Hi,
For some time now my outside overflow pipe has been leaking a bit, but in the last few days its become much worse. I havent had my central heating on at all over the summer, but this week when I switched it on, the radiators dont heat up unless I switch the water heater on too. I have 2 switches on it, one for heating and one for water. So when we want heating, I have to switch on the water too which is quite expensive to keep doing when we dont need hot water constantly. Could this all be connected? I am a female single parent and have been ripped off by tradespeople in the past, so I would like to know anything before I call someone out. Many thanks
