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.
Hi guys and girls.
So…. Bought an apartment in a conversion rather than new build. Since buying it I’ve been experiencing headaches, sickness and dizziness. At the time I just thought I was coming down with something but then a TV engineer came to install an aerial in the loft and he showed me...
Need somebody competent with pipework in awkward places to fit a destratification pump and appropriate nrv's to a dhw cylinder. Only the plumbing not the electrics
I had an unvented cylinder (and gas boiler) installed by a Gas Safe Register engineer. He later informed Gas Safe Register which issued me a gas certificate. But Gas Safe Register told me I should have a Building Regulation Certificate for unvented cylinder installation.

Hi Folks,
Has anyone got any experience of the Grohe Sense Guard? It's been on the market for several years but seems that there is virtually no feedback on it for the UK.
So either it's so wonderful that nobody feels the need to complain - or maybe nobody has installed one........
I'm in a...

I have a leak in my leasehold flat in a small council 4 storey block of flats – 8 flats in total. In the corner of the bathroom is a cupboard where the soil pipe runs through each of the 4 floors on my side of the building. Within this cupboard there is a T junction taking the bath and kitchen...
Hey guys.
I'm looking for some advice. I had a new combi boiler fitted last week boiler seems to be working fine although the flue outlet is dripping when the boiler is in use. I phoned the fitter and he agreed it needed sorting and would ring to arrange (hasn't phoned yet) I looked at the flue...
I've had a new shower cubicle done and the fitter has installed the wall profiles the wrong way around so the screws are on the outside (pic included).
He also sealed the enclosure on the inside even though the instructions explicitly say not to (though it wasn't possible to seal the verticals...

Hi guy
I had solar thermal installed and wanted an expert opinion, had it installed today and its not working and the installer is to return. I get the impression when it comes to the electrical side the installer hasn’t the foggiest, he replaced the water valve and now my boiler does not heat...

Hi,
I have an unvented cylinder with a water combination valve before the inlet. It has been installed with the "balanced" cold water feed coming straight off the combination valve and not after it. Is this installed correctly? If not, what are the consequences of this connection? Many thanks!
Ive replaced the fill valve contraption and flapper inside which didn't help the slow filling problem.
Also tried it without the t valve connected and the toilet fills up perfectly, maybe three times faster.
The T-Valve that came with the bidet seems to be much smaller inside but so do the...
Hi Everyone. I have had a boiler installed in March 2020 (a replacement like for like Valliant boiler). It has cut out twice with F20. Valliant came out and state that I have "All" my rads off so the boiler cut out due to over heating. The thing is that not all my radiators were off, most were...
