My heating keeps being triggered whenever my hot water comes on. This never happened previously in a year of having this set up. Please can someone offer advice as my house is heating up when not needed and wasting money. My app also indicates that the heating isn't actually on
Hi Cristian, no work done recently or since installed actually. I can elaborate a little more in that what actually seems to be now happening is that my upstairs heating is coming on whenever the water is heating yet downstairs remains off. The upstairs/downstairs aren't independent of each other and run off the single thermostat
Very much a case of doing restarts on the thermostat. I even adjusted the temp setting on the original thermostat that is still connected. The issue returned last week so called Google support and they were barely any assistance. I've just received a booster for my home WiFi so am hoping that may be of some use and hopefully stop the issue once and for all as wonder if WiFi interference was responsible.
Thanks for your help. I don't know if it helps but a quick google suggests that my 3port valve between the water and heating (in front of water cylinder) is stuck/broken - it's not able to just heat water because the valve is stuck at W or the mid point so it's heating both the water and the radiators at the same time. I found a video on youtube explaining it... https://youtu.be/rw6NhmCa-qk
I feel so bad that I blamed my nest! Just in case it's not your wifi extender I thought I'd share.
Thanks again for replying to me!
Today we have two 3rd gen thermostats installs. Once upstairs (that plugs into the wall) that controls radiators upstairs, the second downstairs hard wired into the wall where an old thermostat was. The one downstairs is supposed to control our heating downstairs and hot water tank. Neither are working and radiators not coming on.
I didn’t a nest pro engineer did but something is definitely not working - it’s almost like it isn’t connected as looks working on nest and app itself but doesn’t seem to ‘speak’ to boiler! How would I know re wiring? Can I upload a pic that would help?
.If you are comfortable in doing so, make sure to turn off the power to the Heat Link first if you do. Then take the cover off and take a picture that shows the wires clearly and which terminal each wire goes into. I might be able to notice if there is anything that needs changing.
Also if you wish to have a look at how the wiring should look, we have some examples in our installation guide, have a look here: https://bit.ly/3nt2N4t
