For those who are thrilled about still having 20 - 25 year old cast iron boilers I would say don't leave them on if you go away for long, like over night !!
We had one and the boiler was still good but the gas valve will be the same age and that is a disaster of a weak link. Fortunately we were at home and during the night woke up to find the house sweltering hot and the sound of boiling water. The CH time clock had turned off but the gas valve had remained open ....
I asked the engineer who replaced the boiler and of course the gas valve with it what eventually happens. "Bottom melts out of the header tank and then you have hot and then cold water running through the loft ceiling. Yes! it happens ...".
New boiler with many more built in safety measures, like two gas valves in series has been in use for some years now with no problems. I feel confident about leaving it on whilst we are away and it must have paid for itself in economy over years we have had it.
