Guys, appreciate the advice and that you're saying the right thing.
I've replaced this fan before, and got a corgi chap round to check everything over.
Unfortunately, my financial situation doesn't allow me to call an engineer round to diagnose and replace - I'm not even sure how to pay for the fan at the moment, and may have to take out a small loan - obviously I dont want to, but I need hot water.
Would really appreciate your advice on this - I would get a corgi (gas safe) guy round, but I'm in a desperate situation so don't have a choice!
Please help?
You do have a choice, TURN THE BOILER OFF!!! and wait until you have funds to pay a RGI, as mistakes can be life threatening.
Phone around for a price. They are quite reasonable.

I realise that you're all doing the right thing by saying I should get an RGI, but you don't seem to understand - I'm in about 25k of debt as my partner's been unemployed for about 3 years and can't get a job.
To pay my bills each month I have to juggle credit cards and I earn less than I have to pay EVERY month.
It's because of this situation that I can't get an RGI, and it's not really practical to live without hot water for the next few months, or longer.
I'm only asking for advice!
