How easy to DIY replace a Nest Heat Link?

Sorry to bump the thread, but just to finish it off... Boxt engineer came on Thursday and replaced the Heat Link. In and out in about 15 mins. All working again.

Can't fault the service from Google or Boxt. We could have had a next-day appointment with Boxt but we couldn't be home for it and it wasn't urgent for us as we still had downstairs heating and hot water.

Long story short: If your Heat Link packs up, even if it's out of warranty, ring Google!

Great result, and thanks for letting us know.

Our other Nest Heat Link has died (two out of two within three years of installation!).

Just followed the process I posted earlier to report it to Google, and with one ten minute phone call I have a link and booking code to book another free visit from the lovely Boxt people, who'll replace it. 

So, Nests are pathetically unreliable but Google are still being good about it... Still, maybe just buy yourself a normal programmer since they last five times as long.

I'd hope they'd have got to the bottom of the issue - poor soldering, faulty batch of capacitors, whatevs - and they are now ok.

But I'll stick with my Hive

The Nest Heat Link is seemingly battery-powered. It can't possibly be that, PinkTea?

The heat link is mains powered but the thermostat has a backup battery in it. The most common failures do seem to be the heat link itself (as is the case here) or the back up battery in the thermostat, both of which seem to necessitate the replacement of the relevant part. As has been said, if I’d know how prone to failure they are, I would have thought twice about installing mine…

EDIT: D’oh, just realised I responded to a really old post.

Who are you calling an old post?!

Neffer been so insulted...
