Boiler constantly heating water

[LeeWooding]

Hi,

I hope someone might be able to help me - I have recently had a Worcester Bosch 24cdi combi boiler installed.

I noticed a couple of days ago that the pipes were really hot under the kitchen tiles and on closer inspection it seems as though the oiler is constantly heating water.

I have only three taps in the house and there is no obvious leak on any of these so I don't think that there is any need for the boiler to be constantly firing. It is on an Eco setting which is designed to stop it from per heating in any case.

It heats the water to 60c and then allows it to cool to around 50c before kicking off again. Naturally, I'm worried about the volume of gas I'm using.

Am I just being dull or is there a problem here?

It sounds as though you have the pre-heat switched on.

Rather confusingly, the pre-heat is off when the ECO light is on.

We have found the cause I think.

Tried numerous times with switching the Eco switch to one setting then the other but the result was the same.

We have found that we have a leaking pipe under the kitchen floor which is tiled. As it is an extension to the house I'm unsure as to what this is tiled onto. Looks like it could be concrete so a tough job to get to.
