Sarah,

Combi boilers are 'on demand' appliances, and not like the boilers that heat up water that then gets stored in a cylinder waiting for a bath to be drawn or a tap to be run. Therefore, if your boiler is switched ON, and is being fed mains pressure cold water, then unless there is no gas or the boiler is faulty, it will heat up the water the moment a tap is turned on. If the Central Heating is also on at the same time, then a valve inside the boiler automatically switches the heating over to the domestic hot water side, at the expense of the central heating. However, as the time taken to heat the water is usually very short, this has little impact on the heat being released from the radiators, and as soon as the hot taps are turned off, the central heating side takes over again.

The 'programming' is a timer of sorts that only effects when the central heating comes on and goes off again. It has no effect on hot water in the taps.

As you have mentioned that the boiler has been 'fixed', I am therefore of the view that it is still faulty. But unless you provide a model number, it is impossible for anyone to say precisely what you need to check to ensure all the controls are set as they should be. I would therefore get the plumber back toute suite! ;-)

Kind regards Nigel
