Hi Georgia, I have the exact problem now with my heat link system, what did you do?

Hi Darren - it’s such a pain! You have my sympathy. I have no solution just yet - am going to check fuse etc but if no joy am hoping they will replace it.

I had the same issue, contacted their help desk and they’re sending out a new heat link and thermostat for me.

Hello everyone,
Thanks for reaching out. I'll do my best to get this sorted for you as soon as possible.
Here are some helpful troubleshooting steps:
Press the button on the Heat Link and check if you have any lights on it
Check if the circuit breakers and the switches are set to on
Turn them off and then back on
Press on the button again and check for LEDs
Could you also help me with some answers to these questions?
How long has your thermostat been installed for?
Did the issue happen during the installation?
Is there any error on the Nest thermostat display?
Have you had any power cuts recently?
Have you had any work done on your electrical or heating systems recently?
If yes, was the power properly restored at the fuse board after work was done?
How many zones are present in the setup?
Regards,
Cristian

Hi do you know word from we can’t buy replacement heat link 3rd gen
01-04-2022 04:44 AM
Hey @Pdc1604.
I'm sorry to hear you're encountering this issue as well, but I'd like to help you out. Can you please confirm that the breaker switches are set to on and also if you tried to turn the power off to the Heat Link for a few minutes and back on to see if it made a difference? You can test that by pressing the button on the Heat Link afterwards to see if the Manual Mode works,
Hey @Ewelinadestiny,
You can try to reach out to local retailers and Nest Pros if you want to buy just a Heat Link as we don't sell that separately. You can tell me what's going on if you wish and I might be able to help you with a replacement if needed.

Hey Ana, you’ve gone quiet on me… did you get my reply?

Hi sorry
we managing around 200 flats all of them have nest thermostats, our team is very familiar with the device, recently 2 heat links been found dead. Power been coming through but no light on heat link thermostat dead, we had spare ones we replaced them and it’s working fine, the case is how can I get replacement
01-08-2022 05:56 AM
Hi, Your 2 that failed sound just the same as mine, but mine’s a 50% failure rate not 1% 2 in 200! Where did you get your replacement Heatlinks?
01-08-2022 07:39 AM
Hi. We needed to get heating up and running asap we had guests in the house so we bought new set, it’s a shame since we now have 2 nest heads perfectly fine but no heat links. How can I get heat link replacement
01-08-2022 02:25 PM
Just like us, things always break at the worst times! And it’s a shame, and frustrating that the Nest head thermostat part which appears the most complex and costly component seems very reliable, but the Heatlink (probably little more than a box containing printed circuit board) lets the whole thing down. Both my son and son-in law decided this Christmas to change to smart thermostats and have decided to go for Hive instead of following my lead, right now I can’t say I blame them 🙁

Hey @Pdc1604,
The same email address was used from the beginning of our email email interaction, that's also the one you've put in the form when you were asked to complete it. The last email my colleague sent you was about the account verification, did you get that?
01-26-2022 10:19 AM
Hi @AnaM
Thanks for the update and confirming the form was received. No sorry, I didn’t get the account verification, but any time anyone responds I do get an email in my Gmail inbox to tell me I’ve had a response… a bit of a mystery! Could you resend please? Phil

hi, my heat link (about a year old) is dead with no lights at all. I have tried everything in the instructions/chats but nothing changes the H71 or the lack of lights in the heat link. I really want to put some heating on so please can you tell me how to get it replaced and if I can override it until that happens?
Many thanks
Sandra

Hi @Sand2000,
Sorry for the late reply. I'll do my best to get this resolved for you. Can you tell me what troubleshooting steps you've tried so far?
Regards,
Cristian
10-27-2021 07:19 AM
Hello again. Just checking in. Do you still need assistance?
10-27-2021 07:50 AM
hi Cristian,
Thanks for the message. I was sent a new heat link this week, which I just had installed yesterday. However the Nest thermostat does not connect to it because it just keeps going to the H71 error. The engineer gave up in the end.
I’m not sure where to go from here.
Kind regards
Sandra

Hey @Sand2000,
I'll do my best to get this sorted for you. What color is the LED on the Heat Link?
10-27-2021 08:52 AM
Flashing blue
10-28-2021 07:32 AM
Thanks for confirming. Let's try these steps:
1. Bring the display and base closer to the Heat Link and make sure the boiler is not in between the Heat Link and thermostat - only if possible.
2. Turn off the router and other WiFi or Bluetooth devices ( router, speakers, cordless phones, baby monitor, etc. ).
3. Select Replace Heat Link.
4. Enter the entry key ( do not confirm it yet ) — you can find it at the bottom side of the Heat Link, near the screw.
5. Restart the Heat Link twice by pressing on the Nest button for 30 seconds each time.
6. Confirm entry key.
Let us know how it goes.
