Wink Heat pump, radiant boiler, bluelink - how that works and how to connect Nest

Hi, everyone! Glad I found the website and the forum.
I would appreciate some help from knowledgeable people.

I have a heat pump installed and also radiant heat boiler and some other stuff called Braeburn Bluelink.

Want to understand how everything is working and how to plug anything smart here, like, Nest.
Here is all information I have along with pictures:
1. Previous owner upgraded HVAC to a heat pump in 2017. Do not have any info on that besides these pictures
2. Boiler is radiant heat as far as I can see. Not sure if it is playing any part in heating the condo
3. Thermostat that is currently on is Braeburn 7220. Also there is a Braeburn Bluelink sticked to the heat pump
The wires that come from the wall are red [with label R], white [with label C], yellow [no labels] and green [no labels].

Questions that I have are:
1. Is it possible to install Nest here?
2. Do I need to run any additional wires for Nest? Nest website states that if one has any unmarked wires - then Nest can't be installed.
3. How is heating working with this setup? Is that radiant heat boiler playing any part in it?

Please forgive any silly questions or details.

Thank you

Welcome to the forums.

I would hope so..... why else would there be a boiler there ?

I don't see a boiler in your picture. I see a Bradford White water heater.
It looks like the Braeburn bluelink is a wireless thermostat setup.
Four wires won't be enough to use the nest there. That may be why the Braeburn was installed.

Thank you, Pete!
What I called a boiler might be a water heater, I'm no expert in what's the difference, thank you for correcting me.

Can you maybe direct me to some reading or explain how the whole heating cooling works in the setup I have?
I can't quite understand if I have a heat pump (I assume this a thing that can both cool and heat) then why do I also have a water heater taking part in that....

As for wires, What would be the best way to understand what are these two non-labeled wires?
Or even if they are good and connected to correct places, this is still going to be not enough for the Nest?

Thank you

I’d scrap the idea for the nest. They are a terrible choice for a thermostat.
What’s the model number off your air conditioner?

That is nothing more than a fan/coil unit. Just a water type air handler.
This type of unit requires hot or cold water from a larger plant.
Are you in an apartment or multistory dwelling ?

Yes, apartment in a 5 story building.
I think there is something on the roof but I can't find any documents on that and did not get any chance yet to visit the roof.

Anyway, the whole setup seems kind of complex to me.
Started noticing weird behavior with time - when noone is using any water or AC or heat, heater turns on for 5-10 minutes every hour or so.
Sometimes I can also hear puff puff puff like there is some kind of gas burning issue.

Will contact support to diagnose this stuff.

Thank you!

I don't think there is any gas in that unit. You may be hearing water gurgling thru the pipes. The fan running every so often may be some type of freeze protection system.
