A gas-filled tube, also commonly known as a discharge tube or formerly as a Plücker tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. Gas-filled tubes exploit phenomena related to electric discharge in gases, and operate by ionizing the gas with an applied voltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge. A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps, sodium-vapor lamps, and neon lights. Specialized gas-filled tubes such as krytrons, thyratrons, and ignitrons are used as switching devices in electric devices.
The voltage required to initiate and sustain discharge is dependent on the pressure and composition of the fill gas and geometry of the tube. Although the envelope is typically glass, power tubes often use ceramics, and military tubes often use glass-lined metal. Both hot cathode and cold cathode type devices are encountered.
We've just bought this house, and looking around the loft there is a large water container (clean) and a much smaller container next to it filled with mouldy looking gunk and a ball valve (?). This doesn't look good. But I have no idea whether it's in use or redundant and why it's gunked up like...
I have a water filled towel rail which has been working for several years.
It is now getting very hot and making a noise.
Do these loose water over time and need topping up?
Could this be the problem or a faulty thermostats or element?
Any way to diagnose the problem?
Thanks
Hi
Due to waiting a week for British Gas to come to repair a leak on the radiator - only for them to arrive and say they haven't got the part and so I will have to wait till Monday, I purchased a Status 7-Fin Oil Filled Radiator so I didn't freeze to death.
I plugged it in last night and it...
Hi
I have an occasional noise from the toilet. The toilet is less than a year old and sometimes after the toilet finishes filling back up there is a vibration noise. It doesn’t happen all the time. Just wondering what this could be.
Thank you
Approval queue - Leave listings that aren't fully filled in Unapproved for now. I need to work on them before they go live with just an email address and phone number in. :)

Hello,
I was hoping some one can give me some advice, Sunday morning I came down to a wet floor and no heating or hot water. I initially thought that the heat exchanger had gone in the boiler. After a lot of clearing up and drying out I managed to get some one to look at the boiler and they...
evening everyone,
First time poster here. Have always had oil heating but this is a first for me. Moved into a new house 3 months ago with a Camray 5 oil boiler installed on it. Not one issue with it. I filled my tank this week (there was still 150 litre left in it) and since then there is a...
Hi, I've just bought two new designer radiators. When fitting the valves I noticed that theres a good few tiny metal balls inside. Just wondering, are these from the manufacturer process... I guess they are and will need a flush before fitting to remove as many as possible. Is this normal? None...
Hi
ive spent most of the day getting the sludge out of my radiators. Filled the system back up, bleeded all the radiators from the ground up. Turned the central heating on (expansion system) and the boiler fired.
Next thing I hear really loud gurgling noises from the hot water tank and loads...
I have a 70kW woodchip biomass boiler installation including a 650 litre buffer tank, all installed in 2014. The buffer tank loses pressure from say 2.58 bars to 0.00 bars within a 48 hour period. Yet there are no visible signs of any water leaks,
When this tank is drained of water then...
Hello all
I have recently moved in to a property that was vacant for 2yrs. After spending £600 having a service, replacement hot water flow switch, pump valves, top up valve, oil pump, solenoid actuator and several weeks of the engineer coming back and forth before we got any heating, it worked...

How many of you come across benchmarks that are not filled out? I have assumed it's an uncommisioned appliance if this is the case but more often than not I find out its been installed by a gsr company and has been signed off and has a notification.
So does a non completed benchmark make it...
Hi all,

I need to hang a 35kg rad (not including water weight when filled) onto a plasterboard wall. It comes with four supporting brackets but the fixings supplied are for a solid wall. Can anyone advise the strongest/best fixings to use to hold this safety in plasterboard?
