Argh, finally when I get one problem fixed in my flat an old problem comes back again. Heating came on as normal...then I heard a dripping noise. It seems the boiler has a leak (or at least one of the pipes surrounding it). What to do? Is it safe to leave the boiler turned on? I have turned the heating off, though if its safe will put it back on timer for the morning, else I will definitely struggle to get out of bed in the cold! This is a one year old flat...nothing but trouble so far. Think the boiler should be condemned as this is not the first time it has caused problems!!
