Do I need a new tumble dryer

[derekthehamster]

I've just realised that my small tumble drier is still going strong 15 years after I bought it. It's only a small one and it cost £100. My concern is that it might be more economical (electricity wise) to get a new one? Are newer ones more energy friendly? I'd still only need a small one.

During the winter I probably use it most days for about 30-40 minutes.

the new ones are much more energy efficient, we replaced ours last year, it costs a lot less to run, but I priorities the AAA rating.
