Inherited a baxi 105 moving into my latest place and it's been an uphill struggle to get it leak free and behaving.
Finally it's at a point where we have no leaks and a level of a reliability.
The only thing that remains, and it may just be pure paranoia at this stage, is the way the boiler behaves when using CH.
Say I whack the thermostat up to trigger the boiler, it will fire up and slowly ramp up till it hits 70 on the boiler panel and maintain this for a good while, rads heat up, happy days.
However after any decent running length, I'd say anything after 20minutes it begins to get into a cycle of actions that I'm not sure are right.
The flame will go out, pump will continue to run and the panel temp will drop usually down to 30/40 after x minutes. At this stage it will fire back up, get back up to 70 pretty damn fast, then shut down (pump still running) and do this all night long.
During all this, the target temperature on the thermostat is never met so that is fully out of the equation.
Do Baxis do this by design? I would have thought it would just try and maintain as close to 70 as it can through flame and flow management rather than on/off'ing all the time.
Out and return filters have been removed and cleaned btw (the out was fine, return had a tiny bit of gunk), no leds ever flash or warn and the boiler doesn't need a reset during any of this.
Trawled the net but can't find anyone that's complained of this, but I still wanted to just check if this was expected behaviour.
Cheers, Harry
