https://www.googlenestcommunity.com/t5/Nest-Thermostats/Heating-issue/m-p/67282#M15289 <P>I've just moved into a place with a nest controller for the heating, connected to a hot water tank &amp; an old outside oil-powered boiler.</P><P>I've sussed out how to set the controller, but even when it's switched onto manual/heat/19⁰ and seems like it should be running, nothing happens. There's also a circular button on the wall next to the water tank, and it seems that when I press that, the heating comes on for a short while, then switches off again - even if both the controller and the app are showing that the heating is on.&nbsp; (It doesn't always seem to come back on when I hit the button either...mind of it's own!) Any ideas to help me keep the heating on for a bit longer/stop having to light coal fire!&nbsp;</P> Mon, 20 Dec 2021 19:42:43 GMT Birdie1 2021-12-20T19:42:43Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Heating-issue/m-p/67282#M15289 <P>I've just moved into a place with a nest controller for the heating, connected to a hot water tank &amp; an old outside oil-powered boiler.</P><P>I've sussed out how to set the controller, but even when it's switched onto manual/heat/19⁰ and seems like it should be running, nothing happens.
