Regarding the temperaturefluctuation or cool running it could be a faulty cartridge however to checkthis, see if you can get hold of the hot supply pipe before it enters theshower or perhaps as it leaves the boiler.

 

If when holding this pipe thetemperature fluctuates or goes cool then the problem is not with the shower butmore likely with the boiler as the shower can only deliver what the boilersends to it.

 

Disregard the temperature at thetaps as they have a different flow rate.
