[cc120]

Hi Folks

I had installed, by the council : (, the Worcester Bosch Greenstar 24i combi boiler, which ignites when not in use, and usually when not in use for the whole day. Is this the boiler regulating it's thermo, when it gets too cold, as explained by the contractor, or any other reason?
