Hi @varnden,
Thank you for posting in the community. I'm sorry to hear that you are having issues with your Heat Link because it has no lights and you are receiving a “no power” message on your Nest Thermostat, even though your boiler and hot water are still working manually. I appreciate the relevant information you provide. I apologize that you were unable to access our live chat or phone support options: that's definitely not the experience we want for our customers. I'm happy to assist.
To gather the necessary information, please answer the following questions:
- What type of Nest Thermostat do you have? The following article might be helpful: How to tell which Nest thermostat you have.
- When was it installed?
- Have you recently had service or maintenance on your electrical, plumbing, or heating system?
- Have you checked if the breakers are on?
I'll be waiting for your reply.
Best regards.
Derick.
