Plumbing Question

Water tanks

I believe I have a hot water tank and a cold water tank above it. I would like to remove the cold water tank to provide more space, why would I have a cold water tank and not be connected straight to the mains?

You will find out when you remove the tank.

There are different ways of plumbing in water and you don't need to learn the hard way. I think you need to post the job and get a professional to give you a quote.

It was the norm for the mains to fill a cold water cistern that then supplys the whole house. Then you always have stored water should the mains be shut off. This is also done if you have poor mains pressure. Primarily the cold water cistern provides water to your hot-water cylinder and is where the hot water cylinder vents to. Hot water expands and needs to some where or it can explode.
If your mains pressure is good enough you could change your hot system to a unvented sytem giving you mains pressure (usually reduced to 3 bar) hot water and cold water from the mains. The cylinders are not cheap but it means you save space and can have hot showers at a decent pressure.
