I have a GlowWorm swift flow 75e/80e (Not clear from the casing which model no. it is) which has been in place for at least the two years I've been in the property. Up until the last three months it has provided HW/CH on demand without fail.
In the last three months neither the thermostat control for the CH or requesting HW from the tap have proven reliable in getting the boiler to ignite. Also, once it has ignited, it doesn't always stay on until the request has been closed (which has added a certain unwelcome excitement to showering).
The most recent change is that the pressure gauge will now make its way up to about 2 bar once the boiler has been on for a period of 1/2-1hr, when it previously wouldn't usually stray above 1-1.2 bar (resting point is about .95 bar).
This is the only noticable problem with its performance, as it doesn't seem to be giving any other signs that there is a problem once it is up and running. It just seems to have become unreliable in starting and stopping.
