thing started on the gas burner do you think as got something to do with? but not the lockout as that started earlier on its one without usage.
do you think its better for me to get a new one ex:vaillant as i think its better if not the best ones in the market and more reliable i got a friend that works for swale heating and he does a good price for me supply and fit a vaillant EcoTEC Plus 837 for £900 with all the certificates
thanks

Have had a few jobs where water gets in the gas pipes and causes problems with gas pressures - get an engineer out.

It definately goes to lockout without being used - you're 100% sure ?
no one opens a tap before going to bed ?

Sometimes if you open a hot tap, so the diverter operates the microswitch but you close the tap before the burner comes on - boilers can go to lockout as it has not completed it's sequence - tends to happen on older boilers.

As for the vaillant - defiately includes fitting ??? if so - great price
as the boilers are around £900 to buy. If you have the money i'd go for the vaillant as it'll last for many years. This might be the first problem with the halstead but you tend to find with older and cheaper make of boilers after the first problem there'll be more in the next year or so.
