Got back from a weekend's racing at the weekend to a cold house.
The heating was working as it should on Friday night when we left. At 12.30 pm on Saturday I remembered the 'away' mode so went into the app to set it for 1 day.
Around lunchtime on Sunday I checked the app and the actual room temps were between 12c and 14c with the setpoints looking as they should be or higher (18/19c)
So I used the app to turn the heating 'off' with the quick action and then on again, thinking that this may clear things. I then forgot about it.
Got home 11pm last night and the house was cold - all room temps were between 12c and 14c, the BDR91 had a constant green light. Checked the controller and everything looked normal and there were no errors in the log. The boiler was not running.
Ran the hot water and no hot water so obviously a boiler problem rather than an Evo problem (phew ) but no red light on the boiler. Hubby fiddled with the boiler, switched it on and off a couple of times and it fired up. House was warm again within half an hour (although not up to actual temps.) The boiler pressure had dropped below 1.
So a few questions/observations have arisen from this.
Boiler is a Ravenheat Combi boiler put in by the previous occupant around 2010.
Looking at my logs on Smartthings and on my Loop graph, I used no gas, so boiler probably failed around the time of me setting the Away quick action.
Did my Evohome indirectly cause the boiler to fail (ie not using either heating OR hot water for a period of time caused the pressure to drop so therefore boiler failed.)
Should the Evohome controller not have picked up that there was a problem and shown an error or is the system not that clever.
Is this a sign that the boiler is on its way out? This is not the first time this has happened - last time I was at work and hubby had no hot water so rang our plumber who just reset the boiler (Plumber does not rate our boiler but when he installed our Evo in August 2014 he didn't see any need to replace the boiler after we asked if we should.
