hotwater
A geyser (, UK: ) is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around 2,000 metres (6,600 ft) where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion).
A geyser's eruptive activity may change or cease due to ongoing mineral deposition within the geyser plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention. Like many other natural phenomena, geysers are not unique to planet Earth. Jet-like eruptions, often referred to as cryogeysers, have been observed on several of the moons of the outer solar system. Due to the low ambient pressures, these eruptions consist of vapor without liquid; they are made more easily visible by particles of dust and ice carried aloft by the gas. Water vapor jets have been observed near the south pole of Saturn's moon Enceladus, while nitrogen eruptions have been observed on Neptune's moon Triton. There are also signs of carbon dioxide eruptions from the southern polar ice cap of Mars. In the case of Enceladus, the plumes are believed to be driven by internal energy. In the cases of the venting on Mars and Triton, the activity may be a result of on solar heating via a solid-state greenhouse effect. In all three cases, there is no evidence of the subsurface hydrological system which differentiates terrestrial geysers from other sorts of venting, such as fumaroles.
Hi Gents,
I'm currently doing a Job at a small warehouse where i've been fitting a Basin and toilet, the owner of the premises is a close friend of mines and has just recently taken over the premises.

Hi, I have a shower unit that I cannot identify, there are no names or marks on it and it was in the house when we moved in - so it must be more than 12 years old. The thermostatic cartridge has failed, the shower runs cold all the time despite there being hotwater available to it. I have...

I've recently moved and the new house was built in 1988. It has the original boiler, controls etc.
I have a couple of issues. First of I've tried doing so research, and think I have a vented indirect system.
The first...

Ive just moved into a new house which has an older boiler installed.
It is a Glowworm Ultimate with a Lifestyle LP112 programmer.
I cannot get the central heating to switch on by itself, it will only operate if the hot water is also switched on at the same time.
If i switch on the...

There is a white box on the wall ( House sitting for Dad ) called a watchman flashing a 'c' at me. Does this mean I have run out of oil?:confused:
