Hi, My greenstar 35 CDi, which as recently been installed turns on the central heating the same time as hot water demand. Does this mean an incorrect installation or hasn't the boiler been setup correctly? The plumber will be back and I will mention it to him, but in the meantime has...

Hi, Maybe I should post my question on the general building forum. Box is to be cut out from breeze block. Cable will lie on the surface of the breeze block. Quite simple. Not rocket science. Simple question.

Hi, The block depth is 100mm. The breezeblock is quite soft material, not concrete - you could easily cut out a socket with a chisel. Thanks.

Are there any guidelines for the maximum depth of box which can be cut out of a breezeblock. I have two breeze blocks supporting part of the roof of an extension, and therefore cautious about weaking the supporting wall. I need a 35mm single lighting box cut out to 25mm. Would I be ok to do this ?
