digital
Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing and display of such images. A key advantage of a digital image, versus an analog image such as a film photograph, is the ability to digitally propagate copies of the original subject indefinitely without any loss of image quality.
Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. In all classes of digital imaging, the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image. For example, the medium of visible light allows digital photography (including digital videography) with various kinds of digital cameras (including digital video cameras). X-rays allow digital X-ray imaging (digital radiography, fluoroscopy, and CT), and gamma rays allow digital gamma ray imaging (digital scintigraphy, SPECT, and PET). Sound allows ultrasonography (such as medical ultrasonography) and sonar, and radio waves allow radar. Digital imaging lends itself well to image analysis by software, as well as to image editing (including image manipulation).
Hi there,
I have a Potterton Flamingo 40 (gravity fed system) and it has an old fashioned one day programmer with the clockwork wheel and movable segments to set the on and off times, I want to replace it with a 7 day programmer or 5/2 day one so i can have it set differently at the weekend...

Hi,
I'm after a digital thermostat and would like to know if anyone could recommend one. This is the first time I'll be doing anything to my central heating... I'll be retro fitting it to my existing boiler if that makes a difference.
Thanks,
Pedro

Hi
I am new to this forum, so I thank all in advance for any help.
I have a 30 year old basic gravity heating system with a back boiler (boiler changed more recently). I have a philosophy of if it isn't broke don't fix it, and it has all worked well for many years.
I would however like to...

Hi,
I am having my boiler replaced soon with a Vaillant Echo tech 831 and wanted to know what people here thought about TRV's. At the moment I don't have any and manually just turn the valves down in the rooms that get hot.
Can I not just do the same when I get the new boiler rather then...
