I recently had water overflowing from my central heating header tank. I replaced the ballvalve, which had no effect. I isolated the water supply, and it still overflowed (about 1 gallon per week). In this situation, the only way for water to get into the central heating system was via the coil in the copper storage cylinder. If your central heating header is higher than your cold water storage, then it would happen the other way round. I hope this is not your problem, or you are competent at diy, as the plumbers will charge

What is an overflow tank in a vehicle for?

It has a tube between itself and the radiator. As coolant heats up, it expands. The expanding coolant goes through the tube into the overflow tank. Later, when the vehicle is shut off and the radiator cools, the overflow is pulled back into the radiator. The system is "closed", hence the coolant does not just "dribble away" when it expands like it did in vehicles many years ago.

What makes a river overflow?

Lots of things can cause it. Heavy rain can be one cause. Rivers can also get blocked up making it more difficult for water to get through. They need to be dredged every so often to prevent that. Sometimes work can cause rivers to be diverted or blocked, which can cause them to overflow.
