Change the boiler?

The boiler is a 3kw 75 litre immersion tank. It dribbles and is huge. I could have it fixed or I could replace it. I was thinking or putting in an insta heat boiler. (works like an electric shower) it's give me space for a washing machine here also!

I'm afraid that I've grown bored by this project so I've done half arsed quick finish on it.. The box works fine but has no lables and I've made a few horrible Bodges internally. Not as bad as the previous pics but not far out.
