We had a vailant system boiler installed a few months back and it's been bugging me that it seemed to be on when not necessary
Now, it's 27 degrees, we have no hot water call since a few hours back, no heating call yet I can still hear it chugging away
Screen just shows a timer or nothing when I check and it does eventually stop
But what's going on? If I'm not asking for anything then shouldn't it be silent / off
Edit.
Here's where my head is at now (per last post)
- I'm not convinced the wiring is correct
- I think what's happening is that the thermostat in the water tank is detecting drop in temp and telling the boiler it wants more heat
- The boiler has an off / on defined by the thermostat hub (Drayton Wiser) which is saying that the hot water isn't needed.
- Because the wiring isn't quite right its therefore getting a call for heat from the local tank thermostat but nowehere to push it as the 'hot water' is off. This is causing it to go into pump overrun to dissipate that heat
Is this even possible? It's a vailant ecotec
