Hi @Jackbeecroft86,
Thanks for reaching out to the community! I understand you're looking for help on how to wire your Nest Thermostat E's Heat Link to a Worcester boiler from scratch. I'd be more than glad to share some details with you.
Since the Heat Link often involves working with high-voltage mains electricity, I don't recommend attempting the wiring yourself. For your own safety and to ensure everything is installed correctly, I suggest having a trained professional handle this part of the installation. Please contact a Nest Pro in your area for further assistance with the installation. They have the necessary tools and expertise to ensure your Heat Link works perfectly with your heating system.
I hope this information helps you.
Sincerely,
Jonathan
