What causes a hot water cylinder to overflow?
Why does my hot water cylinder overflow from time to time? When water is heated it expands; this is called thermal expansion. When heated from cold, the volume of water can increase by as much as 3%. For a 180L hot water cylinder, this could be as much as 5.4 litres.
Why is my condensate pipe leaking?
The condensate trap and pipe come straight out of the heat exchanger, which means that if it cracks or pinholes, it will cause system or mains water to drain into the condensate pipe. What may lead to the condensate pipe leaking is if the hot water causes the pipe joints to fail somehow.
