Installed base (also install base, install[ed] user base or just user base) is a measure of the number of units of a product or service that are actually in use, as opposed to market share, which only reflects sales over a particular period. Although the install base number is often created using the number of units that have been sold within a particular period, it is not necessarily restricted to just systems, as it can also be products in general. For products which are in use on some machines for many years, the installed base count will be higher than sales over a given period. Some people see it as a more reliable indicator of a platform's usage rate.
Installed base is not the same as the total number of units sold at any given moment in time (***ulative sales numbers), since some of those units will typically be out of use because they have broken, gone missing, or been made obsolete or replaced by newer versions.

    multifuel boiler and electrical issue

    I have a Charnwood LA50 inset multifuel burner that has been installed for a year or two now. The problem we have is concerning the pump and a pipe thermostat which i believe is to ensure the water doesn't over heat and to force the pump to run to dissipate excess heat via the radiators. this...

    Oil CH System Installed - OFTEC Registered Tech now 'Disappeared' - No CD10/11

    Hi Guys - first post in desperation! We recently had a complete oil CH system installed (including tank) by an OFTEC-registered guy (a one-man limited co. business). The system works well, and looks (to me!) to have been installed quite competently. Unfortunately, he was due to return to...

    Underfloor/boiler set up.

    I've installed nuheat underfloor through my house. It doesn't seem great in that you can feel were the pipes are so you get hot and cold lines across the floor surface. That said I haven't had it on for more than about 8 hours but I would have thought this would be enough to warm the whole...

    Is this really how two radiators should be installed in a ground-floor extension?!

    Hello, I'm having a 'little' dispute with my builder, mainly over his project management. I think his bizarre scheduling has meant we paid way over the odds for plumbing services - and ended up with something a bit rubbish. We've had a ground-floor extension built so the back room is now three...

    Vaillant Ecotec vs Worcester Greenstar system boiler?

    Wondering which is best to go for here. Everything I read, they seem about even. Vaillant Ecotec I'm told has a stainless heat exchanger and Worcester have far superior customer service. Any advice on these two? :dead: I can get the Vaillant for about £75 less than the Worcester.
