Boiler wiring for thermostat

[Claire1999]

Hi was having a look at the wiring for my boiler (baxi duo tec a 24) to see if a nest thermostat would be suitable.
My currant thermostat has a mind of it own.
The wiring doesn't look right to me, just popping it all in a terminal strip together.

Normally my dad would have a look (he was a electrician) but he's isolating, So I dont want to ask him, as he will want to come and sort it out if it's wrong.

would be grateful for any advice

Hello Claire,

You could use some wago connectors, but the terminal strip is acceptable. All you need is power to feed the receiver, a common (additional live) and a call for heat (yellow from thermostat into grey for the boiler).

Thank you
Think I will just tidy it up.
As I'm not going to be hard wiring the thermostat in, could I just use the feed for the old thermostat to the heat link and add a loop from Live to 2? (Plus I just love drawing diagrams )

I can see that

Sorry, didn’t answer your question, yes it’s fine to use the old connections in the heat link.
