H71 error on Nest thermostat and no lights on Heat Link

[Snaz]

Hi

I’m getting a H71 error on Nest thermostat - there are no lights on Heat Link. 

Do i need to replace my heat link? If so, where is the best place to source o e from?

many thanks for any help.

H71 is loss of power, which may point to your Heat Link being dead. I assume you have checked fuses/mcb's etc.? Ebay is your best bet, as the Heat Link is not sold separately.
