grant vortex 50/90 Oil Combi & Tado V+3 thermostat

Yes that's connect into heating system. So I think I need to call an electrician and he will connect it Tado, I just recently bought this house, so I still don't know everything very well. The house is old, I'm a carpenter myself, not an electrician, so I'll leave and better to let the professionals do the work. Thanks guys.

Under the water cylinder it's fireplace boiler pump

Does this mean the hot water cylinder is heated by a fireplace backboiler?
Does the Vortex only supply water to the C/H?

Your latest photos show the supply cable from the FCU, connected into the box and permanently hold open the redundant 2 port valve, with no connections on the micro switch.
The other cable coming out of the box supplies the boiler, meaning the permanent live in the boiler is connected to the switched live terminal 1.

If the Vortex was only contributing to C/H, it may be possible to clean this up via DIY.
However, if the fireplace is connected to the heating and you want the Vortex to also supply hot water, then it appears your whole system requires an overhaul.
I believe this is a job for a knowledgeable boiler engineer, rather than an electrician, given the redundant zone valve etc.

Both system do the same job, fireplace heating house and water at the same time. if I don't use it fireplace, when I turn on oil boiler and he then does the same work as fireplace. I just want to connect the thermostat to the oil boiler set in middle house 19-20 degrees And for monument I be happy, because now the oil boiler heats until the water temperature reaches a minimum of 65 degrees and stays that way, then it gets too hot at home, and then you have to turn it off it, gets colder then turn it on again. It's bullshit...

Totally agree you require a competent boiler engineer who understands this type of system and the controls required.
