If you are into smart devices, you must have heard of Google Nest Thermostat. It is a smart thermostat with the first iteration launched in 2011.

However, people who bought the latest version of the Nest Thermostat released last October have reported a number of issues with their devices with some preventing the thermostat from working.


With that being said, it looks like users are facing another glitch. According to recent reports (1,2,3,4,5) from Nest Thermostat owners, it looks like the hot water schedule option is not working for some. Others said that when they choose the heating option, the thermostat turns orange but does not heat.

It looks like even though the device says it is heating the option in the app stays greyed out. Some said that they tried replacing the Nest Thermostat with another one and their water started heating as intended, indicating that it is an issue with the Nest thermostat.

Generic solutions such as restarting the thermostat do not seem to help either. This is a really frustrating issue since it is winter season in many parts of the world.


Hi – My hot water isn’t working on schedule. It says it’s “on” but the background in the app is still grey. Also when I boost, again it says “on” but is grey still and there is absolutely no hot water. When the immersion is turned on on the hot water tank, and I switch the nest to boost, then and only then the “on” screen glows orange. I know then that the hot water is working – I think the nest isn’t. Have done a restart on the control – what more can I do please? Thanks!

Unit worked fine for 2 years. Now glows orange but no signal being sent to furnace. 2 other zones on our same furnace with non nest thermostats work fine. I’m feeling its the firmware update as some others have mentioned but Google help won’t acknowledge that is the issue. Anyone in Community able to help since Google won’t acknowledge the problem?

If you are someone who uses schedule for hot water, a user stumbled upon an option in the settings menu that allows users to turn off or on the scheduling. They said that toggling the option fixed the issue for them.

So I just went into settings on the thermostat (push it and then select the cog icon) then scroll along and up popped an option that said “Hot Water Schedule” and it could be set on/off

With Google and Nest team yet to say anything on the matter, it looks like users will have to manually turn on their furnace and water heating solutions or use another thermostat.

We hope the Nest developers acknowledge identify the root cause of the issue and fix it as soon as possible. If and when they do, we will update this article to reflect the same so make sure to keep an eye out on this space.
