vent
A hydrothermal vent is a fissure on the seafloor from which geothermally heated water discharges. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart at spreading centers, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents.
Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, hydrothermal vents may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa, and Saturn's moon Enceladus, and it is speculated that ancient hydrothermal vents once existed on Mars.
Hi, Could someone please help me. The original vent section of he soil pipe ha been cut off and replaced with a bossed pipe. connected to this is a 50mm waste pipe from the basin and bath into the soil stack. This 50mm pipe also serves as the vent pipe for the system, going up the wall and...
F&E tank, big house, full of slime, vent capped off. Why would someone do that? Boiler wired up weird too, on HW, tank stat opens 2PV but doesn't turn boiler on, valve only wired to the stat.
Any logic in this? Cable runs are easy, boiler directly below cylinder.
Cheers
Hello folks,
converting open vent system to sealed heating system (hot water to remain vented) - the boiler is fine to convert (glowworm ultimate), as is cylinder. I know it needs expansion vessel, safety valve, gauge, filling loop etc. Initial query: can the safety valve go in the airing...
Whats the point of this when you want to change a rad and re-pipe? All it does is hold the water in the f and e tank. The existing rad pipework drains anyway with the pipework under the floor and when re-filling the system if there is any carp in there this will still drop into the pipework...
Hi,
Can I use an external air admittance vent, such a floplast, inside. To me the inside and outside one are very similar except for the protection that outside one has around the vent.
Many thanks

hi i was just wondering if this is normal or it it was a mistake. the F+E tank never had a vent on it, we drained it down and it took 2 hours to get up and running. some of the air was coming though the cold feed to the primaries to the tank. I've had a look though my college books but can't...

Hi all,
I have about 120mm dia (four and a half inch) circular vent hole in my kitchen wall.
The issue I am faced with is that Most of the vent kits are either 100mm, 125mm or 150m.
The vent is for extractor hood. Manufacturer recommend min 120m but prefer 150mm for maximum extraction.
What...
Hi,
I recently bought a flat in a building block built 15 years ago. Since I moved in there has been a smell of sewage. After putting silicon on pipes connection the smell was still there. I finally (after making a hole in one of the walls) discovered that the sewage vent was behind this wall...

Hello,
Boiler not getting a sl from this boiler mate and not firing. Never seen one before boiler mate 2000 that is. It looks like the boiler gets a switched live from there but there is no voltage on the sl at the boiler mate. Every other connection has power when it should.

For years I've had the following auto air vent in the airing cupboard.
It tends to weep when set to the open position and so today I've fitted this Honeywell EA122 jobby.
It vented automatically as it should when refilling the system but with a manual vent I was able to shift more stubborn...
