I am new to cycling, I have a Merida road bike with alloy rims, this may sound silly but when I'm cycling over 25mph and touch the brakes it seems to heat the rim so quickly the wheels feel like they are starting to wobble.
Has anyone experienced this and any idea on what it could be?

No experience but the first thing that springs to my mind is check the pads. Probably the easiest to check and cheapest to change.
 
I would suggest that there is nothing wrong with the rims or pads, instead of pulling on the brakes in one long hard pull, pump the brakes, ie apply the brake for a second then just ease off before applying again. that should stop the wobble feeling and also reduce the rims over heating somewhat, if you pump the front and rear brakes alternatively you maintain a stead braking sequence.

I tried the whole brake thing soft short burrs both wheels and the same is happening. It is quite scary as you can imagine, 40 mph down hill and the wheels just feel like they are going to fold in half.
 
I noted that you say you are new to cycling, then in your last post you say that at 40 MPH downhill it feels that the wheels are going to fold in Half, maybe you get that feeling because you have yet to get your mind set into the fast downhill mode. May I ask did you buy the bike fully built, or did you have to assemble it from the box. If you build it yourself I would check that you have set it up correctly.
Check the headstock fittings check they are tight and no play on the Headstock bearings,
Likewise make sure that the bearings are not too tight.
Silly as it might sound, many a person self assembling their bike have ended up with the front forks pointing in the wrong direction.
Check that the front axle is seated correctly and running true.
The check the rear wheel to see if that it is correctly seated and running true. as a incorrectly rear wheel, will effect the feel of the bike.
Check If the tyres need to be set to either front or rear fitting.
Check your tyre pressures, as even a slightly under inflated tyre can give adverse handling conditions.
Failing that take it to your LBS and get them to give it the once over.
