Hi, I was just wondering/hoping that someone might be able to give me some advice on my currently not working central heating. Its only 5 years old but stopped working yesterday.
It is switched on, the thermostat is still clicking when it gets to the temp (it only does this when CH is on) and the boiler is still firing but system is still cold. Over the last few weeks I've noticed that the pump has been rattling a lot so wonder if this could be the problem.
Does anyone have any ideas on what problem might be and likely cost to sort out? I'm not doing this for a 100% accurate diagnosis or cost, its just that I don't have any ideas as to cost/problem so would just like to have some ideas when I call a plumer.
